Billion dollar observatory will map the Milky Way
Billion dollar observatory will map the Milky Way
http://why.knovel.com/all-engineerin...milky-way.html Gaia, which has been built by space engineering firm Astrium for the European Space Agency, is projected to have a five-year lifespan and is the successor to the ESA's Hipparcos satellite, a data gatherer until its retirement in 1993. The observatory is also expected to add to the information that has been transmitted by the Hubble Space Telescope, with a primary objective being the hunt for exoplanets beyond the borders of the known solar system. |

Similar to the Kepler Space Telescope who's primary objective was also being the hunt for exoplanets beyond the borders of the known solar system. |

Not really, the primary function of this telescope is to find the precise distances and speed of many of the stars in the Milky Way, not exoplanet hunting. Yousuf Khan |

Yousuf Khan True, but with the high precision measurements over an extended period of time, Gaia will be able to find planets by the astrometric method, rather than the doppler or transit methods. The results will be independent of the inclination of the systems. Press officers think that looking for planets is much sexier to the general public. Gaia will be able to map the Milky Way Galaxy to distances of order 10,000 parsecs. Hipparcos was limited by its precision to distances of a few hundred parsecs with any precision. -- Mike Dworetsky (Remove pants sp*mbl*ck to reply) |
