The ESA space telescope GAIA has lifted off from Kourou atop a Soyuz-Fregat Russian rocket. Its mission, if successful. is to map the Milky Way in 3d taking data on about a billion stars. I can barely image the computing power needed to analyze that mass of data. GAIA@home anyone? Tullio Edit. Separation of GAIA from Soyuz-Fregat accomplished. It should reach the L2 Lagrange point in about one month. Edit again. Data will reach 1 petabyte and the mission duration is 5 years. |

This is a first rate scientific mission and could give also results in fields that were not present at the time of its design such as eso-planets and dark matter. One scientist at the press conference in Italy said that he expects the unexpected. Tullio |

Gaia will observe 1% of all the stars in our galaxy, allowing astronomers to determine its origin and evolution http://www.theguardian.com/science/2013/dec/19/gaia-space-telescope-launches-milky-way-galaxy edit |

update.. Was out Galaxy formed from a black hole?? A new breakthrough using data from the Gaia-ESO project provides new insight into our Milky Way galaxy. It supports the fact that the galaxy might have formed the inside-out with the inner region forming faster than the outer reaches. http://www.utahpeoplespost.com/2014/01/new-gaia-observations-reveal-the-galaxy-is-formed-inside-out/ |

I see stars! The billion-star surveyor Gaia's test image of the is "coming into focus." Once routine measurements begin Gaia will provide a staggering amount of information about the galaxy, including "a dense cluster of stars in the Large Magellanic Cloud," a European Space Agency news release reported. http://www.hngn.com/articles/23851/20140206/gaias-billion-star-survey-brings-milky-way-into-focus-with-test-image-video.htm |
