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.
New Observations Add Fuel to Fast Radio Burst Origin Debate
A peculiar repeating fast radio burst seems to be coming from a dynamic environment in an otherwise uninteresting region, leaving researchers scratching their heads as to the burst’s origin.
Radio “Heartbeat” Teases Fast Radio Burst Origins
Scientists have observed pulses from a fast radio burst, suggesting the flash might have come from a neutron star.
An Unusual Source Deepens Fast Radio Burst Mysteries
A new source of fast radio bursts raises questions about how much we really know about these mysterious flares.
A Possible Optical Counterpart to a Fast Radio Burst?
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.
Fast Radio Burst's Unlikely Home Puzzles Astronomers
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.
Exploring a Magnetospheric Origin for Fast Radio Bursts
Astronomers are starting to close in on the origins of fast radio bursts — powerful, fleeting flashes of radio waves seen at extragalactic distances.
