The year 1984 in science and technology involved some significant events.

Astronomy and space exploration

• February 7 – Astronauts Bruce McCandless II and Robert L. Stewart make the first untethered space walk.
• The National Radio Astronomy Observatory in the United States converts the 36-foot radio telescope on Kitt Peak (originally built in 1967) to the ARO 12m Radio Telescope.

Biology

• First known case of Bovine spongiform encephalopathy, in England.^[1]
• The enzyme telomerase is discovered by Carol W. Greider and Elizabeth Blackburn in the ciliate Tetrahymena.^[2]
