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

MIAMI SHORES, Fla. (AP) — Authorities say a Florida police officer’s wife died after becoming trapped in the back of his patrol vehicle for several hours during a hot afternoon. Investigators are treating the death of 56-year-old Clara Paulino as an accident. She died Friday afternoon while her 58-year-old husband Aristides Paulino was sleeping in their Miami Shores home after finishing a midnight shift. The Miami Herald reports Paulino woke up around 5 p.m. and started looking for his wife, finding her cell phone on the back patio. He and one of his sons found Clara in the vehicle. Officials say she had climbed into the backseat of his marked SUV to find something when the doors somehow closed, and a self-locking mechanism engaged. The vehicle has a partition between the back seat and front seat, meaning Clara could not reach the horn. “It’s literally a cage,” one Miami police officer familiar with the vehicle told the Miami Herald.Temperatures reached over 90 degrees as she spent about four hours in the vehicle. 1037

Michael Allman says his platform of "direct democracy" sets him apart from the other candidates running for the 52nd Congressional seat. At an event in La Jolla Tuesday announcing his candidacy, Allman explained how he would use technology to asses his constituents positions on major issues. Allman says  he has designed a software program that would allow voters to go online and voice their opinions. The program will ensure that only registered voters can weigh in and also makes sure they're voting just once. The investor and former energy company executive is one of several Republicans challenging Democratic representative Scott Peters in next year's election.  708
