NASA spacecraft begins search for new planets

Technology
NASA's Tess spacecraft has blasted off from Earth in a search for new planets that could support life.Tess lifted off from Cape Canaveral in Florida on Wednesday evening local time, riding a SpaceX Falcon rocket.The Transiting Exoplanet Survey Satellite will spend two years scouring 85% of the sky and hundreds of thousands of its brightest stars.The satellite, about the size of a washing machine, will scan the stars for signs of periodic dimming, which may mean that planets are orbiting around them.It is hoped that Tess will find around 20,000 exoplanets - planets outside our solar system - with more than 50 expected to be Earth-sized.There are already 3,700 exoplanets that we know of, with another 4,500 on the not-yet-verified list.Tess is looking for the ones that are Earth-like and clos...

Barclays to kick off search for new chairman

Business
Barclays is preparing to kick off the hunt for a successor to chairman John McFarlane, paving the ‎way for the third change at the top of Britain's second-largest bank since 2012.Sky News has learnt that Crawford Gillies, Barclays' senior independent director, is expected to instruct headhunters shortly to conduct a wide s‎earch for its next chairman.Mr McFarlane is expected to step down at the bank's annual meeting next year, although the timetable remains fluid and could be extended, according to people close to the bank.Among the leading candidates to replace him will be Sir Gerry Grimstone, who has announced his intention to step down as Standard Life Aberdeen's chairman next year.Sir Gerry, who was appointed deputy chairman and senior independent director in 2016, recently relinquishe
Search for first stars yields proof of dark matter

Search for first stars yields proof of dark matter

Science
Feb. 28 (UPI) -- Astronomers say they've discovered evidence of dark matter. Scientists found the dark matter signatures while searching for the universe's first stars.According to a team of researchers from Tel Aviv University and Arizona State University, the newly discovered signal is the product of interactions between normal and dark matter -- the first of its kind.The signal hails from the distance universe, when the cosmos was still in its infancy -- 180 million years after the Big Bang."Dark matter is the key to unlocking the mystery of what the universe is made of," Rennan Barkana, head of the astrophysics department at Tel Aviv's School of Physics and Astronomy, said in a news release. "We know quite a bit about the chemical elements that make up the Earth, the sun and other star...
Crypto-currency craze 'hinders search for alien life'

Crypto-currency craze 'hinders search for alien life'

Science
Scientists listening out for broadcasts by extra-terrestrials are struggling to get the computer hardware they need, thanks to the crypto-currency mining craze, a radio-astronomer has said.Seti (Search for Extraterrestrial Intelligence) researchers want to expand operations at two observatories.However, they have found that key computer chips are in short supply."We'd like to use the latest GPUs [graphics processing units]... and we can't get 'em," said Dan Werthimer.Demand for GPUs has soared recently thanks to crypto-currency mining."That's limiting our search for extra-terrestrials, to try to answer the question, 'Are we alone? Is there anybody out there?'," Dr Werthimer told the BBC."This is a new problem, it's only happened on orders we've been trying to make in the last couple of mon...
Black box under desert may be key to alien search

Black box under desert may be key to alien search

Technology
A black box locked away in solitude beneath the world's driest desert in northern Chile could be vital in the search for alien life.The box is the most precise scientific instrument of its kind ever built; more than 10 times stronger than the most powerful spectrograph in operation today.Nicknamed "Espresso", it will be connected to a facility of four telescopes so massive they are collectively referred to simply as the Very Large Telescope (VLT), where it will scan the skies for planets beyond our solar system.In silence, buried beneath the facility on the Paranal mountain in the Atamaca desert, the black box will analyse the wobble in distant stars to see if that wobble was caused by an Earth-like planet orbiting it.Espresso, which stands for Echelle Spectrograph for Rocky Exoplanet and ...
