One of the largest known stars in the cosmos is poised for catastrophe. After witnessing the massive object undergo a ...

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

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

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 ...

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, ...

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.

Swift observations with the European Southern Observatory's Very Large Telescope (ESO's VLT) have revealed the explosive death of a star just as the blast was breaking through the star's surface. For ...

Astronomers used Webb to find the star behind supernova 2025pht, revealing how thick dust can hide massive red supergiants.

Scientists have revealed for the first time a jaw-dropping early view of an exploding supernova. Observations with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) have revealed ...

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

SN2021yfj is a new kind of supernova, challenging our understanding of stellar evolution. Its progenitor lost its outer shells well before the supernova happened and only consisted of its ...
