  • ALMA telescope spies a planetary system in process of being born

    ALMA telescope spies a planetary system in process of being born
    With amazing clarity, astronomers have spied a solar system in the act of being born. At the center is HL Tau, an infant star that is believed to be no more than 1 million years old. It is surrounded by hazy, concentric rings of material that scientists...
  • As many as half of all stars reside outside of galaxies, study finds

    As many as half of all stars reside outside of galaxies, study finds
    Even stars can get lost in space. Scientists who shot a rocket up beyond Earth’s atmosphere for a matter of minutes have made a remarkable discovery about the diffuse background light that permeates the universe: As many as half of all stars may...
  • Martin L. Perl dies at 87; Nobel winner discovered tau lepton

    Martin L. Perl dies at 87; Nobel winner discovered tau lepton
    Long before he would be awarded a Nobel Prize, Martin L. Perl liked to do his own plumbing repairs. He usually had spare time, and he clearly knew the physics, his oldest son, Jed, recalled. And Martin Perl was, first and foremost, a hands-on...
  • Fireball in space: Astronomers capture images of a star going nova

    Fireball in space: Astronomers capture images of a star going nova
    You don’t see this every day. For the first time, astronomers have captured images of a nova very soon after the stellar explosion flared into existence and have tracked the fireball's dramatic expansion into space. The discovery, described in the...
  • Solar eclipse brings observers to Mt. Wilson

    Solar eclipse brings observers to Mt. Wilson
    To mark the solar eclipse that swept across the Southern California sky on Thursday — the first one seen in Los Angeles in 2 1/2 years — the Cosmic Cafe on Mt. Wilson was serving up sandwiches and chili. This was kind of a big deal. After...
  • Chicago to see partial solar eclipse Thursday

    Chicago to see partial solar eclipse Thursday
    Attention stargazers: Thursday afternoon's sunset will coincide with a partial solar eclipse. That means the sun — when spied through eclipse glasses or other special viewing devices — will appear crescent-shaped. "It's a dramatic event,"...
  • 'Blood moon' eclipse graces pre-dawn skies

    'Blood moon' eclipse graces pre-dawn skies
    Chicago and much of the country were treated to its second total lunar eclipse of the year just before dawn Wednesday. At 4:18 a.m., the moon slipped into the Earth’s shadow and continued to darken into a total eclipse from 5:27 a.m. until 6:22 a....

    Enthusiasts land at JPL
    More than 45,000 science fans took advantage of a free offer to explore the inner workings of NASA’s Jet Propulsion Laboratory last weekend when the La CaƱada facility opened its doors for its annual Open House. The event, which attracts large...
  • The 'cyberwar' against cancer gets a boost

    The 'cyberwar' against cancer gets a boost
    Tel Aviv — Two years ago, Prof. Eshel Ben-Jacob of Tel Aviv University's School of Physics and Astronomy and Rice University's Center for Theoretical Biological Physics made the startling discovery that cancer, like an enemy hacker in cyberspace,...
  • Leaky galaxy is a star factory that could shed light on early universe

    Leaky galaxy is a star factory that could shed light on early universe
    Astronomers searching for hints of leaky galaxies have picked up radiation from a star-forming galaxy in the nearby universe that behaves rather like some of the earliest stellar factories that gave a dark universe its first rays of light. The galaxy...
  • How to end an argument

    How to end an argument
    Two hundred and thirty years ago, Charles Marie de la Condamine returned to France with proof about the shape of the Earth after spending 10 years in Latin America. For thousands of years, human beings had roamed the planet indifferent to its form until...
