Star trail photography on salt lake in Lut desert in Iran. A star trail is a type of photograph that uses long exposure times to capture diurnal circles, the apparent motion of stars in the night sky due to Earth's rotation. A star-trail photograph shows individual stars as streaks across the image, with longer exposures yielding longer arcs.
Circumpolar star trails in a long-exposure photo of several hours. The stars near the celestial pole leave shorter trails with the long exposure. A circumpolar star is a star that, as viewed from a given latitude on Earth, never sets below the horizon due to its apparent proximity to one of the celestial poles.
Currently, there is no South Pole Star like Polaris, the so-called North Star. Sigma Octantis is the closest near naked-eye star to the south celestial pole, but at apparent magnitude 5.47 it is barely visible on a clear night, making it less useful for casual navigational or astronomy alignment purposes.
The Natchez Trace Trail is not a long, continuous footpath, as is the case with other national scenic trails (such as the Appalachian Trail); rather, only a limited number of trail segments along the route, currently over 60 miles (97 km) [1] of trail, have been developed for hiking and horseback riding.

The President of Chile visits the south pole in January 2025. In 1991, Michael Palin visited the base on the eighth and final episode of his BBC Television documentary, Pole to Pole. [40] [41] On January 10, 1995, NASA, PBS, and NSF collaborated for the first live television broadcast from the South Pole, titled Spaceship South Pole. [42]
The south celestial pole over the Very Large Telescope [3] Locating the south celestial pole. The south celestial pole is visible only from the Southern Hemisphere. It lies in the dim constellation Octans, the Octant. Sigma Octantis is identified as the south pole star, more than one degree away from the pole, but with a magnitude of 5.5 it is ...
At the antipode of this point is the far pole, where Jupiter lies at the nadir; it is also called the anti-Jovian point. There will also be a single unmoving point which is farthest along Io's orbit (best defined as the point most removed from the plane formed by the north-south and near-far axes, on the leading side) – this is the leading pole.
