What's up in
After a burst lit up their telescope “like a Christmas tree,” astronomers were able to finally track down the source of these cosmic oddities.
Brief cosmic blips called fast radio bursts have puzzled astronomers since their discovery earlier this decade. Now researchers appear to be close to understanding what powers them.
A mysterious object that repeatedly bursts with ultra-powerful radio waves must live in an extreme environment — something like the one around a supermassive black hole.
Repeating radio bursts are among the most mysterious phenomena in the universe. A new theory explores how some of their puzzling properties can be explained by galactic lenses made of plasma.
