  • NASA gets some funding for Mars 2020 rover in federal spending bill

    NASA gets some funding for Mars 2020 rover in federal spending bill
    Congressional negotiators released a $1.1-trillion omnibus spending bill for the 2014 fiscal year that’s more generous to NASA’s scientific endeavors than the White House’s proposal, but it may be too soon to celebrate, officials said...
  • John Dobson dies at 98; former monk developed easy-to-make telescope

    John Dobson, a former monk and self-taught stargazer who developed a powerful, inexpensive telescope that almost anyone could build and showed thousands how to do it during five decades as one of public astronomy's most influential evangelists, has died....
  • Astronomers catch a strand of 'cosmic web' in quasar's bright light

    Astronomers catch a strand of 'cosmic web' in quasar's bright light
    Just as the sun causes a spiderweb’s near-invisible strands to glisten, a brightly shining quasar has lit up what scientists say is a massive filament of the universe’s cosmic web -- making it the first time a fragment of the web has been...
  • Water vapor seen steaming off icy dwarf planet Ceres

    Water vapor seen steaming off icy dwarf planet Ceres
    Before Pluto’s fall from planetary grace, there was Ceres. Depending on your definition, it’s either the largest asteroid or the smallest dwarf planet -- but for a few glorious decades in the 1800s, the rocky sphere was a full planet in the...
  • Supernova blast emitted record burst of gamma rays

    Supernova blast emitted record burst of gamma rays
    Astronomers have chronicled a record-setting burst of gamma rays from the violent death throes of a relatively nearby massive star that imploded into a black hole. The duration of the event -- on the order of hours -- as well as the number of photons...
  • 28 neutrinos from outside the solar system open new era in astronomy

    28 neutrinos from outside the solar system open new era in astronomy
    In a cosmos filled with darkness, scientists say they’ve discovered the first elusive neutrinos to come fromĀ  outside our solar system in a quarter-century. The groundbreaking discovery made beneath the ice of Antarctica opens a whole new window...
  • Scientists detect neutrinos from outside the solar system

    Scientists have detected cosmic neutrinos, elusive subatomic particles that stream through the Earth from outside the solar system, for the first time in 25 years, a feat that could usher in a new era of astronomy. Using technology embedded in a cubic...
  • Rare tiny neutrinos may have huge implications for astronomy

    Together, they contain a tiny fraction of the mass of a single electron. But the 28 neutrinos from deep space detected by an icy observatory beneath the South Pole promise a revolution in the study of the universe, scientists said Thursday. The...
  • Seeking another Earth, by the numbers

    Seeking another Earth, by the numbers
    In a room with concrete block walls from which he can barely see the sky, Drake Deming explores the heavens. Several days a week he can be found in his office at the University of Maryland, College Park, surrounded by three computer screens, analyzing...
  • 3 days until comet ISON survives or disintegrates [Photos, video]

    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...
