Sinister cosmic object explodes hundreds of times a day and baffles scientists

Astronomers have been left scratching their heads after discovering a 'mysterious' object in space that keeps exploding.

The unusual cosmic presence, which is located in a dwarf galaxy roughly 3 billion light-years away from Earth, is estimated to have shot out about 1,652 blasts of energy over a period of just 60 hours.

It is currently being described as 'fast radio burst' (FRB), a rare phenomenon that was only observed for the first time in 2007, and was picked up by space scientists using the 500 metre-wide Aperture Spherical radio Telescope (FAST) in China.

FRBs give off huge pulses on the electromagnetic spectrum, which last only a few thousandths of a second, but in that time produces as much energy as the sun does in an entire year.

Live Science reports that when the team first began studying the FRB, they were merely collecting data on this one section of space, before they began to notice what was occurring was highly unusual.

Bing Zhang, an astrophysicist at the University of Nevada, Las Vegas, told the website: “Initially, it was just stamp collecting.”

What creates this kind of FRB is still unknown, and there are some exciting theories on what could be behind the energy bursts.

Some believe they are a variation on black holes, while others have suggested that they are 'cosmic strings' that date all the way back to the Big Bang.

But perhaps the most explosive explanation of all is that they could be transmissions from far-off alien lifeforms.

In 2019, the discovery of a FRB inside of our own galaxy for the first time led scientists to entertain the possibility that these bursts of energy could be manufactured, rather than randomly occurring - although boffins say there is not enough evidence to support this yet.

Professor Avi Loeb said: “Fast radio bursts are exceedingly bright given their short duration and origin at great distances, and we haven’t identified a possible natural source with any confidence”

“An artificial origin is worth contemplating and checking.“
