    Scientists have used more than 2,000 images to create the first long-term study of Titan's weather.

  • Martian methane lasts less than a year

    Updated: 2010-09-22 00:00:00
    Scientists think wind-driven processes can add strong oxidizers to the atmosphere, which could soak up methane more rapidly.

  • LHC experiment observes potentially new and interesting effect

    Updated: 2010-09-21 16:59:06
    This statement was issued on September 21, 2010, by CERN. The original announcement is available here. After almost six months of operation, experiments at the LHC are starting to see signs of potentially new and interesting effects. In results announced by the CMS collaboration today, correlations have been observed between particles produced in [...]

    Scientists believe Phobos may have formed from re-accretion of impact debris.

  • Hot atmosphere of Venus might cool interior of Earth's sister planet

    Updated: 2010-09-21 00:00:00

  • James Webb Space Telescope Testing

    Updated: 2010-09-09 02:52:40
    A model of the James Webb Space Telescope's Mid-InfraRed Instrument will be tested before Christmas at the Rutherford Appleton Laboratory in Oxfordshire, England to ensure the final instrument can see infrared light. Observing the universe in the infrared light portion of the spectrum is important because a number of objects researchers want to observe in space are far too cold to radiate at shorter wavelengths that can be seen as visible light, but they radiate strongly in infrared light........

  • Fifty Times sharper than Hubble

    Updated: 2010-09-09 02:52:39
    M87, the central galaxy of the Virgo cluster in a distance of only 50 million light years, was observed by Yuri Kovalev from the Max Planck Institute for Radio Astronony (MPIfR) in Bonn and colleagues with the VLBA (Very Long Baseline Array) at 2 cm wavelength. The resulting image provides details down to a resolution of one milli-arcsecond, corresponding to a linear resolution of only three light months. The new image of the inner radio jet of M87 shows a highly collimated jet which appears limb-brightened, and also a faint counter-jet. It is unprecedented in its combination of sensitivity and spatial resolution........

Massive dark clouds of gas and dust are silhouetted against the flaming starlight........

  • Cluster makes a shocking discovery

    Updated: 2010-09-09 02:52:36
    ESA's Cluster was in the right place and time to make a shocking discovery. The four spacecraft encountered a shock wave that kept breaking and reforming - predicted only in theory. On 24 January 2001, Cluster's spacecraft observed shock reformation in the Earth's magnetosphere, predicted only in theory, over 20 years ago. Cluster provided the first opportunity ever to observe such an event, the details of which have been published in a paper on 9 March this year........

  • Most Energetic Form Of Light

    Updated: 2010-09-09 02:52:34
    n 2002, when astronomers first detected cosmic gamma rays - the most energetic form of light known - coming from the constellation Cygnus they were surprised and perplexed. The region lacked the extreme electromagnetic fields that they thought were required to produce such energetic rays. But now a team of theoretical physicists propose a mechanism that can explain this mystery and may also help account for another type of cosmic ray, the high-energy nuclei that rain down on Earth in the billions........

  • Radio Peas
