If you hear the word “superstar,” what immediately comes to mind? Perhaps names like Tom Hanks, Taylor Swift or LeBron James? That’s certainly ...

A deep-space photo of the Jellyfish Nebula in Gemini shows a brain-like structure, capturing the supernova remnant IC 443 and surrounding interstellar gas and stars.

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

For the first time, we have a front-row seat to one of the most violent events in the universe: a supernova. But there’s a ...

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 ...

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.

The star’s surface temperatures had increased by more than 1,000 degrees Celsius (1,800 Fahrenheit), turning its signature red color to yellow. It also shrank as a result of becoming hotter, going ...

The 94-year-old emperor of movie music has written his first piano concerto, and Emanuel Ax and the Philharmonic played it at Lincoln Center.

An extraordinarily rare, gravitationally lensed supernova may offer a powerful new way to measure the universe’s expansion rate.

New research from the University of Kansas untangles a decades-old astrophysical puzzle, showing how competing forces -- ...

Astronomers used Webb to find the star behind supernova 2025pht, revealing how thick dust can hide massive red supergiants.

Microscopic crystals extracted from meteorites could help settle a debate about the birth of our patch of the Milky Way.
