First low-frequency fast radio burst to grace our skies detected at last

First low-frequency fast radio burst to grace our skies detected at last

They are burst of radio emissions that last milliseconds and have been first discovered about ten years ago. Until now, no FRB below 700 MHz has been recorded.

This puzzling radio signal, dubbed as FRB 180725A is the lowest radio burst ever detected from beyond our galaxy, the Milky Way, and, as the experts agree, its source must be a very powerful one.

The new Canadian Hydrogen Intensity Mapping Experiment (CHIME) telescope, located in British Columbia, Canada, has the objective of scanning the space for radio signals and listening to them.

Though it has been in operation for only about a year, CHIME has already detected several noteworthy FRBs, including several more low-frequency signals that followed shortly after the noteworthy FRB 180725A last week.

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)". Studying the peculiar signal could give astronomers better clues as to how these extragalactic radio waves form and where they're coming from. It was specifically designed with the low and deep 400 to 800 frequencies in mind. In a diagram measuring the radio frequency over time, there is a clear bright streak beginning below 600 MHz. "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]".


Christopher Conselice, professor of astrophysics at Nottingham University, told Mail Online: "We don't know their origin, they could be caused by a number of things".

The mysterious radio burst from deep space is tricky and the origin can not be explained.

Whatever it is - black holes colliding, a star exploding, or just some aliens having a really loud party - we'll probably have to wait a long, long time before science can say for certain.

Scientists also believe that whatever produced the signal tends to be an extremely powerful extraterrestrial being.

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.
