Astronomers making a detailed, multi-telescope study of a nearby galaxy have discovered a magnetic field coiled around the galaxy’s main spiral arm. The discovery, they said, helps explain how ...

It's a fun question to tackle because it lets us dig into the messy, complicated, beautiful process of galaxy formation. When you purchase through links on our site, we may earn an affiliate ...

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 ...

Researchers have used the ALMA telescope and found old elliptical galaxies in the universe can form from intense star formation within early galaxy cores. An international team of researchers ...

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.

Astronomers spotted nine galaxies with characteristics that have never been seen as a collection before. It's possible this ...

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

Galaxy formation unfolds through a complex interplay between gravitational dynamics, gas physics and energetic feedback from stars and black holes. Dark matter haloes collapse under gravity, drawing ...

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 ...

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