A team of space scientists from several institutions in The Netherlands, two in the U.S. and one in Sweden, has found evidence of multiple microsecond-length fast radio bursts (FRBs) by analyzing data from the Green Bank ...
In radio astronomy, there are lots of natural radio signals to observe. The glow of hydrogen gas, the swirl of electrons along a magnetic field, or the pop-pop-pop of pulsars. These signals usually have a very natural character ...

A pair of astrophysicists, one with Princeton University, the other the University of Maryland, has developed a new theory to explain fast radio bursts (FRBs). In their paper published in the journal Physical Review Letters, ...
Using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST), astronomers from the Purple Mountain Observatory (PMO) in Nanjing, China, have observed a pulsar known as RRAT J1913+1330. Results of the observational ...
Researchers using a telescope owned and operated by CSIRO, Australia's national science agency, have detected a "fast radio burst" in a nearby galaxy that questions what we know about how the phenomena form.
