The Cosmic Background Explorer satellite produces a detailed map of the background radiation remaining from the Big Bang. The map shows "ripples", caused by slight variations in the density of the early universe – the seeds of galaxies and galaxy clusters. The 10-meter Keck telescope on Mauna Kea, Hawaii, is completed. The first revolutionary ...

By historical astronomy we include the history of astronomy; what has come to be known as archaeoastronomy; and the application of historical records to modern astrophysical problems." Historical and ancient observations are used to track theoretically long term trends, such as eclipse patterns and the velocity of nebular clouds.
The Sydney 'Star Camera' used in the Carte du Ciel project, original publication, 1892. The Carte du Ciel (French pronunciation: [kaʁt dy sjɛl]; literally, 'Map of the Sky') and the Astrographic Catalogue (or Astrographic Chart) were two distinct but connected components of a massive international astronomical project, initiated in the late 19th century, to catalogue and map the positions of ...
