The Gaia space telescope?

Does anyone know what frequency range the Gaia telescope does its observations in? Visible light, infrared, UV, etc.? If it's visible light then wouldn't that be a problem in observing stars through the galactic dust clouds?

    Gaia uses CCDs, which are visible light plus infrared response down to about 1 micron wavelength.  And yes, some stars behind dense dust clouds will not be observed.  Basically Gaia observes all stars that are brighter than about 20th magnitude in visible light, so a star that is losing a few magnitudes to interstellar dust is still visible to it.  There are 2 billion such stars!

    For once, wikipedia has an excellent article on space research. You can read about Gaia here:

    Infrared is the best Wavelength for looking through Intergalactic Dust Clouds as it shows up signs of heat

    I don't know what the capabilities of that telescope are but they might be listed on NASA or wiki.
