Astronomers have found a star that has a magnetic field rivaling the strongest magnet humans have ever built — and it might explain the origin of highly magnetic cinders known as magnetars.
This week, James Webb Space Telescope reveals new details in the Ring Nebula and shows that the most distant known star isn't alone. Meanwhile, patient astronomers have collected 17 years' worth of images of the super-Jupiter Beta Pictoris b.
Images capture the birth of stars and planets in multiple results from space- and ground-based telescopes.
New research proposes a way for fast radio bursts to escape the confines of a magnetized star and jet out into space — by getting help from theoretical particles called axions.
Deep-sky objects may appear static throughout our lifetime but by carefully "blinking" archival and current images we can discern real changes in their appearance.
Supermassive stars might explain the unusual amounts of nitrogen in one of the most distant known galaxies, GN-z11.
Massive, dying stars — behemoths tens of times the Sun's mass — should emit gravitational waves that we can hear with LIGO.
The first stars are too faint and far away to detect directly, but their gaseous remains can be seen absorbing the light of distant galaxies.
Flashes of radio waves — whose exact sources are still a bit of a mystery — are helping astronomers learn about the hot gas that surrounds the Milky Way.
Gamma-ray bursts are the most luminous explosions in the universe, and we’ve learned much about these superlative outbursts since their discovery in 1967.
