Astronomy and space exploration

January–September – Cosmologists from the Supernova Cosmology Project led by Saul Perlmutter and the High-z Supernova Search Team led by Adam Riess and Brian Schmidt publish evidence that the expansion rate of the universe is increasing.[1][2][3]
January 6 – The Lunar Prospector spacecraft is launched into orbit around the Moon and later finds evidence for frozen water on the moon's surface.
February 26 – Total solar eclipse
March 2 – Data sent from the Galileo spaceprobe indicates that Jupiter's moon Europa has a liquid ocean under a thick crust of ice.
March 5 – NASA announces that the Clementine probe orbiting the Moon has found enough water in polar craters to support a human colony and rocket-fuelling station.

August 22 – Annular solar eclipse
September 6 – Penumbral lunar eclipse
October 29 – Space Shuttle Discovery blasts-off with 77-year old John Glenn on board, making him the oldest person to go into space. He became the first American to orbit Earth on February 20, 1962.
November 20 – Zarya, the first module of the International Space Station, is launched.

Computer science

The first working 2-qubit nuclear magnetic resonance computer is demonstrated at the University of California, Berkeley.


February 4 – An earthquake measuring 6.1 on the Richter Scale in northeast Afghanistan kills more than 5,000.
March 14 – An earthquake measuring 6.9 on the Richter scale hits southeastern Iran.
May 30 – A 6.6 magnitude earthquake hits northern Afghanistan killing up to 5,000.
July 17 – A tsunami triggered by an undersea earthquake destroys 10 villages in Papua New Guinea killing an estimated 1,500, leaving 2,000 more unaccounted for and thousands more homeless.

[edit] Mathematics

Luca Cardelli and Andrew D. Gordon develop ambient calculus.
Thomas Callister Hales (almost certainly) proves the Kepler conjecture.


May 11 & 13 – Nuclear testing: The Pokhran-II: India detonates the five nuclear devices in Pokhran Test Range, an Indian Army base.
May 28 – Nuclear testing: The Chagai-I: In response to India, Pakistan conducts five underground and simultaneous nuclear weapon-testing experiments in the Chagai Hills, thus becoming the first nuclear weapon state in the Muslim world and the seventh in the world.
May 30 – Nuclear testing: The Chagai-II: As part of a tit-for-tat policy, a final plutonium implosion test is carried out in the Kharan Desert.

Physiology and medicine

January 14 – Researchers in Dallas, Texas, present findings about an enzyme that slows aging and cell death (apoptosis).
February 19 – RNA interference first elucidated in C. elegans.
February 28 – Andrew Wakefield publishes a case series (subsequently partially retracted) in The Lancet of twelve children with gastroenterological and autistic spectrum disorders believed to have first presented soon after receipt of the MMR vaccine.[4][5]
July 17 – Biologists report in the journal Science how they sequenced the genome of the bacterium that causes syphilis, Treponema pallidum.
December 11 – Bruce Beutler and colleague publish their discovery that Toll-like receptor 4 functions as a lipopolysaccharide sensing receptor.[6]


April 5 – In Japan, the Akashi-Kaikyo Bridge linking Shikoku with Honshū, at a cost of about US$3.8 billion, opens to traffic, becoming the longest-span suspension bridge in the world.
