Searching for the supernova neutrino background to the universe

It's a sobering statement that stars like the sun, more accurately all stars will die eventually—yes, even the sun. Don't panic, though, we still have a good few billion years to go so you will get to the end of this article. ...

Deep learning speeds up galactic calculations

Supernovae, or exploding stars, play a critical role in the formation and evolution of galaxies. However, key aspects of these phenomena are notoriously difficult to simulate accurately in reasonably short amounts of time.

JWST looks at the debris disk around a white dwarf

Debris disks are quite common in the universe. Young stars have protoplanetary disks from which planets form. Black holes have accretion disks that are the source of the galactic jets. Supernova remnants can form a disk around ...

Quenched galaxies in the early universe

Recently, much attention has been given to massive, active galaxies discovered by the JWST in the early universe. But in contrast to these active galaxies, some galaxies that the JWST has discovered have been unusually quiet ...

Astrophysicists determine how to find a supernova

The probability of detecting a supernova associated with a gamma-ray burst is currently 0.00346%. A network of several telescopes in different geographical coordinates, checking data in different photometric filters, analyzing ...

Hubble finds bizarre explosion in unexpected place

A very rare, strange burst of extraordinarily bright light in the universe just got even stranger—thanks to the eagle-eye of the NASA/ESA Hubble Space Telescope. The phenomenon, called a Luminous Fast Blue Optical Transient ...
