“SS 433 is an unusual star system and each year something new has come out about it,” said Segev BenZvi, physicist at the University of Rochester. “This new observation of high-energy gamma rays builds on almost 40 years of measurements of one of the weirdest objects in the Milky Way. Every measurement gives us a different piece of the puzzle, and we hope to use our knowledge to learn about the quasar family as a whole.”
