  • Kepler's comeback? New K2 mission could chase wilder targets

    Kepler's comeback? New K2 mission could chase wilder targets
    Don't call it a comeback just yet. Astronomers mourned the Kepler Space Telescope after it was crippled last year. But NASA’s planet hunter may be getting a second chance at life — with an ingenious, just-so-crazy-it-might-work plan that would...
  • Bruce C. Murray dies at 81; former director of JPL

    Although most of his fellow space scientists scoffed at the idea, Jet Propulsion Laboratory scientist Bruce C. Murray insisted that a picture of a planet's surface was worth a thousand words — or at least as much as the measurements of magnetic...
  • 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...
  • LUX Dark matter detector finds no WIMPs, so why are scientists happy?

    LUX Dark matter detector finds no WIMPs, so why are scientists happy?
    Scientists at an ambitious dark matter experiment in operation at an underground gold mine in South Dakota have discovered exactly what they thought they would: nothing. And the results have got them really excited. After running the detector for...
  • NASA confirms Voyager 1 has left the solar system

    NASA confirms Voyager 1 has left the solar system
    After 36 years of space travel and months of heated debate among scientists, NASA confirmed Thursday that Voyager 1 has indeed left our solar system and had entered interstellar space more than a year ago. "Voyager has boldly gone where no probe has...
  • Google doodle: Maria Mitchell, first pro female astronomer in U.S.

    Google doodle: Maria Mitchell, first pro female astronomer in U.S.
    Today’s Google Doodle honors a 19th century woman whose name has been stamped across the heavens -- Maria Mitchell, America’s first professional female astronomer. Today would have been her 195th birthday. Mitchell was born in Nantucket to a...
  • 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...
  • Y2K-like glitch thought responsible for Deep Impact's demise

    Y2K-like glitch thought responsible for Deep Impact's demise
    Once a week, scientists at the University of Maryland, College Park and NASA aimed satellites across the solar system to where they figured the spacecraft known as Deep Impact would have drifted since seven days earlier. They would ping it for its...
  • Hopkins APL scientists launching massive balloon to study comet

    Hopkins APL scientists launching massive balloon to study comet
    Scientists from the Johns Hopkins University Applied Physics Laboratory are set to launch a massive balloon above the skies of New Mexico this weekend for a glimpse of Comet ISON, the rare comet on its way to looping past the sun and Earth in the coming...
  • Little star or big planet? Dim brown dwarfs illuminate the difference

    Little star or big planet? Dim brown dwarfs illuminate the difference
    Is it time for a stellar identity crisis? Astronomers studying cold brown dwarfs have found that the boundary between star and planet might be much blurrier than once thought. These strange 'failed' stars, described online in the journal Science,...
