Have you guys heard about this one ?
Gaia observatory link link 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%." You can also read about it here http://www.spaceflightnow.com/news/n0407/06mapping/ http://en.wikipedia.org/wiki/Gaia_probe or check the European space site |

One of the more entertaining ESA products to come out of the Gaia release is this newly posted YouTube video showing how the Orion constellation will evolve over time:
Orion from now till 450000 AD No corrections made for Betelgeuse possibly blowing up (whose timing is unknown in any event). Also notice the Hyades star cluster moving in. Another earlier YouTube from ESA showed an approximation for the whole sky for five million years. Future of Two Million Stars Recommend going full screen on both of these. |
