Radio telescope picks up new frequency in space

Scientists Pick Up First Mysterious Radio Signal From Deep Space

"The event is clearly detected at frequencies as low as 580 MHz and represents the first detection of an FRB at radio frequencies below 700 MHz".

The pulse's fast, low frequency suggests that the blast was extremely bright and originated from an insanely powerful source somewhere in the cosmos.

On the other hand, there are occasional Fast Radio Bursts with tantalizingly unknown origins. The signal has now been branded by the name "FRB 180725A". Since that time, more than 30 FRBs have been recorded but researchers still don't know what causes these mysterious and powerful flashes of radio light.

According to the MailOnline, the emission was detected by the Canadian Hydrogen Intensity Mapping Experiment telescope, which has been operating for less than a year.

The latest mystery signal was detected by CHIME, a state-of-the-art radio telescope that looks like a skateboarder's half-pipe in the mountains of British Columbia.

The FRB detected now is called FRB 180725A and this one is unique because it had a frequency as low as 580 Mhz. Until now, no FRB below 700 MHz has been recorded.

Scientists can not yet identify the process which produces the short and sharp radio wave bursts, which means we can not rule out the possibility they were made by aliens.

The question that remains is uncovering where these signals have come from, with many possible theories being thrown into the mix. Most of the time, radio telescopes like this don't hear anything out of the ordinary, but every so often an unexplained signal finds its way through the noise, and that's exactly what happened on July 25th.

Researchers are not ruling out the possibility that these fast radio signals, which only last a few milliseconds, might be sent out by an advanced alien civilization residing in the depths of space.

"It could even be some other physical mechanism we don't yet understand". Scientists are still unsure of their origin source, arguing that FRBs may be emerging from some kind of "extreme" environment in space, but none have been able to definitively show where they're coming from.

'They could be caused by exploding stars, supernova, exotic stars like pulsars, magnetars, neutron stars or massive black holes at the centre of distant galaxies.
