Astronomy and space exploration

July 16 – July 22 – The fragments of Comet Shoemaker-Levy 9 impact the planet Jupiter
July 21 – R. Ibata, M. Irwin, and G. Gilmore discover the Sagittarius Dwarf Elliptical Galaxy, a satellite galaxy of the Milky Way. It was considered the closest galaxy to the Milky Way from its discovery until 2003.[1]
October 12 – NASA lost contact with the Magellan spacecraft after a successful mission. The probe crashed into Venus shortly after.
Asteroid 7484 Dogo Onsesn is discovered by Masahiro Koishikawa.
14032 Mego is discovered.
8C 1435+63 is discovered and at z=4.25 becomes the most distant known galaxy.[2][3]


March 31 – The journal Nature reports the finding in Ethiopia of the first complete Australopithecus afarensis skull, significant in the study of human evolution.


September 10 – Wollemia (the 'Wollemi Pine'), previously known only from fossils, is discovered living in remote rainforest gorges in the Wollemi National Park of New South Wales by David Noble.[4]
The Dingiso or tree-kangaroo of Western New Guinea is first seen by scientists.[5]
Flora of China begins publication.


November 9 – Darmstadtium first detected at the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany, by Peter Armbruster and Gottfried Münzenberg, under the direction of Prof. Sigurd Hofmann.[6]
December 8 – The first three atoms of Roentgenium are observed by an international team led by Sigurd Hofmann at the GSI in Darmstadt.[7]


October – First public demonstration of the Cochrane Database of Systematic Reviews.[8]
December 15 – Publication of the "Fukuda" clinical description of chronic fatigue syndrome.[9]

Molecular biology

Green fluorescent protein is successfully expressed in C. elegans, starting its career as a fluorescent marker.


May 6 – The Channel Tunnel, which took 15,000 workers over seven years to complete, opens between England and France. It is now possible to travel between the two countries in 35 minutes.


January 25 – Stephen Cole Kleene (b. 1909), mathematician.
July 29 – Dorothy Crowfoot Hodgkin (b. 1910), chemist.
August 19 – Linus Pauling (b. 1901), American chemist.
