    Astronomy is expensive and high-tech. And so to prioritize which big-ticket tools should be funded in the next decade, astronomers have come up with a wish list.

    Professional astronomers and amateurs alike scan the sky continuously, looking for new, undiscovered objects. But in 1997 they spectacularly missed a comet tearing through the solar system, says a team that recorded the comet with a camera aboard the Solar and Heliospheric Observatory (SOHO).

    Astronomers have for the first time discovered a dwarf galaxy that has a spiral structure, like our own Milky Way, albeit much smaller and fainter. Until now, dwarf galaxies seemed to lack such spirals. The unexpected find may shed light on the origin and evolution of dwarf galaxies.

    A strange star has flared up in a galaxy 25 million light-years from Earth and may soon become too dim to study. As a result, astronomers around the world are madly probing the mysterious object.

    LONG BEACH, CALIFORNIA--The "Oh-My-God" particle is not a fluke or experimental error.

    After successfully sweeping up the first particles ever captured from a stream of interstellar dust, the Stardust spacecraft today safely stored its microscopic treasures. It's now zooming toward a January 2004 encounter with Comet Wild-2.

    In a world of uncertainty, Einstein said, you can always count on the speed of light. Now a rigorous test of gamma rays from space shows that Einstein was right--at least to 20 decimal places.

    For months cosmologists have been eagerly awaiting measurements of the edge of the universe gathered by an antarctic balloon.

    For astronomers who work on the Mauna Kea telescopes in Hawaii, the trip is no junket: It takes a day or more of flying and a 2-hour ride on treacherous roads to reach the chilly 4200-meter summit, where they sometimes battle altitude sickness. Their hardship travel may soon become less common.

    MOUNTAIN VIEW, CALIFORNIA--Biochemists would love to divine the birthplaces of amino acids, the basic components of proteins.

    Scientists have discovered a new way to spot solar flares erupting on the far side of the sun. The technique, reported in the 1 May Geophysical Research Letters, might one day forecast the storms of particles that occasionally disrupt Earth's satellites.

    The older they get, the more Hollywood's stars tend to keep their age secret. In the universe, it's the other way around. Astronomers have the most trouble determining the age of young stars. But now, a team has found that an alcohol test may give them away.

    The "glowing eye" of planetary nebula NGC 6751, captured by the Hubble Space Telescope, offers a preview of our own sun 6 billion years hence.

    Gamma ray scientists are losing observing time on another orbiting observatory. Last month, NASA announced it would destroy the 10-year-old Compton Gamma Ray Observatory due to faulty gyroscopes (Science, 31 March, p.

    Cancer research and sending humans to Mars may seem light-years apart, but technological advances have put them on the same flight path.

    To the surprise of many astronomers, Andromeda has been dethroned as the heftiest galaxy in the Local Group, our immediate neighborhood in the universe, which contains some 30 galaxies.

    Sometimes all a detective needs to crack a case is a stroke of good luck--like finding a fingerprint in the right place. Research is no different.

    Although the sun seems perfectly smooth from Earth, its surface is roiled by huge eruptions. A few times each day these eruptions spew out charged particles as coronal mass ejections (CME); these can disrupt radio communications when they hit Earth's magnetic field.

    Four years ago, the spacecraft Ulysses hit a strange smooth patch in its bumpy ride through the solar wind. At the same time, its detectors were suddenly peppered with an unexpected spray of ionized particles, like the windshield of a car speeding through a swarm of bugs.

    NASA is reorganizing its Mars exploration effort in the wake of a critical report released Tuesday. The report identifies some of the mistakes that led to last year's loss of an orbiter and a lander.

    The older a galaxy, the heavier the black hole at its center, according to a study slated for publication in the 1 April Monthly Notices of the Royal Astronomical Society.
