NASA Missions Study Shock Waves in Nova Explosion

The video explains the phenomenon of novae, focusing on the 2018 eruption of the star V906 Carinae. It discusses observations from NASA's Fermi mission and other satellites, revealing that novae can emit gamma rays. The process involves a white dwarf pulling material from a companion star, leading to a thermonuclear explosion. Research led by Michigan State University used data from multiple sources to study the event, showing that shock waves from the explosion produce gamma ray and optical flares. These findings help understand more powerful cosmic events.
