Oh darling, those stars aren't running marathons, they just look like they're moving because of Earth's rotation on its axis. So technically, it's the spinning Earth show that makes it seem like the stars are doing the salsa in the sky all night long. Sweet dreams, stargazer!
What else can I help you with?
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.
Why are telescopes placed in space above earths atmosphere?
Scintillation. Our atmosphere is in continous motion. Warm air changes the angle of EM waves passing through a little bit differently than cold air. The constant motion causes constant shifts in the waves. This is why the stars seem to twinkle. In space, there is no such distortion. Space borne telecopes see far clearer images because of this.
What is the Celestial globe?
Celestial globes show the apparent positions of the stars in the sky. They omit the Sun, the Moon and planets because the positions of these bodies vary relative to those of the stars, but the ecliptic, along which the Sun moves, is indicated.
Describe how gravity causes stars to form galaxies?
It depends on how much gravity that causes stars to form. It depends on how big the star in the galaxies is.
Was used to take bearings from the sun or stars to plot the ships positions on a map?
yes
A shows the positions of stars in the sky?
A star chart shows the stars positions in the night sky.
Why the moon stars and sun appear to change positions in the sky?
The sun and stars change positions because Earth moves
Why does the moon stars and planets change position during a night?
The moon, stars, and planets appear to change position in the night sky due to the rotation of the Earth. As the Earth turns on its axis, different celestial objects become visible while others move out of sight. This causes the constant changing of positions of celestial bodies as seen from our perspective on Earth.

What has happened to the pattern of stars over the last thousands of years?
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.
Why does positions of stars change with the season?
Because it orbits
What are the names of the stars and their positions in the southern cross?

What cause changes in the light coming from distant stars and galaxies?
The apparent redshift is caused by the Doppler Effect; the frequency of waves is increased by an approaching source and decreased by a leaving source. Since the fgrequencies we see from stars are slightly lower than they should be, we know that the stars and other objects are moving away. The Doppler Effect causes changes of light emanating from distant stars and galaxies.
What is astrometry?
measuring the positions of stars on the sky
What shows Positions of the stars in the sky?
Both a star map and a planetarium.
