A red supergiant star appears to have changed in just a few years – an astronomical blink of an eye – which suggests it may ...

"These two supernova remnants are helping us to better understand the dynamics of our home galaxy’s neighborhood," ...

The strange behavior of hypervelocity stars suggests a nearby dwarf galaxy must contain a supermassive black hole. If so, a ...

Hypervelocity stars (HVSs) were first theorized to exist in the late 1980s. In 2005, the first discoveries were confirmed. HVSs travel much faster than normal stars, and sometimes, they can exceed the ...

It may have had concentrations up to 30 times higher than the water seen floating in interstellar space within the Milky Way, the researchers wrote in the study, which has not been peer-reviewed yet.

Astronomers discover two new supernova remnants in the Large Magellanic Cloud, providing insights into stellar explosions and their role in shaping galaxy evolution.

Sagittarius A* is the supermassive black hole at the center of our home Milky Way galaxy. It has a mass equal to billions of suns and has an accretion disk made up of gas and dust surrounding it.

A stunning new discovery reveals that white dwarf stars — once thought to explode in predictable ways — actually detonate through an astonishing variety of mechanisms. From star cannibalism to violent ...

Astrophysicists have unearthed a surprising diversity in the ways in which white dwarf stars explode in deep space after ...

Astronomers detect signs of a massive, invisible black hole in the Large Magellanic Cloud, which may collide with the Milky ...
