Have you guys heard about this one ?

Gaia observatory

QUOTE
"The satellite will determine the position, colour and true motion of one thousand million stars and over 100,000 objects in our Solar System. Gaia will also identify as many as 10,000 planets around other stars. "
QUOTE
"Gaia will measure distance (from parallax) out to ~100,000 parsecs; for stars ~10,000 pc away, with a Vmag of ~<15, Gaia will measure their distances accurate to ~10-20%."

GAIA is going through shakedown -- testing and calibration. (That's supposed to last until May, I gather.) So they just posted a first test image: http://www.esa.int/Our_Activities/Space_Sc...omes_into_focus. Apparently there won't be a lot of these, since making images isn't what GAIA is about.

is the equivalent image from Hubble; I'm guessing they're using NGC1818 as a calibration target because it has the very distinct red and blue star series that you can see in the Hubble shot
