Astronomy Picture of the Day -- Saturn's Hyperion: A Moon with Odd Craters
NASA ^ | June 30, 2013 | (see photo credit)

Posted on 06/30/2013 9:00:49 PM PDT by SunkenCiv

Explanation: What lies at the bottom of Hyperion's strange craters? Nobody's sure. To help find out, the robot Cassini spacecraft now orbiting Saturn swooped past the sponge-textured moon in 2005 and 2010 and took images of unprecedented detail. An image from the 2005 pass, shown above in false color, shows a remarkable world strewn with strange craters and a generally odd surface. The slight differences in color likely show differences in surface composition. At the bottom of most craters lies some type of unknown dark material. Inspection of the image shows bright features indicating that the dark material might be only tens of meters thick in some places. Hyperion is about 250 kilometers across, rotates chaotically, and has a density so low that it might house a vast system of caverns inside.

I see no resemblance...

If one were inclined to Science Fiction writing you could hide a nice big base and invasion fleet in that thing. Our solar system, a speck smaller than an atom in comparison with the observable universe, is an endlessly fascinating place. Of course, in the opposite direction so is the bottom of your average garden pond.

Captured comet?

These craters look like they were formed by out-gassing, and if so, what remains is the core of a captured comet.

Looks like barnacles have been growing on it. Could there be such a thing as space barnacles?

I was thinking that it looks like coral.

Looks like a barnacle or coral of some sort. Almost organic cellular structure.......

Looks like something that was molten at one time, out gassed furiously in the vacuum of space while cooling down and eventually solidifying.

Wonder what molten lava would look like in a large vacuum chamber while it cooled, seems like a simple experiment.

Probably could get a close approximation with mixed 5 minute epoxy hardener and resin, pulling a vacuum while it hardened..........Just thinking.

Those are impact craters. The question is what is the composition of Hyperion. What it is composed of will define what the impact craters look like.

Solid rock would not give that type of impact picture. Perhaps a rock and ice mixture could give this picture. If Hyperion were solid rock, we would see rays from the impact craters, as on the moon, that are caused by ejecta from the impact. It would appear that Hyperion is a semisolid.

"Looks like my bath sponge."



It definitely has the appearance of biological origin.

Maybe it's a cosmic virus. Or a bit of space coral .....

My first guess would be that its largely made of fine dust like flour with low enough gravity that the craters don’t collapse.

I was thinking along those same lines. Every one of those holes could be made into a separate ecosystem if you cover them over with a film of some sort to protect the artificial environments inside. Unless of course it really is made of some kind of spongelike material.

If an invasion, it’s been danged slow getting here. Of course, that’s just my Earthcentered thinking there, maybe they have no interest in us.

It appears to be more like pumice; now I regret not seeing if NASA’s made density and mass measurements during a flyby.

Could be, probably aren’t, but that would depend on what they’d live on, food wise.
