Parallax and Mapping the Stars - ESA Gaia Satellite

ESA have released a beautiful video here showing how parallax (the apparent change in position of an object when viewed from two different locations - varies by range) can be used to measure the locations/distances/orbital paths of different stars and galaxies (not sure how far they go out in this video). The parallax has been greatly exaggerated for display purposes (100000 x times!) and the motion has been sped up one trillion times for the video but well worth a look for anyone working in RS or photogrammetry.
