This is a timeline of Jodrell Bank Observatory.

1930s

• 1939 — Jodrell Bank site purchased by the University of Manchester as a botany field station.^[1]

1940s

• 1960, May — Lord Nuffield pays the remaining debt on the Mark I and the observatory is renamed the Nuffield Radio Astronomy Laboratories.^[11]
• 1962 — As part of a radio-linked interferometer, the Mark I identifies a new class of compact radio sources, later recognised as quasars.^[12]
• 1962 — Jodrell Bank radio telescope is mentioned in the science fiction novel A for Andromeda by Fred Hoyle and John Elliot.
• 1964 — The Mark II telescope is completed.^[13]
• 1966 — The Mark I receives pictures from Luna 9, the first spacecraft to make a soft landing on the Moon.^[14]
• 1966 — The Mark III telescope is completed.^[15]
• 1968 — The Mark I confirms the existence of pulsars.^[16]
• 1968 — The Mark I took part in the first transatlantic VLBI experiment in 1968, with other telescopes being those at Algonquin and Penticton in Canada.^[17]
• 1969 — The Mark I is used for the first time in a VLBI observation, with the Arecibo radio telescope in 1969.^[12]

1970s

• 1970–1971 — The Mark I is repaired and upgraded; it is renamed to the Mark IA.^[15]
• 1972–1973 — The Mark I carries out a survey of radio sources; amongst these sources was the first gravitational lens, which was confirmed optically in 1979.^[18]
• 1976, January — storms bring winds of around 90 mph which almost destroy the telescope. Bracing girders are added.^[19]

1980s

• 1980 — The Mark IA is used as part of the new MERLIN array.^[12]
• 1982 — The 42 ft telescope is built, to replace the 50 ft.^{[citation needed]}
• 1986 — The first pulsar in a globular cluster is discovered.^[12]
• 1986 — The Mark II telescope is given a new surface that is accurate to 1/3 mm.^[13]
• 1987 — The Mark IA is renamed the Lovell Telescope after Bernard Lovell.^[20]

1990s

• 1990 — The new 32 m Cambridge telescope at Mullard Radio Astronomy Observatory is added to the MERLIN array.^[12]
• 1992 — The MERLIN array becomes a national facility.^[12]
• 1993 — At the request of NASA, the Lovell Telescope searches for the Mars Observer spacecraft.^[21]
• 1998 — The Lovell Telescope begins participation with the SETI Project Phoenix^[22][23]

• 2000–2002 — The Lovell Telescope is resurfaced, increasing its sensitivity at 5 GHz by a factor of five.^{[citation needed]}
• 2003, December — The Lovell Telescope searches for the Beagle 2 lander on Mars.^{[citation needed]}
• 2004, January — Astronomers from Jodrell Bank, Australia, Italy and the U.S. discover the first known double pulsar.^{[citation needed]}
• 2004 — Minor scenes for the film of the Hitchhiker's Guide to the Galaxy are filmed at Jodrell Bank.^{[citation needed]}
• 2005, February — Astronomers using the Lovell Telescope discovered a galaxy that appears to be made almost entirely of dark matter.^[25]
• 2005, March — Jodrell Bank becomes the centre of the World's largest scale model of the Solar System as part of the Spaced Out project.^[26]
• 2006, September — Jodrell Bank wins the BBC's online competition to find the UK's greatest "Unsung Landmark".^[21]
