Astrophysicists have found the first evidence of a water-rich rocky planetary body outside our solar system in its shattered remains orbiting a white dwarf. A new study by scientists at the Universities of Warwick and Cambridge published in the journal Science analysed the dust and debris surrounding the white dwarf star GD61 170 light years away.
An international research team led by astronomers from the Max Planck Institute for Radio Astronomy recently used a collection of large radio and optical telescopes to investigate a pulsar and its white dwarf companion.
Life may well exist on planets orbiting dying stars - and, if it does, there's a good chance we'll find it within the next decade, say astrophysicists.
Astronomers reckon they've found the cause of the brightest stellar event ever recorded: a supernova first observed on April 30 1006 that continued to shine for three years.
X-ray and ultraviolet observations from NASA's Swift satellite have given new infoprmation about the origins of Type Ia supernovae.
Astrophysicist Rosanne Di Stefano compares it to the Hollywood blockbuster 'Speed' - a newly-described type of star that's destined to explode if it slows down.
