  • New Jupiter-size Planet with a Circular Orbit
    Astronomers announce that a Jupiter-sized planet with a circular orbit has been found for the parent star Tau 1 Gruis. About 100 light years away, the planet is the 102nd found outside our solar system.

  • The Lost World?
    Twists in the Sun's magnetic field create sunspots, and other stars also exhibit these dark, cooler spots on their surfaces. A new study suggests that starspots on the star HD 192263 may be masquerading as an extrasolar planet.

  • Tuning In to Other Worlds
    Some scientists think it may be possible to detect planets beyond our solar system by looking for radio signals generated by same forces that lead to 'Northern Lights'. A team of scientists working on a radio telescope called the Low Frequency Array (LOFAR)

  • Exoplanets
    For a long time, there was a theoretical expectation that other stars have planets, that planets are common. But there was no observational evidence, because it's extremely difficult to see planets of other stars.
