A view from the bow-cabin of the starship Sun for 10 Myr: how the sky changed from ancestors of Australopithecus to Homo Sapiens.
I calculated the real galactic orbits of about 11000 stars (all stars that were naked-eye visible at some point in the last 10 million years) and animated them from the Sun's own point of view, following its path through the galaxy.
Full video (available in 4K): [https://youtu.be/i-e8N\_huznE](https://youtu.be/i-e8N_huznE)
Data source: Gaia DR3, complemented with Hipparcos for the brightest stars.
A few things that stood out while making this:
* Star clusters like the Hyades visibly move together as a group between 1.5 and 0.5 Myr ago
* Alpha Centauri (closest star system to us) only becomes visible in the last 500000 years
* Sirius drifts out of Ursa Major and heads toward Orion over time
Caveats: star brightness assumes constant absolute magnitude over time (not accurate for young hot stars), and interstellar dust extinction isn't modeled since no 3D dust map exists for the past.
This is the improved follow-up to a lower-res version I posted few days ago.
