After decades of debate, James Webb Space Telescope observations provide firm evidence of a neutron star inside the 1987A supernova remnant.
New observations of a neutron star in the Milky Way's center shed light on what makes mysterious fast radio bursts.
A brilliant flash of blue light briefly outshined its host galaxy before fading away — but then it exploded again and again, shedding light on the nature of its source.
A highly energetic fast radio burst, which broke the distance record, provides a crucial test for theories of these events' origins.
An explosive flash of blue light briefly appeared in intergalactic space, thousands of light-years from the nearest galaxy.
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.
