View Full Version : Discussion: Young Stars in an Old Galaxy

2004-Sep-04, 04:29 PM
SUMMARY: Astronomers have spotted a number of young stellar clusters dotted around a very old elliptical galaxy - this disputes the established theory that old galaxies contain only older stars. The team used the Hubble Space Telescope and the ESO Very Large Telescope to take a series of images of galaxy NGC 4365, and they were able to identify star clusters that were only a few billion years old, while the majority were over 12 billion years old. Why the galaxy contains such a combination of young and old stars is still a mystery.
