LAWRENCE, Kan. (AP) _ An assistant physics professor at the
University of Kansas is studying one of the earliest known clusters
The school says the early galaxies are 10 billion light years
away. Observing them allows Greg Rudnick to look back to 4 billion
years after the Big Bang. That's because it takes light from the
early galaxies' stars so much time to reach Earth.
Rudnick considers this period vital because it included the
quickest pace of star creation in forming galaxies.
He hopes his research will help answer questions about how stars
Rudnick makes his observations with the help of a vast radio
astronomy observatory in New Mexico.
