Fast Radio Burst
Researchers say they have detected a fast radio burst, or FRB, originating from a dwarf galaxy located nearly 3 billion light-years from Earth. It seems it is a "newborn".

What's behind it?
Astronomers suspect that FRBs may be unleashed by some extreme objects: like say, a neutron star or a supernova or a magnetar, which is a type of neutron star with an ultra-strong magnetic field.

Faster than the blink of an eye
The burst blinks on and off in about a millisecond. That's faster than the blink of an eye. Most blink once, a few emit multiple bursts.

Found in 2019
The FRB was first spotted in 2019 using the FAST telescope in China's Guizhou province, the world's largest single-dish radio telescope.
