Artist's impression time-lapse of distant supernovae (fulldome)

In this much speeded-up artist's impression showing a collection of distant galaxies, the occasional supernova can be seen. Each of these exploding stars briefly rivals the brightness of its host galaxy. One class of supernovae, Type Ia, which result from thermonuclear runaway explosions on white dwarf stars in binary systems, have been used to map out the expansion rate of the Universe.
