Supernova

Models of the universe predict that supernova remnants should be far more common than they are. Now, a new image from sensitive radio telescopes reveal that the missing remnants are hiding in plain sight.

Tree rings can preserve a snapshot of the Earth throughout the tree's life. Now Australian scientists analyzing these records have found evidence of huge radiation storms that periodically bathe the planet – and their origin remains a mystery.

NASA has released a huge new report that astronomers are calling Hubble’s magnum opus. Analyzing 30 years of data from the famous space telescope, the new study makes the most precise measurement yet of how fast the universe is expanding.

Astronomers have discovered a strange intergalactic ring that may be the first of its kind found. The large radio circle lurks between the Milky Way and a neighboring galaxy, and its discoverers suggest it may be the remains of an unusual supernova.

Astronomers have discovered a big hole in space. New 3D visualizations of the Perseus and Taurus star-forming clouds have revealed a large cavity between them, possibly created in ancient supernova explosions.

Astronomers have spotted a new type of supernova for the first time. An unlucky star seems to have prematurely exploded after colliding with an extremely dense object, perhaps a black hole or a neutron star, creating a unique signature in the sky.

Supernovae usually appear suddenly in the sky, but now astronomers have spotted one in advance. The telltale sign is a star with a “teardrop” shape, as it gets stretched out by the gravitational pull of a companion.

A bizarre star may have its origins in an extremely energetic event. Astronomers have found that a star with an unusual composition may have formed in the wake of a new type of hypernova – a stellar explosion with 10 times the energy of a supernova.

Astronomers have detected the highest-energy light ever seen. Hundreds of gamma rays were detected with ultra-high energies, with the most powerful signals crossing the Peta-electronvolt threshold – much higher than thought possible in our galaxy.

How exactly supermassive black holes got so big remains a mystery, but a new study suggests they may have been born from supernovae of hypothetical, primordial stars far bigger than any around today. And we might soon be able to detect the leftovers.

Astronomers have identified the remains of a rare type of supernova in our home galaxy for the first time. These events, known as Type Iax supernovae, occur when white dwarfs explode and may leave behind a “zombie star.”

A new NASA release has converted astronomy data into sounds, allowing the listener to hear musical compositions derived from the structure of the cosmos. The process takes data points in images such as galaxies or stars, and assigns them sounds.
