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

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

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

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 ...

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

In 1610, astronomer Galileo Galilei used the newly invented telescope to show that the Milky Way was composed of a huge number of faint stars. For the next 300 years, astronomers assumed that the ...

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 ...

Caldwell 103 is a treasure of the southern night sky. Also cataloged as NGC 2070 and often called the Tarantula Nebula or 30 Doradus, this chimerical structure is nestled in the Large Magellanic Cloud ...
