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

When we observe distant celestial objects, there is a possible catch: Is that star I am observing really as reddish as it ...

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

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 ...

This preferred direction of spin might be due to one of two reasons: either our entire universe exists in a black hole, or ...

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

Scientists from Keele University have found strong evidence that some of Earth’s past mass extinctions could have been caused by nearby supernova explosions—massive star explosions in the Milky Way.

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 ...
