A series of shots show the rotation of Earth's axis relative to the south celestial pole. The Magellanic Clouds and the Southern Cross are clearly visible. Near the end of the video, the Moon rises and illuminates the scene. The south celestial pole over the Very Large Telescope [3] Locating the south celestial pole
Chart of the southern constellations from declination –40° to the south celestial pole by the Jesuit missionary François Noël published in Acta Eruditorum, 1711.. From the South Pole, in good visibility conditions, the Southern Sky features over 2,000 fixed stars that are easily visible to the naked eye, while about 20,000 to 40,000 with the aided eye.
The Southern Cross constellation functions as an approximate southern pole constellation, by pointing to where a southern pole star would be. At the equator, it is possible to see both Polaris and the Southern Cross. [16] [17] The celestial south pole is moving toward the Southern Cross, which has pointed to the south pole for the last 2000 ...
Projecting a line from γ to α Crucis (the foot of the crucifix) approximately 4 + 1 ⁄ 2 times beyond gives a point close to the Southern Celestial Pole [3] which is also, coincidentally, where intersects a perpendicular line taken southwards from the east–west axis of Alpha Centauri to Beta Centauri, which are stars at an alike ...
In astronomy, the meridian is the great circle passing through the celestial poles, as well as the zenith and nadir of an observer's location. Consequently, it contains also the north and south points on the horizon , and it is perpendicular to the celestial equator and horizon.
Polaris Australis (Sigma Octantis), the southern pole star, is a magnitude 5.4 star just over 1 degree away from the true south celestial pole. Its relative faintness means that it is not practical for navigation. [5] BQ Octantis is a fainter, magnitude 6.82 star located much closer to the South Pole (at less than a degree) than Sigma.
The Southern Celestial Pole migrates through the constellation Carina. Carina is in the southern sky quite near the south celestial pole, making it never set (circumpolar) for most of the southern hemisphere. Due to precession of Earth's axis, by the year 4700 the south celestial pole will be in Carina.
Mensa is a constellation in the Southern Celestial Hemisphere near the south celestial pole, one of fourteen constellations drawn up in the 18th century by French astronomer Nicolas-Louis de Lacaille. Its name is Latin for table, though it originally commemorated Table Mountain and was known as "Mons Mensae".
