The Big Breakthrough Listen

If you were a Russian billionaire with money to burn and a penchant for astronomy and physics what would you do? Well, rather than spend it on a 1,000 ft long super-yacht, you might want to spend it on the search for extraterrestrial intelligence. That’s what Yuri Milner is doing. So, hats off to him and his colleagues.

Though, I do hope any far-distant aliens have similar, or greater, sums of cash to throw at equipment to transmit a signal so that we may receive it. Also, I have to wonder what alien oligarchs spend their excess millions and billions on — and what type of monetary system they use (hopefully not Euros).

From the Guardian:

Astronomers are to embark on the most intensive search for alien life yet by listening out for potential radio signals coming from advanced civilisations far beyond the solar system.

Leading researchers have secured time on two of the world’s most powerful telescopes in the US and Australia to scan the Milky Way and neighbouring galaxies for radio emissions that betray the existence of life elsewhere. The search will be 50 times more sensitive, and cover 10 times more sky, than previous hunts for alien life.

The Green Bank Observatory in West Virginia, the largest steerable telescope on the planet, and the Parkes Observatory in New South Wales, are contracted to lead the unprecedented search that will start in January 2016. In tandem, the Lick Observatory in California will perform the most comprehensive search for optical laser transmissions beamed from other planets.

Operators have signed agreements that hand the scientists thousands of hours of telescope time per year to eavesdrop on planets that orbit the million stars closest to Earth and the 100 nearest galaxies. The telescopes will scan the centre of the Milky Way and the entire length of the galactic plane.

Launched on Monday at the Royal Society in London, with the Cambridge cosmologist Stephen Hawking, the Breakthrough Listen project has some of the world’s leading experts at the helm. Among them are Lord Martin Rees, the astronomer royal, Geoff Marcy, who has discovered more planets beyond the solar system than anyone, and the veteran US astronomer Frank Drake, a pioneer in the search for extraterrestrial intelligence (Seti).

Stephen Hawking said the effort was “critically important” and raised hopes for answering the question of whether humanity has company in the universe. “It’s time to commit to finding the answer, to search for life beyond Earth,” he said. “Mankind has a deep need to explore, to learn, to know. We also happen to be sociable creatures. It is important for us to know if we are alone in the dark.”

The project will not broadcast signals into space, because scientists on the project believe humans have more to gain from simply listening out for others. Hawking, however, warned against shouting into the cosmos, because some advanced alien civilisations might possess the same violent, aggressive and genocidal traits found among humans.

“A civilisation reading one of our messages could be billions of years ahead of us. If so they will be vastly more powerful and may not see us as any more valuable than we see bacteria,” he said.

The alien hunters are the latest scientists to benefit from the hefty bank balance of Yuri Milner, a Russian internet billionaire, who quit a PhD in physics to make his fortune. In the past five years, Milner has handed out prizes worth tens of millions of dollars to physicists, biologists and mathematicians, to raise the public profile of scientists. He is the sole funder of the $100m Breakthrough Listen project.

“It is our responsibility as human beings to use the best equipment we have to try to answer one of the biggest questions: are we alone?” Milner told the Guardian. “We cannot afford not to do this.”

Milner was named after Yuri Gagarin, who became the first person to fly in space in 1961, the year he was born.

The Green Bank and Parkes observatories are sensitive enough to pick up radio signals as strong as common aircraft radar from planets around the nearest 1,000 stars. Civilisations as far away as the centre of the Milky Way could be detected if they emit radio signals more than 10 times the power of the Arecibo planetary radar on Earth. The Lick Observatory can pick up laser signals as weak as 100W from nearby stars 25tn miles away.
