Decrepit stars locate the fountain of youth
[ Wed, 23 Dec 2009 20:46:23 GMT ]

The globular cluster Messier 30, imaged by the Hubble Space Telescope, formed 13 billion years ago and is about 28,000 light-years away. It is a dense swarm of several hundred thousand stars ? all about 90 light-years across. Mysterious old stars that look oddly young found the fountain of youth via two means, new research finds. Some rely on vampirism to suck the life out of a companion star, while others are rejuvenated in cosmic collisions.
