    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 Cañada facility opened its doors for its annual Open House. The event, which attracts large...
  • Asteroid Named After Retired Western Connecticut Professor

    Asteroid Named After Retired Western Connecticut Professor
    Dr. Phillip Lu is characteristically self-deprecating about the news that a newly discovered asteroid has been named after him. "My younger daughter asked, 'Dad, what's this supposed to mean?'" said Lu, 82, a retired astronomy professor from Western...
  • 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...
  • 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...
  • 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...
  • 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...
  • 'Cosmos' recap: From Alexandria to dark matter

    'Cosmos' recap: From Alexandria to dark matter
    "Cosmos" wrapped its 13-episode run this week by emphasizing the importance of knowledge and critical thinking by way of the scientific method in "Unafraid of the Dark." Despite a few missteps here and there, host Neil de Grasse has taken us on a...
  • Two X-class solar flares in less than 2 hours, and more may come soon

    Two X-class solar flares in less than 2 hours, and more may come soon
    The sun unleashed two X-class solar flares in the span of one hour and 10 minutes Tuesday morning, and there is a good chance that more may be coming soon. Solar flares are big bursts of radiation that come from dark areas of the sun called sunspots. An...
  • Scientists smash crystals to determine the true age of the moon

    Scientists smash crystals to determine the true age of the moon
    The violent impact that created our moon may have occurred millions of years earlier than previously thought, according to new research. Mounting evidence suggests that the moon came into being after the Earth got slammed by a Mars-sized object named...
  • 'Magic Island' may show Titan's oceans are hardly pacific

    'Magic Island' may show Titan's oceans are hardly pacific
    The sudden disappearance of a bright spot on a methane sea on Titan could add more proof that Saturn’s largest moon is a lot like Earth – just colder and gasier. Astronomers at Cornell University were flipping between radar images of...
  • Hopkins scientists pursue origins of the universe

    Hopkins scientists pursue origins of the universe
    Johns Hopkins University scientists are building a telescope meant to look at space in a way no one has before, hoping to probe the blackness between planets, stars and galaxies, into deep time and the mystery of how it all began. For decades,...
