Sigma Octantis; although it lies roughly 1 degree off from the actual South Pole Location. Astronomers recently located a very faint nebula (only seen through special filters) which lies much closer to the actual South Pole.
At the south pole.
To see both the north celestial pole and the south celestial pole at the same time a person would need to standing at the equator. The atmospheric haze may interfere near the horizon may obstruct the view.
The celestial pole is the point in the sky directly above the Earth's North or South Pole. The North Celestial Pole is located near the North Star (Polaris), while the South Celestial Pole does not have a bright star near it. Stars appear to rotate around these points due to Earth's rotation.
No. Argenrtina is entirely south of the equator, so the north celestial pole is not visible.
The Celestial Poles are the infinite extension of the North and South Poles from the Earth into space. The North Star or Polaris, is within 1 degree of the North Celestial Pole. There is no equivalent star for the South Celestial Pole.
The stellar south pole is located in the constellation Octans. This constellation is relatively faint and is situated in the southern celestial hemisphere. The south celestial pole itself is not associated with any bright stars, but Octans contains the star Sigma Octantis, which is the closest star to the south celestial pole.
While there is a star which is, entirely coincidentally, pretty close to the North Celestial Pole, there is no corresponding star near the South Celestial Pole.
A person would have to visit the equator for the celestial equator to pass through your zenith or one would have to be at the south pole for the south celestial pole to be at your zenith. You would not see this, but you could note it.
The celestial pole is directly above Earth's geographic poles, so to place a celestial pole at your zenith you would need to be at either the North Pole or the South Pole. At these locations, the celestial pole would be directly overhead, making it appear as if the axis of Earth's rotation extended into the sky.
SOUTH
Currently, the Earth's south pole is pointing towards the constellation of Octans. This constellation is not very well-known, but it is used for celestial navigation as it helps determine the location of the south celestial pole.
The north and south celestial poles are two imaginary points and therefore cannot be "discovered".
