Benjamin would like to know:No, you cannot. What stars you can see from any part of the world depends on your latitude (how far North or South of the equator you are) For example, where I live, at ~45N latitude, I can never see Alpha Centauri. If I were to take a trip to Hawaii, I would. In Australia, I would be able to see the Southern Cross, but not the Big Dipper.
Is it possible to see the same stars from anywhere in the world?
Can you help?
At any given time ~1/2 of the stars are above the horizon for any place on the Earth. As the Earth rotates, different stars rise and set. However, unless you are on the Equator, there will be some stars that will always be in the sky and never set. How large this part of the sky is depends on how far North or South you are from the Equator . At the North and South Poles, none of the stars in the sky ever rise or set, but just travel in a circle a fixed distance above the Horizon. From anywhere on the equator, you could see any star at one time or another.
