Scientists have caught a odd signal from deep space

Researchers at CHIME radio telescope have reported recording a mysterious radio signal on July 25.

Puzzling pulses like these are sometimes called fast radio bursts (FRBs), because they may last just a few milliseconds. In a diagram measuring the radio frequency over time, there is a clear bright streak beginning below 600 MHz.

The latest FRB, which was detected by researchers at the Canadian Hydrogen Intensity Mapping Experiment in British Columbia, was allegedly the first to be heard between the much deeper frequency range of 400 to 800 MHz, rendering it a much lower signal than numerous FRB episodes before it. Usually, this radio telescope, as well as the other ones, doesn't detect anything interesting.

Helpfully, Dr Mark Halpern, of the University of British Columbia explained: "With the CHIME telescope we will measure the expansion history of the universe and we expect to further our understanding of the mysterious dark energy that drives the expansion ever faster".

"Additional FRBs have been found since FRB 180725A and some have flux at frequencies as low as 400 MHz".

The question that remains is uncovering where these signals have come from, with many possible theories being thrown into the mix.

Known as FRBs (or Fast Radio Bursts), the signals arrive with great force but last only a short amount of time, according to a report from The Independent highlighting the discovery.

This FRB is called 180725A, and what makes it so special is its low frequency - 580 Mhz, considering that scientists haven't detected any FBR under 700 Mhz until now. "These events have occurred during both the day and night and their arrival times are not correlated with known on-site activities or other known sources of terrestrial RFI [radio-frequency interference]". No one knows where they originate from or what they are exactly.

In any case - whether the merger of black holes, exploding stars or just noisy alien party - we will need a remarkable patience, while science can give a precise answer about where are these fast radio bursts.

FRBs detected by astronomers on Earth come from highly long distances and they're located so far off in space that we're not even able to see what's creating them.

Although FRBs are radio signals, astronomers and researchers can not tap into their information, making them quite mysterious.
