Type Ia supernovae are thought to be potentially the most dangerous if they occur close enough to the Earth.

Type Ia supernovas happen when a white dwarf star is orbiting a big star.

How is a nova different from a Type Ia supernova?

The use of Type Ia supernovae is crucial in determining the correct cosmological model.

Type Ia supernovae are some of the best ways to determine extragalactic distances.

Its spectrum indicates that it is a typical Type Ia supernova.

Type Ia supernovae release tremendous energy, in which the light produced is often brighter than an entire galaxy of stars.

As expected for the remnant of a Type Ia supernova, no associated neutron star or black hole has been found.

White dwarf stars, if they have a near companion, may then become Type Ia supernovae.

Type Ia supernovae all explode with nearly the same amount of energy and therefore have almost the same intrinsic brightness.
