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 study by the Institute for Health Metrics and Evaluation found in the past 10 years, the number of deaths attributed to alcohol has gone up 35 percent. Among women, alcohol-related deaths soared 85 percent.Ron and June Byrd know the pain of watching a loved one struggle with alcohol. They helplessly watched their daughter, Erika, fight it for years.“It would have to be in all caps: helpless. As a father, I was supposed to be able to fix things. I couldn't fix it,” Ron Byrd says.After becoming partner at her law firm, doctors diagnosed Erika with breast cancer. Her parents say she became depressed, and it made her drinking worse.Rehab didn’t work.“Despite our best effort, her friends’ best efforts, her best efforts, it was to no avail,” says Ron. “And it killed her.”Erika died in 2011 at the age of 42.Her death is part of a disturbing, growing trend.“I just know it's a terrible epidemic,” Ron says. “Alcohol kills you in many ways: suicides, accidents, organ failures, disease.”The study by the Institute for Health Metrics and Evaluation found this spike started during the recession and that growing pressure on working mothers might also play a role.“They are, I think, by in large, ashamed of it. Our daughter was,” Ron says. “They do their best to hide it until they can't.”Erika's parents hope the report helps break the stigma associated with alcoholism and leads to more resources devoted to fighting the problem. 1447

A vehicle was intentionally driven Friday into three students outside a high school near the southern French city of Toulouse, injuring them, the country's interior ministry said.A driver was arrested after the collision, and the Toulouse prosecutor has been called to investigate, the ministry said.The collision happened outside Saint Exupéry high school, according to CNN affiliate BFM TV.Initial information about the conditions of the injured -- identified by authorities only as Chinese students -- conflicted. The interior ministry said the students were lightly injured; BFM reported that two were in serious condition.Toulouse Prosecutor Pierre-Yves Couilleau said around noon ET that two students remained hospitalized and one had left the hospital.The vehicle accelerated as the students crossed a road, the interior ministry said.The driver has a history of mental illness, the interior ministry said in a statement. The incident doesn't initially appear to be related to terrorism, the interior ministry said.Developing story - more to come  1067

A pair of studies released in recent days show how the worst of the economic woes have hit lower-income and minority Americans.According to Pew Research, 46% of lower-income Americans have trouble paying bills since March. The data also indicated that 51 % of lower income Americans have had more difficulty saving money since the start of the pandemic.For those considered “upper income,” just 21% say were saving less money than before the pandemic, compared to 25% of upper-income Americans who were able to save more, according to Pew.Pew’s data also showed that minorities were much more likely to be financially impacted. The data showed that 11% of whites received assistance from a food pantry or food bank since March, compared to 33% of Blacks and 30% of Hispanics.The data also showed that Blacks and Hispanics were two times more likely to have difficulty paying bills.A study by Harvard released earlier this month showed similar data.The data found that 71% of Americans with a household income of less than ,000 faced financial difficulty amid the pandemic, compared to 20% of households making more than 0,000. The data also found that 72% of Latinos and 60% of Blacks faced financial burdens compared to 36% of whites. 1250

A suspect who had barricaded himself on Tuesday in his Panama City, Florida, home after an earlier shooting was later found dead in the residence, authorities said.The Bay County Sheriff's Office identified the dead suspect as 49-year-old Kevin Robert Holroyd.One person had a minor injury and was transported to a hospital, city spokeswoman Caitlin Lawrence said earlier Tuesday.The hunt for Holroyd, who was wanted in connection with a homicide in Santa Rosa Beach in Walton County, ended with his death about 57 miles southeast in Bay County, after he opened fire on police, the Bay County Sheriff's Office said.Authorities did not say how Holroyd died.The Bay County Sheriff's Office and Panama City police began searching for Holroyd in case he returned to Bay County. Investigators started watching Holroyd's townhome apartment after his vehicle was seen there. During that time, a complex resident called the fire department to report a gas smell, the sheriff's office said.The investigators got out of their cars to find out why firefighters had arrived in the complex parking lot, authorities said.From an upstairs window of the apartment, Holroyd opened fire on the firefighters and investigators, and other responding officers, including Panama City police, the sheriff's office said.About 100 rounds were fired during the gunbattle, the sheriff's office said.At one point, two Panama City officers and a sheriff's deputy were pinned down behind their vehicles by the gunfire, the sheriff's office said.Photos from Eryn Dion of the Panama City News Herald showed a heavy police presence in the area during the standoff.Stacie Houchins said she did not see the incident start, but she decided to go to the scene to see what was going on. She shared photos with CNN of police with weapons drawn.When she arrived on the scene, she said she heard multiple loud gunshots. She said the gunshots seemed like rapid fire.SWAT officers eventually entered the townhome through an upstairs window, and officers found Holroyd's body clad in body armor. The inside of the home had been saturated with gasoline, authorities said.Authorities found several hundred rounds of ammunition, several high-powered rifles and flares, the sheriff's office said. Authorities believe Holroyd had planned to use the flares to ignite the gasoline.No other details on the homicide in Santa Rosa Beach were immediately available.The-CNN-Wire 2429
