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

MADISON, Wisc. -- The classic holiday song "Baby It's Cold Outside," has been pulled from a Madison, Wisconin radio station's airwaves.According to our partners at WISC-TV, Mid-West Family Broadcasting Program Director Fletcher Keyes said he took all versions of "Baby It's Cold Outside" out of rotation on Hank AM 1550 and 97.7 FM Monday. Keyes said that the song was pulled because "it's describing a scenario that wouldn't be OK today, so we didn't feel that we had to have it." He also said that he thinks the song could bring up bad feelings. The song was also pulled from a Cleveland radio station last week.“It really pushed the line of consent,” Cleveland Rape Crisis Center President and CEO Sondra Miller told local news in that city.For more information, click here. 825

LOUISVILLE, Ky. — Voters have rebuffed President Donald Trump and nominated two Republicans he opposed to House seats from North Carolina and Kentucky. In western North Carolina, GOP voters picked 24-year-old investor Madison Cawthorn over Trump-backed real estate agent Lynda Bennett. In Kentucky, Rep. Thomas Massie easily defeated his Republican challenger, Todd McMurtry. In March, when Massie held up the passage of a coronavirus stimulus bill by signaling he was a "no" on a key procedural vote, Trump called him a "grandstander" and called for his removal from the party.Calls in higher-profile races in Kentucky and New York face days of delay as officials count mail-in ballots. One of Tuesday's top races involves former Marine combat pilot Amy McGrath's fight for the Democratic nomination to challenge Senate Majority Leader Mitch McConnell this November. She faced a challenge from underdog progressive Democrat Charles Booker. The other involves House Foreign Affairs Committee Chairman Eliot Engel of New York, who is seeking a primary win over another progressive candidate, Jamaal Bowman. Engel is seeking a 17th House term. 1149

MARION COUNTY, Fla. — A Florida woman was arrested on Tuesday after deputies say six children in her care were living in some of the worst living conditions they've ever seen.Marion County, Florida Sheriff’s Office deputies arrested Sara Nicole Resko, 30, after some of the children were found wandering in the street on Tuesday afternoon. Deputies say that a 2-year-old girl and a 4-year-old boy were found wandering in the road alone. The little girl was not clothed from the waist down and a witness provided a towel to the child so she could cover up. Deputies say they immediately saw that both children were infested with lice and covered with open sores.The little girl was in worse condition than the little boy, having multiple open sores on her arms, legs, chest, back, feet and face, deputies say.While deputies were trying to figure out where the two children came from, they saw more children riding bicycles down the roadway, later identified as the siblings of the two and 4-year-old.These children, ages 6, 8, 9 and 13, told deputies that Resko had left them alone at the home while she was at work.Deputies entered the home and found that there was no running water, no food and no electricity. The floor was covered in dog feces and the home was infested with flies. The home was in complete disarray and the children were only given mattresses on the floor with no linens to sleep on, deputies say. All of the children had open sores and lice on them as well.After deputies had been on scene for an hour and a half, Resko finally arrived at the home. She told deputies that she had just been gone for a few minutes, but quickly began changing her story once deputies told her how long they had been there investigating.MCSO says that upon further review of Resko’s history, deputies found two previously reported incidents where the children had been left unsupervised. The Department of Children and Families responded to an incident on February 2, and implemented a supervision plan with Resko, who was instructed to not allow the 13-year-old to babysit the other children anymore.Deputies ultimately determined that Resko failed on multiple occasions to provide care and supervision for these children. DCF responded and took custody of the six children. Resko was arrested and charged with six counts of Child Neglect.Resko is being held on a ,000 bond. 2412
