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?
