The new image isn’t just stunning—it may also provide clues about how this star survived its own explosion.
Astronomers using the James Webb Space Telescope have identified one of the most distant exploding stars ever confirmed. The supernova, SN 2023aeaf, was found at a redshift of 3.19...
When a supernova exploded in 1181, Chinese and Japanese sky-watchers recorded it. They couldn't have known what the object was, and why it appeared for six months then disappeared....
With roughly ten times as many gas filaments now resolved, the supernova remnant Pa 30 could guide searches for other stellar explosions that left surviving stars. A star survived...
Scientists using the Gemini North telescope in Hawai'i captured a new photo of Pa 30, a supernova remnant believed to be the remains of a supernova that people witnessed in August...
30 years ago, an amateur astronomer noticed a white dwarf star suddenly getting brighter. New research shows this is due to a Very Late Thermal Pulse, a type of helium flash. The s...
Astrophysicists think that hypernovae are the most powerful stellar explosions in the Universe. They're the most explosive type of core-collapse supernova. But the evidence for the...
A distant star has captured astronomers' attention over the past decade, teasing them with indications that it will soon explode as a supernova. But new research shows that somethi...
Nearly 3,000 exploding stars have revealed a startling possibility: the mysterious force accelerating the universe may be changing over time. The largest catalog of Type Ia superno...
As a star nears the end of its life, it faces two very different fates: It can explode as a supernova, leaving behind a neutron star, or collapse and become a black hole. What dete...
The most comprehensive catalogue of exploding white dwarf stars ever assembled has revealed new clues about dark energy, the mysterious force driving the universe’s accelerating ex...
When a star reaches its final stages of life, it ends in a bright, powerful explosion called a supernova and scatters material across the universe. A new study led by a University...
The most comprehensive catalogue of exploding white dwarf stars ever assembled has revealed new clues about dark energy, the mysterious force driving the universe’s accelerating ex...
The only known supernova remnant of its kind in the Milky Way has an unexpectedly intricate structure: chains of gas knots resembling pearls on a string, each wide enough to fit th...
Nova, who was feeble and only a few weeks old when she arrived at ARK, has thrived since her recovery and has a confidence in people that makes her a delight to be around.
The fate of a dying massive star may depend on more than its mass and internal structure. A massive star does not always go out in a brilliant supernova. Some instead collapse into...
The only known supernova remnant of its kind in the Milky Way has an unexpectedly intricate structure: chains of gas knots resembling pearls on a string, each wide enough to fit th...
Astronomers observe faint light signals from stellar objects, study it intently, and try to understand what's behind these signals. In one case, the signals they detected masquerad...
Learn about the remnant of a historic supernova observed around 850 years ago and the zombie star that has survived at its center.
A new image of the Helix Nebula reveals how dying stars return material to the galaxy. The Helix Nebula offers a rare look at what happens after a dying star releases its outer lay...
The James Webb Space Telescope (JWST) has detected a possible supernova in the early universe just days after the star exploded. Called AT 2026abck, the transient lies in a star-fo...
Identity-fluid particles may carry some energy out, leading to direct collapse.
The most comprehensive catalog of exploding white dwarf stars ever assembled has revealed new clues about dark energy, the mysterious force driving the universe's accelerating expa...
A model of lunar soil mixing could help scientists reconstruct millions of years of supernova debris preserved on the Moon. When massive stars die, some end in supernova explosions...
