  • NASA's Dawn satellite has reached the asteroid belt. First stop: Vesta.

    Vesta and Ceres, the two largest objects in the asteroid belt, have mystified scientists for centuries. With NASA satellite Dawn on final approach to Vesta, the wait is almost over.

  • Hidden sea on a Saturn moon? New evidence says yes.

    Satellite Cassini flew through geyser plumes spouting from Enceladus and gathered ice crystals. These crystals are salt-rich, suggesting that a hidden salty sea lurks beneath Enceladus's icy cap.

  • How Mercury is like Saturn (and other surprises from NASA's orbiter)

    NASA's Messenger craft has been orbiting Mercury for 88 days. Among its findings: a Saturn-like magnetic field, high concentrations of sulfur, and some support for the notion there is water ice in shadowed craters.

  • End of the world May 21st? About a billion years too soon, astronomers say.

    Beginning of the end of the world: May 21st is what a California minister (with a considerable following) predicts. Scientists, for their part, consider the sun's 'habitable zone' in calculating when Earth will become toast.

  • What's new with Titan? Five intriguing findings about Saturn's moon

    Like many a robotic planetary mission, you've gotta love the Cassini-Huygens mission to Saturn – a joint effort between NASA and the European Space Agency. It launched in 1997 and for the past six years (yes, it took some time to get there), Cassini has been the gift that keeps on giving. Saturn's largest moon, Titan, continues to be one of Cassini's most intriguing targets. It's the only planetary satellite with a thick atmosphere – a hydrocarbon haze that makes a smoggy day in Los Angeles look crystal clear by comparison. And although it's a cold moon, with lakes of liquid methane, Titan has many of the compounds that on Earth were the building blocks for organic life. It's high on the list of "let's go back" destinations among astrobiologists. So far, Cassdini has performed 73 flybys of Titan, including eight this year. Here are some of this year's eye-popping discoveries associated with Cassini's observations of Titan.
