Image: Saturn's sponge-like moon Hyperion

[Robittybob1]

This is a remarkable image of Hyperion.

There doesn't seem to be too much else on YT but could you get a better image than this?

That's a stunning object. Found some more here. It looks almost volcanic in origin, like pumice.

Craters from myriads of asteroid impacts, melting into the ice???

In addition to the surface analysis, Cassini also helped scientists work out why the moon has such a bizarre spongy appearance. It all comes down to an extremely low density. According to new calculations, the moon has only half the density of water. Its low gravity means that normal processes, such as crater formation work differently than on more dense objects in the Solar System. Objects that impact Hyperion plunge in, compressing the surface instead of blasting out the familiar looking craters.

Is there a secret to opening those other pictures?

What are you seeing when you click on one. That link I posted is to a DuckDuckGo search engine search result. Click on a picture and you get a slightly bigger one on the same page. Click on THAT picture and it should give you the full size one.

Do I remember that these images exaggerate the altitude much, and Hyperion's features are rather flat?

It must have been the settings on the other computer. This one is displaying images OK thanks.

I have several rocks i collected from the ocean that have that texture, you can pour water through them, the resemblance is amazing...

Are you talking about pumice?

[Externet]

Seems more an optical illusion than spongy as white coral.

 

Good, am not the only one using DuckDuckGo ! No Google for me !

No, it's some form of fossilized coral or colonial tube worms, all the tubes are more or less parallel, I have quite a large collection, i've been collecting them for more than 40 years... some are as big as basket balls but most while large are irregular shaped..

Yes I did see something like that in Google images yesterday. The one I wanted is not coming up but this one is close https://s3.amazonaws.com/s3.frank.itlab.us/photo-essays/small/sep_03_0146_white_coral.jpg

legend there of the same image put in this discussion:

"Hyperion with image processing to bring out details."

 

Check out the other images on WIki: this moon is normal.

"Normal" in what way?

Seems like that. Another image of the surface: http://cache.boston.com/universal/site_graphics/blogs/bigpicture/saturn_05_30/cassini9.jpg
