The largest haul of fast radio burst observations ever recorded, all from a single fast radio burst, is helping astronomers understand what causes these fleeting cosmic phenomena
What seemed a lucky break — the discovery of a gamma-ray burst in the most distant known galaxy — might instead be the flash of passing space debris. As satellites fill low-Earth orbit, such events might become common.
Some 10 million years ago, dying stars cleared a giant cavity in space and ultimately inspired a new generation of star formation.
Astronomers have found the first circumstantial evidence for a supernova triggered by a merger with a neutron star or maybe even a black hole.
This week in astronomy news, we learn that some white dwarfs still burn and image X-rays from black holes almost 12 billion light-years away.
This week in astronomy news: A citizen scientist happens upon a weird, ancient brown dwarf and astronomers discover that Sun-like stars eat their own planets.
Strange behavior caught by two radio observatories may send theorists back to the drawing board.
The CHIME telescope has released its first catalog with 492 unique sources of fast radio bursts, the brief flashes of radio waves that have been intriguing astronomers over the past decade.
The Crab Nebula pulsar has sporadically bursted for decades. Now, astronomers have found these mysterious bursts release even more energy than thought.
