Stars change over time as they consume their nuclear fuel, causing them to evolve in different ways depending on their initial mass. Young stars fuse hydrogen into helium in their cores, then progress to heavier elements like carbon and oxygen. Some stars end their lives as white dwarfs, neutron stars, or black holes, while others may go through explosive events like supernovae.

How do the stars locations change over time?
All the stars and the Sun are moving through space in different directions and at different speeds. Over long times (to a person) they change their positions in the sky and the constellations change.
Do constellations change over time?
Yes, constellations appear to change positions in the sky over time due to the phenomenon known as precession. This is caused by the slow wobbling of the Earth's axis, altering our perspective of the stars' positions in the sky over thousands of years. So while the constellations themselves are fixed patterns of stars, their apparent positions from Earth do change over long periods.
Why have the number of stars changed?
The number of stars in a galaxy can change due to the birth and death of stars, as well as interactions with other galaxies like mergers and collisions. Additionally, new stars can form from the gas and dust present in galaxies, contributing to changes in the total number of stars over time.
Do constellations change shape?
No, constellations do not change shape. They are patterns of stars in the sky that have been identified and named by astronomers. However, the positions of the stars in the sky may change over time due to the Earth's rotation and orbit around the Sun, but the overall shape of the constellation remains the same.
How did the universe change over time?
The universe has evolved over billions of years through processes like the Big Bang, expansion, formation of galaxies and stars, and the eventual emergence of planets and life. This ongoing change is driven by physical laws governing the interactions of matter and energy.

Why do stars change position?
Stars appear to change position in the night sky due to Earth's rotation. As the Earth moves, different stars come into view while others become hidden below the horizon. This apparent motion is also influenced by the Earth's orbit around the Sun, causing the stars to shift gradually over time.
