Every star’s death is dramatic. Superluminous supernovae take the theatrics to another level. In the early 2000s, scientists first saw these conspicuous cataclysms, which can shine much longer and ...

Superluminous supernovas are the brightest stellar explosions in the universe. Astronomers may have found a mechanism that can trigger these events.

In December 2024, the ATLAS astronomical survey detected a distant flash of light. It was a supernova, the explosive death of a massive star, located far, far away, roughly a billion light-years away.

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 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 ...

WASHINGTON, March 11 (Reuters) - A supernova - the explosion marking the end of a massive star's life - is one of the brightest cosmic events, usually about a billion times more luminous than the sun.

A cosmic mystery surrounding the universe's most dazzling explosions, superluminous supernovas, appears to have been solved by scientists studying a colossal stellar event a billion light-years from ...

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

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 supernovas are particularly dazzling—the glow from a magnetic, spinning ball of neutrons called a magnetar. An assist from Einstein is what settled the case ...
