Radio telescope picks up new frequency in space

The FRB detected now is called FRB 180725A and this one is unique because it had a frequency as low as 580 Mhz.

According to a statement released in The Astronomer's Telegram (a bulletin board of astronomical observations posted by accredited scientists), the mystery signal - named FRB 180725A after the year, month and day it was detected - transmitted in frequencies as low as 580 megahertz, almost 200 MHz lower than any other FRBs ever detected.

A new bulletin from The Astronomer's Telegram reveals that the new telescope detected what is known as a Fast Radio Burst, or FRB.

A new telescope called the Canadian Hydrogen Intensity Mapping Experiment (CHIME) picked up the emission, which also has the lowest frequency of any burst recorded by our species.

This allowed the scientists to assume that the signal source with the code name "FRB 180725A" was extremely powerful.

The post reads: "During its ongoing commissioning, CHIME/FRM detected FRB 180725A on 2018 July 25 at 17:59:43.115 UTC (18:59:43.15 BST/13:59:43.15 ET)". As it later turned out, the unusual radio signal was just the first in a completely new wave of low-frequency FRBs detected by CHIME in the days to follow.

"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 FRB has ever been detected below 700 Mhz before.

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. Christopher Conselice, a professor of astrophysics at the University of Nottingham told Daily Mail, this discovery could help to pave the way for a greater understanding of what causes FRBs.

Unfortunately, we'll have to wait a long time before we know for sure if these sounds come from black holes colliding, exploding stars or aliens lurking in space.

Boyle added that an "artificial origin" of the signals is a possible source.

'It could even be some other physical mechanism that we don't yet understand'.
