      Light Pollution Veils Starry Skies

      (Newser) - Dark skies are being engulfed by light all over the world, creating some unexpected consequences, the Wall Street Journal reports. Over two-thirds of the world's people— including nearly all Americans—can no longer see "what is possibly the most extraordinary natural wonder," said one astronomer. The amount of artificial light worldwide has tripled since 1970, and is suspected of causing some cancers. More »

      Stargazers Witness Birth of Supernova

      (Newser) - A  pair of Princeton astronomers have become the first people ever to witness the explosive death of a star, Space.com reports. The pair were observing another supernova in its later stages when they happened to spot a huge burst of X-rays 90 million light years away. Astronomers believe their observations will fill in some blanks in knowledge about this cosmic phenomenon. More »

    • Youngest Supernova Discovered

      National Geographic  |  May 15, 08 3:55 AM CDT

      Youngest Supernova Discovered

      (Newser) - Scientists have discovered the remains of the youngest exploding star, or supernova, ever seen in the Milky Way, shedding new light on the life cycles of stars. The baby supernova G1.9+0.3 is a mere 140 years old, reports National Geographic . Supernovas are a vital component of galaxy development because the exploding stars disperse high-energy particles and minerals, fueling the creation of new stars. More »

      Black Hole Smashes Record

      (Newser) - A newly discovered stellar-mass black hole shatters the weight record for holes formed from dying stars—and defies explanation by current theories. Faced with its mysterious heft,  astrophysicists can only conclude that stellar-mass black holes "can be much larger than we had realized," Space.com reports. More »

    • Orion Nebula Closer to Us

      Discovery Channel  |  Oct 11, 07 9:12 PM CDT

      Orion Nebula Closer to Us

      (Newser) - The famed Orion Nebula is the closest stellar nursery to Earth, and it's even nearer than scientists previously thought, a study finds. Researchers had pinned it at about 1,565 light years away 25 years ago, but using multiple telescope shots to create a "virtual telescope" as wide as the Earth itself reveals it's 10 to 20% closer. Those numbers are already being refined, Discovery Channel reports. More »

      Google Takes Map Program to the Stars

      (Newser) - Launching off of the success of Google Earth, Google launched a new program today allowing armchair astronomers to chuck the telescope and gaze at the heavens from their monitors. Google Sky will harness Hubble photos along with a database of information, and feature more than one million stars and 200 million galaxies, the BBC reports. More »

      Dying Star Unlocks Life Cycle Mystery

      (Newser) - Astronomers have recently spotted a dying red giant star trailing material knocked off by winds  created by its high-speed orbit, providing an important clue to the life cycle of stars. Scientists have long theorized that the detritus of old stars become the seeds for new ones, but they've never before seen the process. More »

      Comet Dust Will Light Sky

      (Newser) - Comet debris will light up the sky tomorrow night and Monday morning with shooting stars as Earth passes through the Perseid meteor shower. For the best view, pick a dark spot away from city lights and look east, says the Discovery Channel. "It's going to be a great show," a NASA expert advises. The showers will start around 9 PM EDT tomorrow night and peak at 2 AM Monday morning. More »

      Most Massive Star Ever Weighs In

      (Newser) - The most massive star yet discovered has been "weighed," astronomers say, and it tips the scales at a whopping 114 times the mass of the sun. The enormous star forms the bigger half of a rapidly orbiting binary system and it far outstrips both its companion star and the previous record holder—which weigh in at 84 and 83 solar masses, respectively.

      Hubble Finds Dark Matter

      (Newser) - Astronomers have discovered a ring of dark matter in a galaxy cluster about 5 billion light years away. The Hubble Telescope turned up an anomaly in the way stars in the area appear, which researchers think is a distortion caused by the intense gravity of the galactic "glue" holding the cluster together.
