The Radcliffe Wave is a massive, undulating structure filled with dense clouds of gas and dust, stretching across several ...

A strange energy source at the center of the Milky Way may be a new type of dark matter. Scientists found that hydrogen gas ...

Astronomers say they have traced a mysterious pulsing in the Milky Way to a surprising source: a dead star locked in a dance ...

Andromeda XXXV is only about 20,000 times more massive than our Sun—very small, even for a satellite galaxy. For comparison, ...

Previous efforts to map the galaxy's dust were challenged by limited data, but the Gaia mission has provided a treasure trove ...

Millions of years ago, our Solar System traveled through a densely populated galactic region and was exposed to increased interstellar dust.

Astronomers have constructed the first detailed 3D map of the properties of cosmic dust in our home galaxy. For their map, the astronomers used 130 million spectra from ESA's Gaia mission, results ...

New research suggests that powerful star explosions, called supernovae, may have caused at least two mass extinctions in ...

Learn more about this new form of dark matter, which may positively charge hydrogen clouds.

The disc of plasma surrounding the black hole at the heart of the Milky Way is constantly emitting flares both large and small.

At least two mass extinction events in Earth's history were likely caused by the "devastating" effects of nearby supernova ...

"If a massive star were to explode as a supernova close to the Earth, the results would be devastating for life on Earth," said Nick Wright, an astrophysicist at Keele University in the United Kingdom ...
