The Chandra X-ray Observatory is one of NASA's four "Great Observatories," a space telescope that looks for X-ray emissions from galaxy clusters, exploded stars, and the areas around black holes. This week, scientists arrive in Boston to celebrate the 10th anniversary with a four-day symposium. Here are some of the visual highlights from its first decade of exploration.
The Perseus galaxy cluster is home to thousands of galaxies, and is alive with celestial turmoil. The wisps of blue in the center are thought to be caused by a galaxy that's been torn apart and is falling into the giant galaxy in the center.
