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 massive cloud of Sahara Desert dust is blanketing the Caribbean as it heads toward the U.S. with a size and concentration that experts say hasn’t been seen in half a century. The thick dust cloud, known as the Saharan Air Layer, is making a 5,000 mile trip from the northern Africa desert to North and Central America along the east to west Trade Winds along the equator. The Saharan Air Layer is between 5,000 and 20,000 feet above the Earth's surface, and dust plumes travel over the Atlantic Ocean several times a year between spring and fall. This year's dust plume is thicker than normal, the concentration of particles in Puerto Rico are the highest in decades. Air quality across most of the Caribbean region fell to record “hazardous” levels Monday and experts who nicknamed the event the “Godzilla dust cloud” warned people to stay indoors and use air filters if they have one. 896

A video of a woman who was allegedly resisting arrest while being beaten by police officers on a New Jersey beach on Saturday has been shared 1,000s of times since being published. Emily Weinman, a resident of Philadelphia, claimed that officers questioned her about underage drinking while she was on a beach in Wildwood, New Jersey. Weinman claimed that she was given an alcohol breath test, which came back negative. Weinman added in a Facebook post that the officers from the Wildwood, New Jersey Police were going to let her go, but when she asked officers why they were enforcing underage drinking rather than more serious crimes, that is when the officers had a change of heart. Weinman said that officers asked for her to identify herself, which she refused to do. Weinman claims an officer said, "I was gonna let you go but now I'll write you up." 894

A middle school teacher and former Miss Kentucky pageant winner has been arrested and charged with sending nude photographs of herself to a 15-year-old boy, authorities said.Ramsey Bearse, a 28-year-old teacher at Andrew Jackson Middle School outside Charleston, West Virginia, allegedly sent the photos to a former student, according to the Kanawha County Sheriff's Office.The boy's parents found the photos on his phone and told police about them last week. They said their son was a student at Andrew Jackson from 6th to 8th grade and that Bearse was a teacher there during some of that time, according to a criminal complaint.In an interview with police, Bearse admitted to sending at least four photos of her topless via Snapchat from about August to October, the complaint states.She is charged with four counts of distributing obscene materials to a minor, a felony.The former beauty queen has been suspended from her teaching position and was released on a ,000 property bond after her arraignment, the sheriff's office said.Bearse, who competed in pageants under the name Ramsey Carpenter, was named Miss Kentucky in 2014.She won the preliminary talent competition at the national Miss America pageant in Atlantic City for her fiddle performance, CNN affiliate WTVQ reported at the time. Her platform issue was raising awareness about multiple sclerosis, which she was diagnosed with in 2010, WTVQ reported. 1427
