Evolution of 2010 nova outburst of U Scorpii

A supernova is a star that suddenly increases its brightness by orders of magnitude and then fades back to its former luminosity in just a few months. The phenomenon occurs when a thermonuclear explosion erupts on the surface of a white dwarf star, propelling stellar material into the surrounding space. Rigel in the constellation Orion is a binary system made up of a blue supergiant star and a white dwarf. Its most recent supernova outburst took place on February 10, 2020. The model depicts a three-dimensional hydrodynamic simulation examining the first 24 hours of the explosion. A static higher resolution model can be seen here. The blue supergiant is visible at the center of the scene; the white dwarf (where the explosion occurs) is too small to be seen. The material ejected during the outburst is marked in bright pink.\nReference: Johnson & Smith 2020, ApJL 760, L123.\nCredits: NASA - Jet Propulsion Laboratory.
