A galaxy roughly 9 billion light-years from Earth is hemorrhaging its own future. Nearly half the molecular gas inside the ...

Billions of years ago, a young spiral galaxy began to grow in a crowded part of the universe. It pulled in gas and small ...

About 100 million light-years from Earth, a galaxy is losing everything that once defined it. NGC 1266 used to be a spiral, ...

In a feat of galactic archeology, astronomers are using ever more detailed information to trace the origin of our galaxy—and to learn about how other galaxies formed in the early stages of the ...

Galaxy formation and evolution dynamics describe the sequence by which primordial density fluctuations in the expanding Universe collapse into dark matter haloes, drawing in baryonic gas that cools, ...

Professor Woong-bae Zee of the College of Liberal Studies at Sejong University has revealed that a galaxy does not possess only a single evolutionary pathway; instead, depending on the nature of its ...

These three galaxy images from the AEGIS survey show a range of galaxy types: a disk-like spiral galaxy (top), a cloud-like elliptical galaxy (middle), and an irregular galaxy resulting from a ...

Image: Snapshots of the time evolution of a collision of two spiral galaxies with black holes at their center from a computer simulation. Color indicates temperature and brightness the gas density.

A team at the University of Arizona's Steward Observatory, led by Weizhe Liu and Xiaohui Fan, reported in Nature that they ...

Sci-fi tends to paint the edge of our galaxy as a desolate backwater, but in one early galaxy, the galactic rim is the bright, bustling center of activity, and the core is the aging backwater. The ...
