The Uranometria contained 48 maps of Ptolemaic constellations, a plate of the southern constellations and two plates showing the entire northern and southern hemispheres in stereographic polar projection. [19] Polish astronomer Johannes Hevelius published his Firmamentum Sobiescianum star atlas posthumously in 1690. It contained 56 large ...
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 International Astronomical Union (IAU) designates 88 constellations. [1] In the table below, they are listed by geographical visibility according to latitude as seen from Earth, as well as the best months for viewing the constellations at 21:00 (9 p.m.).
The two brightest northern stars are Vega and Capella. In the star chart to the right, declination is shown by the radial coordinate, starting at 90° north in the center and decreasing to 30° north at the outer edge. Sidereal hour angle is shown as the angular coordinate, starting at 0° at the left of the chart, and increasing counter-clockwise.
A star chart of the entire Northern Sky, centered on the north celestial pole. The northern celestial hemisphere, also called the Northern Sky, is the northern half of the celestial sphere; that is, it lies north of the celestial equator. This arbitrary sphere appears to rotate westward around a polar axis due to Earth's rotation.
The following lists of constellations are available: IAU designated constellations – a list of the current, or "modern", constellations; Former constellations – a list of former constellations; Chinese constellations – traditional Chinese astronomy constellations; List of Nakshatras – sectors along the Moon's ecliptic
