Where In The Universe Challenge #93

Its time for another “Where In The Universe” challenge, and this one is actually on time this week! The WITU challenge will test your visual knowledge of the cosmos, and this week’s image was submitted by UT reader Rob Bowman. Rob is hoping to stump everyone this week, but try to guess/name where in the Universe this image is from, and give yourself extra points if you can name the spacecraft responsible for the image. Make your guess and post a comment, but please no links or extension explanations to the answer. Check back sometime on Thursday to find the answer and see how you did. Good luck!

UPDATE: The answer is now posted below.

This is a composite image of part of Jupiter’s moon, Europa, which shows the distribution of ice and minerals for the structure named Tyre. The image was created with data from the Galileo spacecraft’s Solid State Imaging (SSI) camera and the Near Infrared Mapping Spectrometer (NIMS). Tyre, the circular feature, is 140 kilometers in diameter (about the size of the island of Hawaii) and is thought to be the site where an asteroid or comet impacted Europa’s ice crust.

Lots of correct answers! Great job everyone, and thanks again to Rob Bowman for submitting the image. Check back next week for another WITU challenge.

    The texture looks like Europa.

    Or the final stage of Missile Command.

    I’ll guess a multispectral image of Callisto? by Galileo.

  • Jorge February 24, 2010, 11:53 AM

    This must be an impact structure in Europa, and the picture was probably made through some reworking of Galileo data. VERY false colour, of course.

    A false color image of Europa

    The Tyre Crater on Europa. Taken by Galileo

  • bystander February 24, 2010, 12:01 PM

    Europa – Galileo

  • Andy F February 24, 2010, 12:26 PM

    My guess, judging by the striations and colours… a Europan Pizza!

  • deep field February 24, 2010, 3:18 PM

    crater on Europa….

    By Galileo spacecraft…

  • Lawrence B. Crowell February 24, 2010, 6:38 PM

    I am a bit stumped, or I am not sure how this is distinquished from the surface of Europa from Callisto etc. These moons tend to have surfaces which look like this.

    I think Matthew Burns is right……..

    Enceladus [en-SELL-ah-dus] is one of the brightest objects in our solar system

  • RapidEye February 25, 2010, 9:56 AM

    I think I’ve seen this recently…. If not, it was something very much like it.

    I think it is a crater on earth in obviously false colors.
    From memory, the lines crossing left to right are dirt trails and the others going top to bottom were creek beds.

    I can’t for the life of me remember where the shot was taken – somewhere in the mountains: maybe Rockies or South Africa.

    Don’t have a clue what satellite.

  • Rob_Bowman February 27, 2010, 12:16 PM

    I was hoping to stump everyone with this image as it’s quite an olde one. Should have known better!

    Congratulations to Mathew Burns for the first correct answer!
