A graphical view of the Cosmic Calendar, featuring the months of the year, days of December, the final minute, and the final second. The Cosmic Calendar is a method to visualize the chronology of the universe, scaling its currently understood age of 13.787 billion years to a single year in order to help intuit it for pedagogical purposes in science education or popular science.
Timeline of stellar astronomy. 1200 BC — Chinese star names appear on oracle bones used for divination. 134 BC — Hipparchus creates the magnitude scale of stellar apparent luminosities; 185 AD — Chinese astronomers become the first to observe a supernova, the SN 185

Ptolemy publishes his star catalogue, listing 48 constellations and endorses the geocentric (Earth-centered) view of the universe. His views go unquestioned for nearly 1500 years in Europe and are passed down to Arabic and medieval European astronomers in his book the Almagest .
The chronology of the universe describes the history and future of the universe according to Big Bang cosmology.. Research published in 2015 estimates the earliest stages of the universe's existence as taking place 13.8 billion years ago, with an uncertainty of around 21 million years at the 68% confidence level.
A list of future observable astronomical events. [1] These are by no means all events, but only the notable or rare ones. In particular, it does not include solar eclipses or lunar eclipses unless otherwise notable, as they are far too numerous to list (see below for articles with lists of all these). Nor does it list astronomical events that ...
Astronomical chronology, or astronomical dating, is a technical method of dating events or artifacts that are associated with astronomical phenomena.Written records of historical events that include descriptions of astronomical phenomena have done much to clarify the chronology of the Ancient Near East; works of art which depict the configuration of the stars and planets and buildings which ...
