The Big Dipper image excerpt form Wikipedia
“in order for things to change some things, must appear to remain the same” Carlogero Cangelosi 2010
When we gaze at the night sky we see little change in the way the surrounding stars appear.
We notice the changing phases of the moon the movements of the planets, but everything else in the night sky seems to remain the same year after year.
Mariners old and new sure knew their stuff. Since ancient times the stars have remained a constant in our night skies. Although the stars, in our Solar System are all moving, and still the stars from our perspective change very little over the centuries.
No doubt the Southern Cross as will the big dipper and all constellations will change there shape in time to come.
The stars move in relation to each other, their movement is very small. Any movement is nearly imperceptible during a person’s lifetime, but they add up over millennia.
This means that in, say, 10,000 years, many common constellations will have a very different shape to what they have now, the night sky will appear vastly different.
Its all a matter of perception when we now see the constellations we can relate to their shape and position in space.
Everything in the universe is moving over time the same stars in the constellations will change so will our perception here on earth over the next ten thousands years.
I have made some simulations in relation to how the Southern Cross will look like in say 10,000 years time.
I have taken two recognizeable constellations one from the northern hemisphere and one Southern hemisphere. Crux the cross and Ursa Major ( the Big Bear) also called the big dipper the plough.
southern cross constellation the image on the left is how the southern Cross looks like now the image on the right is what the southern cross will look like in 10,000 years time
Ursa Major ( Big Dipper) the image on the left is as it looks now the image on the right is what it will look like in 50,000 years time
All things change; nothing perishes. "I am always doing that which I can not do, in order that I may learn how to do it". Pablo Picasso ...
