The first star catalogue in Greek astronomy was created by aristillus in approximately 300 BC, with the help of Timocharis.
The star catalog
of Hipparchus (2nd century BC) included 1020 stars
and was used to assemble Ptolemy's
star catalogue. Hipparchus is
known for the discovery of the first recorded nova (new star). Many of the constellations and star
names in use today derive from Greek astronomy.
In spite of the apparent
immutability of the heavens, Chinese
astronomers were aware that new
stars could appear. In 185 AD,
they were the first to observe and write about a supernova, now known as the SN 185.
The brightest stellar event in recorded history was the SN 1006 supernova, which was observed in 1006
and written about by the Egyptian astronomer Ali ibn Ridwan and several Chinese astronomers.
The SN
1054 supernova, which gave birth
to the Crab Nebula, was also
observed by Chinese and Islamic astronomers.
