  • Titan: Land o' methane lakes

    Titan: Land o' methane lakes
    New images captured by NASA's Cassini spacecraft reveal a land of liquid methane and ethane lakes spotting the north pole of Titan, Saturn's largest moon. NASA's Jet Propulsion Laboratory in La Cañada Flintridge released the new images this week, saying...
  • Water geysers erupt on Europa! Could Jupiter's icy moon host life?

    Water geysers erupt on Europa! Could Jupiter's icy moon host life?
    Jupiter’s icy moon Europa squirts water like a squishy bath toy when it’s squeezed by the gas giant’s gravity, scientists say. Using NASA’s Hubble Space Telescope, they caught two 124-mile-tall geysers of water vapor spewing out...
  • 2014 stargazing calendar: Catch three eclipses, new meteor shower

    2014 stargazing calendar: Catch three eclipses, new meteor shower
    Unique celestial events in 2014 include two full lunar eclipses visible from Maryland and a partial solar eclipse that will begin just before sunset one October afternoon. A new meteor shower could be a bonus. Here’s what stargazers have to look...
  • Milky Way may host billions of Earth-size planets

    There's no place like home, but scientists now say that Earth-size planets orbiting sun-like stars in a so-called habitable zone are so common that there could be as many as 11 billion in the Milky Way alone. Using a clever method to detect Earth-size...
  • 28 solar flares in the last seven days, and more may be coming

    28 solar flares in the last seven days, and more may be coming
    The sun has erupted more than two dozen times over the last week, sending radiation and solar material hurtling through space - and scientists say more eruptions may be coming. This shouldn't be unusual. After all, we are technically at solar maximum,...
  • Kepler-78b: This scorched planet is more like Earth than you think

    Kepler-78b: This scorched planet is more like Earth than you think
    Astronomers have discovered a world that is incredibly close to Earth-sized and may also be made of rock and iron, like our own planet. The only problem? It’s a scorched hellscape of molten lava that sits less than a million miles from its star&...
  • 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...
  • 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 from  outside our solar system in a quarter-century. The groundbreaking discovery made beneath the ice of Antarctica opens a whole new window...
  • A postcard from Voyager 1, interstellar traveler

    A postcard from Voyager 1, interstellar traveler
    You can’t spot Voyager 1 as it leaves the solar system’s heliosphere, but the National Radio Astronomy Observatory can, and did it just for kicks. Well maybe not for kicks, but scientists were interested in how well their array of 10 radio...
  • Asteroid the length of 3 football fields eludes sky-watchers

    Asteroid the length of 3 football fields eludes sky-watchers
    An asteroid the length of three football fields has eluded astronomers once again. "If we see it, that will be historic because we've reacquired a potentially hazardous asteroid," astronomer Bob Berman said Monday night. "If it turns out we can't see...
  • Concern grows over possibility of a massive power surge

     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...
