Astrophysicists have unlocked the mystery behind superluminous supernovas. SpaceX's Starship faces delays, impacting NASA's lunar mission timeline. Spanish researchers developed a low-cost artificial ...

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, ...

In December 2024, astronomers watched a star around 25 times the mass of our sun die in a blaze of glory. Located one billion light-years from Earth, SN 2024afav was a prime example of a superluminous ...

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

A UC Santa Barbara graduate student alongside a local nonprofit research group have advanced the frontiers of physics while ...

Astronomers have for the first time seen the birth of a magnetar—a highly magnetized, spinning neutron star—and confirmed that it's the power source behind some of the brightest exploding stars in the ...

Betelgeuse, one of the brightest stars in the constellation Orion, has long fascinated astronomers because it is nearing the end of its life. Observations from the Hubble Space Telescope revealed a ...

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

A never-before-seen 'chirp' in the light of an exploding star has revealed new clues about the engine powering some of the brightest supernovae in the Universe. According to an an ...

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

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.

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. But some - a small ​fraction - ...
