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

MARINA DEL REY, Calif. (CNS) -- Assemblywoman Autumn Burke, D-Marina del Rey, announced Monday she has tested positive for the coronavirus after apparently being exposed while the Legislature was reviewing the state budget.Her positive test led to a closure of the state Capitol in Sacramento so the Assembly offices could be thoroughly cleaned and sanitized."On July 3rd I received a call from the Assembly Human Resources Department that I had a 'mask to mask' exposure to COVID-19 on June 26th," Burke wrote on her Twitter page. "I was tested on the morning of July 4th and received my results in the evening that I had tested positive for the coronavirus."Currently my daughter and I have no symptoms, but will be remaining in quarantine until released by a doctor," she wrote. "Thank you to everyone who has reached out with well wishes. We are fine but it is of the utmost importance that everyone stay safe, be healthy & remain vigilant."The Los Angeles Times reported that four other people who work in the Capitol had also tested positive, and the building will be closed for a week.A spokesman for Assembly Speaker Anthony Rendon, D-Lakewood, told The Times there were five confirmed cases of coronavirus in the Assembly, but he declined to identify the other patients or say if they were elected officials or staffers.The state Assembly and Senate are both on recess this week. 1400

MCAS MIRAMAR (KGTV) -- Some Grand Princess passengers quarantined at MCAS Miramar say, what the President said in his address Friday about the quality care on base, is not a reality. According to the San Diego County Public Health department, two female Grand Princess passengers in their 70's have tested positive for the Coronavirus. A quarantined passenger at Miramar told 10News that not only has she not been tested, but the base also seems to be understaffed and chaotic. It was supposed to be a lovely two-week vacation around the Hawaiian Islands. "Another day in paradise… in prison," Karen Lira said.By prison, Lira means, MCAS Miramar. She and her husband Jeff have been there since late Thursday, after eight days of self-quarantine on the Grand Princess cruise ship, floating off the coast of San Francisco. "It was quite the waiting game, which just ramped up everybody's stress," Lira said.She said that stress increased tenfold after the Government diverted their vacation to San Diego. "After we left a ship at five pm, we heard it into a bus, which was a crazy situation and then crammed into a plane. And once we got onto the airport, we were told that there was no pilot for the plane," Lira said. Lira said she was baffled to see President Donald Trump on Friday, address the public on how smooth the transition from the cruise ship to Miramar played out. "We had tremendous success in Oakland, where Vice president Pence did a fantastic job," the President said."It was not smooth. It wasn't a beautiful operation," Lira responded. When they finally got to their room on base around 2 a.m. Friday, they were given a welcome note. It explained that food would be delivered to their rooms three times a day. They were advised to always wear a mask, when they stepped out of their rooms. They were also told to keep a six-foot distance from each other at all times."People found out there was food in another building, and people were going a little crazy," Lira said. "Social distancing, wear masks, stay six feet apart from each other. That went out the window immediately when we got off the ship."Lira said she wants the public to know the truth about their situation. So far, they have not been tested. They haven't even got their temperature taken since arriving in Miramar. She is hoping the situation gets better, so she can get back to Oregon, virus-free."If we are not tested any day soon, when is the clock going to start ticking? We are going to be let out of here?" Lira asked. So far, Lira and her husband are feeling healthy. At this point, they want to get tested, so that a negative result can finally get them home to Oregon. She said she is happy to continue the self-quarantine at home if necessary. 2747

MIAMI, Florida — The pedestrian bridge under construction near Florida International University was supposed to enhance safety — letting walkers and cyclists cross a busy eight-lane street with less worry after a vehicle last year struck and killed an FIU student.Instead, it collapsed Thursday, months before it was to open, crushing cars below, killing at least six people and leaving investigators with the difficult task of trying to figure out why it happened and who might be held responsible."If anybody's done anything wrong, we'll hold them accountable," Florida Gov. Rick Scott said. 606

Mardi Gras might look a bit different in 2021.Due to it being a religious holiday, the city cannot cancel Mardi Gras, but celebrating it safely amid the coronavirus pandemic is a different matter.According to the City of New Orleans' Mayor LaToya Cantrell Mardi Gras 2021 FAQ page, there will be zero parades occurring in New Orleans because "large gatherings have proven to be super spreader events of the COVID-19 virus.The official Twitter page of the city's government tweeted that Mardi Gras, which occurs the day before Ash Wednesday, "is different, not canceled.""Mardi Gras is more than just king cakes and beads, it is a religious holiday," the tweet reads. "A season of traditions that we celebrate every year, a time that the community comes together informal, fun, and often unexpected ways." 812
