‘Technosignatures’ could help in search for alien life | Offbeat News

Published

Scientists are developing techniques to detect signatures from space in their search for alien life.

The Very Large Array (VLA) telescope, at the National Radio Astronomy Observatory (NARO) site in Socorro, New Mexico, will be used to constantly seek evidence of technosignatures.

A technosignature is a proxy for the existence of a technologically advanced, extraterrestrial civilisation, according to scientists at the Search for Extraterrestrial Intelligence (SETI) Institute in California.

These include things such as the chemical composition of a planet’s atmosphere, laser emissions or structures orbiting stars.

The VLA is a collection of 27 radio antennas – and one spare – which work together to effectively act as a single huge telescope.

Bill Diamond, president and chief executive of the SETI Institute, said: “Having access to the most sensitive radio telescope in the northern hemisphere for SETI observations is perhaps the most transformative opportunity yet in the history of SETI programmes.”

Dr Tony Beasley, director of the NRAO, based in the US state of Virginia, said: “Determining whether we are alone in the universe as technologically capable life is among the most compelling questions in science.”

He added: “As the VLA conducts its usual scientific observations, this new system will allow for an additional and important use for the data we’re already collecting.

“As continuing discoveries show us that planets are very common components of the universe, and we are able to study the characteristics of those planets, it’s exciting that at the same time, technological advances are giving us the tools to greatly expand our search for signs of life.

“We also look forward to the coming decade, when we hope to build a next-generation Very Large Array, which will be able to search a volume of the universe a thousand times larger than that accessible to current telescopes – making it the most powerful radio technosignature search machine humanity has ever constructed.”

The scientists are also making computer models to simulate extraterrestrial environments, helping the search for life beyond the solar system and planets that can support future searches for habitable planets and life beyond the solar system.

Victoria Meadows, principal investigator for Nasa’s virtual planetary laboratory at the University of Washington, said: “Upcoming telescopes in space and on the ground will have the capability to observe the atmospheres of Earth-sized planets orbiting nearby cool stars, so it’s important to understand how best to recognise signs of habitability and life on these planets.

“These computer models will help us determine whether an observed planet is more or less likely to support life.”

The new developments come after astronomers based in Canada detected radio signals from outer space that repeat at regular intervals.

The series of fast radio bursts (FRBs) – short-lived pulses of radio waves that come from across the universe – were detected about once an hour for four days and then stopped, only to start up again 12 days later.

FRBs are not in and of themselves unusual, but previous observations have shown them to be mostly emitted at random.

Brexit: UK and EU will ‘rip each other apart’ in talks, France predicts | Politics News

Published

on

Prime Minister Boris Johnson has been warned that he will face a tough battle with the European Union in his efforts to secure a trade deal in the aftermath of Brexit.

France’s foreign minister Jean-Yves le Drian gave the prediction during the Munich Security Conference, as both sides prepare to begin negotiations on the UK’s future relationship with the bloc.

Mr le Drian warned Mr Johnson that Brussels will defend its interests when talks formally open up next month, saying: “I think that on trade issues and the mechanism for future relations, which we are going to start on, we are going to rip each other apart.

“But that is part of negotiations, everyone will defend their own interests.”



BREXIT PARSONS







Now the UK is out of the EU, what next?

The UK’s chief negotiator David Frost is set to make it clear that Mr Johnson will walk away from talks with the EU, unless it drops what he calls its “ridiculous and unreasonable” demands.

Mr Frost is said to be travelling to Brussels on Monday to lay down his opening gambit, following a meeting of his 40-strong negotiating team last week.

Mr le Drian is a close ally of French President Emmanuel Macron, and is one of the latest major European voices to speak out about the tough road ahead for the UK.

Fishing will be high on the agenda during trade talks, and it is believed that Mr Macron wants EU fleets to keep their access to UK waters, in what is set to be a key demand in the negotiations.

However, Mr Johnson has said that the UK will take control of its fishing waters, acting as a “independent coastal state” once the Brexit transition period is over.

The EU has sent repeated warnings to the UK ahead of talks, saying it should not expect to be able to carry enjoying “high quality” market access if it demands on moving away from the bloc’s existing social and environmental standards.

The new European Commission president, Ursula von der Leyen, told the European Parliament this week that Mr Johnson would have to accept a “level playing field” on rules and standards.

Britons land in Sharm el Sheikh as 5-year flight restriction lifted | World News

Published

One of the first flights from the UK to Sharm el Sheikh has landed after restrictions on flying to the Egyptian resort were lifted.

British tourists on the TUI flight from Gatwick were greeted by celebrations, with fire engines jetting water over the top of the aircraft and a reception featuring flowers, music and cocktails.

Flights between the UK and Sharm el Sheikh were halted in November 2015 after a bomb blew up on a Russian airliner shortly after take-off from Sharm el Sheikh airport, killing all 224 people on board.

The Department for Transport lifted the restrictions in October, saying there had been “improvements in security procedures” and “close co-operation between our aviation security experts and their Egyptian counterparts”.

The bombing had forced the UK to repatriate about 16,000 tourists in 2015 as the airport’s security procedures were considered high risk.

TUI, the UK’s biggest travel company, said last year it would be resuming flights to the Egyptian resort this month.

Rival company Easyjet also said it would be restarting flights to Sharm el Sheikh.

The airline said two flights a week would depart from Manchester from 7 June, while flights from Gatwick will begin on 30 September.

The ban had sparked a steep decline in UK visitors to the region, which had previously seen hundreds of thousands of British tourists each year.

Tourists were forced to either take multiple flights or a ferry from Hurghada to visit the Red Sea destination.

It was one of the factors which led to the collapse of airline Monarch in October 2017.

Coronavirus: Americans start to leave cruise ship as Britons claim ‘we’ve been forgotten’ | World News

Published

on

The US has evacuated some of its citizens from a cruise ship quarantined over coronavirus fears.

Two charter flights carrying some of the 380 Americans on board the Diamond Princess ship moored at Yokohama Port near Tokyo had left Japan for America on Sunday, the US State Department said.

Once back in the US, the repatriated passengers will have to spend another two weeks in quarantine at a US military facility.

Of the 3,500 people on board the ship, 355 have tested positive for COVID-19, the disease caused by the coronavirus.

One US couple, Cheryl and Paul Molesky, filmed themselves boarding the flight after being kept inside their cabin for 12 days.

“Well we’re exhausted but we’re on the plane and that’s a good feeling,” Mrs Molesky said.

Her husband added they had spent “five hours on the bus, waiting to get off the bus” before boarding the flight.

Canada, Hong Kong and Italy are also planning similar repatriation flights.

Meanwhile, Britons held on the ship have accused the UK government of “forgetting” about them.

In a video message, British passenger David Abel said: “Every country except the UK has become involved, and that is really wonderful for the people on board the ship.

“Every country except for the United Kingdom.

“It feels that we’ve been forgotten. That you don’t really care about us, and that you’re actually not wanting us to come home.”

Fellow Briton Alan Steele, who was diagnosed with COVID-19 and taken to hospital while celebrating his honeymoon on the cruise ship, said it was time for Boris Johnson to “get the Brits back”.

Mr Steele, who has since tested negative for the disease, posted on Facebook: “I think it is about time boris got the brits back to england as the japanese are being totally incompetent and do not realise you cannot keep ppl in solitary confinement for 28 days without damaging their mental health. [sic]

“What does WHO [World Health Organisation] have to say about this and I am sure cruel punishment like this has to be illegal.”

News agency PA understands that the UK government is considering a repatriation flight.

A Foreign Office spokeswoman said: “We sympathise with all those caught up in this extremely difficult situation.

“We are urgently considering all options to guarantee the health and safety of the British people on board the Diamond Princess, in line with the latest advice from the Chief Medical Officer and the World Health Organisation, and are working closely with the Japanese authorities and our international partners.

“Our staff in Tokyo, including the ambassador, have been in regular contact with the British passengers and crew on the Diamond Princess and we have also been speaking to families in the UK.”

Other passengers fear they may be kept in quarantine beyond the initial 19 February deadline, after Princess Cruises president Jan Swartz said the quarantine may be extended for guests who had close contact with a person who tested positive for COVID-19.

Ms Swartz said: “We also now understand the Japanese may handle a select group of guests differently, anyone who had close contact with a person who tested positive – such as a cabin mate – may have to restart their quarantine from the date their close contact ended.”

It comes as the death toll from COVID-19 hit more than 1,773, according to the Johns Hoskins Centre for Systems Science and Engineering.

So far there have been more than 71,000 suspected and confirmed cases of COVID-19, with many of the cases concentrated in mainland China.
