The telescope detected a Fast Radio Burst, or FRB, which is unique because the origins are completely unknown.
As a result, scientists believe that the source (whatever it is - PRESUMABLY ALIENS, THOUGH) is likely to be extremely powerful. The signal has now been branded by the name "FRB 180725A".
Fast radio bursts are extremely unusual, with the first discovered in 2007 and only two dozen recorded since then. Until now, no FRB below 700 MHz has been recorded.
Dubbed the FRB 180725A, it only lasted a couple of milliseconds and was caught by the year-old Canadian Hydrogen Intensity Mapping Experiment or CHIME.
For example, FRB 121102 was detected repeatedly over several years.
"Additional FRBs have been found since FRB 180725A and some have flux at frequencies as low as 400 MHz".More news: Worst Weekend For Tiger Woods at Firestone Since 2010 — Tiger Tracker Postscript

This unprecedented discovery was presented yesterday in the journal Astronomer's Telegram by Patrick Boyle of McGill University in Montreal, Canada, who elaborated on the characteristics of the other radio signals.
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. Most of the radio signals received by CHIME come from our Milky Way galaxy. Not much is known about these short, high-energy signals, except that they have been attributed to a number of different potential sources, one more exotic than the other.
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.
In an interview with the Daily Mail, astrophysics professor Christopher Conselice of the University of Nottingham in the United Kingdom discusses the possible sources of FRBs, noting that the recently-discovered low-frequency signals might shed new light into what causes this intriguing phenomenon. FRBs may even reach our planet thousands of times a day, Conselice said; we just haven't built enough tools to detect them all yet.
Mysterious radio signals emitted from across the universe. 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.
