NOVA's Runaway Universe site is the companion Web site to the television program of the same name, which followed the efforts of two rival teams of astronomers as they search for exploding stars, map out gigantic cosmic patterns of galaxies, and grapple with the ultimate question: What is the fate of the universe? Visitors of the site will find an interactive timeline of the universe, learn what happens during a supernova explosion, take a virtual tour of the universe, learn how the Doppler effect is used to determine a stellar objects speed, and several other cool interactive and educational activities. This unique and quite interesting site is well worth exploring, although an adequate modem and computer are needed to fully appreciate what it has to offer.
