Mysterious Radio Signals from Space Detected


Astronomers detected an intense radio burst that hit Earth, the strange thing being that they don’t know where it came from. This one is really low (approximately 580 megahertz), about 200 MHz lower than what we were able to previously detect.

What was it?

This one is called a fast radio burst and this type is characterized by explosiveness and mystery as they happen all around the Universe. In an extremely quick time, we are talking about milliseconds, these radio bursts are able of generating as much energy as 500 million suns.

After repeated scenarios where fast radio bursts hit our planet, scientists managed to detect signals that came from the same location. That’s how they were able to find out the exact place where these radio waves were coming from.

What happened, exactly?

The Astronomer’s Telegram features a report which states as follows: on July 25th 2018, the radio telescopes found in Canada’s British Columbia were able to detect a curious fast radio burst. The astronomers that encountered it named it FRB 180725A (after the year, month and date of its detection).

The curious thing about this radio burst is its low frequency, of 580 MHz, being the lowest recorded under 700 MHz. Scientists were able to use the data to pinpoint the source. The signals came from far away, billions of light-years away. They think that whatever object emitted such radio bursts is extremely energetic.

What does the future hold for us?

Well, astronomers are hopeful that this new detection will help them uncover the mysteries of the Universe like the origin or the Epoch of Reionisation. Since FRB 180725A, other fast radio bursts were detected, having frequencies as low as 400 MHz. This kind of event can occur during day or night and they don’t have a standard arrival time.
