The Night Sky if Earth Lived Somewhere Else in the Galaxy (Simulation)

#space #astronomy #simulation
Same lake, same hour of night. Only Earth's address in the galaxy changes.

0:10 Here, 26,000 light-years from the centre
0:40 Between the galaxies
1:12 100,000 light-years above the disc
1:44 Inside the Orion Nebula
2:16 The core of a globular cluster
2:50 Three light-years from Sagittarius A*
3:35 Here vs the centre

Star counts and brightnesses follow real stellar densities: our neighbourhood (one star per ~300 cubic light-years), a globular-cluster core (~1,000 stars per cubic light-year), the nuclear star cluster around Sagittarius A* (~1,000,000 stars within ten light-years). The galaxy as seen from above the disc and the nebula are artistic renderings guided by those numbers.

Rendered with our own real-time engine. No narration, just music and captions.
