Recent studies challenge the long-held belief that the Milky Way is a standard model for understanding galaxy formation, ...

Hubble’s work pushed the field of astronomy forward, starting with his paper demonstrating that some objects exist outside our galaxy.

High radiation during a time of frenzied star formation in the Milky Way left one stellar population with few chances to form planets, a study reports.

100 years ago, Hubble revealed a universe of galaxies that existed beyond ours — but he couldn't have done it without a little help. If we could go back 101 years, we would encounter a time when ...

A massive filament of gas and dust, designated X7, has been elongated during its long approach to the Milky Way galaxy's ...

"Within 2 billion years, Andromeda will have traveled the distance that separates it from the Milky Way and, just at their meeting point, they will cross each other," the expert explained ...

One of the largest galaxies ever found, the behemoth is about 1.44 billion light-years away and reckoned to be 32 times the size of our Milky Way galaxy. The mightly object is classed as a giant ...

Astronomers have achieved a groundbreaking feat by capturing the first clear image of a star in another galaxy. This ...

But around the cosmic time that we are seeing the Firefly Sparkle, Milky Way-like galaxy progenitors were about 10,000 times less massive than today’s Milky Way. Hopefully with the collaboration ...

By that metric, the ESA's Gaia mission is a resounding success. The spacecraft gave us a precise, 3D map of our Milky Way galaxy and has forced us to abandon old ideas and replace them with compelling ...
