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 terrifying email scam using stolen passwords and sextortion is trying to scare many out of their money.There are variations of the blackmail threat, but in most cases, a password that someone once used or is still using appears in the subject line of the email.The hackers claim to have "evidence of your secret" after installing malware on adult video sites.The email explains web cameras were hacked and recordings were made of the person watching the pornography.The hackers then demand anywhere from ,000 to ,600 in bitcoin or the video will be released to all contacts, including family members and co-workers."It's a non-negotiable offer, thus please do not ruin my personal time and yours," one hacker wrote. "The clock is ticking.""It's really electronic blackmail," cybersecurity expert Tim Dimoff said. "This is a very well-structured blackmail. Boy, it looks believable."However, it's all a nasty scam. There are no videos and the hackers may have one of your passwords, but they don't have all of your information."If you look in the body of the email, they're not using your name. They're not saying what specific website you might be going to and they don't have a screenshot of you," said Christy Page, the president and CEO of the Better Business Bureau in Akron.Page said more than 130 complaints have reported nationwide through BBB's scam tracker.It's not clear how many of those people gave up the ransom, but it's estimated 0,000 has been paid this year by people frightened by the threat."The fear of embarrassment can be very powerful to get you to part with your money," Page said.Dimoff and Page said the hackers likely used the dark web to buy passwords that were stolen during data breaches and the hackers can be very difficult to track.Page said anyone who receives the email should not pay any money or respond to it.  However, passwords should be changed immediately.In addition, Page said people should consider using a password manager and a web camera cover for extra peace of mind. Some BBB offices offer the covers for free.Consumers who want to find out if their passwords have been compromised can go to the security website Have I been Pwned which collects information on data breaches. 2272

A non-profit in California has developed a way to capture poachers who snatch sea turtle eggs - building lookalike eggs with GPS trackers constructed inside them.According to research published Monday in the journal Current Biology, the InvestEGGator is a 3D-printed life-like turtle egg that can be tracked as far away as 137 kilometers (85 miles)."It replicates the appearance, weight, and feel of a real turtle egg. It is easily deployed at low risk to investigators, can be programmed and monitored remotely using web-based and smartphone applications, and is a low cost, allowing for deployment of many units at once," the company said on its website.The decoy eggs are placed in real nests alongside real eggs, which are monitored and mapped every time they are moved, said the Ventura-based Paso Pacífico, the non-profit that developed the eggs.The research showed that the decoy eggs provide a signal once every hour."Using data provided by the decoys, we identified trafficking routes and on two occasions properties of potential interest to law enforcement," researchers said in the journal. "Decoys also yielded anecdotal information, furthering our understanding of trafficking routes." 1206

A Philadelphia-area Dunkin' Donuts employee is accused of selling meth and heroin while in uniform, even sometimes using the store's drive-thru window for illegal activity, CBS Philadelphia reported. The Lancaster County District Attorney’s Office claims 35-year-old Nathan Wade Pizzardi was seen selling illegal drugs while on duty. Investigators told CBS Philadelphia that he was spotted in August and September selling heroin and meth. Law enforcement claims that Pizzardi would sell the drugs using the store's drive through, or sometimes would make transactions in the parking lot, while in uniform. Pizzardi has been charged with a pair of felony drug offenses, and is facing an ,000 bond. 751
