Text, News from the Universe.
June 22, 2022. Galaxy cluster collision revealed. The pinpoint bright lights of planets appear across a vast dark sky.
Text, It takes x-ray vision to see what is really happening in this patch of sky.
One galaxy cluster is passing through another, releasing a huge amount of energy and pushing out a shock wave 1.6 million light-years long. A great billowing cloud of violet gaseous substances trails a giant white sphere.
Text, NASA's Chandra X-ray Observatory studied the collision for a total of 23 days, creating the deepest X-ray image yet of shock fronts in a galaxy cluster.
A magnified close-up of three clusters, with labels denoting Cluster #1, Cluster #2 tail, Cluster #2 core, Direction of motion of Cluster #2, Shock Wave, and Upstream Shock. Text, Special edge-detection image processing emphasizes the shock fronts. Chandra clocks the random gas motions in these clusters at 650,000 miles per hour.
