Supernova 1994D and the Unexpected Universe
Supernova 1994D, seen here as a bright spot in galaxy NGC 4526, was a Type Ia supernova. These explosions are important because they are thought to have a consistent intrinsic brightness. By measuring how bright they appear, astronomers can estimate distances to far-off galaxies, helping to map the universe.
