This video reveals how our view of the Orion constellation will evolve over the next 450 000 years.
Amid a myriad of drifting stars, the shape of Orion as defined by its brightest stars is slowly rearranged into a new pattern as time goes by.
The portion of the sky depicted in the video measures 40 × 20° – as a comparison, the diameter of the full Moon in the sky is about half a degree.
The video is based on data from ESA's Gaia and Hipparcos satellites, as well as additional information from ground-based observations.
