Peek-a-moon

I don’t have a whole lot to add to this amazing shot from Cassini of Saturn’s moon Rhea reappearing from behind the giant moon Titan:

cassini_rhea_titan

[Click to entitanate.]

Except: coooool. Titan is over three times the size of Rhea, and Rhea was more than twice as far from Cassini when this was taken, making Rhea look even smaller in comparison. Also, check out how the high-altitude haze in Titan’s atmosphere isn’t the same height all the way around the moon. Near the top you can see they poof up higher. If you look closely, can you see the Enterprise?

    Okay, is it bad that my first thought was ‘giant space boob’? (No, Phil, not you…) :D

    That seems to be what Phil had in mind. Still a cool picture.

    I love that picture! Only, I can’t see the Enterprise :/

    No, you cannot see the Enterprise, because, I was on the Enterprise when I took the picture.

    Whoah, I came here from my Google Reader feed to post exactly “giant space boob” too!

    I felt that the picture was quite titillating _BEFORE_ I read the first comment!

    That’s not real! We know there’s no such thing as Cassini. Phil simply photoshoped this pic out of a Jenny McCarthy playboy and is trying to pull the wool over our eyes. Bad Astronomer…bad!! :P

    Don’t say ‘wool’ and Jenny McCarthy in the same sentence!

    Our Titanian hydro-carbon industry is eagerly awaiting the arrival of Exxon-Mobil to assist us in developing our export industry. We hope to ship 23 trillion metric tons a year your way,,,

    Great pic! Reminds me of my ex-wife,,,

    @Nick #11 – that whirring sound you hear is Richard Strauss spinning in his grave. But I see where you’re coming from.

    You know, it’s hard to tell yourself that no, Titan is not out of focus. Just naturally fuzzy.

    I thought I saw the Enterprise for a second, and then I realized it was just a spot on my laptop screen.

    I thought Rhea was the Enterprise for a sec there! ;-)

    Great picture – looks almost like a volcanic plume like on Io.

    Another “top ten picture of 2009″ candidate if you do a second one after the year is up as you’ve hinted. ;-)

    (Yes please sir I want some more! Actually, to be quite honest that first one didn’t really live up to my expectations, sorry BA. Oh & happy new year too!)
