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 Pro Football Hall of Fame inductee in 2017, former Arizona Cardinals quarterback Kurt Warner revealed he thought about making a return to the NFL in 2018.During a baseball game in St. Louis on Monday, the 46-year-old Warner said he reached out to a team about possibly returning for the 2018 season, a good eight-plus years after his most recent NFL appearance."I was actually ready to (return) for this coming season," Warner said. "I actually talked to a coach, and my wife said, 'Go for it, I think it would be great.' So, I actually talked to a coach about possibly doing it if they needed someone, but they went out and signed somebody. I don't think they thought I was serious."  700

A standoff between police and an armed suspect that resulted in one officer's death and the wounding of another remains underway Saturday afternoon in Pomona, California, near Los Angeles, more than 15 hours after it began.The suspect is barricaded inside an apartment home after fatally shooting an officer and wounding a second one, according to the Los Angeles County Sheriff's Department."It is with a heavy heart that I must report that one officer did not survive," Pomona police Chief Michael Olivieri tweeted early Saturday morning. "The second officer is in stable condition."  599

A New York City woman is taking to social media in hopes of using her voice and her story to make a difference for Black women fighting breast cancer. According to the CDC, breast cancer death rates are 40 % higher among Black women then white women.Suzette Simon wears a superhero costume to chemotherapy, and says, she's armed with superhero strength. She's also taking social media by storm, filming things like "live from chemo.""I’ll do a dance duet but then at the bottom, I’ll say yah I’m dancing, but I want you to know 40% of Black women who get cancer die from it,” Simon said.For Simon, this fight is personal. It started 30 years ago when her mom, Aline, a Black woman who had no health insurance, died alone in a New York public hospital at age 62.“I don’t think she had an advocate and I think that’s part of the reason why I do this, because she didn’t have an advocate,” Simon said.“Now that I’m going through my own cancer, I want to use it to advocate for others. I want to use my superpowers,” Simon said. “I come from television. My background is comedy and so I have superpowers. I want to make people happy I want to make people laugh.”She was diagnosed in January and has decided to put her creativity and energy on the internet. She hopes to educate and empower black women.“Harriet Tubman had strong Black boobs, Rosa Parks had strong Black boobs, but they didn’t have a superhero, and 42% of those strong Black boobs got cancer,” Simon said. “Maybe not them, but there are a lot of heroic women with strong Black boobs that got cancer so I’m here to be that superhero for those women with strong Black boobs.”The CDC states that breast cancer is found earlier in white women and that the number of cases is higher among Black women who are younger than 60 years old.Dr. Caroline Elistin, assistant dean of faculty at Chamberlain University College of Nursing, says there's a reason behind the disparities in healthcare.“I believe that trust has something to do with it. In the current workforce diversity amongst physicians is limited- you want the individual who is caring for you and trust them -when they look like you,” said Dr. Elistin said, who works in medical oncology in South Florida. She says breast cancer is just one of the types of cancer she treats.“Mounting evidence suggests when physicians and patients share the same race or ethnicity, it improves the time spent together the medication adherence the decision making- wait times with treatment as well,” Dr. Elistin said.Those in poorer areas she says, don't have the same opportunities, which leads to a lack of success. And that is just one aspect of the societal problem.“Has this breast surgeon ever worked with Black women? It became a journey,” Simon said. “I was not going to be my mom, in a hallway trying to get help. I was not going to be that person.”The #strongblackboobs movement lives on, she says, through smiles and joy, even in pain.“And just laughing through the most difficult time of life- it's a funny time- when you know you could die it's the funniest time ever- you’ve gotta have a good time,” Simon said.And she says, you have to spread the message of awareness, which is just one aspect of her movement to make a difference. 3253
