    Few doubted that they were out there, but it sure is good to have confirmation: For the first time, astronomers have watched a planet in another star system cross the face of its parent star, proving conclusively that extrasolar planets exist.

    The stream of science data from the Hubble Space Telescope stopped last weekend after the fourth of the instrument's six gyroscopes failed. The $2 billion telescope will remain in a "safe mode" until astronauts arrive next month for a scheduled service mission to the orbiting spacecraft.

    In 1916, Albert Einstein predicted that violent cosmic motions should send gravitational waves rippling through the fabric of space. Today, researchers inaugurate an unusual observatory designed to catch those elusive waves.

    Scientists have long speculated that Mars is the most likely place in the solar system to find life outside our cozy planet.

  • 10 Nov 1999

    A balloon-borne telescope has taken the closest look yet at ripples in the microwave glow that pervades the sky and holds clues to the shape and makeup of the universe. Earlier microwave studies had suggested that the fabric of space-time in the universe is flat rather than curved.

    WASHINGTON, D.C.--The loss of the Mars Climate Orbiter (MCO) spacecraft in September, when the unwitting use of English units during mission navigation sent the craft plummeting into the martian atmosphere, reflects the failure of mission team members to fully follow

    After a long battle with cancer, Jan van Paradijs, an astrophysicist with joint appointments at the University of Amsterdam, the Netherlands, and the University of Alabama in Huntsville, died yesterday morning at the age of 53.

  • 29 Oct 1999

    Astronomers have caught their first-ever glimpse of the funnel that channels a fountain of subatomic particles, erupting from the center of a galaxy, into a narrow stream thousands of light-years long.

  • 22 Oct 1999

    Ernst Öpik, an Estonian astronomer whose wide-ranging work on meteors led to the development of heat shields for spacecraft, was born on 23 October 1893. Öpik studied the erosion of meteors as they plunge through an atmosphere.

    HUNTSVILLE, ALABAMA--It may sound like a feeble joke, but astronomers say they have discovered a new kind of gamma ray burst: one without gamma rays.

  • 13 Oct 1999

    ABANO TERME, ITALY--Despite crippling budgetary shortfalls, Russia's planetary exploration program is hoping to get at least one mission off the ground in the next few years.

  • 7 Oct 1999

    Asteroids wreak global havoc only once every 100,000 years or so--contrary to what tabloid headlines might suggest.

  • 5 Oct 1999

    If an ocean once lapped at the rusty shores and cliffs of Mars, it left no clear traces of an ancient coastline on the planet's surface. That's the story told by new images from the Mars Global Surveyor spacecraft, currently orbiting the Red Planet.

  • 1 Oct 1999

    The first comet to be discovered by telescope was spotted 152 years ago today

  • 30 Sep 1999

    Astronomers think they have spotted the celestial powerhouses that generate the mysterious blasts of radiation known as gamma ray bursts.

  • 30 Sep 1999

    NASA officials today cast blame for the loss of the Mars Climate Orbiter on a misunderstanding over which units--English or metric--were being used to fine-tune the spacecraft's trajectory.

  • 28 Sep 1999

    Astrophysicists have taken a new and detailed look at the blazing heart of the Crab Nebula, the remnants of a star that exploded into view nearly 1000 years ago.

  • 23 Sep 1999

    Early this morning, engineers at the Jet Propulsion Laboratory (JPL) in Pasadena, California, were stunned to discover that the Mars Climate Orbiter (MCO) spacecraft, presumably entering orbit for a 2-year mission to study martian weather, had dipped too far into the atmosphere on its arrival and

    NAPLES, ITALY--Small organizations usually resist being subsumed into a larger one.

  • 13 Sep 1999

    A telescope high in the Chilean Andes has opened a clear view of a long-sought hump in measurements of the universe's faint background radiation.

  • 8 Sep 1999

    TUCSON, ARIZONA--Two cosmologies have collided on telescope-dense Mount Hopkins south of here--and the loser for now appears to be the Smithsonian Institution. Last week the U.S.

  • 7 Sep 1999

    Astronomers have photographed what could be MACHOs (massive compact halo objects)--hypothetical dark objects whose gravity could help explain the motions of the galaxy's visible stars.

  • 26 Aug 1999

    Only 5 weeks have passed since Chandra, NASA's new x-ray observatory, was launched, and already it may have found the youngest known neutron star--the corpse of a dead star--in the Milky Way.

  • 25 Aug 1999

    The view is nothing special at the landing site of the Mars Polar Lander, but scientists hope the geology will make up for it.

  • 25 Aug 1999

    A discovery by Australian scientists will force astronomers to rethink their models of pulsars, tiny stars that fling radio beams into the universe as they spin.
