Maybe music artist Moby was right, and “we are all made of stars.” New research suggests the calcium in our teeth and bones came from star explosions.Researchers from Northwestern University looked at a calcium-rich supernova with x-ray imaging, which provided a glimpse into the last month of the star’s life and ultimate explosion.The findings, published in The Astrophysical Journal, suggest a calcium-rich supernova is a compact star that gives off an outer layer of gas as it’s dying. When it explodes, the star’s matter collides with material, emitting bright x-rays.The explosion is so intensely hot and high pressure, it allows nuclear fusion to produce a massive amount of calcium in mere seconds. Typically, a star creates a small amount of calcium slowly by burning helium.Half the calcium in the universe likely came from calcium-rich supernovae.“These events are so few in number that we have never known what produced calcium-rich supernova,” said Wynn Jacobson-Galan, a first-year Northwestern graduate student who led the study. “By observing what this star did in its final month before it reached its critical, tumultuous end, we peered into a place previously unexplored, opening new avenues of study within transient science.”The observed explosion was named SN 2019ehk in the Messier 100 galaxy. If that sounds a little too fantasy, just know it was 55 million light years from earth.“Without this explosion, you wouldn’t know that anything was ever there,” Margutti added. “Not even Hubble could see it.”The team was able to look at images from the Hubble Telescope of the area of SN 2019ehk before the explosion to compare before and after.The researchers are working on a follow-up study that includes how the supernova is evolving after the explosion, according to statements made to CNN. 1821

Michael Jordan has long been associated with the game of basketball, first as a six-time NBA champion with the Chicago Bulls, and currently the owner of the Charlotte Bobcats.You can now call him a NASCAR team owner.Denny Hamlin announced a partnership on Monday with Jordan as the two will form a single-car team featuring Bubba Wallace who will drive the team’s lone car. The team will begin operations in 2021.Hamlin will continue driving for Joe Gibbs Racing.“Bubba has shown tremendous improvement since joining the Cup Series and we believe he's ready to take his career to a higher level,” Hamlin said. “He deserves the opportunity to compete for race wins and our team will make sure he has the resources to do just that. Off the track, Bubba has been a loud voice for change in our sport and our country. MJ and I support him fully in those efforts and stand beside him.”Wallace became a newsmaker over the summer when a noose was discovered by NASCAR officials in his garage. NASCAR later announced that it believed that Wallace was not the target of a hate crime after investigating the origins of the noose, adding that the noose had been hanging in the garage’s stall for several months.Drivers and crew members stood in solidarity with Wallace following the incident. Fellow drivers pushed Wallace’s car to the front of the field moments before a race in June got underway.Wallace became the first Black full-time NASCAR Cup Series driver in 2018 in more than four decades. He instantly found success as a full-time driver, finishing as the runner-up of the 2018 Daytona 500.Wallace has been a vocal opponent of the use of Confederate flags at NASCAR events. During the summer, while the US debated the use of Confederate symbols, NASCAR announced it would be removing all Confederate symbols from raceways. 1829

Major domestic airlines are adjusting to a “new normal,” one that will require masks and frequent sanitization.With changes amid the COVID-19 pandemic comes some degree of normalcy on board flights. For instance on Tuesday, Delta announced that alcohol service on board domestic flights greater than 500 miles will be restored on Thursday.Also,, United Airlines and American Airlines will both be unblocking middle seats, allowing for the possibility for full flights. Delta says it will continue to block middle seats through the end of September. Southwest is also keep the middle seat on flights blocked through at least September.American Airlines said last week that its air filtration system allows for those on board flights to breathe without fear of infection.“Over the past several years, American has been further improving our HEPA filters by adding a layer of activated carbon to our filters to provide additional removal of fumes, odors and volatile organic compounds,” said Ben Thiesse, American’s Senior Engineer for the Airbus A320 Family. “Today, these carbon HEPA filters are installed on all of American’s A320 and 787 aircraft.”United Airlines says, like other airlines, it is relying upon travelers to wear face masks to keep other travelers safe."Every reputable heath institution says wearing a mask is one of the most effective things people can do to protect others from contracting COVID-19, especially in places like an aircraft where social distancing is a challenge," said United's Chief Customer Officer, Toby Enqvist. "We have been requiring our customers to wear masks onboard United aircraft since May 4 and we have been pleased that the overwhelming majority of passengers readily comply with our policy.”While Delta will continue to block middle seats, allowing customers to consume alcoholic beverages is one way the airline is returning to normal.““In keeping with the Delta CareStandard, our goal is to serve all of our food and beverage offerings in the safest way possible – both for our customers and employees,” said Allison Ausband, Delta’s Senior Vice President of In-Flight Service. “We take pride in always listening to our customers, and we know beer and wine are the adult beverages our customers want most. These selections are the first step towards a normalized beverage offering while we continue to keep customer and crew safety at the center of everything we do.” 2427

Michael Cohen said in court Wednesday that he had been living in a "personal and mental incarceration" under President Donald Trump and that his prison sentence would, ironically, help him get back his freedom.That's particularly true if he goes to a certain minimum-security prison not far from the city.In federal court on Wednesday, US District Judge William Pauley agreed to recommend that Cohen serve his 36-month prison sentence at FCI Otisville, about 70 miles northwest of New York City.FCI Otisville has sometimes been viewed as a preferable prison option for inmates convicted of white-collar crimes. In 2009, Forbes named it one of "America's 10 cushiest prisons."Despite the judge's recommendation, the decision as to where Cohen will spend time is ultimately up to the Bureau of Prisons, which has sole responsibility for determining where offenders spend their prison sentences.The decisions are made at the Designation and Sentence Computation Center in Texas. The DSCC attempts to send inmates to prisons within a 500-mile radius of their residence, which for Cohen is in New York. However, the decision also is made using a series of criteria, such as security needs, medical needs, availability of counseling services, and bed space.Bureau of Prison data shows the bureau complies with 74% of judicial recommendations, wholly or in part, according to an analysis of the DSCC published in Criminal Justice magazine in 2016.  1454
