Pioneering a new technique, researchers have peered into the extremely faint light that exists between galaxies to describe the history and state of orphan stars.
An unusual galaxy is set to prompt a rethink on how structures in the Universe form.
Big galaxies get bigger by merging with smaller ones, modelling has shown.
Associate Professor Sarah Brough wants to know how time has shaped our galaxies – and she is a gender equity champion for the next generation of astronomers.
The light of lone stars helps astronomers trace the distribution of dark matter in massive galaxy clusters – thanks to a new method discovered by UNSW scientists.
Scientists have discovered why heavyweight galaxies living in a dense crowd of galaxies tend to spin more slowly than their lighter neighbours.
