NASA | Stellar Odd Couple Makes Striking Flares

The video discusses a system involving a hot, massive star and a compact remnant, such as a pulsar, which emits X rays and occasionally gamma rays. The pulsar's orbit brings it close to a companion star, leading to gamma ray production. In 2010, NASA's Fermi Telescope observed unexpected gamma ray flares, sparking a mystery for astronomers. Understanding this system could help predict future events and provide insights into other high mass binaries.
