What are 2 major discoveries made by William Herschel in the 18th century?
William Herschel was possibly the greatest astronomer of the 18th Century. He made many discoveries including the finding of Uranus. But his biggest claim to fame was his ability to build telescopes.

Who discovered infrared rays?
astronomer Sir William Herschel
Most encyclopedias and physics books credit the great British astronomer Sir William Herschel with the discovery of infrared radiation in 1800.
How did William Herschel Discover Uranus?
The planet Uranus was discovered by William Herschel on March 13, 1781. He discoverd Uranus while surveying stars in the night sky using a telescope that he had built himself. Herschel noticed that one of these “stars” seemed different, and after observing it many more times, noticed that it orbited the Sun.
What did Sir William Herschel discover in 1858?
The German-born English astronomer William Herschel discovers Uranus, the seventh planet from the sun. Herschel, who was later knighted for his historic discovery, named the planet Georgium Sidus, or the “Georgian Planet,” in honor of King George III of England.
What is William Herschel famous for?
William Herschel was one of the first ‘professional’ astronomers, and discovered infrared radiation. His sister Caroline helped him to develop the modern mathematical approach to astronomy. William, son of a musician, was born in Hanover, Germany, in 1738.
When was the first telescope made?
1608
The invention of the telescope Historians are not absolutely sure who invented the telescope, but it is known that in 1608 a Dutch spectacle maker, Hans Lipperhey, announced a new lens-based seeing instrument that made distant objects appear much closer.
Why Galileo invented the telescope?
Galileo invented an improved telescope that let him observe and describe the moons of Jupiter, the rings of Saturn, the phases of Venus, sunspots and the rugged lunar surface. His flair for self-promotion earned him powerful friends among Italy’s ruling elite and enemies among the Catholic Church’s leaders.
Where is the William Herschel Telescope located in Spain?
The William Herschel Telescope ( WHT) is a 4.20-metre (165 in) optical / near-infrared reflecting telescope located at the Observatorio del Roque de los Muchachos on the island of La Palma in the Canary Islands, Spain. The telescope, which is named after William Herschel, is part of the Isaac Newton Group of Telescopes.
When did Thomas Herschel discover the double star?
Herschel constructed his first large telescope in 1774, after which he spent nine years carrying out sky surveys to investigate double stars. Herschel published catalogues of nebulae in 1802 (2,500 objects) and in 1820 (5,000 objects).
How did William Herschel become famous as an astronomer?
This was the first planet to be discovered since antiquity, and Herschel became famous overnight. As a result of this discovery, George III appointed him Court Astronomer. He was elected as a Fellow of the Royal Society and grants were provided for the construction of new telescopes.
When did Herschel publish his catalogue of nebulae?
Herschel published catalogues of nebulae in 1802 (2,500 objects) and in 1820 (5,000 objects). The resolving power of the Herschel telescopes revealed that many objects called nebulae in the Messier catalogue were actually clusters of stars. On 13 March 1781 while making observations he made note of a new object in the constellation of Gemini.
