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.).
Vulpecula / v ʌ l ˈ p ɛ k j ʊ l ə / is a faint constellation in the northern sky. Its name is Latin for "little fox", although it is commonly known simply as the fox.It was identified in the seventeenth century, and is located in the middle of the Summer Triangle (an asterism consisting of the bright stars Deneb, Vega, and Altair).
The constellation Lacerta as it can be seen by the naked eye. Lacerta is typical of Milky Way constellations: no bright galaxies, nor globular clusters, but instead open clusters, for example NGC 7243, the faint planetary nebula IC 5217 and quite a few double stars. It also contains the prototypic blazar BL Lacertae. Lacerta contains no Messier ...
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
The next explosion is expected to occur from now through September. “The star system, normally magnitude +10, which is far too dim to see with the unaided eye, will jump to magnitude +2 during ...
IAU designated constellations in equirectangular projection (epoch B1875.0) In contemporary astronomy, 88 constellations are recognized by the International Astronomical Union (IAU). [1] Each constellation is a region of the sky bordered by arcs of right ascension and declination, together covering the entire celestial sphere. Their boundaries ...
Caelum / ˈ s iː l əm / is a faint constellation in the southern sky, introduced in the 1750s by Nicolas Louis de Lacaille and counted among the 88 modern constellations.Its name means "chisel" in Latin, and it was formerly known as Caelum Sculptorium ("Engraver's Chisel"); it is a rare word, unrelated to the far more common Latin caelum, meaning "sky", "heaven", or "atmosphere".

Because of precession, the positions of the constellations slowly change over time. By comparing the positions of the 41 constellations against the grid circles, an accurate determination can be made of the epoch when the original observations were performed. Based upon this information, the constellations were catalogued at 125 ± 55 BC.
