  • New dwarf planet in the Oort cloud changes picture of solar system

    New dwarf planet in the Oort cloud changes picture of solar system
    Astronomers searching for the faintest glimmers of light beyond distant Pluto say they’ve discovered a new dwarf planet – and that this planetoid’s movements hint that an invisible giant planet perhaps 10 times the size of Earth could be...
  • Comet ISON is see-through, and that's not good

    Comet ISON is see-through, and that's not good
    Did Comet ISON survive its brush with the sun? Four days after the comet made its closest approach to our nearest star, the scientific consensus is "probably not." Yes, something did survive ISON's harrowing Thanksgiving Day encounter with the sun. (See...
  • 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...

     Concern grows over possibility of a massive power surge
    FREDERICK, Md. — Roscoe Bartlett was rattling off the prices of giant bags of rice, wheat and corn, sold cheaply at Sam's Club. The former congressman from rural, western Maryland expressed bewilderment that every American doesn't stockpile such...
  • 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...
  • On Saturn's moon Titan, scientists catch waves in methane lakes

    On Saturn's moon Titan, scientists catch waves in methane lakes
    Now that spring is here, maybe it's time to grab your surfboard and head to some far-off coastline -- perhaps as far as the outer solar system. Scientists using NASA's Cassini spacecraft have found hints of waves sloshing on Titan, Saturn’s...
  • 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....
  • Suburban teachers picked for NASA astronomy program

    Trailing Christopher Columbus and a total eclipse in the Atlantic
    MÁLAGA, Spain — When I was 8 years old, I wanted to run away to sea and be a cabin boy on a clipper ship. Sixty years later — gender, age and vocation notwithstanding — I finally got the chance. As I packed to meet the Star Flyer on...
  • 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...
  • Astronomers fooled by shiny, but tiny, black hole

    Astronomers fooled by shiny, but tiny, black hole
    A bright black hole in the Pinwheel galaxy has been shining us on, astronomers say – this intergalactic trickster puts out light like a big black hole but it’s really quite tiny. M 101 ULX-1, described in the journal Nature, may force...
