Final answer:
The North Celestial Pole and the South Celestial Pole can be seen at different times depending on your location on Earth, but they are never visible simultaneously.
Step-by-step explanation:
The North Celestial Pole and the South Celestial Pole are points in the sky that correspond to the Earth's axis of rotation. The North Celestial Pole is located in the direction of the star Polaris, and the South Celestial Pole is located in the direction of the Southern Cross constellation. Since the Earth rotates on its axis, these poles are only visible at different times depending on your location on Earth.
From the Equator, the North Celestial Pole is on the Northern Horizon, and the South Celestial Pole is on the Southern Horizon. This means that they can be seen at different times, but never at the same time from this location.
So, the answer to your question is that there is nowhere on Earth where you can see both the North Celestial Pole and the South Celestial Pole at the same time. They are visible at different times everywhere, but never simultaneously.
