The world’s top astronomical body has endorsed the definition of the “Astronomical Unit” (AU), a measurement used to calculate the distance between stars and planets.
The AU — based on the distance between Earth and the Sun — has long been in use by astronomers, and the decision by the International Astronomical Union (IAU) simply removes a tiny three-metre (10-feet) margin of error.
“Until now, the value in metres of AU was determined experimentally, depending on the models, observations and reference system that was used,” it said.
Officially, the AU is 149,597,870,700 metres (149,597,870.7 kilometres or 92,955,807.273 miles) exactly.
The ruling was approved at the IAU’s general assembly in Beijing from August 20-31, the Paris Observatory said on Friday in a press release.
‘NPR will not be intimidated’: Mike Pompeo blasted for attacks on reporter Mary Louise Kelly
National Public Radio (NPR) is standing by "All Things Considered" host Mary Louise Kelly after she was attacked by Secretary of State Mike Pompeo.
"One day after a contentious interview followed by an expletive-filled verbal lashing of NPR host Mary Louise Kelly, Secretary of State Mike Pompeo is publicly accusing her of lying to him — 'twice,'" NPR reported. "He does not explain how and offers no evidence, but in their recorded interview the nation's top diplomat declined to respond when Kelly asked if he owed an apology to Marie Yovanovitch, the former U.S. ambassador to Ukraine who was ousted from that post last year after allies of President Trump accused her of disloyalty."
Trump lawyers argue ‘the president did absolutely nothing wrong’ as GOP presents impeachment trial defense
White House lawyers began their defense of Donald Trump at his historic Senate impeachment trial on Saturday, saying the president did nothing wrong in his dealings with Ukraine and American voters -- not Congress -- should decide his fate.
White House counsel Pat Cipollone said it would be a "completely irresponsible abuse of power" if the Senate follows the lead of the House of Representatives and votes to remove the 45th US president from office.
"They're asking you to do something that no Senate has ever done," Cipollone told the 100 senators gathered on a rainy Saturday morning for a rare weekend session at just the third impeachment trial in US history.
Louise Linton defended Greta Thunberg against her husband’s attack — but deleted her comments in less than an hour
The wife of Treasury Secretary Steven Mnuchin stood up against her husband online on Saturday, but quickly deleted her comments.
At the World Economic Forum, Mnuchin told climate action activist Greta Thunberg to "go study economics."
"I stand with Greta on this issue. (I don’t have a degree in economics either)," Linton posted on Instagram.
"We need to drastically reduce our use of fossil fuels," she explained.
"Keep up the fight @gretathunberg," she urged.
