    Dying stars' nebulae mysteriously aligned near galaxy's heart
    Astronomers studying dying stars' colorful cast-offs have discovered a mysterious pattern: Some planetary nebulae in the Milky Way galaxy’s central bulge are strangely aligned, according to a study to be published in Monthly Notices of the Royal...
  • Penumbral lunar eclipse Friday: How you can see it

    On Friday evening, the moon will pass through the hazy outer shadow of the Earth, and if you look carefully, you may be able to see the minor celestial show. The event is called a penumbral eclipse, and, to be fair, it is not especially dramatic. The...

    After nearly nine years in space and 4.7 billion miles traveled, NASA’s Deep Impact spacecraft has met an unexpected end after mission members lost contact with it last month. Though it was unable to complete its latest assignment, the comet-hunting...
  • Earth-like planets may be quite common, relatively close, study says

    Is the Earth a “cosmic freak” or a planetary average Joe around our galactic neighborhood? UC Berkeley astronomer Geoff Marcy says we’re in good company. With some clever sleight of hand, scientists using Kepler data have calculated...

    3 days until comet ISON survives or disintegrates [Photos, video]
    Comet ISON's day of reckoning is nearly upon us. On Thursday -- Thanksgiving Day -- the comet will reach perihelion, its closest approach to the sun. Whether it will survive the blistering heat of this encounter, and the powerful pull of the sun's...
  • Light Pollution Dims View Of Comet, Shrinks Our Horizons

    Comet ISON is barreling toward the center of our solar system, where on Thanksgiving it will slingshot around the sun and head back past Earth. It's already putting on one of the best shows we've had in a while. Astronomers announced Nov. 14 that the...
