The discovery of a newborn magnetar inside a distant supernova helps explain why some stellar explosions shine far brighter ...

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.

The light did not fade the way it was supposed to. After blazing into view about a billion light-years from Earth, the ...

Astronomers have discovered a strange new signal coming from an exploding star — a “chirp” that speeds up over time, similar to the signals seen when black holes collide. The unusual pattern appeared ...

New research suggests that the highly magnetized remnants of stars are responsible for powering some of the universe’s most brilliant supernova explosions ...

WASHINGTON: A supernova — the explosion marking the end of a massive star’s life — is one of the brightest cosmic events, ...

Superluminous supernovas, or ultra-bright cosmic explosions, have puzzled scientists for years. Recent studies of a supernova a billion light-years away reveal that a magnetar, a dense neutron star, ...

A new study explains how some supernovae are particularly dazzling—the glow from a magnetic, spinning ball of neutrons called a magnetar. An assist from Einstein is what settled the case ...

The James Webb Space Telescope has captured new imagery of supernova remnant Cassiopeia A. It is 11,000 light-years away in the Cassiopeia constellation. Credit: Space.com | footage courtesy: NASA, ...

Yet what we can see with our eyes, or even with powerful telescopes, when these stars die, is only a tiny fraction of the ...

Asrtronomers managed to pinpoint which star in the NGC 1637 galaxy turned into a supernova 40 million years ago, they used the Webb telescope.

Analysis reveals what appears to be a channel of hot, low-density plasma stretching out from our solar system toward distant ...
