Astronomers at the University of Minnesota Duluth and the North Carolina Museum of Natural Sciences have identified a new class of ring galaxy. Named PGC 1000714, it features an elliptical core with not one, but two outer rings. It’s the only known galaxy of its kind in the known universe.
Glensheen Historic Estate is a large mansion located in Duluth, Minnesota. It was constructed to be the family home for Chester Adgate Congdon in 1908. In 1968, the mansion was given to the University of Minnesota Duluth. While the university owned the home, Elisabeth Congdon, Chester’s youngest daughter, was given a life estate while allowed her to occupy the mansion until her death. Without a doubt, the house is an absolute beauty, however, it’s more commonly known for its brutal 1977 murder.
On 26 June, 1977, somebody snuck into the Glensheen Mansion. Inside, they came across Elisabeth’s nurse, Velma Pietila, who they threw down the stairs before bludgeoning her with a candlestick. Following her murder, the intruder then crept into 83-year-old Elisabeth’s bedroom and suffocated her with her own pillow.
Roger Caldwell, the husband of Elisabeth’s adopted daughter, Marjorie, was eventually apprehended for the shocking murders. Initially, he denied the crime and was acquitted, but years later he eventually confessed that he killed them because Marjorie was to inherit the Congdon fortune when Elisabeth passed away. Following Roger’s confession, he committed suicide.
