The ultimate Hollywood disaster movie would portray the catastrophic consequences of a nearby supernova eruption. If one were to occur within 1,000 light-years of Earth, it would be the end of civilization as we presently enjoy. A supernova eruption closer than 100 light-years from Earth would bring devastating health consequences for human beings.
Supernovae are the final titanic explosions of stars with initial masses that exceed 9 times the Sun’s mass. At peak brightness, a single supernova can outshine 100 billion ordinary stars.
A supernova outshining its host galaxy, NGC 4526.
