Hubble finds rare stars in Milky Way

Peering deep into the star-filled, ancient hub of our Milky Way (left), the Hubble Space Telescope has found a rare class of oddball stars called blue stragglers, the first time such objects have been detected within our galaxy's bulge. Blue stragglers -- so named because they seem to be lagging behind in their rate of aging compared with the population from which they formed -- were first found inside ancient globular star clusters half a century ago. The picture at right shows the 42 blue straggler candidates circled in green.
