Where In The Universe Challenge #100

Here’s this week’s Where In The Universe Challenge, and can you believe it — this is the 100th WITU we’ve done! Amazing! But no resting on our laurels, or yours either for that matter (thanks to you, our readers for making the WITU Challenge such as success!) But you know what to do: take a look at this image and see if you can determine where in the universe this image is from; give yourself extra points if you can name the instrument responsible for the image. We’ll provide the image today, but won’t reveal the answer until tomorrow. This gives you a chance to mull over the image and provide your answer/guess in the comment section. Please, no links or extensive explanations of what you think this is — give everyone the chance to guess.

Good Luck!

Update: The answer has now been posted below:

Answers were split down the middle, but the winners are those who said Mars. Yes, this is an image of icy layers at Mars’ north pole, taken by the HiRISE camera on the Mars Reconnaissance Orbiter. The HiRISE folks say that the Martian north polar layered deposits are an ice sheet much like the Greenland ice sheet on the Earth. Just as with the ice sheet in Greenland, this Martian ice sheet contains many layers that record variations in the Martian climate. So this is a very interesting image — and place — to study.

Find out more on this image at the HiRISE site.

And check back next week for another WITU challenge!

    Ditto. HiRISE cam.

    North Pole of Mars, from the MRO

  3. Lawrence B. Crowell says

    Agreed, this looks like the layers at the maritian polar caps.


  4. Jorge says

    The rings of Mars! 😉

    No, really, it’s Mars, a HiRISE photo of layered terrain on one of its polar caps. MRO.

  5. gopher65 says

    It’s probably Mars, but others beat me to the punch, so I’m going to go with a less likely answer:

    False colour image of Saturn’s cloud bands, by Casini.

  6. Ringman says

    At first I was going to say Saturn’s rings at equinox, but then I thought it’s probably some weird formation on Mars again, so I’m not sure,…

  7. elfman345 says

    Mars — Mars Orbiter

  8. Ted Judah says

    A weathered, eroded dome on, uh, Mars?

  9. Maddad says

    I will also vote for the rings of Saturn as taken by Cassini.

  10. Mister T says

    It’s a extreme close up of Neil deGrasse Tysons Saturn tie.

  11. neoguru says

    OK I’ll say it! Saturn’s rings by Cassini. Congrat’s on #100. I’ve been a fan since WITU was conceived and look forward to it every week. WTG with WITU! Keep ’em coming Nancy!

  12. Quasy says

    Earth glacier

  13. Devin Null says

    I’ll go with Saturn’s rings taken by Cassini.

  14. pikoia says

    It is a HIRISE picture of icy layers at the North Pole of Mars

  15. Andromeda says

    Strawberry icecream or icy layers in Martian north polar region recorded with HiRISE camera on NASA’s Mars Reconnaissance Orbiter on 11 March 2010.

  16. vino says

    My first thought is also Rings of Saturn…..
    (It is interesting to see the forum split in this case!! )
