NASA astronomers may have found a way to take more precise measurements of the distances between galaxies. Currently, astronomers use a certain type of supernova, known as a Type la supernova, to gauge the distances between galaxies and from this, the rate at which the universe is expanding. The reason that this particular breed of supernova is singled out for this purpose, is that when they explode, they give out a very similar amount of light...
