A great encounter between a starry sea diver, at the top, and some­thing big­ger below is play­ing out in this image. That’s what I see. What sto­ries can you tell about this image?

Swooping Eagle

Galaxy inter­ac­tions are always impres­sive. ESO 593–8 looks like a swoop­ing eagle or a feather. Explore the NASA Hub­ble Space Tele­scope image of these merg­ing galax­ies. Do you see any pat­terns? What sto­ries can you tell?

A galac­tic gator looms in this image of the inter­act­ing galax­ies of the Hick­son Com­pact Group 31. Four dwarf galax­ies are in the process of col­lid­ing, light­ing up the sky as new stars come to life.

Starry Sea Otters

The pair of inter­act­ing galax­ies NGC 6621/2 play like a pair of starry sea otters in this image from NASA’s Hub­ble Space Tele­scope. NGC 6621, to the left, is the larger of the two; it’s spi­ral shape highly dis­turbed by NGC 6622. The encounter has pulled out a long tail of NGC 6622 wrap­ping around the body of the main galaxy.

Monkey Face

Do you see a mon­key face look­ing up? Or sparks and smoke left over from a fire­works dis­play? The col­or­ful fil­a­ments seen in this NASA Hub­ble Space Tele­scope image of N49 are all that’s left of a super­nova explo­sion that took place thou­sands of years ago in the Large Mag­el­lanic Cloud. This super­nova rem­nant is called N 49, or DEM L 190. Inside these sheets of glow­ing star debris lies a pow­er­ful, spin­ning neu­tron star called a pul­sar. Pul­sars give off reg­u­lar pulses of energy like the tick­ing of a very pre­cise clock. After the super­nova blows off the outer lay­ers of the star, it col­lapses under its own grav­ity. The star col­lapses so much that the pro­tons and elec­trons spin­ning around the atoms of the star com­bine to form neu­trons. A neu­tron star is very dense. Imag­ine our entire Sun packed into an area of just 20 kilo­me­ters (12 miles) in diam­e­ter! Grav­ity is very strong on a neu­tron star. On Earth, a spoon­ful of neu­tron star mate­r­ial would weigh bil­lions of tons. The mag­netic field of N 49 is super strong, tril­lions of times stronger than Earth’s, putting it in spe­cial class of bizarre celes­tial objects called magnetars.

Star-osaur

To me, this image from NASA’s Hub­ble Space Tele­scope looks like a lum­ber­ing, long-necked Bron­tosaurus. Maybe a tur­tle with a long tail. What do you see in this image?

Of Snakes and Snails

by CritterKeeper on Jan.26, 2010, under Birds and other animals

The land­scape of Mars’ hazy Hel­las Basin twists and turns as if some­one spread warm peanut but­ter across it and let it ooze down­hill. Fea­tures, shown in this image from NASA’s HiRISE cam­era aboard the Mars Recon­nais­sance Orbiter, snake across the plain. Some shapes curl up in shell-like shapes. Explore the strange land­forms. Between some of the snake-like, flow­ing shapes, you can find sand dunes and craters.

Martian Polar Horse

Fly­ing across the ice fields of Mars, we find all sorts of strange and famil­iar shapes. I imag­ine this horse leap­ing in the thin ice lay­ers in the south­ern polar region shown in this image from NASA’s HiRISE cam­era aboard Mars Recon­nais­sance Orbiter.

Whether you see horses, dol­phins or a jel­ly­fish, the green and blue bub­ble of NGC 2371 catches the eye in this NASA Hub­ble Space Tele­scope image.

Dusty Cotton Candy

To me, this looks like a wal­rus with big whiskers com­ing up out of the dust. Or, since I have a sweet tooth, maybe a big bunch of dusty cot­ton candy.
