A powerful X-ray pulsar is whipping around its stellar partner at a record-breaking speed! These two stars orbit each other every 38 minutes, less than the amount of time it takes to stream an episode of your favorite tv sitcom. It’s the fastest-known orbit for this kind of binary star system, where a rapidly spinning, very dense star called a pulsar pulls material away from a lighter companion star. In this visualization you can see that the two stars in this system are closer to each other than Earth is to the Moon! Scientists were able to confirm the new record using our Neutron star Interior Composition Explorer aboard the International Space Station (@国際宇宙ステーション). Credit: @NASA
