Discovery poses challenge to galaxy formation theories

A team led by an Indiana University astronomer has found a sample of massive galaxies with properties that suggest that they may have formed relatively recently. This would run counter to the widely-held belief that massive, ...

Surprise: Small elliptical galaxy actually a giant disk

Astronomers have believed since the 1960s that a galaxy dubbed UGC 1382 was a relatively boring, small elliptical galaxy. Ellipticals are the most common type of galaxy and lack the spiral structure of disks like the Milky ...

Galactic dinosaurs not extinct

One of the biggest mysteries in galaxy evolution is the fate of the compact massive galaxies that roamed the early Universe.

New 3-D map will help solve long-standing cosmic mysteries

A new study led by ANU has created a 3D map of the magnetic field in a small wedge of the Milky Way galaxy, paving the way for future discoveries that will improve our understanding of the origin and evolution of the Universe.

Mergers between galaxies trigger activity in their core

Active galactic nuclei (AGNs) play a major role in galaxy evolution. Astronomers from SRON and RuG have now used a record-setting sample of galaxies to confirm that galaxy mergers have a positive effect on igniting AGNs. ...
