Tour of Phoenix Cluster
Tour of Phoenix Cluster
This galaxy cluster, which was found about 5.7 billion light years from Earth, shattered several important astronomical records. (2015-10-01)

G54.1+0.3 in 60 Seconds

Narrator (Megan Watzke, CXC): Data from the Chandra X-ray Observatory and the Spitzer Space Telescope were combined to create this image of the dusty remains of a collapsed star. This object, known as G54.1+0.3, is a supernova remnant some 20,000 light years from Earth. The white object near the center of the image is a dense, rapidly-rotating neutron star called a pulsar that was left behind after the star collapsed. The pulsar generates a wind of high-energy particles, seen in the Chandra data, that expands into the surrounding environment, illuminating the material ejected in the supernova explosion. This infrared data shows a shell of dust and gas that's being dispersed back into space where it one day may become part of a new generation of stars and planets.
