A mysterious cigar-shaped object spotted tumbling through our solar system last year may have been an alien spacecraft sent to investigate Earth, astronomers from Harvard University have suggested.The object, nicknamed 'Oumuamua, meaning "a messenger that reaches out from the distant past" in Hawaiian, was first discovered in October 2017 by the Pan-STARRS 1 telescope in Hawaii.Since its discovery, scientists have been at odds to explain its unusual features and precise origins, with researchers first calling it a comet and then an asteroid, before finally deeming it the first of its kind: a new class of "interstellar objects."Now, a new paper by researchers at the Harvard Smithsonian Center for Astrophysics raises the possibility that the elongated dark-red object, which is 10 times as long as it is wide and traveling at speeds of 196,000 mph, might have an "artificial origin.""'Oumuamua may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization," they wrote in the paper, which has been submitted to the Astrophysical Journal Letters.The theory is based on the object's "excess acceleration," or its unexpected boost in speed as it traveled through and ultimately out of our solar system in January 2018."Considering an artificial origin, one possibility is that 'Oumuamua is a light sail, floating in interstellar space as a debris from an advanced technological equipment," wrote the paper's authors, suggesting that the object could be propelled by solar radiation.The paper, written by Abraham Loeb, professor and chair of astronomy, and Shmuel Bialy, a postdoctoral scholar, at the Harvard Smithsonian Center for Astrophysics, points out that comparable light-sails already exist on earth."Light-sails with similar dimensions have been designed and constructed by our own civilization, including the IKAROS project and the Starshot Initiative. The light-sail technology might be abundantly used for transportation of cargos between planets or between stars."In the paper, the pair theorize that the object's high speed and its unusual trajectory could be the result of it no longer being operational."This would account for the various anomalies of 'Oumuamua, such as the unusual geometry inferred from its light-curve, its low thermal emission, suggesting high reflectivity, and its deviation from a Keplerian orbit without any sign of a cometary tail or spin-up torques."'Oumuamua is the first object ever seen in our solar system that is known to have originated elsewhere.At first, astronomers thought the rapidly moving faint light was a regular comet or an asteroid that had originated in our solar system.Comets, in particular, are known to speed-up due to a process known as "outgassing," in which the sun heats up the surface of the icy comet, releasing melted gas. But 'Oumuamua didn't have a "coma," the atmosphere and dust that surrounds comets as they melt.Multiple telescopes focused on the object for three nights to determine what it was before it moved out of sight. 3063

A new Trump administration border policy requiring that asylum seekers at the southern border remain in Mexico while their claims are processed has garnered the incoming Mexican government's support, the Washington Post reported Saturday, citing Mexican officials and senior members of Mexican president-elect Andrés Manuel López Obrador's transition team.The plan, called "Remain in Mexico," emerged after a meeting in Houston last week that included Mexico's incoming foreign minister Marcelo Ebrard, Secretary of State Mike Pompeo, Homeland Security Secretary Kirstjen Nielsen, and other high ranking US officials, US and Mexican officials told the Post.In a statement Thursday, Pompeo said that he, Nielsen and Ebrard had met "to discuss the migrant caravans.""We have affirmed our shared commitment to addressing the current challenge," he said. "The caravans will not be permitted to enter the United States."US officials began receiving guidance on "Remain in Mexico" this week and were told it could be implemented soon, the Post reported, but US and Mexican senior officials stressed that elements of the plan had not yet been established and that no formal agreement has yet been signed.If put into effect, it would end the current practice of asylum seekers remaining in the United States while their applications are processed, the so-called "catch and release" by President Donald Trump, who is a vocal opponent of the practice."For now, we have agreed to this policy of Remain in Mexico," Olga Sánchez Cordero -- López Obrador's top domestic policy official as Mexico's interior minister-elect -- told the Post, calling it a "short-term solution." 1669

A statue depicting President Donald Trump in the nude will be displayed at The Haunted Museum in Las Vegas after being purchased by a paranormal investigator and TV show personality.Zak Bagans paid ,000 for the statue, called "The Emperor Has No Balls," at an auction in Los Angeles on Wednesday. Bagans is the host of "Ghost Adventures" on the Travel Channel.He owns The Haunted Museum, which features winding hallways and secret passages, and is said to be haunted by spirits. It has hundreds of possessions on display, according to the attraction's website.Visitors to the museum must sign a waiver before entering.The statue is one of a series that depicted Trump in the nude and missing testicles. It was created by an artist collective called Indecline and is the only one remaining that was not vandalized or destroyed, the New York Post reports.One of the statues in the series appeared in Union Square in New York City. 959
