    Every so often, the stream of particles coming from the sun knocks out a satellite or disrupts power grids on Earth. But that's nothing compared to the collisions in interstellar space, where the solar wind bangs into a huge particle cloud.

    Never have so many astronomers been so eager to claim they can't see straight. Groups working with three different telescopes have detected weak lensing, a distortion of distant galaxies that reveals the dark matter strewn across space.

    Somewhere in the universe a trio of stars could be orbiting in a way Isaac Newton never dreamed of. Mathematicians have discovered a new choreography in which three stars trace out a figure eight. Like dancers in a Scottish reel, each star passes between the other two in turn.

    Mars researchers have debated for years whether the planet once hosted a massive ocean. Now a team of geophysicists may have found a missing link in the growing body of evidence that a major ocean did exist.

    The far side of the sun seems inaccessible, obscured from our view by 1.4 million kilometers of hot, seething gas. But because the sun rotates every 27 days, that hidden face emerges without fail to shine upon us and, at times, launch dangerous storms our way.

    NASA is forging ahead with a $75 million mission to watch the whole Earth from space following the release of a favorable report 8 March.

    Managers of NASA's Mars exploration program are bracing for a potentially devastating report about the failure of two Mars spacecraft last year and the future direction of the effort.

    It's a hat dance on a galactic scale: The spectacular Sombrero galaxy has been caught mid-swirl by a Chilean telescope. The spiral galaxy, about 50 million light-years away, is almost directly edge-on from our point of view. Like other spiral galaxies, its center bulges with older stars.

    WASHINGTON, D.C.--Researchers have discovered what causes the dark, mostly straight streaks that adorn the plains of Mars.

  • 18 Feb 2000

    The Hubble Space Telescope has taken a close-up look at a strange event in the aftermath of a supernova: the sudden brightening of a huge gas ring that circles the exploding star. Astronomers think the ring is flaring up as it is smashed by debris from the immense explosion.

    WASHINGTON, D.C.--The asteroid Eros has taken a heavier beating in its lifetime than expected, but it appears to have remained intact, scientists told a press conference here today.

  • 16 Feb 2000

    The most popular theory about how the moon formed--as a result of an apocalyptic collision between Earth and another object--always seemed to have a fatal flaw: It couldn't explain the moon's strange, tilted orbit. Now, planetary scientists say that may not be a problem at all.

    Wondering what to get the stargazer who has everything? For just $3000, the University of Arizona will put your loved one's name on a mirror of the Large Binocular Telescope (LBT), now under construction on Mt. Graham, Arizona.

    After roaming the solar system for 4 years in pursuit of the asteroid Eros, the Near Earth Asteroid Rendezvous (NEAR) spacecraft this morning slipped into orbit around the largest of the near-Earth asteroids.

    Jupiter's weather is awesome but frustratingly mysterious. Meteorologists have wondered what drives the planet's weather engine: the feeble sunlight that bathes the jovian clouds, or heat seeping out from deep inside the planet.

    Walk into a parking garage or a bar and you'll probably inhale a ubiquitous pollutant called polycyclic aromatic hydrocarbons, or PAHs. Made up of two or more fused benzene rings, they turn up in cigarette smoke, car exhaust, or just about anywhere hydrocarbons burn.
