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

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

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.

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, ...

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 ...

One of our universe's biggest stars has dramatically turned into a rare, yellow 'hypergiant' star, and astronomers aren't sure when it will go supernova.

NASA’s James Webb Space Telescope captured the first published detection of a supernova progenitor in galaxy NGC 1637, ...

Researchers report superluminous supernova SN 2024afav whose erratic behavior supports a long-standing theory of stellar ...

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 ...

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 ...
