Astronomers found hypervelocity stars racing toward the galactic centre, inferring they could have come from other galaxies
New simulations of distant dwarf galaxies show they can have their gas stolen by a larger galaxy, similar to the two Magellanic Clouds encompassing the Milky Way
When observing galaxies very similar to the Milky Way, researchers have deduced that they are slowly expanding in size
New studies of satellite galaxies in Centaurus A show results that challenge our current understanding of almost 27 per cent of the universe
Astronomers now have the best evidence to date that the energetic events known as gamma-ray bursts produce a very narrow beam or jet
