NGC 2683 is an unbarred spiral galaxy discovered by William Herschel on 5 February 1788. From 1782 to 1802, and most intensively from 1783 to 1790, Herschel conducted systematic surveys in search of "deep-sky" or non-stellar objects with two 20-foot-focal-length (610 cm), 12-and-18.7-inch-aperture (30 and 47 cm) telescopes (in combination with ...
Sir John Frederick William Herschel, 1st Baronet KH FRS (/ ˈ h ɜːr ʃ əl, ˈ h ɛər-/; [2] 7 March 1792 – 11 May 1871) [1] was an English polymath active as a mathematician, astronomer, chemist, inventor and experimental photographer who invented the blueprint [3] [4] [5] and did botanical work.
In 1781, William Herschel was looking for binary stars in the constellation of Taurus when he observed what he thought was a new comet. Its orbit revealed that it was a new planet, Uranus, the first ever discovered telescopically. [20] Giuseppe Piazzi discovered Ceres in 1801, a small world between Mars and
Although Uranus was the first planet to be discovered by telescope, it is just about visible with the naked eye. Bode consulted older star charts and found numerous examples of the planet's position being given while being mistaken for a star, for example, John Flamsteed, Astronomer Royal in Britain, had listed it in his catalogue of 1690 as a ...

[1] [5] [10] In the subgenre of works visiting multiple locations in the Solar System that appeared throughout the 19th century, Uranus was rarely included, [1] one exception being the anonymously published 1837 novel Journeys into the Moon, Several Planets and the Sun. [2] Early works about Uranus incorrectly envisioned it as a solid planet.
1781 – Charles Messier and his assistant Pierre Méchain publish the first catalogue of 110 nebulae and star clusters, the most prominent deep-sky objects that can easily be observed from Earth's Northern Hemisphere, in order not to be confused with ordinary Solar System's comets. [121] 1787 – Herschel discovers Uranus's moons Titania and ...
When William Herschel discovered Uranus in 1781, he at first named it Georgium Sidus (George's Star) after the King, who later funded the construction and maintenance of Herschel's 1785 40-foot telescope, which at the time was the biggest ever built.
