The Hubble and Euclid space telescopes caught a stunning portrait of a dying star at the heart of the Cat's Eye Nebula.

Billions of light years away in a remote part of the universe, two neutron stars – the ultradense remnants of dead stars – collided. The catastropic cosmic event sent light and particles, including a ...

The Vera C. Rubin Observatory has started releasing its first discoveries: including supernovae, variable stars and asteroids ...

New studies reveal how metallicity and stellar evolution determine whether massive stars expand into red supergiants prior to ...

A dying star’s final breath creates a haunting, brain-shaped cosmic silhouette.

The oldest stars in the Milky Way are forcing a fresh look at one of cosmology’s biggest arguments. If some of them are about 13.

WOH G64 has always been an oddball. It sits in the Large Magellanic Cloud, a small galaxy that orbits the Milky Way, and it ranks among the most extreme red supergiants known.

When most people think of a supernova, they're thinking of a Type II core-collapse supernova. These are massive stars that have reached the end of their time on the main sequence. They've used up ...

UT astronomer Keith Hawkins will discuss how astronomers map the stars in our galaxy to understand its formation and evolution across cosmic time.

A sweeping new ALMA image has peeled back the veil on the Milky Way’s core, exposing a dense network of cold gas filaments ...

A steady stream of particles forms a huge bubble around the Sun. Now, such a structure has been found around a Sun-like star ...

The birth of massive stars involves gravity, turbulence, and stellar feedback, all of which influence the flow of matter. Find out more here: ...
