    What happens when you crash into a comet? That was a question considered by astronomers when they designed the Deep Impact mission, launched in January. On July 4, the Deep Impact spaceship will reach its target, Comet Tempel 1, and fire an impactor at its surface, photographing the result. The remaining crater may tell how Tempel 1 is constructed. If, for example, the comet is an extremely loose pile of debris, the impactor may leave little or no discernable crater. But if the comet's surface is relatively firm, the impactor's ripple may leave quite a large crater. Pictured above is an artist's impression of the initial encounter between the spacecraft and the comet.

    Why did South Korea's rocket launch fail?

    South Korean officials said they did not know where to pin blame, but noted the explosion occurred in the Russian-made first-stage of the rocket rather than in the Korean-made second stage. The failure of the South Korea rocket launch was an embarrassing setback.

  • In Pictures Don't Fear the Leaper: A world of frogs

    The American bullfrog, named for its loud, deep mating call, eats insects, fish, birds, snakes, baby turtles, and other frogs. Bullfrogs are native to the eastern U.S., but they have been released west of the Rocky Mountains where they have devastated local populations of frogs and other small animals. The eight species in this slideshow are among the 18 species frogs from around the world on display at the exhibit 'Frogs: A Chorus of Colors,' which runs at the Museum of Science, Boston, from February 13 through May 25.
