Fast radio bursts are the short, intense flashes of radio waves that are thought to be the product of small, distant, extremely dense objects, though exactly what those objects might be is a longstanding mystery in astrophysics.
FRBs typically last a few milliseconds, during which time they can outshine entire galaxies. Since the first FRB was observed in 2007.
Astronomers have catalogued over 100 fast radio bursts from distant sources scattered across the universe, outside our own galaxy.
The astronomers observed that this 16-day pattern of fast radio bursts reoccurred consistently across more than 500 days of observations.
