An interesting subject. If you look into it, all the stars of our constellations reside in our galaxy. As we “know”, our solar system orbits our galactic core. It seems utterly implausible to me that from the earliest recorded observations of the constellations, there has been no change. Orion’s Belt remains Orion’s Belt with the exact same proportions over thousands of years.

Meh maybe the NASA explanation is true but idk those guys sure like to deceive so who knows.
