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

Lyft announced on Monday that they'll provide 60 million rides to and from vaccination sites for low-income, uninsured, and at-risk communities when COVID-19 vaccines become ready.To help launch the initiative, the ride-sharing company said in a press release that it's partnering with JPMorgan Chase, Anthem Inc., United Way, Epic, Centene Corporation, Modern Health, One Medical, National Hispanic Council on Aging, National Asian Pacific Center on Aging, National Urban League, and the National Action Network."Making sure people can get to vaccination sites when they need to is mission-critical to beating this virus," Lyft Co-Founder and President John Zimmer said in a statement. "This is an opportunity to use our collective strength to mobilize on a massive scale and serve our communities. We cannot let the lack of transportation be a factor in determining whether people have access to healthcare."To make sure people living in underserved communities can get vaccinated, companies and social impact organizations would provide free or discounted rides, while its corporate partners would directly fund the rides. The community partners will also route ride credits for those in need.The news comes after Uber announced last week that it would provide 10 million free or discounted rides to help people make it to their vaccination appointments. 1365
