A constellation is an area on the celestial sphere in which a group of visible stars forms a perceived pattern or outline, typically representing an animal, mythological subject, or inanimate object. [1] The first constellations were likely defined in prehistory. People used them to relate stories of their beliefs, experiences, creation, and ...
They were the first to record a supernova, in the Astrological Annals of the Houhanshu in 185 AD. Also, the supernova that created the Crab Nebula in 1054 is an example of a "guest star" observed by Chinese astronomers, although it was not recorded by their European contemporaries. Ancient astronomical records of phenomena like supernovae and ...
The USSR launches its first space station Salyut 1 into orbit. It is followed by a series of stations, culminating with Mir in 1986. A permanent platform in orbit allows cosmonauts to carry out serious research and to set a series of new duration records for spaceflight.
A star chart drawn 5000 years ago by the Indians in Kashmir, which also depict a supernova for the first time in human history. [7] The Nebra sky disk , a 30 cm wide bronze disk dated to 1600 BC, bears gold symbols generally interpreted as a sun or full moon, a lunar crescent, several stars including the Pleiades cluster and possibly the Milky Way.
2022 — James Webb Space Telescope (JWST) releases the Webb's First Deep Field. 2022 — JWST detects CEERS-93316, a candidate high-redshift galaxy, with an estimated redshift of approximately z = 16.7, corresponding to 235.8 million years [45] after the Big Bang. [46] If confirmed, it is one of the earliest and most distant known galaxies ...
Their boundaries were officially adopted by the International Astronomical Union in 1928 and published in 1930. [2] The ancient Mesopotamians and later the Greeks established most of the northern constellations in international use today, listed by the Roman-Egyptian astronomer Ptolemy. The constellations along the ecliptic are called the ...
The Farnese Atlas, a Roman copy which dates to AD 150, is the oldest surviving pictorial record of Western constellations and is now at the National Archaeological Museum in Naples, Italy. The position of the constellations on the sphere's equinox have been used to date the design of the original Greek sphere to 370 BCE.
These constellations form the basis for the modern constellations that were formally adopted by the International Astronomical Union in 1922, with official boundaries that were agreed in 1928. Of the stars in the catalogue, 108 (just over 10%) were classified by Ptolemy as 'unformed', by which he meant lying outside the recognized constellation ...
