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

MAMMOTH LAKES, Calif. (AP) — The Mammoth Mountain resort in California's Eastern Sierra says it has had its snowiest May on record and skiing and boarding will continue into August.The resort said Friday the 29 inches (73.6 centimeters) that has fallen so far this month bests the old mark set in May 2015.Another 6 to 12 inches (15.2 to 30.4 centimeters) of snow is expected to fall on Sunday.RELATED: May snowfall in San Diego: Mount Laguna picks up more snowThe resort had so much snow during winter that it announced skiing and boarding would continue through the Fourth of July weekend. It now plans to extend the season into August, with no specific end date set.As of Friday, Mammoth had a season accumulations of 715 inches (1,816 centimeters) at the summit, and 489 inches (1,242 centimeters) at the main lodge. 828

Michael Cohen's stunning guilty plea last week ended months of speculation about the fate of President Donald Trump's longtime personal lawyer.And now, as Cohen waits for his sentencing hearing set for December, a source familiar with his thinking says "resignation" would be a fitting word to describe the 52-year-old's mindset -- acceptance that he is headed to prison in order to protect his family."He's very resigned to doing the time. He's resigned to the fact that he's going to go to jail for some time," the person said, adding that Cohen does not believe he will receive a presidential pardon from Trump. 622

MEXICO CITY (AP) -- Mexico's top coronavirus official says definitive data on the death toll from COVID-19 won't be available for "a couple of years."The statement Sunday by Assistant Health Secretary Hugo López-Gatell is likely to revive debate about Mexico's death toll, currently at 76,430, the fourth-highest in the world.Officials acknowledge the figure is an undercount, because Mexico does very little testing. But the federal government has avoided adjusting its death toll upward to account for people who died at home or weren't tested.Some parts of the country like Mexico City have found "excess deaths" likely caused by coronavirus were at least double official figures. 691
