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 US service member and a member of the UK armed forces were killed in an improvised explosive device attack in the Manbij area of Syria on Thursday.A US official with knowledge of the initial reports from the battlefield told CNN the American had been killed.The UK Ministry of Defence confirmed the British death in a statement saying the soldier was embedded with US forces on a counter ISIS operation when the incident occurred."The family has been notified and our thoughts are with them at this difficult time," the British statement continued.Two members of the US-led coalition in Syria were killed and five were wounded in the attack, the coalition said. The official said that multiple vehicles were involved in the IED incident.The coalition said details about the incident are being withheld pending further investigation and that the names of those killed will be released "at the discretion of the pertinent national authorities."The US maintains about 2,000 US troops in Syria, who mostly work with local allies fighting ISIS in Syria.President Donald Trump said Thursday that the US would "be coming out of Syria like very soon," just hours after the Pentagon highlighted the need for US troops to remain in the country for the immediate future.Chief Pentagon spokesperson Dana White told reporters that "important work remains to guarantee the lasting defeat of these violent extremists" in the country.The-CNN-Wire 1440

A South Florida pediatrician is helping parents stay informed about the effects of the coronavirus on children."I always tell parents, listen to your sixth sense," said Dr. Marcos Mestre with Nicklaus Children's Hospital in Miami.Mestre said that most children infected with COVID-19 experience mild symptoms and do "incredibly well" and don't need to admitted to the hospital. But, he added that children with underlying health conditions like a compromised immune system, obesity, or asthma may be at greater risk of having complications."Their hospitalization, if they need to be hospitalized, might be a little bit longer," Mestre said.WATCH INTERVIEW WITH PEDIATRICIAN: 682

A total of 173 sea turtles died off Cape Cod, Massachusetts, this week because of the extreme cold, according to Mass Audubon Director Bob Prescott.Prescott said 227 cold-stunned turtles were recovered from the Gulf of Maine since Wednesday, but only 54 lived. Mass Audubon, the largest nature conservation nonprofit in Massachusetts, regularly patrols the beaches this time of year looking for cold-stunned turtles, Prescott said.But this was many more than they expected, he said. 490

A steady gust of a late autumn's wind is about the only thing moving quickly in rural corners of this country. But Pamela Curry has learned that the solitude she loves about her home in this remote part of Maryland can come at a price.It was 2017 when the Curry family's home in rural Maryland caught fire. Curry, her husband and kids happened to be on vacation at the time."Everything you worked for, everything you had, was gone," the mother of four said while sitting on the front porch of the home she now lives in.The first firefighters who arrived were from the Denton Volunteer Fire Company, a 10-mile drive from the Curry's home in Caroline County.Todd Berneski was there that night and serves as the department's president."We’re here to provide a service to the community," Berneski said.That service that Curry's and others in rural communities across the country depend on though has been struggling lately. Since COVID-19, this volunteer fire department and others nationwide suddenly lost revenue from yearly fundraisers. Denton Volunteer Fire Company is looking at a ,000 budget shortfall right now.What that means is that volunteer fire agencies nationwide are struggling to keep up with maintenance on equipment. While there are no salaries to pay, it still costs hundreds of thousands of dollars to run these departments.All of it is putting the public at risk."If we show up and pumps don’t work or we don’t have tools, there’s nobody else to call," Berneski said about the constant struggle to keep aging equipment running.Across the country, there are close to 25,000 volunteer fire departments, most of which serve as critical lifelines to rural communities. In Denton, they were able to hold their annual Christmas tree farm fundraiser, but their budget is still off by 25 percent."People want to give. We know they want to give, but if someone can’t afford to give, I don’t want to take a meal off of somebody’s table because they can’t afford it," Berneski added.The National Volunteer Fire Council is worried about the long-term implications the funding gap could create. They've successfully lobbied Congress for millions of dollars in aid for volunteer departments, but the money is held up in the current stimulus bill.The concern is that some agencies may be forced to close if they don't get help."You’re probably not going to know you have a problem until you have a very big problem," said David Finger, who works with the National Volunteer Fire Council.As for Pamela Curry, she knows firsthand how vital these volunteer fire departments are and how critical it is to keep them running."Their equipment has to be running. If their equipment isn’t running and it’s not in good order, we won’t have machines to help us out,” Curry said. 2779
