In all the researchers spotted some 13 of the bursts in just a three week period, offering a vast new trove of data for the scientists hunting for their source.
A fast radio burst lasts only a few milliseconds; due to both the very brief appearance and the inability to predict where they will happen, it has proven very hard for astronomers to study the FRBs. Knowing that there is another suggests that there could be more out there.
A newly published study reveals that scientists have detected a second source of these repeat fast radio bursts, as well as multiple FRBs from different locations.
"Knowing that there is another suggests that there could be more out there", said Ingrid Stairs, a member of the CHIME team and an astrophysicist at the University of British Columbia.
But now, using the Canadian Hydrogen Intensity Mapping Experiment (CHIME) instrument, researchers have detected a second such repeating event.More news: Lenovo reveals its 'smartest ever' AI-driven Yoga laptops
The repeating FRBs were detected during CHIME's trial run earlier this summer, which used only a small amount of the telescope's potential power.
"And with more repeaters and more sources available for study, we may be able to understand these cosmic puzzles - where they're from and what causes them".
FRBs are thought to emanate from sources billions of light years away outside our galaxy, the Milky Way.
FRBs are not rare, as about 60 have been catalogued since 2007, but only one has been a repeating FRB so far, opening up debate as to what causes them.
Before CHIME began to gather data, some scientists wondered if the range of radio frequencies the telescope had been created to detect would be too low to pick up fast radio bursts.More news: AMD's 7nm Radeon Vega VII takes aim at Nvidia's RTX 2080
Tom Landecker, a CHIME team member from the National Research Council, said the findings provide rich information about the sources and environments that generate fast radio bursts.

The telescope at the Canadian observatory that found the latest signals had previously detected the lowest frequency FRB known on record at wavelengths of 400 megahertz, according to Nature. "But it has to be in some special place to give us all the scattering that we see".
The precise nature and origin of the blasts of radio waves is unknown. "We haven't solved the problem, but it's several more pieces in the puzzle". "There are some models where intrinsically the source can't produce anything below a certain frequency", team member Arun Naidu of McGill University said in a statement.
Stairs said that with CHIME, "mapping the entire northern hemisphere every day, we're bound to find more repeaters over time".More news: Lady Gaga wins second Golden Globe award in her career
Experts have debated whether black holes or super-dense neutron stars are responsible, but others have suggested more outlandish theories.
