This movie shows the evolution of a star 10 times more massive than our sun. The blue color of the star’s surface visible in the first frame is the result of this higher mass. Each star spends most of its life in a phase known as the main sequence, during which it burns hydrogen into

Binary systems are star systems comprising two stars orbiting around their common center of mass in a Keplerian orbit, which means that the two components are bound together by their mutual gravitational attraction. In this image, the binary system consists of a main sequence star like our sun, and a neutron star 1.4 times more
