  • Hubble sees 'zombie star' lurking in space: What it is, why it matters

    Hubble sees 'zombie star' lurking in space: What it is, why it matters
    Using the Hubble Space Telescope, researchers have spotted a "zombie star" lurking in deep space. What is this astronomical equivalent of the walking dead, and how did it get there? The story involves a rare type of cosmic explosion, detective work...
  • Rain of asteroids melted early Earth, boiled its oceans, study shows

    Rain of asteroids melted early Earth, boiled its oceans, study shows
    When you look up at the moon’s pockmarked face, you’re actually staring at Earth’s early history. The rain of asteroids that pummeled the lunar surface hit our planet too — it’s just that erosion and plate tectonics blotted...
  • A 'stellar fossil' holds hints of one of the universe's first stars

    A 'stellar fossil' holds hints of one of the universe's first stars
    Astronomers say they’ve discovered the signature of one of the first stars in the universe whose remains were embedded into the body of another very old star. The discovery, described in the journal Science, sheds light on an ancient type of...

    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...
  • Hubble Space Telescope finds clouds on super-Earth, Neptune-sized planets

    Hubble Space Telescope finds clouds on super-Earth, Neptune-sized planets
    Using NASA’s Hubble Space Telescope, two research teams have discovered thick layers of high-altitude clouds covering the atmospheres of two relatively nearby exoplanets: a super-Earth and a "warm Neptune." Scientists are beginning to get a handle...
  • Supernova dust factory seen at last; may explain early galaxy formation

    Supernova dust factory seen at last; may explain early galaxy formation
    Using a powerful radio telescope, scientists have spotted an enormous cloud of dust billowing in the center of a supernova - finally. The discovery, announced at the American Astronomical Society, helps to confirm what scientists have long thought -...
  • Bright ancient galaxies offer rare glimpse of early universe

    A quartet of galaxies spied with NASA's Hubble Space Telescope are among the oldest yet discovered — more than 13 billion years old, born just 500 million years after the big bang. They're also incredibly bright, so luminous that they offer a new...
