Where In The Universe #130

by Nancy Atkinson on December 23, 2010

Here’s this week’s Where In The Universe Challenge. Take a look and see if you can name where in the Universe this image is from. Give yourself extra points if you can name the spacecraft, telescope or instrument responsible for the image. We 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. And please, no links or extensive explanations of what you think this is — give everyone the chance to guess.

UPDATE: Answer now posted below!

This is the Moon, specifically the big rock in the middle is a close-up of a 320 meter block of ejecta in Tycho crater covered by a veneer of impact melt. The image was taken by the Lunar Reconnaissance Orbiter Camera earlier in 2010.

Tycho crater is one of the most visible features on the near side of the Moon, and its ray system extends far and wide. So much so that the Apollo 17 astronauts sampled its ejecta, over ,2000 km away from the crater! That is amazing!

See more images of Tycho and learn more at the LROC website.
