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

MESA AND GARFIELD COUNTIES, Colo. — The Pine Gulch Fire in Colorado grew more than 37,000 acres Tuesday night into Wednesday, according to the Rocky Mountain Area Coordination Center. It's now 125,108 acres and the second-largest wildfire in Colorado history.At more than 125,000 acres, the fire has surpassed the size of 2018's 108,045-acre Spring Fire. 362

MAMMOTH LAKES, Calif. (AP) — A late spring storm has soaked parts of Southern California with record rainfall.The National Weather Service says Thursday that downtown Los Angeles got .48 inches of rain, a record for the date. A half-dozen other records were set, including Santa Barbara, which got nearly an inch of rain.The storm also dumped fresh snow in the Sierra Nevada, where the seasonal snowpack and rainfall totals already are well above normal.RELATED: Check today's forecastAuthorities rescued four hikers caught in the weather on the far north's Redwood Coast and two people trapped on a tiny island in the suddenly fast-flowing Los Angeles River. 667

McLEAN'S TOWN CAY, Bahamas (AP) — Hurricane Dorian ravaged the northern Bahamas as a catastrophic Category 5 storm, its record 185 mph (297 kph) winds ripping off roofs, overturning cars and tearing down power lines as hundreds hunkered down in schools, churches and shelters.Dorian slammed into Elbow Cay in Abaco island at 12:40 p.m. Sunday, and then made a second landfall near Marsh Harbour at 2 p.m., after authorities made last-minute pleas for those in low-lying areas to evacuate."It's devastating," said Joy Jibrilu, director general of the Bahamas' Ministry of Tourism and Aviation. "There has been huge damage to property and infrastructure. Luckily, no loss of life reported."Video that Jibrilu and government spokesman Kevin Harris said was sent by Abaco residents showed homes missing parts of their roofs, downed power lines and smashed and overturned cars. One showed floodwaters rushing through the streets of an unidentified town at nearly the height of a car roof.In some parts of Abaco, "you cannot tell the difference as to the beginning of the street versus where the ocean begins," said Prime Minister Hubert Minnis.According to the Nassau Guardian, he called it "probably the most sad and worst day of my life to address the Bahamian people."Silbert Mills, owner of the Bahamas Christian Network, said trees and power lines were torn down in Abaco.Jack Pittard, a 76-year-old American who has visited the Bahamas for 40 years, decided to ride out the storm — his first hurricane — in Abaco.He said he battened down his house to spend the storm in a nearby duplex. He noted the ocean is quite deep near where he was staying, and there is a cay that provides protection.A short video from Pittard about 2:30 p.m. showed winds shaking his home and ripping off its siding.Harris, the government spokesman, said Dorian could affect 73,000 residents and 21,000 homes. Authorities closed airports for Abaco, Grand Bahama and Bimini, but Lynden Pindling International Airport in the capital of Nassau stayed open.The archipelago is no stranger to hurricanes. Homes are required to have metal reinforcements for roof beams to withstand winds into the upper limits of a Category 4 hurricane, and compliance is generally tight for those who can afford it. Risks are higher in poorer neighborhoods, with wooden homes in low-lying areas. 2356
