  • IceCube spies unexplained pattern of cosmic rays

    Updated: 2010-07-30 00:00:00

  • Are you the center of the Universe? | Cosmic Variance

    Updated: 2010-07-29 18:27:05
    One topic which generated a lot of discussion at the Gravity and Cosmology meeting was the void model of the Universe. The basic argument is simple: the dark energy is an ugly addition to our cosmological standard model, with 70% of the energy density of the Universe some mysterious substance with weird properties. From a [...]

  • Astronomers find planets in unusually intimate dance around dying star

    Updated: 2010-07-29 00:00:00
    Scientists have uncovered two pairs of planets so close to each other that they interact gravitationally.

  • From early particle accelerators to the LHC in 12 minutes

    Updated: 2010-07-28 23:00:10
    Check out a 12-minute public television program that traces the invention of the cyclotron in Berkeley in the 1930s, the development of SLAC's two-mile-long linear accelerator in the 60s, and how they relate to what's going on at the Large Hadron Collider.

  • Lighting up the dark universe

    Updated: 2010-07-28 19:43:27
    Exploring our dark universe is usually the domain of extreme physics. Clues to dark matter and energy are searched for by huge neutrino telescopes and particle detectors, deep underground, and by experiments launched into space. But an experiment doesn't have to be exotic to explore the unexplained. At the International Conference on High Energy Physics, which ends today in Paris, scientists from the GammeV-CHASE experiment unveiled the first results from their experiment, which used 30 hours' worth of data from a 10-meter-long experiment to place the world's best limits on particles of dark energy.

  • Brilliant star in a colorful neighborhood

    WR 22, a member of a double star system in the Carina Nebula, is shedding its atmosphere at a rate many millions times faster than our Sun.

  • James Webb Space Telescope completes cryogenic mirror test

    Updated: 2010-07-27 00:00:00
    The test gauges how the mirrors change temperature and shape over a range of operational temperatures in space.

  • Massive results for scientists homing in on Higgs boson

    Updated: 2010-07-27 00:00:00
    Scientists have significantly narrowed down the possible mass range of the elusive Higgs boson particle, predicted to exist by the standard model of particle physics.

  • Hyperfast star was booted from Milky Way

    Updated: 2010-07-26 00:00:00
    This is the first direct observation linking a high-flying star to a galactic center origin.

  • NASA's Odyssey spacecraft camera yields most accurate Mars map ever

    Updated: 2010-07-26 00:00:00
    The map was constructed using almost 21,000 images from the Thermal Emission Imaging System, a multiband infrared camera.

  • The Sunflower of Canes Venatici

    Updated: 2010-07-24 00:02:53
    This galaxy is featured in LizPeter’s OOTD for 24th of July 2010. This is Messier 63, though I much prefer its other name, the sunflower galaxy. It’s a wonderful dusty spiral galaxy lying 22.9 million light years away from Earth in the constellation Canes Venatici. It’s one of 7 galaxies bound gravitationally together in the M51 [...]

  • NASA telescope finds elusive buckyballs in space for first time

    Updated: 2010-07-23 00:00:00
    Buckyballs are the largest molecules known to exist in space.

  • Subaru telescope detects clues for understanding the origin of mysterious dark gamma-ray bursts

    Updated: 2010-07-23 00:00:00
    The results open the possibility that dark gamma-ray bursts may spring from high-metallicty environments.

  • Particle physicists collide in Paris

    Updated: 2010-07-22 01:07:35
    Paris’ 17th arrondissement has become particle physics central. More than 1,000 physicists have descended on the Palais de Congrès conference center to attend the 35th International Conference on High Energy Physics, which kicks off today and continues through next Wednesday. ICHEP is the world’s premier particle physics conference, where scientists present and discuss the newest and most intriguing results from experiments in particle physics, particle astrophysics and cosmology, innovative theoretical approaches and predictions, and concepts for future accelerators and particle detectors.

  • Cassini sees moon building giant snowballs in Saturn ring

    Updated: 2010-07-22 00:00:00
    Prometheus' gravitational pull sloshes ring material around, creating wake channels that trigger the formation of objects as large as 12 miles in diameter.

  • Black hole jerked around twice

    Updated: 2010-07-22 00:00:00
    Either a merging of the two central black holes from the colliding galaxies or more gas falling onto the black hole caused the spin axis to jerk around to its present direction.

  • Black Hole Jerked Around Twice

    Updated: 2010-07-21 06:00:00
    This image shows the effects of a giant black hole that has been flipped around twice, causing its spin axis to point in a different direction from before.
