There have been no significant changes in the past thousand years. There have been many solar events though, such as a recent Total Solar Eclipse, where the the galaxy aligned. It happens around once ever 300,000 years or so.
You have to understand that the Universe has taken around 14 billion years to get to where it is today, changes in thousands of years are very minuscule and gradual.

Do the constellation patterns ever change?
No, the pattern of stars that make up a constellation does not change. However, the positions of the stars relative to Earth may change due to Earth's rotation and orbit. Over thousands of years, the positions of stars in constellations may drift slightly.
Why does the light we see from stars take thousands of years to reach us?
The light we see from stars takes thousands of years to reach us because stars are located incredibly far away from Earth, often measuring their distances in light-years, which is the distance light travels in one year. For instance, if a star is 1,000 light-years away, the light we see today actually left that star 1,000 years ago. Thus, we are observing the past state of the star rather than its current condition. The vast distances in space and the finite speed of light (approximately 299,792 kilometers per second) contribute to this delay.
How early did they navigate the stars?
Human navigation of the stars dates back thousands of years, with evidence of early star maps and celestial navigation tools found in ancient cultures such as the Babylonians, Egyptians, and Greeks. The use of stars for navigation allowed early civilizations to travel long distances by land and sea.
What is cepheus's distance from earth?
'Cepheus' is the name of a constellation in the northern sky ... a pattern formed ofseveral stars and defined by human observers. There is no actual connection orrelationship among its several stars, and they're all at different distances from us.
Why astronomers have difficulty looking at distant stars except?
Astronomers have difficulty looking at distant stars because while we have highly specialized telescopes, they are in constant contention with various other celestial bodies. In addition to this, the light of distant stars takes hundreds of thousands of years to reach us, making it impossible to get a current look at a distant star.
What has happened to Earth's magnetosphere over the thousands of years?
The Earth's magnetosphere has flipped. It is the opposite as it was thousands of years of go.
How long have stars been known?
Since the first man as on earth. Stars have been known for thousands of years!
How long does the lion constellation live?
Constellations like Leo, which represents a lion, do not have a lifespan as they are simply groupings of stars in the sky. These stars have varying lifespans ranging from millions to billions of years. The pattern they form in the sky can be seen for thousands of years as long as the stars themselves are visible.
Is the Stonehenge a landmark?
Because of its unique association with the Sun and the Stars built thousands and thousands years ago by the mysterious pagan Druids.
Why is the Stonehenge a landmark?
Because of its unique association with the Sun and the Stars built thousands and thousands years ago by the mysterious pagan Druids.
Who form the Grand Canyon?
Erosion, it happened probably over thousands of years
Why are the stars that you see in the sky now how they looked like thousands of years ago?
The light from stars takes a long time to reach us due to their immense distance from Earth. When we observe a star in the sky now, we are seeing the light that was emitted by that star thousands of years ago. This is because the speed of light is finite and the universe is vast.
How old is the constellation Leo?
The constellation Leo is not a living entity with a specific age. It is a pattern of stars that has been identified and named by different ancient civilizations, with its origins dating back thousands of years.
Who was the first person to use glue?
That happened thousands of years ago, There is no record of a name.
What if science never happened?
We'd still be using trial & error - as we did for thousands of years.
What factors led to the agricultural revolution?
No factories. The agricultural revolution happened thousands of years before machines.
Why don't the stars appear to move with respect to one another?
They are so far away - the closest stars are tens of thousands, or hundreds of thousands, times farther than the planets - that any movement would take years to be noticeable.
