The Nordic Nova Society is a group of people that study stars. Mr. Hassel was given his own stars to study. He was still not happy because was not given very big area to study.
He was very excited when the farm got new electric lights because he could read his books at night. He studied books and taught himself how to find stars. One night he was looking at the stars using glasses. He saw a star no one had ever seen before.	Mr. Hassel wearing his glasses. Picture courtesy of Rune Anda

One night he was studying the stars and he saw something he had not seen the night before. It was a comet. He had to wait until the next day to tell the astronomical observatory because he could not use a phone. The comet was named after him and two other astronomers who had also seen it. It was named "Comet Jurlof-Achmarof-Hassel".	Comet Jurlof-Achmarof-Hassel Picture Courtesy of Rune Anda
