Britain's aviation authority is banning all commercial Boeing 737 MAX passenger flights from UK airspace, following Sunday's fatal plane crash in Ethiopia."We have, as a precautionary measure, issued instructions to stop any commercial passenger flights from any operator arriving, departing or overflying UK airspace," the UK Civil Aviation Authority (CAA) said in a statement.Earlier on Tuesday, aviation authorities in Singapore, Australia, Malaysia and Oman temporarily suspended Boeing 737 MAX services after Sunday's MAX 8 flight from Addis Ababa to Nairobi reported technical problems and asked for permission to turn back, before crashing into a field six minutes after takeoff, killing all 157 people on board. Investigations are taking place into the cause of the crash.This is the second time in less than six months that this model has crashed soon after taking off. A new Lion Air Boeing 737 MAX 8 flight went down over the Java Sea off Indonesia last October, killing 189 people."Our thoughts go out to everyone affected by the tragic incident in Ethiopia on Sunday," a CAA spokesperson said in a statement."The UK Civil Aviation Authority has been closely monitoring the situation, however, as we do not currently have sufficient information from the flight data recorder we have, as a precautionary measure, issued instructions to stop any commercial passenger flights from any operator arriving, departing or overflying UK airspace."The UK Civil Aviation Authority's safety directive will be in place until further notice."We remain in close contact with the European Aviation Safety Agency (EASA) and industry regulators globally."In a statement, Singapore's Civil Aviation Authority announced it would suspend all variants of the Boeing 737 Max aircraft from entering or leaving the city-state, a move affecting SilkAir, China Southern Airlines, Garuda Indonesia, Shandong Airlines and Thai Lion Air.While no Australian airlines fly the 737 MAX, Australia's Civil Aviation Safety Authority said it would temporarily suspend airlines from flying all Boeing 737 MAX jets to or from Australia.Oman said on Twitter it is temporarily suspending operations of Boeing 737 MAX aircraft into and out of its airports until further notice.Malaysia announced that it would suspend the MAX 8 aircraft flying to or from and transiting the country until further notice. No Malaysian carriers currently operate the model.Airlines including Ethiopian Airlines, Aeromexico, Cayman Airways, South Africa's Comair, South Korea's Eastar Jet and Aerolíneas Argentinas and all Indonesian airlines have said they are temporarily not using the 737 MAX 8.Those decisions follow the lead of China's aviation administration, who on Monday ordered that all domestic Boeing 737 MAX 8 jets be out of the air by 6 p.m. local time, due to its principle of "zero tolerance for safety hazards."China has one of the world's largest fleets of Boeing 737 MAX 8, operating 97 of the planes, according to Chinese state-run media.The fallout has appeared to affect Boeing's bottom line. The aircraft maker's stock dropped 8% Monday, with investors voicing concerns about the 737 and 3173

Astronomers have detected the most massive neutron star ever, and it almost shouldn't even exist.Neutron stars are the smallest in the universe, with a diameter comparable to the size of a city like Chicago or Atlanta. They are the leftover remnants of supernovae. But they are incredibly dense, with masses bigger than that of our sun. So think of the sun, compressed into a major city.In the case of the newly detected neutron star, dubbed J0740+6620, it's 333,000 times the mass of the Earth and 2.17 times the mass of the sun. But the star is only about 15 miles across. It's 4,600 light-years from Earth.This is close to the limit of how much mass a compact object can contain before it crushes itself into a black hole.The neutron star itself is rapidly spinning, which is called a pulsar because they send out beams of radio waves from each magnetic pole. The beams mimic the sweeping motion of a lighthouse beam, hence the name "pulsar."Pulsars act like atomic clocks because they regularly pulse, so astronomers can use them to study space and time.The star was detected by the 1098

Canadian Prime Minister Justin Trudeau announced on Friday that his government will pay Canadian victims' families of last week's incident involving a plane being shot down in Iran.The families will receive ,000 CAD each. A total of 57 victims from Canada were on board the flight that originated from Tehran bound for Kiev. All 176 on board were killed. Late last week, the Iranian government said that unintentionally shot down the aircraft. This came after initally claiming that a mechanical error caused the plane crash. "What happened last week was nothing short of a national tragedy, " Trudeau said on Friday. "To the families and loved ones of the victims: all Canadians are mourning your loss."Trudeau hinted that economic sanctions placed on Iran adds to a challenging situation. "This is a unique and unprecedented situation because of the international sanctions placed on Iran, and the difficulties that that imposes on these families," Trudeau said."These families have lost loved ones in extraordinary circumstances, and it makes this period of grieving that much more challenging, " Trudeau added. "Our government remains firmly committed to obtaining justice for those who lost loved ones - and that includes financial compensation." 1266
