CHARLOTTESVILLE, VA (NEWSPLEX) -- Some astronomers at the University of Virginia have made a discovery that gives us a glimpse of how some stars form.
They used a set of telescopes in Chile called ALMA that are placed at very high elevation in a desert, which has very little cloud cover. It's a globular cluster out of which that stars form.
"They're ancient,” said Kelsey Johnson, UVa professor of astronomy. “They're almost as old as the universe itself, so their basically fossil relics of what was happening at a much earlier time in the universe. The second thing about them that's really extraordinary is that they have millions of stars packed into tiny volumes."
This discovery took the telescopes only two hours to find and about a year of analysis.
