Map to the Stars
The European Space Agency's Star Mapper is a map of 59,921 stars from the Hipparcos Catalogue. ESA's Hipparcos undertook the first space mission entirely dedicated to astronomy. During its mission Hipparcos measured the position, motion and distance of more than 100,000 stars.
One cool feature of the Star Mapper is the 'Motion' animation. If you select the Motion option you can view an animation of the stars moving across the night sky, in 1,000 year increments. You can also select the rewind button to observe how the stars appeared in the night sky in the past (again in 1,000 year increments).
Star Mapper also allows you to turn on or off the names of stars and the constellations on the map. You can also switch between a stereographic amd 3d map projection.
