A gamma-ray powerhouse's smoking gun? Gas trail points to microquasar jets
In 2016, a binary star system emitting unusually strong gamma rays was discovered in our galactic neighborhood. Now, astronomers have found the smoking gun, or rather, a smoking trail of cool molecular gas that suggests jets emanating from a microquasar—one of the few known outside the Milky Way—are responsible.
