Ready for another Where In The Universe Challenge? Here’s #63! 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. As usual, 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.
UPDATE: The answer has now been posted below
This is the Bullet Cluster, as seen by the Chandra X-Ray Observatory. This image is very fitting for this week, as Chandra is celebrating it’s 10th anniversary. What you’re seeing here is two large clusters of galaxies that have crashed into one another at extremely high velocities. At a relatively close distance from Earth (3.8 billion light years away) and with a favorable side-on orientation as viewed from Earth, the Bullet Cluster provides an excellent test site to search for something very interesting: the signal for antimatter. Find out more about that and the image here.
