fast radio burst

what is an FRB? Or fast radio burst

The first FRB was discovered in 2007, since when scientists have been working towards finding the source of their origin. 


Essentially, FRBs are bright bursts of radio waves (radio waves can be produced by astronomical objects with changing magnetic fields) whose durations lie in the millisecond-scale, because of which it is difficult to detect them and determine their position in the sky.

In other hand -

Fast radio bursts are extremely bright radio pulses from distant galaxies that last for only a few milliseconds.

 over a thousand have been found so far, researchers still don't know what kind of astronomical objects can produce so much energy in so little time.
