New research from an international team of astronomers from the UK's University of Leicester and the University of Arizona sheds light on how stars reaching the end of their useful life and collapsing in on themselves become polluted.
The European Space Agency (ESA) switched off its Planck space telescope for good at 12:10:27 UT, Thursday. Planck spent over four years peering back in time, studying background radiation from the Big Bang that gave birth to our Universe.
Astrophysicists from the universities of Warwick and Cambridge in the UK have found evidence of what was once a water-rich rocky planet outside our solar system, by analysing the atmosphere of white dwarf star GD 61.
Using the European Southern Observatory (ESO) Very Large Telescope and the Canada-France-Hawaii Telescope, astronomers have discovered an orphaned planet meandering through space without a parent star or solar system.
When a Time magazine reader asked astrophysicist Neil deGrasse Tyson to share "the most astounding fact about the Universe," he answered in a video. The vividly illustrated presentation has gone viral, receiving hundreds of thousands of hits.
The European Space Agency announced its fifth Automated Transfer Vehicle has been named Georges Lemaître, after the Belgian scientist who provided the first observational estimation of the Hubble constant, which was later called the Big Bang theory.
Dark matter is defined by NASA as “Name given to the amount of mass whose existence is deduced from the analysis of galaxy rotation curves but which until now, has escaped all detections.” That’s about as accurate as its definitions get.

New research shows that some old stars known as white dwarfs might be held up by their rapid spins, and when they slow down, they explode as Type Ia supernovae. Thousands of these "time bombs" could be scattered throughout our Galaxy. In this artist's conception, a supernova explosion is about to obliterate an orbiting Saturn-like planet.
