1917 – Mount Wilson 100-inch (2.5 m) optical reflecting telescope begins operation, located in Mount Wilson, California; 1918 – 1.8m Plaskett Telescope begins operation at the Dominion Astrophysical Observatory, Victoria, British Columbia, Canada; 1919 – International Astronomical Union (IAU) founded
1672 — Laurent Cassegrain, produces a design for a reflecting telescope using a paraboloid primary mirror and a hyperboloid secondary mirror. The design, named 'Cassegrain', is still used in astronomical telescopes used in observatories in 2006. 1674 — Robert Hooke produces a reflecting telescope based on the Gregorian design.
Notes on Hans Lippershey's unsuccessful telescope patent in 1608. The first record of a telescope comes from the Netherlands in 1608. It is in a patent filed by Middelburg spectacle-maker Hans Lippershey with the States General of the Netherlands on 2 October 1608 for his instrument "for seeing things far away as if they were nearby." [12] A few weeks later another Dutch instrument-maker ...
The 10-meter Keck telescope on Mauna Kea, Hawaii, is completed. The first revolutionary new wave of telescopes, the Keck's main mirror is made of 36 six-sided segments, with computers to control their alignment. New optical telescopes also make use of interferometry – improving resolution by combining images from separate telescopes.

The James Webb Space Telescope (JWST) is an international 21st-century space observatory that was launched on 25 December 2021. [1] [2] It is intended to be the premier observatory of the 2020s, combining the largest mirror yet on a near-infrared space telescope with a suite of technologically advanced instruments from around the world.

2005 – Spitzer Space Telescope data confirm what had been considered likely since the early 1990s from radio telescope data, i.e., that the Milky Way Galaxy is a barred spiral galaxy. [14] [15] 2012 – Astronomers report the discovery of the most distant dwarf galaxy yet found, approximately 10 billion light-years away. [16]
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
