Ticking Stellar Time Bomb Identified
Using ESO’s Very Large Telescope and its ability to obtain images as sharp as if taken from space, astronomers have made the first time-lapse movie of a rather unusual shell ejected by a “vampire star...

Read more2 Earth-sized bodies with oxygen rich atmospheres found -- but they're stars not planets
Astrophysicists at the University of Warwick and Kiel University have discovered two earth sized bodies with oxygen rich atmospheres – however there is a bit of a disappointing snag for anyone looking...
Physics and Astronomy | Read moreRapid star formation spotted in 'stellar nurseries' of infant galaxies
The findings show that "stellar nurseries" within the first galaxies gave birth to stars at a much more rapid rate than previously expected, the researchers from Durham's Institute for ...
