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 ...

Now, researchers have discovered a strange energy source at the center of our galaxy that could be linked to a different type ...

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

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 ...

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

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

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

"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 ...
