After weeks of rumors and unconfirmed reports, European scientists have officially announced the discovery of an Earth-sized world around the closest star to the Sun, Proxima Centauri. Although the planet theoretically orbits its star in a region where water could exist as a liquid on its surface, no direct information can be gleaned about whether Proxima b has an atmosphere, water, or other characteristics that would increase its habitability. Nonetheless, it is tantalizing to imagine a habitable world so close to home.
The existence of a likely terrestrial world orbiting Proxima Centauri, which is 4.2 light years from the Sun and part of a three-star system that includes two distant members, Alpha Centauri A and B, has been speculated about for some time. That's because Guillem Anglada-Escudé, an astronomer at the Queen Mary University of London, and colleagues used spectrograph data from the European Southern Observatory in Chile during the 2000s to discern a wobble in the star’s movement.
Then, earlier this year, with a concerted observing program over 60 nights at the observatory, they gathered additional data to rule out other explanations for Proxima Centauri's wobbling, such as flares or other stellar activity. It had to be the gravitational effect of a nearby planet. “Statistically, there can be no doubt now,” Anglada-Escudé said during a telephone news briefing about the findings, published Wednesday in Nature.
On Monday, Pence struggled when a Fox reporter asked him Monday about Trump's contention that, in 2020, he would win 95 percent of the African American vote. Pence laughs, the reporters asks why he's laughing.
Police in Hyannis, Massachusetts were on the lookout for 31 year old Shaun Miller, who was wanted for drug trafficking. Officers went to a house were he was believed to be staying, and when they encountered an "elderly man" there, the "officers determined that the ‘elderly man’ was in fact Miller, and at that point, officers pulled off Miller’s realistic disguise and placed him under arrest," according to a statement issued by the US Attorney’s Office.
