A record-breaking galaxy cluster some 11.1 billion light-years away has been spotted by astronomers having the mother of all star burst parties.
Named CL J1001+0220, this cluster can be seen forming when the universe was less than three billion years old, becoming the oldest cluster of galaxies yet seen, beating the previous record holder by 700 million years.

Galactic clusters are huge; among the biggest known structures in the cosmos. They are so big that astronomers thought CL J1001 wouldn't have had the time to accumulate so many galaxies. But there it is. And it's having one heck of a star party.
"This galaxy cluster isn't just remarkable for its distance, it's also going through an amazing growth spurt unlike any we've ever seen," said astronomer Tao Wang, of the French Alternative Energies and Atomic Energy Commission (CEA), in a statement.
