Where In The Universe Challenge #28

Here’s your image for 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 responsible for the image. The new way we’re doing this challenge is that 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 — if you dare. Check back tomorrow on this same post (reminder: no new post tomorrow — come back to this one) to see how you did!

UPDATE (11/6): The answer has now been posted below. If you haven’t made your guess yet, no peeking before you do!!


I have to say, I am impressed with the knowledge of you UT readers! Great job! Yes, it is Tycho’s Supernova Remnant, taken by the Chandra spacecraft. This is a bubble of hot gaseous supernova debris (green and red) inside a more rapidly moving shell of extremely high-energy electrons (blue). These features were created as the supersonic expansion of the debris into interstellar gas produced two shock waves – one that moves outward and accelerates particles to high energies, and another that moves backward and heats the stellar debris. The Chandra X-ray Observatory, which was launched and deployed by Space Shuttle Columbia on July 23, 1999, took this image in 2005.

And I’m sorry about the delay in posting the answer.
