Stars around our galaxy previously thought to be from merged dwarf galaxies are likely to have once been part of the Milky Way before being pulled away by an invading satellite galaxy
A new international study involving ANU has found a plane of dwarf galaxies orbiting around Centaurus A in a discovery that challenges a popular theory about how dwarf galaxies are spread around the Universe.
ANU will play a major role in the Taipan galaxy survey, which will for the first time measure the current expansion rate of the Universe with one per cent precision.
Astronomers at The Australian National University (ANU) have created the most detailed radio image of nearby dwarf galaxy, the Small Magellanic Cloud, revealing secrets of how it formed and how it is likely to evolve.
