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.
2007 – First light at Gran Telescopio de Canarias (GTC), in Spain, the largest optical telescope in the world with an effective diameter of 10.4 meters. 2021 — James Webb Space Telescope (JWST) , was launched 25 December 2021 on an ESA Ariane 5 rocket from Kourou, French Guiana and will succeed the Hubble Space Telescope as NASA's flagship ...
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 ...
Hebrews 10 is the tenth chapter of the Epistle to the Hebrews in the New Testament of the Christian Bible.The author is anonymous, although the internal reference to "our brother Timothy" (Hebrews 13:23) causes a traditional attribution to Paul, but this attribution has been disputed since the second century and there is no decisive evidence for the authorship.
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 history of the Dearborn Observatory coincides with the founding of the Chicago Astronomical Society in 1862. [4] The society heard of the 1861 construction of a 469.9 millimetres (18.50 in) lens for a telescope, which made it, at the time, the largest refracting telescope in the world.
NASA's James Webb Space Telescope is by far the most powerful observatory ever launched into space.. Even Webb's very first images show why NASA spent 25 years and $10 billion. The Hubble Space ...
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.
