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 ...

An international team of astronomers has achieved a first in probing the early universe, using the James Webb Space Telescope (JWST), detecting a supernova—the explosive death of a massive star—at an ...

Researchers say the "powerful engine" behind superluminous exploding stars had been hidden for years — until a "chirp" from the cosmos helped confirm their link.

Astronomers have discovered that the birth of neutron stars with magnetic fields trillions of times stronger than Earth's magnetosphere is the "magic trick" behind superbright supernovas.

NASA’s James Webb Space Telescope has recently made a historic observation, identifying the earliest supernova ever detected. This discovery, made possible by Webb’s advanced imaging capabilities, was ...

Their formation has been an object of debate, but new observations confirm the lead hypothesis: they are the product of incredibly bright supernovae. The rest of this article is behind a paywall.

For decades, astronomers have used distant supernovae as cosmic lighthouses to test fundamental physics and to measure the ...

A rare gravitationally lensed supernova could help astronomers determine how fast the universe is expanding and shed light on dark energy. Astronomers may be closer to understanding one of the ...

A supernova that erupted when a massive star died could have destroyed our infant solar system — if it weren't protected by a cocoon of molecular gas. When you purchase through links on our site, we ...

Some stars in our galaxy, known as hypervelocity stars, move much faster than most other stars in the Milky Way. In fact, they are traveling so fast that our galaxy’s gravity can’t hold onto them and ...
