Hot, Heavyweight Cluster Found!
News story originally written on August 20, 1998
Astronomer Megan Donahue has discovered one of the heaviest and hottest galaxy clusters. Cluster MS1054-0321 is located 8 billion light-years from Earth. It has thousands of
galaxies and trillions of
stars! The temperature of the material between galaxies is about 300 million degrees Fahrenheit (so the galaxies themselves must be very hot!).
If you could name a galaxy cluster, what would you name it?
