Astronomers have discovered the brightest and most distant "megamaser" to date. The cosmic energy beam is shooting toward ...

Astronomers with the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) have used data from the project to make the ...

A galaxy made almost entirely of dark matter, an elusive form of matter that doesn’t interact with light, was spotted by Hubble 250 million light-years from Earth.

The universe's first galaxies were hot messes, according to a recent study. During their younger days, they were wild, chaotic bundles of turbulent gas, churned up by huge gulps of intergalactic gas, ...

Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

The discovery made by a large research team challenges the existing models of the universe.

Astronomers using the James Webb Space Telescope have spotted the most distant “jellyfish galaxy” ever seen — a cosmic oddity ...

When you look up at the night sky, it appears unchanging. But if you look deep enough you will find that the sky is in fact ...

The researchers said that the "hydroxyl gigamaser" was generated by the merger of two galaxies some 8 billion light-years away.

Mysterious blasts of radio waves from across the universe called fast radio bursts help astronomers catalog matter. ESO/M. Kornmesser, CC BY-SA Chris Impey, University of Arizona If you look across ...

A multifractal spectrum called a weighted Cantor set model can describe how galaxies cluster, which is similar to other ...

Counting all the galaxies in the universe is hard. So hard, it seems, that it's possible to miss billions of them. A new analysis of Hubble Space Telescope data finds there are almost 10 times more ...
