These links all recover items I encountered while working as a volunteer "galaxy classifier" for the Galaxy Zoo project at GalaxyZoo.org a kind of work you might find fun also to do. Somewhat over 100,000 people have participated as volunteers there across the Internet so far. There is no scientific merit to my choices, just my own taste in images, so keep your expectations low. Even the link names are pretty ugly, my main task as I grabbed these was galaxy classifying, not wallpaper making, so this whole thing is a bit crudely done.
These are links to images of astronomy objects, almost all galaxies, which I found that are either pretty, interesting, or both. Some are fairly fuzzy and low detail, a very few are sharp and high detail, most are in between and toward the fuzzy end. The sensor that created these images has a bad CCD pixel, so some of the images have a black line across them. There are also _lots_ of artifacts from viewing space with a telescope, you're sure to notice some of them.
The links provided are not to fixed images, instead they go to the Sloan Digital Sky Survey web site containing digital data covering a narrow band of our available view of the universe. This is a database site, from which the images are reconstructed for you on the fly, so if that site is having problems, none of these links may work at the time. Obviously, hot linking the items will drag the SDSS site to its knees, so if you want to use an image, copy it to your own storage.
The images are all sized either 1280x800 pixels, or 800x1280 pixels, depending on which orientation works best for the item(s) being imaged. Since the database retrieval won't rotate the universe to fit your computer screen wallpaper needs, about half of these images will need to be saved and rotated a quarter turn to use them for computer screen wallpapers. The dimensions happen to fit my particular computer monitor screen. To change them to fit yours, fiddle with the width, height, and scale parameters of the URL in your browser's location widget (not in the SDSS controls) to make the width and height fit your monitor dimensions, and to make the scale fill the image as best possible, then resubmit the URL. Smaller scale numbers zoom "closer" to the image. The width and height are limited to 2048 pixels each way. This adjustment process may take you a few tries.
| Possible Problems |
|---|
| The SDSS database contains multiple overlapping versions of the parts of the sky imaged, from which it selects via an opaque-to-me algorithm a subset of images from which to re-create the displayed image you receive. The database also, rarely, fails to fetch the parts needed to build an image, and just outputs an error message where the fetched image was expected. These wallpaper image links all "work" as of the time they were added here, but the SDSS database may be a dynamic one, or its software may change, and if so future failures may occur. Such failures may also occur for you while you are changing and resubmitting URLs to make the wallpaper fit your monitor's dimensions. If the failures aren't due to a blunder by you, you might want to report such failures via the mechanism provided here: Contact Help Desk. Yes, the SDSS help desk really is contacted via a library in Chicago; why I don't know. No, no way is provided to attach an image showing the problem error message to the email you send, a sometimes frustrating oversight. |
This list may grow with time. There is a second phase of the Galaxy Zoo project upcoming in 2008, so the chance for participation by me or by you won't end soon. The set of objects to classify currently numbers around a million, while my viewing of them at this writing numbers only around 17,000 or so seen. Therefore, there are lots more classification objects that I haven't seen than ones that I have, and thus there is almost certainly lots more pretty stuff for me to find and turn into wallpaper links for this list.
I've finally caught up with annotating these links, working started from the top and bottom and met in the middle of the list, and I've fixed up the link names, while adding more links too. The annotation adds clutter but maybe also gives readers a better idea which wallpapers to pull forward for viewing. In no sense should my chatter about these images be mistaken for informed scientific commentary. I'm a math major, not an astronomer.
Triple Threat
A trio of modest galaxies, an edge on spiral, an
open oblique spiral, and an elliptical, make a nice
"crowded sky" wallpaper.
The edge on spiral of this trio of visually
neighboring galaxies has a little blob above it and
a rakish angle that makes it look exactly like a
flying saucer driven by an alien with his head out
the hatch.
Another Three'fer
A long elliptical or possible edge on spiral, and
two fairly fuzzy blue spirals make a vertical
arrangement. This isn't very pretty, but is another
example of just how visually dense the universe can
be with galaxies.
Shot from Guns
This modest yellow spiral galaxy seems to have
developed a way to shoot a line of stars or small
galaxies out of itself.
Star on Wedgie Both Blue
A long narrow blue elliptical galaxy superposed by a
blue star seems to be budding an offspring.
Lumpy Elliptical
This is one of the elliptical galaxies, blue in this
case, with so much internal structure that the
classifier's eye tries hard to manufacturing some
spiraling in it somewhere to explain the dense
clusters of stars.
Two Turn Two Arm Spiral with big blue stars nearby
This very attractive galaxy, mostly white, has a
simple structure with long skinny arms much like a
brittle starfish in the ocean does. Nearby large
stars show just how tiny most of the galaxies seen
even at this level of detail really loom in the sky.
Yellow-White Train Wreck with long tail
Two galaxies in collision seem to have hit each
other at a very acute angle, leaving a trail of
ripped away stars behind them almost larger than the
two galaxies' lengths combined.
Possible Merger Or Jet Makes Tail Of Stars
The reason this galaxy is squirting out stars like a
spaceship with an aircraft contrail behind it isn't
really obvious, making it perhaps an interesting
object for further study.
Elliptical Outline Embedded Spiral Arms
This pretty galaxy violates the naive expectation
that there will be some clear boundary between
elliptical and spiral galaxies. Instead they seem
collectively to blend smoothly from one kind to
another, with this galaxy as an example of an
intermediate form.
Face on spiral
No two of these big blue spirals are ever quite the
same, and this fairly pretty one is a good example
of the complex changes in form from one part of the
galaxy to another than can occur, from well defined
arms to chaotic mush.
Face on Spiral
This pretty blue spiral galaxy has a bit more
symmetry in its form than the previous one.
Face on Multi-limbed Spiral
This big pretty face-on blue spiral galaxy has three
well defined limbs, and several others that are just
fragments of full spiral arms, a very usual layout.
It is also a bit rounder than the two prior
examples, but it isn't clear whether this is just
because it presents itself more flatly to the eye,
or because some elliptical galaxies really are long
ovals even when see in a direction perpendicular to
their spin. We know from the solar system that long
elliptical orbits are perfectly possible, so perhaps
only careful measurement could resolve this question
for an individual galaxy.
Eccentric Multi-Armed Spiral Overlapping Elliptical
Here is an example of nested spiralization patterns,
where spiral arms within the elliptical main body of
the galaxy trail out on one side into a diffuse arm
containing several better defined arms or fragments.
This is also one of the much coveted superposed
galaxy arrangements, with an elliptical galaxy
partly behind the spiral galaxy (at its bottom in
the image). Scientists can use the fairly constantly
colored and smoothly blended intensity light from
the elliptical as a probe shining through the
spiral's arms, to study where dust does and does not
intercept the light or some spectral fraction of it,
learning lots about the dust from this information.
And what's with what looks like a chunk of a spiral
arm making its escape toward the bottom right?
Almost Ring Spiral
Ring galaxies (this isn't one) are a type just
beginning to be understood. Barred spiral galaxies
have their spiral arms at the end of a long or short
bar, rather than beginning near the center. This
wide-barred pretty blue-white spiral galaxy has
turned the spiral arms trailing from the ends of its
bar nearly into a closed ring as well, but I don't
think the two ring types are directly
related.
Batter up!
This striking blue spiral looks like a baseball
pitcher about to launch a yellow sphere (star or
galaxy) at the onlooker. Pay attention also to the
near right angle bend in the opposite spiral arm.
What's with that?
Tall Skinny Blue Very Open Spiral Galaxy
This pretty blue galaxy with lots of bright clusters
is a fairly commonly seen galaxy type, perhaps
seen nearly edge on, perhaps not, but with a visual
shape looking only barely different from a long
elliptical galaxy, as if the urge to turn and become
a spiral galaxy never really got very
strong.
Immense Face On Blue Spiral Galaxy
This galaxy is visually huge, a fair fraction of the
size of the full moon. It's probably visible to the
naked eye. It is not only beautiful because of the
nice detail, but also vastly reminiscent of a snail
speeding across the heavens in a full
charge, with its head to the right.
Galaxy With Offcenter Bulge
This galaxy is a mystery to me, the
"central" bulge around which the galaxy
spins seems instead to be almost all the way to one
edge of the galaxy. With its smoothly dense white
stars as a background, it almost looks like a ball
with the arms wrapped around its surface instead of
a disk with the arms embedded in it. What's with
that?
Round Blue Clusters With Bunny Ears
This almost entirely blue galaxy is interesting for several
reasons.
It has a lot of nearly empty internal space.
It forms a circle as round as a button.
Its main bulge of stars, the only white part, is
quite far off center.
Most fun, though, is that on top and just a shade
to the left, it seems to contain the headband with
attached bunny ears made so famous by Playboy Club
hostesses.
Face On MultiArmed Spiral With Large Blue Star
This very attractive and symmetrical face-on blue
spiral galaxy is made more tutorial by the presence
of a large blue star at its foot, lending a sense of
how small even a galaxy this detailed as seen by a
telescope really looms in space unmagnified.
Large White Spiral With Big Inner Disk And Short Arms
This vanilla pudding colored galaxy seems to have a
closed curve of stars separating the inner and outer
parts, with only a very subdued set of spiral arms
jutting out from that curve.
Enormous Close Up Tight Wound Two Armed Blue Spiral
I have no idea why some spiral galaxies have one
arm, some have two arms, some have many arms, and I
can only blame "different rotation speeds"
for why some of them barely spiral at all and others
are tightly wound like yo-yo string. Whatever the
causes, the result is a wide range of image types
that are all spiral galaxies. This spiral
galaxxy example is so big and close that it contains
more detail than can be fit into my size of computer
screen wallpaper, so this image was shrunk to fit
rather than the more usual expanded to fit cases.
Diagonally
Tilted Large Blue Spiral
This is one of the showy highly detailed blue spiral
galaxies whose arms are completely contained in the
larger halo of stars, giving the galaxy a smooth
edge.
Galaxy
Missed Because Of Nearby Bright Stars
The SDSS database doesn't even recognize this
pretty, if nearly transparent, blues spiral galaxy
to exist, probably because it is obscured by the
much greater light of the two bright stars next to
it in the sky.
Fat
Armed Spiral Dust Study Candidate
The fairly low detail blue spiral galaxy with two
interesting features. First, that it is superposed
with a smaller elliptical galaxy, making it possibly
useful for the Galaxy Zoo scientists to use in their
proposed study of spiral galaxy dust lanes. Second,
that the lower arm splits, one part going around the
galaxy center as expected from symmetry with the
opposite arm, the other trailing off as if some
passing other galaxy had ripped part of the stars
away into a long streamer. However, there is no
second galaxy in the vicinity to be a suspect in
such an interaction.
Mother and Daughter
Two spiral galaxies, the larger one a sparse, white,
thick armed, fairly tightly spiraled one, the
smaller one a blue unsymmetrical one, sit in very
close visual proximity, like mother and daughter.
Galaxy Versus Star
This is an example of a fairly frequent occurrance,
a pretty galaxy so close to a very bright star that
it goes unnoticed, where if it were out in a less
busy part of the sky, it would be noticed much
earlier. This image has another interesting artifact
besides the "cross" the telescope puts on
bright stars and the halo around the star. There is
the trail of an earth satellite right across the
face of the galaxy, transparent dark blue because it
crossed the image while the exposure was made, and
so the objects behind it were only obscured part of
the time.
Dart
Board
This splendid face on spiral blue galaxy looks for
all the world like it is being used as a dart board,
with the smaller galaxy to its right and down being
thrown at it as a dart.
Swirly
With Pixel Flaw
This pretty face-on spiral galaxy has a broken pixel
flaw right across it, but otherwise its well-swirled
arms reminds this observer of the legs of a hermit
crab seen in profile.
Nearly
White Spiral
The well defined spiral arms of this face-on galaxy
show only a hint of blue, making it a study in
white-on-white.
Large
Blue Oval-Barred Ill-Defined Spiral
This is another face-on blue spiral galaxy, with
great detail but with its arms not well defined in
long sweeping spirals, more in broken short sections
instead. It sits in a fairly busy part of the sky,
so the image is decorated by many small local stars.
Diagonal
Long Two Limbed Spiral
This spiral may be a bit blurry, but it makes up for
the lack of detail by a wealth of colors, white,
yellow, red, and blue against a black backdrop.
Laid
Back Spiral
This wonderful pool of swirling stars, probably seen
at an angle, is free of imaging artifacts.
Dense
Inner Arms Wispy Outer Arm Spiral
There's not much special about this pretty face on
blue spiral galaxy, except that almost all the
spiral arms are internal to the star halo, yet one
stray spiral arm is well separated from that halo.
Blindingly
Bright Blue Spiral
For some reason, the center of this blue spiral
galaxy seems to be entirely overexposed, as if it
were a searchlight pointed at the onlooker.
Red
Pimple On Laid Back Spiral
This fairly low resolution spiral galaxy is seen
on a slant, and the red star in front of it's top
top looks like a complexion blemish. Notice also
slightly down and left of the galaxy center, the
appearance of an eruption up through the surface of
the galaxy.
Triangular
Irregular Galaxy
Irregular galaxies don't seem to make gravitational
sense. This one, for example, is more or less
trianglular, with a woven snake of bright clusters
in one part of it.
Immense
Edge On Spiral
The level of detail in the dust trails along the
edge of this edge-on spiral galaxy is really unusual
and splendid. The large red star just at the corner
of the image lends scale.
Luminously
Colored Edge On Spiral
This edge on spiral doesn't have the detail of the
one above, but it has great color, from orange to
blue, and reminds the onlooker of some marine
organism darting after its prey.
Blue
Spiral With Many Small Overlaps
This highly detailed blue spiral galaxy overlaps
several yellow galaxies of much smaller visual size,
making it look like a net full of fishes.
Simply Immense Unrecognized Spiral-Ring White Galaxy
Look carefully around the smooth cream egg of this
galaxy, and you'll find that it is embedded in a
less dense but very distinct ring. It is always fun
finding something like this that has not yet been
identified as a separate object of interest in the
SDSS database.
Galaxy
With Floating Arms
Around almost a smooth center, this galaxy knots a
nearly circular ring, from which a wealth of arms
extend only a short distance, and irregularly, If
one looks carefully, the result looks like a
stylized cartoon baby duck with beak to the bottom
right and topknot to the top left.
Fraternal
Twin Spiral Galaxies
Two very detailed spiral galaxies, different in
color and in how closely they face the onlooker, lie
visually close in space to make a single wallpaper.
Spiral Galaxy With Orbiting Cluster
Accented by a red star that oversaturates its part
of the image, this blue spiral galaxy is mostly
compact, except for one large orbiting blue cluster
that may be arriving late to join the rest of the
galaxy.
Huge
Blue Spiral Next To Big Red Star
This gorgeously detailed face-on blue spiral galaxy
fights for notice in its part of the sky with a
large red star seen mostly just off screen.
Food
Processor Blade Plus Small Loose Companion
The larger blue spiral galaxy in this image looks
like it was put together out of angular parts. Its
smaller companion looks like it has been run once
through the blender, little substance seems to
remain to it.
Blue
Potato Sprouting
Unlike the airy look of most galaxies, this blue
spiral seems to be very solid, like a blue spud
hunkered down in space, sprouting arms from its
dense substance.
Local
Star Cluster
This isn't a galaxy at all, it is the much smaller
cousin to a galaxy, a star cluster right here in the
Milky Way, a knot of stellar density with its own
family of stars orbiting its own center while the
whole mass orbits the center of the Milky Way.
Spiral
With Southerly Star Wash
This whirling cream pool has a wash of loose stars
that form a wispy arm to the top right, but only a
blurred wash of stars to the bottom right, without
much visible structure.
Blue
Ice Stirred Not Shaken
It seems like some malefactor was trying to irritate
James Bond, serving this blue ice martini galaxy
stirred not shaken.
White
Spiral Near Two Bright Stars
This very painterly white spiral galaxy has two
bright nearby stars superposed with it to lend it
color.
Tadpole
Chase
The physics in this low detail possible galaxy
merger are surely otherwise, but it looks
like one galaxy is chasing the other across the
heavens.
Blue
Spiral Superposed Pink Star
This very bright blue spiral galaxy has a star of
unusual color superposed over it, a sort of a
spearmint pink.
Sparse
MultiArmed Blue Spiral
This just has to be one of the prettiest galaxies in
the heavens as seen from Earth. There is something
very spiderlike in its open nest of arms.
Spiral
Widely Dispersed Clusters
This low resolution blue spiral has a lot of
exterior clustering that is too sparse to form arms
but spreads out interestingly into space.
Edge
On Spiral Near Yellow Star
It is only when seen edge on that the central bulge
of spiral galaxies becomes evident. There is lots
more to such a galaxy than a spinning flat disk. In
this image, a color coordinated yellow star floats
as companion to this otherwise isolated seeming
galaxy.
Moderately
Well Defined White Ring Galaxy
Before the Galaxy Zoo project began, ring galaxies
like this were known, not understood, and considered
to be very rare. Lots more of them have now been
found, so maybe someday understanding can arise from
the now much larger set of samples available for
study.
Pretty
Open Two Armed White Spiral
Some galaxies have thin well defined arms with lots
of empty space, or of other non-arm galaxy material,
between them. Others, like this one, have thick arms
with only thin lanes separating them.
Sparse
Blue Spiral
Here in low resolution is the opposite situation to
the above one, a blue spiral galaxy with thin arms,
and with lots of empty space between them.
Low
Contrast Distant White Spiral
This low resolution white spiral seems to be made
"all of one substance" with little color
differentiation across the whole galaxy image.
Low
Contrast Blue Spiral With Ugly Bad Pixel Stripe
This blue spiral galaxy has low color contrast, and
an interesting right angle corner in one of its
spral arms, but it is marred by an extremely broad
dead pixel flaw drawn across it by the viewing
device's sensor.
Merger
Aftermath In Blue
The eye wants to scale this image intimately, like
it was a couple of glowing blue nematode worms
negotiating the best sparring position for a mating
duel on the back of a domino, but the scale for
galaxy collisions like this one is almost a
quintillionfold that big.
Edge
On Yellow Spiral
The galaxy classifier gets to see lots of edge on
spiral galaxies. Only rarely is the detail
sufficient to distinguish the dust lanes splitting
the edge into top and bottom halves, as in this
case.
Fiddler
Crab Blue Spiral Galaxy
The closer spiral arm of this blue spiral galaxy is
unusually crisp and intense, giving it the look of
the dominant arm of some space borne species of
fiddler crab, raised in warning to avoid or commence
battle.
The
Holy Grail As Two Merging Galaxies
These low resolution but unusually symmetric
colliding galaxies can be seen many ways, but one
fun one is as a drinking cup, the long sought Holy
Grail drawn across the heavens. There is even a
star to stand in as a jewel on the rim of the cup.
Unusual
Green Edged Elliptical Galaxy
Green is a color that catches the human eye, making
it all the more unusual how rarely it is seen when
classifying galaxies. Here though, the eye leaves no
doubt that the color intended for the outer halo of
stars in this low resolution elliptical galaxy is
green.
White
Ring Galaxy Superposed On Blue Spiral Galaxy
Superposed galaxies of roughly identical sizes are
rarely seen in this detail. These cases look
fingerpainted, one of them from an intensely blue
palatte, and the other is a rare ring galaxy.
Four
Galaxy Styles Lined Up
A sparse lenticular blue galaxy, a blue spiral
galaxy of loose organization, a white barred spiral,
and either an orange star or an orange dwarf galaxy,
line up like a dance hall number being rehearsed.
Open White Three Limbed Spiral
Like many mutants, this galaxy seems to have grown
an extra limb from somewhere, and the result has
left its shape awkward and confused.
Medium
White Spiral With Several Neighboring Objects
White spiral galaxies aren't too pretty in
themselves unless they are seen in very high detail,
but this galaxy's visual companions lend the image a
bit of needed color.
Mystic
Eye Of Power On A Rocker
This symbol in space seems very similar to eyes
depictied in Egyptian heiroglyphics and tomb
drawings. One end seems to spiral back to create a
rocker on which the rest of the image can rest.
Possible
Irregular Galaxy Source -- Slug And Ball Merger
This is probably the most detailed galaxy image I've
found myself, a merger between an elliptical galaxy
and a spherical galaxy that seem to be tearing out
of the substance of the two galaxies a product of
blue clusters that will be left behind when the two
colliding galaxies have long fled the scene. This
looks like one possible origin for the mysterious
irregular galaxies: as debris from such
mergers.
Large
White Elliptical With Great Internal Detail
I'd like this to be a cream on cream spiral galaxy,
but there's no indication of chirality, just lots of
internal dust lane detail.
Narrow
Blue Spiral Galaxy
I'm fairly sure this lovely detailed blue spiral is
narrow because of the direction from which
we view it, not from its actual shape.
Distant Blue Spiral With Small Purple Discoloration
The detail isn't too great in this face on blue
spiral galaxy, but the symmetry is pretty and the
details are fun, a yellow elliptical galaxy seen
through a thin spot in the much larger spiral's
structure, and a minor purpling of the stars at
about the 5 o'clock position right at the edge of
the spiral galaxy.
Sloppy Face On Spiral
This very loose and open blue spiral galaxy seems to
have been tossed together as an afterthought from a
kit of leftover star clusters, as if it didn't quite
know where it was going. Unlike for many more opaque
face-on spirals, the background galaxies show
through this one as if through tattered lace.
Yellow White Edge On Spiral With Good Color
This relatively nearby edge on spiral has great detail in the roiling
dust clouds that cross its center.
Large Neighbors Edge On Spiral And Face On Spiral
These neighboring spiral galaxies, one face on, one
edge on, are shown separately in greater detail in
the above two links, but make a pretty wallpaper
arrangement when shown in their natural orientation
to each other as well.
Let's Just Back Out One More Level ... LOOK AT THAT!!!
An immense beautiful face-on complexly-armed blue
spiral galaxy. I really did say aloud to myself just
before finding this "Let's just back out one
more level...<censored>!"
Limpid Pool
Some spiral galaxies have raggedy bits sticking out
every direction, but this pretty blue one is
smoothly embedded in its halo of stars, like a limpid
pool.
Smooth Edged Blue Spiral
This blue spiral has its arms entirely contained
within the smooth oval of the galaxy boundary.
Pretty but Lopsided Ring Galaxy
These galaxies, thought to be very rare before the
Gakaxy Zoo project, are now identified in greater
numbers but still their origin is only partially
understood, with a face to face collision between
two spiral galaxies apparently the current best
idea.
Dust Study Candidate Pair
This blue spiral galaxy overlapping a white
elliptical galaxy is of scientific interest,
because the light from the elliptical galaxy can be
used as a kind of probe to study the dust clouds in
the spiral galaxy through which it shines.
Utterly Spectacular Edge On Spiral Galaxy
Does the dust band across this galaxy really take a
break conveniently at the center, or is the center
just so bright it saturated the image collecter in
the middle right through the dust? This galaxy spans
around 7.5 arc minutes tip to tip, making it
visually huge. Notice how busy the sky is here, with
lots of other more distant stuff visible right
through this comparatively nearby galaxy's halo of
stars.
Distant Letter S Spiral Galaxy
As a vanity signature for the project web forum,
lots of Galaxy Zoo participants like to compose a
collage image from low detail galaxy images they've
found while classifying, that spells out their name
or Internet nickname. The letter "S" is
one of the easiest ones to find.
Super Clean Edge-on White Spiral Galaxy
This is obviously, from its shape, a spiral galaxy
seen edge-on. What is unusual is that there is no
sign of a dust band along where the spiral's edge
should be. In comparison, our Milky Way looks like
it was rolled on its edge down a fresh tarred road,
when looked at from the only direction we have
available.
Blue Face-on Spiral with Small Red Stars
There's nothing remarkable about this good sized,
pretty, face-on blue spiral galaxy, but it does have
a sprinkle of red stars near the top.
Very Obliquely Viewed Large Blue Spiral Galaxy
This is what a large, comparatively nearby blue
spiral galaxy (about 4 arc minutes in length) looks
like seen from an angle that makes it nearly but not
quite edge-on to the viewer. Notice the two other
easily seen galaxies in this image. That's a crowded
sky out there.
Blue Face-on Spiral Galaxy with Blindingly White Bar
This large pretty face-on blue spiral galaxy is most
noteworthy for the intense white glare cast off by
its elongated core area. In shape, the galaxy evokes
the image of a dancer going into a twirl to flare
her skirts, arms above her head.
Blue Streak
This bright blue galaxy full of hot young stars
doesn't give many hints as to its type. Elliptical?
Edge on spiral? Irregular? It's hard to tell when
there's so little to see except a blue streak of
stars painted across the field of view.
Shades of Blue
Two modest blue spiral galaxies very close in size
and shape are neighbors, differing mostly in that
one is almost all blue like a roiled light blue
pudding, while the other is mostly a field of white
stars with blue clusters only in the arms wrapped
around the center part.
Big Well Spread Blue Spiral Galaxy
This large, fairly isolated blue spiral galaxy is
noteworthy mostly for the sweeping
"gestures" of its two main spiral arms,
and the even spacing of all the secondary arms.
Three Superposed Non-Trivial Galaxies
At a scale of half an arc second per pixel, this
large mostly creamy white spiral galaxy is simple
visually immense, around 8 arc minutes in its long
diameter, which makes the edge on orangish spiral
galaxy at 10 o'clock and the white elliptical at 5
o'clock both overlapping it, both big objects in
themselves.
Crisp White Spiral Galaxy
This only slightly less visually immense galaxy was
encountered in the same pulled back view of the
data set as the above image. It doesn't have the
overlapping galaxies, but makes up for that by
having more pronounced spiral arms, that clearly
extend out past a well defined elliptical main body
of stars.
Star's Partner
This highly detailed blue spiral galaxy competes for
the viewer's attention with a bright star whose
imaging artifacts obscure a small part of the more
defined of the galaxy's two wide flung spiral
arms.
Nicely Symmetrical Blue Spiral Galaxy
This nicely symmetrical blue spiral galaxy has its
spirals more defined by darkness than by light,
because it is light almost everywhere.
Ratty White-on-Blue Spiral Galaxy with Edge-on Smaller Companion
I almost oriented this wallpaper the wrong way, but
good luck had me seeing the companion galaxy 1/4th
the diameter of the larger galaxy before I commited
to that choice. The main item of interest in the big
galaxy besides its disheveled appearance is that the
two main spiral arms appear as white against blue,
where the opposite color contrast is the usual
case.
Creamy Ambiguous Chirality Large Spiral Galaxy
One would think it would be easy to tell which way a
big, nearly face on galaxy with so much internal
detail, like this one, is turning, but the contrast
between the dust lanes and the stars is so low, the
eye changes its guess constantly.
Chalk on a Rock
This white thick-armed fairly open spiral galaxy
looks as much like an Australian natives' pteroglyph
depiction of The Dreamtime, as it does an image from
the heavens. Look carefully, and you'll see that
the spiral starts at the inside as a single arm, but
splits in two after one turn and continues as two
spirals solidly to the exterior.
Complex
Blue Galaxy with No Obvious Spiral Arms
This long oval blue galaxy has many blue clusters of
stars, but no obvious structure that would lead one
to give it a "spiral" classification
Large
Open Armed Blue Spiral Galaxy with Peep-through Distant Galaxies
This large blue spiral has arms separate enough from
the main body of the galaxy that some much more
distant galaxies show nestled in those arms.
Spectacular
Galaxy Collision that Nearly Destroyed the Smaller
Galaxy Involved
A spectacular "train wreck" seems to have
destroyed and stretched to great length a small
galaxy, while the larger galaxy involved seems to be
fairly intact, but with its arms ripped mostly away.
An uninvolved elliptical galaxy, sitting in front of
the wreckage toward the bottom, obsucres but
decorates part of the mechanics of the
collision.
Local
Globular Cluster Near Large Red Star
This large globular cluster, somewhere within the
Milky Way, dominates the surrounding area of the
stars even at the farthest pullback of the SDSS data
set. A large red star, visually bigger than all but
the most nearby galaxies, but much smaller than this
cluster, gives some sense of scale of just how huge
a globular cluster looms in the heavens.
Triplets
Here's another pretty triple of galaxies, one
edge on spiral, one distinct elliptical, one very
pretty face on spiral, near to each other visually
in the sky, making a pretty wallpaper.
Blue
Spiral with Many Well Groomed Arms
The leftmost of the triple of galaxies above makes a
pretty wallpaper by itself, too, and looks like it
just came back from a trip to the hairdressers.
Merger
Like an Arm Dropped Off
This obvious galaxy merger left a trail of stars
between the two involved galaxies, but because one
is perhaps edge on, and they are the same creamy
color laced with the red of dust lanes, it looks
like one is an arm that "dropped off" the
other. Despite being low resolution, the result
makes a very striking wallpaper, since the local
area of space is otherwise very dark.
Blurry
Spiral Galaxy Barely Beginning To Spin
Elliptical galaxy types supposedly blend smoothly
into spiral galaxy types. This image, of a distant
galaxy and therefore of low resolution, shows an
elliptical-shaped envelope within which a spiral
center has just barely but distinctly begun to turn,
an example of an intermediate type of
galaxy.
Large
Globular Cluster with Many Red Stars
This visually huge globular cluster (about 20 arc
minutes across) has many large red stars in the
foreground that seem to be part of it.
Spiral
Galaxy Like Rolled Cookie Dough
This pretty spiral galaxy is very neatly rolled up,
much like the two-colored cookie dough my
grandmother used to make. A smaller elliptical
galaxy stands guard nearby.
Messy
Blue Spiral Galaxy with Tiny Center
This low visual density blue spiral galaxy seems to
be fraying apart in every direction. The tiny size
of its central white area is noteworthy as well.
Two
White Spirals Merging
In the distance, and thus at low resolution, two
adjacent white spiral galaxiess exchange stars,
producing a misshapen halo of stars that surrounds
them both.
Blue
Spiral Galaxy Smooth as an Egg
This pretty, screen filling blue spiral galaxy has
its spiral arms entirely contained in its star halo,
producing a smooth symmetrical edge.
Irregular
Blue Galaxy Somewhat Resembling a Waving Elf
There's little rhyme nor reason to the shape of this
galaxy, with arms sticking out every which way, but
if you make the lower left the feet and the upper
right the head, you can almost make out an elf with
one arm waving or about to throw something, a
trailing stocking cap from the head, and one arm by
its side. The face isn't much to brag on though,
just the usual white core of the galaxy.
Galaxy
Much Too Big to Hide Behind a Star
This lovely highly detailed blue spiral galaxy is a study in
contrasts, a very compact center with a well
defined boundary and the spiral arms contained
inside it, plus numerous islands of star development
floating free around that main image. It is so
close/large that the big red star superposed on it
is more a decoration than a hiding place. Many, many
other smaller galaxies are still well defined in the
image, yet the main impression of the region
surrounding the main galaxy image is still inky
blackness. There is also a highly unusual detail of
the spiral arms, that rather than starting from
opposite ends of a bar or from points spaced around
the edge of a central whirl, they all are rooted
from a single point distant from the center, which
then forms rather a turn around point for the arms
than a terminus for any one arm, as if a folded
layer of stellar dough were rolled startnig from the
fold point to make a spiral. Note also for a laugh
the small pair of nose-glasses floating exactly at
the top of the galaxy.
Large
Open Armed Medium Detail White Spiral Galaxy
This isn't the most detailed galaxy, but it jumped
right off the original Galaxy Zoo classification
image as a beauty. But what is that grey cloud south
of center and before the arms begin?
Wild
Day in the Local Universe
This sprawling blue spiral galaxy looks to be
running out of control in a busy part of the sky.
Galaxy
Suffering from Anorexia
Colorful, but proportioned like a pencil, this
galaxy seems to need to digest a few smaller
galaxies to gain some weight.
Big
Elliptical Galaxy with Quasi-spiral Internal Structures
This big pretty blue galaxy has everything a spiral
galaxy could want, except spirals!
Motor
Boat Merger
This is either a remnant of a long past near
collision that ripped two parts of an existing,
perhaps originally elliptical, galaxy into skewed
alignments with the main body, or else this is a
merger well underway, but with one fragment spalled
off to be for now a mini-galaxy orbiting the rest of
the two merging galaxies. In any case, the dense and
brilliant blue of short lived new stars where the
two offset galaxy fragments join shows that a
violent shockwave has been experienced in that
vicinity quite "recently".
Cat's
Eye Barred Loose Blue Spiral Galaxy
This pretty, loose limbed blue spiral galaxy shows a
prominent bar with some visible dust lanes along the
bar, has inner spiral arms forming a distinctive
"cat's eye" shape, and is superposed by
several bright stars.
Owl
With a Halo
This trio of a smaller elliptical galaxy, and a
barely superposed large spiral galaxy and large
elliptical galaxy, make a pretty wallpaper. When
seen on my laptop screen from the bedroom door at an
angle, which changes the color and intensity of the
image, it looks like an owl "mask" with
red eyes, dressed up with a halo.
Aslant
View of a Horizontal Blue Spiral Galaxy
This nice blue spiral galaxy, seen from an angle,
has a much smaller yellow spiral galaxy floating
above it looking sort of like a left
apostrophe.
Benthic
Denizen
This blue, possibly spiral galaxy has obviously seen
better times. A part of it has been pulled like
silly putty into a grotesquely large spiral arm
looking much like a tadpole "tail", it has
a bright, nearly white star for an eye, an
underslung jaw, nostrils, a gill slit, and in
general looks very like a ratfish floating head
downward ready to pounce on some passing
shrimp.
Milky
Merger
Whoops! Two pretty yellow-white spiral galaxies are
in the process of ripping one another into something
that will probably be much less attractive when the
merger is completed.
Zebco
With two bright blue loose spiral arms, one
exceptionally elongated, this galaxy's shape looks
less like a product purely of spin than of one arm
being flycast into the universe while the other is
used as a handle to do that casting.
