Hawking’s alien search catches mystery signals

- ADITI KHANNA

LONDON: A mission to explore intelligen­t alien life in the universe has recorded some mysterious signals coming from a galaxy 3 billion light years away, according to an Indian-origin scientist working on the ambitious project co-founded by Stephen Hawking. Vishal Gajjar is part of the team working under the Breakthrou­gh Listen project — set up by Hawking, one of the world's bestknown scientists, and Russian billionair­e Yuri Milner to discover the truth about the universe.

The latest fast radio bursts (FRBS) prove their equipment is working well and ready to pick up signs of life if they exist. “We really have no idea about where they come from,” Gajjar, one of the scientists from the University of California Berkeley Research Centre, told The Daily Telegraph.

He noted: “If some form of life would like to produce a signal that is detectable to another civilisati­on this could be a way to do it, but I don't think they are coming from intelligen­t civilisati­ons. “There are more theories than the number of sources. We have opened more questions than answers. As we do more study we find more weird things,” he said.

Breakthrou­gh Listen is a $100-million global astronomic­al initiative launched in 2015 by Hawking and Miller and has teams around the world using their telescopes to look for evidence of life. The initial 10-year programme will survey the 1,000,000 closest stars to Earth, scanning the entire galactic plane of the Milky Way.

Beyond our galaxy it will listen for messages from the 100 closest galaxies at 10 billion different frequencie­s. Announcing the project at the time at a press conference in London, Hawking said it was time to commit to finding the answer to life beyond Earth.

“Somewhere in the universe intelligen­t life may be watching the lights of ours aware of what they mean,” he said. Explanatio­ns for the latest signals detected range from rotating neutron stars with extremely magnetic fields, to energy sources used by extraterre­strial civilisati­ons to power spacecraft.

Whatever they are they left their galaxy when our Solar System was just two billion years old and life was just getting going on Earth. At first scientists thought the signals were the fallout from a catastroph­ic event in space, like a supernova, but then they repeated again in 2015 and 2016 suggesting the whatever object produced them was still there.
