Scientists from the University of Durham may have solved a decades-old puzzle regarding the distribution of the eleven small satellite galaxies that surround the Milky Way. The Milky Way is not alone.

At approximately 100,000 light years in diameter, the Milky Way’s vastness and the broader, ever-changing dynamics of the cosmos defy any attempt to fully understand our home galaxy and its history.

This object is 10 billion light years away, so it's actually quite old by now, but it serves as an excellent analog for studying younger galaxies that are too dim. Share on Facebook (opens in a new ...

The Milky Way is home to gas, dust, billions of stars, and a supermassive black hole at its center. Living in this galactic home gives us exclusive insight into its components, but it also hinders our ...

The earliest stages of the universe are often envisioned as chaotic, filled with young galaxies that lacked order or recognisable structure. Yet recent high resolution imaging from the James Webb ...

Astronomers studying galaxy evolution have long struggled to understand what causes star formation to shut down in massive galaxies. Although many theories have been proposed to explain this process, ...
