Hubble Pinpoints Distant Supernovae

An American Astronomical Society Meeting Release

January 8, 1998: Peering halfway across the universe to analyze light from exploded stars that died long before our Sun even existed, the Hubble telescope has allowed astronomers to determine that the expansion of the cosmos has not slowed since the initial impetus of the Big Bang. Thus, the universe's expansion should continue to balloon outward indefinitely.

These results are based on unprecedented distance measurements to supernovae that are so far away they allow astronomers to determine if the universe was expanding at a faster rate long ago. These images showcase three of the supernovae used in the survey. The arrows in the bottom row of pictures pinpoint these exploding stars; the top row of images shows the regions where the supernovae reside.
