Fast radio burst - Wikipedia
In radio astronomy, a fast radio burst (FRB) is a transient radio pulse of length ranging from a fraction of a millisecond, for an ultra-fast radio burst, [2][3] to 3 seconds, [4] caused by some high-energy astrophysical process not yet understood.
Mysterious fast radio bursts may have diverse origins in space
6 days ago · Astronomers have traced two mysterious fast radio bursts from space to wildly different places, which suggests the phenomenon may originate in diverse ways.
Flashes from ancient galaxy deepen mystery of fast radio bursts
1 day ago · Astronomers have traced the origin of a fast radio burst (FRB) to the edge of an ancient galaxy — suggesting that these mysterious, millisecond-long flashes of energy are even weirder than ...
First fast radio burst traced to old, dead, elliptical galaxy
Jan 21, 2025 · For the first time, astronomers have traced a fast radio burst (FRB) to the outskirts of an ancient, dead, elliptical galaxy — an unprecedented home for a phenomenon previously associated with much younger galaxies.
MIT scientists pin down the origins of a fast radio burst
Jan 1, 2025 · MIT astronomers pinned down the origins of at least one fast radio burst, a brief and brilliant explosion of radio waves emitted by an extremely compact object. The team’s novel technique might also reveal the sources of other FRBs.
Hubble Finds Weird Home of Farthest Fast Radio Burst - Science@NASA
Jan 9, 2024 · Astronomers using NASA’s Hubble Space Telescope have found a rare event in an oddball place. It’s called a fast radio burst (FRB), a fleeting blast of energy that can – for a few milliseconds – outshine an entire galaxy. Hundreds of FRBs have been detected over the …
MIT scientists pin down the origins of a fast radio burst
Jan 1, 2025 · Fast radio bursts are brief and brilliant explosions of radio waves emitted by extremely compact objects such as neutron stars and possibly black holes. These fleeting fireworks last for just a thousandth of a second and can carry an enormous amount of energy — enough to briefly outshine entire galaxies.
