Astronomers have recently obtained 15 radio bursts from an unknown source in the universe, they do not rule out the possibility that it is of alien origin.
According to Iflscience, a space observation station under the Breakthrough Listen science program, which searches for signs of alien life, has detected 15 short but very powerful radio bursts from a mysterious source far from Earth. 2.4 billion light years.
Radio bursts lasting just a few milliseconds known as radio bursts (FRBs) are often associated with distant galaxies. The source with the number FRB 121102 is the only place where the repeating flashes are emitted. In fact, astronomers have detected more than 150 radio bursts since FRB 121102.

“The flashes from this source have never been seen at such high frequencies,” said Andrew Siemion, program director of Breakthrough Listen. The Breakthrough team’s discovery caught the attention of the astronomy community.
Various theories have been put forward to explain the phenomenon. One of the theories is that the signal comes from a spinning neutron star with a super strong magnetic field. Some scholars have even suggested that the flashes emitted by FRB 121102 may have originated from the giant transmitters that power spacecrafts flying through interstellar space.
“Radio flashes are too bright even for a short duration and originate from a long distance. We are not sure of any natural sources capable of generating them,” said researcher Avi Loeb of the Harvard-Smithsonia Center for Astrophysics. “The anthropogenic source hypothesis is worth considering and testing.”

The Breakthrough team observed the latest FRB flashes over a five-hour period on August 26, using the Green Bank telescope in West Virginia. They collected about 400 terabytes of data during the process and analyzed this trove of data for evidence of radio flashes.
“Whether or not the radio flashes are a sign of alien technology, Breakthrough Listen is helping to open new frontiers and accelerate our understanding of the surrounding universe,” said Siemon.
