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 suspect wanted in the fatal shooting of a prominent Houston cardiologist is the subject of an arrest warrant, Houston police said at a news conference on Wednesday.Joseph James Pappas, 65, is the suspect, Chief Art Acevedo said. He has not been seen for the past two days, the chief said.Acevedo told reporters a tip came in Tuesday after surveillance video released a day before showed the suspect, whom someone said they recognized.The suspect's mother was a patient of the doctor and died during surgery 20 years ago, Acevedo said.Dr. Mark Hausknecht, who treated former President George H.W. Bush, was fatally shot as he rode to work at Houston Methodist Hospital on July 20.The renowned cardiologist and the suspect were seen shortly before the shooting riding their bicycles on South Main Street, police said. 825

A neo-Nazi couple who named their child after Adolf Hitler have been found guilty Monday of being part of a banned right-wing group in England.Adam Thomas, 22, and Claudia Patatas, 38, were convicted at Birmingham Crown Court in the country's West Midlands region for being members of the extreme right-wing organization, National Action. The group was banned in 2016.According to the UK's Press Association news agency, the court heard that the couple gave their child the middle name "Adolf" after Hitler, because of Thomas' "admiration" for him.Photos were also recovered from the couple's home that showed Thomas dressed in the white robes of the Ku Klux Klan while holding his son, according to PA.The jury were also shown a tattoo Patatas has, which reproduces an intricate floor design from inside a former SS headquarters at Wewelsburg Castle in Germany, PA said.The court heard how members of National Action had several methods to disguise their contact with each other and used closed encrypted messaging platforms to organize meetings to spread their ideology.The group was banned by the UK's former home secretary, Amber Rudd, after she called it "racist, anti-Semitic, and homophobic."Rudd added that it is an "organization which stirs up hatred, glorifies violence, and promotes a vile ideology, and I will not stand for it. It has absolutely no place in a Britain that works for everyone."The group was outlawed after it had celebrated the?murder of Labour Party member of Parliament Jo Cox.As part of the same trial, 27-year-old Daniel Bogunovic was also found guilty for being part of the group and three other men admitted they were members prior to the case, West Midlands Police said.The couple and the four other men will be sentenced in December, PA reported.Speaking after the verdict, the head of West Midlands Counter Terrorism Unit, Matt Ward, said those convicted "were not simply racist fantasists.""We now know they were a dangerous, well-structured organization," he said in a statement on the West Midlands Police website."Their aim was to spread neo-Nazi ideology by provoking a race war in the UK and they had spent years acquiring the skills to carry this out. They had researched how to make explosives. They had gathered weapons ... Unchecked they would have inspired violence and spread hatred and fear across the West Midlands."Ward said that the convictions dealt a significant blow to National Action. "We have dismantled their Midlands Chapter but that doesn't mean the threat they pose will go away," he added.So far, a total of 10 people have either been convicted or admitted they are members of National Action, according to PA. 2687

A top ranking member of the Sheriff’s Department is speaking about changes he feels are needed, following the investigation into Assistant Sheriff Rich Miller.On Tuesday, Team 10 confirmed Miller was being accused of inappropriate conduct. Miller is currently using his accumulated time off until his scheduled retirement on March 2nd.Commander Dave Myers, who is running for Sheriff, emphasized women should feel safe to come forward. He used the example of Deputy Richard Fischer, accused by more than a dozen women of sexual misconduct while on duty.“It took after a woman complained… another 13 women to come forward before anything was really done. If we can’t police ourselves within the department, how’s the public going to trust us to do that outside the department?” Myers said.Myers has been with the department for 32 years.“One of my goals is to create that transparency,” Myers said.Sheriff Gore told Team 10 in regards to Miller, “allegations are taken very seriously and given the highest priority.” 1023
