Indian American scientist may have discovered extraterrestrial activity through Breakthrough Listen


NEW YORK – An Indian American scientist, Vishal Gajjar, a UC Berkeley Postdoctoral Researcher, who was looking for extraterrestrials through a $100 million Breakthrough Listen project, has detected 15 radio bursts coming from a dwarf galaxy about three million light years away from earth during his five-hour-long observation.

“In the early hours of Saturday (August 26), UC Berkeley Postdoctoral Researcher Dr. Vishal Gajjar observed the location of FRB 121102 using the Breakthrough Listen backend instrument at the Green Bank Telescope in West Virginia. The instrument accumulated 400 TB of data on the object over a five hour observation, observing the entire 4 to 8 GHz frequency band,” Breakthrough Listen said in a statement, shared with Times of India.

Analysis by Gajjar and the Listen team revealed 15 new pulses from FRB 121102 and also confirmed that the source is in a newly active state and is being speculated as energy source used by extra-terrestrial civilizations to power spacecraft.

“Further, the high resolution of the data obtained by the Listen instrument will allow measurement of the properties of these mysterious bursts at a higher precision than ever possible before,” the statement continued, adding that the observations showed that for the first time FRBs emitted at higher frequencies with the brightest emission occurring at around 7 GHz, than what was previously observed.

“When the 15 fast radio bursts (FRB) left their host galaxy, our entire Solar System was just 2 billion years old. Life on Earth consisted of only single-celled organisms, and it would be another billion years before even the simplest multi-cellular life began to evolve,” the statement further said.

Fast radio bursts, or FRBs, are brief, bright pulses of radio emission from distant galaxies and they were first detected with the Parkes Telescope in Australia and have now been seen by several radio telescopes around the world.

“FRB 121102 was discovered on November 2, 2012, which gives it the name (121102). In 2015, it was the first FRB seen to repeat, ruling out theories of the bursts’ origins that involved the catastrophic destruction of the progenitor (at least in this particular instance),” the statement said.

According to the Times of India report, in 2016, the repeater was the first FRB to have its location pinpointed with sufficient precision to allow its host galaxy to be identified, residing in a dwarf galaxy about three billion light years away from Earth.

Since then, attempts to understand the mechanism that generates FRBs have made the dwarf galaxy a target of almost all ongoing monitoring campaigns across the world.

Breakthrough Listen, a global astronomical initiative launched in 2015 by Internet investor and philanthropist Yuri Milner and cosmologist Stephen Hawking, is also observing nearby stars and galaxies for signatures of extraterrestrial technology and the Listen science team at UC Berkeley has added FRB 121102 to its list of targets.

Breakthrough claims that whether or not FRBs eventually turn out to be signatures of extraterrestrial technology, the project is helping push the frontiers of a new and rapidly growing area of our understanding of the Universe.
