Two Million Stars on the Move
The Hipparcos and Gaia satellites have provided positional data for two million stars, allowing us to extrapolate their movements over millions of years. Most stars make only small changes in their positions. This video shows how the night sky would change if you could watch it for one million years, beyond local effects from Earth's spin.
