Latest Blue straggler Stories
Astronomers at the European Southern Observatory (ESO) have managed to capture a new infrared image of 47 Tucanae, the second most massive globular cluster in the galaxy.
Astronomers using the Hubble Space Telescope have found that some globular clusters are still young at heart, despite being relics of the early Universe.
This colorful view of the globular star cluster NGC 6362 was captured by the Wide Field Imager attached to the MPG/ESO 2.2-meter telescope at ESO’s La Silla Observatory in Chile.
Mysterious “blue stragglers” are old stars that appear younger than they should be: they burn hot and blue. Several theories have attempted to explain why they don’t show their age, but, until now, scientists have lacked the crucial observations with which to test each hypothesis.
NASA's Hubble Space Telescope has found a rare class of oddball stars called blue stragglers in the hub of our Milky Way, the first detected within our galaxy's bulge.
WASHINGTON, May 25, 2011 /PRNewswire-USNewswire/ -- NASA's Hubble Space Telescope has found a rare class of oddball stars called blue stragglers in the hub of our Milky Way, the first detected within our galaxy's bulge.

Using the NASA/ESA Hubble Space Telescope, astronomers have uncovered two distinct kinds of "rejuvenated" stars in the globular cluster Messier 30.
For almost 50 years, astronomers have puzzled over the youthful appearance of stars known as blue stragglers.
Researchers have discovered that the mysterious overweight stars known as blue stragglers are the result of â€˜stellar cannibalismâ€™ where plasma is gradually pulled from one star to another to form a massive, unusually hot star that appears younger than it is.
Like a whirl of shiny flakes sparkling in a snow globe, Hubble catches an instantaneous glimpse of many hundreds of thousands of stars moving about in the globular cluster M13, one of the brightest and best-known globular clusters in the northern sky.
