    Default STAR *VEGA *---->Especially for guys interested in astron

    Astronomers announced this week that features observed in the dust swirling around the nearby star Vega may be the signatures of an unseen planet in an eccentric orbit around the star. The report was presented by David Wilner, Matt Holman, Paul Ho and Marc Kuchner of the Harvard-Smithsonian Center for Astrophysics (CfA) in Cambridge, MA to the American Astronomical Society meeting in Washington, DC.

    Vega is the brightest star in the upper left of this 1999 photo of Constellation Lyra.

    Two giant clumps of dust in the ring surrounding Vega may be signatures of an unseen planet orbiting the star in an eccentric orbit. Observations at millimeter wavelengths indicate that infalling dust is trapped in dynamical resonances by the gravitational influence of a planetary body. Such effects may offer an additional method of detecting and studying extrasolar planets to complement radial velocity programs.

    Vega, located 25 light years away in the constellation Lyra, is the brightest star in the summer sky. Observations of Vega in 1983 with the Infrared Astronomy Satellite provided the first evidence for large dust particles around another star, probably debris related to the formation of planets. This discovery likely inspired Carl Sagan to place the alien listening post at Vega in his novel Contact.

    Geetham folks !! if you have interest in astronomy....if you come across the novel by Carl sagan " CONTACT " read it, you will never regret it at all.....
