Is dark matter hiding in plain sight?
An orbiting gamma-ray telescope that has stared into deep space for four years may have picked up signs of dark matter in the Virgo Cluster of Galaxies.
Planet-hunters find new worlds in old data
Two scientists have ‘shone a light’ in the foggy spectra of an exoplanetary star system, GJ 676A, potentially revealing two new planets and hints of a third.
Telescope’s birthday gift is dust the job
An advanced camera on the James Clerk Maxwell telescope on Hawaii has unveiled new dusty bands of star formation in a distant galaxy.
When straying Jupiter went on the pull
A new computer simulation suggests that a wandering Jupiter once flirted with the inner Solar System, helping form its rocky planets.
Cosmic CSI squad name supernova star
The original star behind a relatively nearby supernova explosion has finally been identified as a white dwarf.
Black hole is spitting ‘super-bullets’
Astronomers have spotted a black hole spitting out super-fast ‘bullets’ from the disk of material torn from a neighbouring star.
Do dead stars play cosmic pinball?
A desert-based project could be close to solving the century-old mystery of where cosmic rays come from.
Challenging mysteries of the Universe
Could our Universe co-exist with other universes that forever expand in a sequence of “Big Bangs” or “Big Crunches”?
Did Hubble find water on super-Earth?
Hubble observations suggest that a ‘super-Earth’-sized planet lying 40 light years away could have large amounts of water.
