A new source of fast radio bursts raises questions about how much we really know about these mysterious flares.
Astronomers have spotted the X-ray flash that precedes a nova. The brief flare is the first sign of a white dwarf erupting into a nuclear-fusion fireball.
What’s the mechanism behind millisecond-duration bursts of radio energy coming from outer space? A team searched for visible-light counterparts to constrain the origin of fast radio bursts — and found one.
A recently discovered type of stellar explosion might fit right in among the spectrum from regular supernovae to massive gamma-ray bursts.
Astronomers have found a fast radio burst — presumably a flash from a young stellar remnant — amongst the ancient stars of a globular cluster, challenging ideas about what produces these enigmatic flashes.
Astronomers are starting to close in on the origins of fast radio bursts — powerful, fleeting flashes of radio waves seen at extragalactic distances.
Astronomers have identified the origin of a mysterious flash that occurred three years ago.
Astronomers might have spotted a stellar-mass black hole in another galaxy — but not everyone agrees with what they found.
