In the process of trying to observe FRB-121102 Astronomers ended up overcoming with the new bursts.
Backed by Mark Zuckerberg, Stephen Hawking, and the billionaire entrepreneur Yuri Milner, The Breakthrough Listen initiative was able to record these unusual signals thanks to the Green Bank Telescope, in West Virginia, the Parkes Radio Telescope in Australia, and the Automated Planet Finder of the Lick Observatory, in Mt Hamilton, California.
Scholz, who was not involved with the new discovery, was with McGill University when he and a team of astronomers discovered FRB 121102 to be a repeater. Researchers conducted five hours long observation campaign, during which they succeed observing the new bursts coming from the 3 billion light years away galaxy.
The Berkeley Astronomers Telegram reports that the source of these latest bursts, called FRB 121102, is the first to produce repeating FRBs, and this most recent batch of 15 pulses is further reaffirming its repeating nature, strongly ruling out a catastrophic source, such as a supernova explosion.
In 2012, a FRB named 121102 was observed for the first time.
While looking for signs of intelligent life in the universe, astronomers have detected 15 fast radio bursts from a distant galaxy. Normally, FRBs fire off once and aren't heard from again, but one outlier has been particularly chatty over the years.
The observations also show for the first time that FRBs emit at higher frequencies (with the brightest emission occurring at around 7 GHz) than previously observed.

The researchers are unsure whether the signals from the dwarf galaxy were sent before or after life came into existence on earth. 400 Terabytes of data over the 4 to 8 Hz frequency band was collected which is mostly used for satellite communications transmissions. "It should be noted that they can still be valid for other FRBs". Soon after the radio bursts were detected, there are talks that these bursts may be coming from an alien spaceship.
Late past year, global researchers, including those from McGill University, discovered that the same source was emitting Fast Radio Bursts (FRBs) from a dwarf galaxy three-billion light-years away.
"Fast radio bursts are exceedingly bright given their short duration and origin at great distances, and we haven't identified a possible natural source with any confidence", said Avi Loeb of the Harvard-Smithsonian Center for Astrophysics who examined the feasibility of building such a device in a paper published earlier this year. At that time, earth was home to only single-celled organisms. "While it would be unwise to exclude the possibility that there are is other intelligent, technologically-capable, life in our universe, it is also unwise to immediately ascribe any new and poorly-understood astronomical phenomena to the work of alien life".
