The First Map To Show Uranus
Nice example of Bode's diagram of the planets orbiting the sun.
Bode's map is the first to illustrate Uranus, after its discovery by Friedrich Wilhelm Herschel.
Frederick William Herschel
Frederick William Herschel, (1738 – 1822) was a German-born British astronomer, composer and brother of fellow astronomer Caroline Herschel, with whom he worked. Born in the Electorate of Hanover, Herschel followed his father into the Military Band of Hanover, before migrating to Great Britain in 1757.
Herschel constructed his first large telescope in 1774, after which he spent nine years carrying out sky surveys to investigate double stars. The resolving power of the Herschel telescopes revealed that the nebulae in the Messier catalogue were clusters of stars. Herschel published catalogues of nebulae in 1802 (2,500 objects) and in 1820 (5,000 objects). On March 13, 1781, he realized that one celestial body he had observed was not a star, but a planet, Uranus. 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.
Herschel pioneered the use of astronomical spectrophotometry as a diagnostic tool, using prisms and temperature measuring equipment to measure the wavelength distribution of stellar spectra. In addition, Herschel discovered infrared radiation. Other work included an improved determination of the rotation period of Mars, the discovery that the Martian polar caps vary seasonally, the discovery of Titania and Oberon (moons of Uranus) and Enceladus and Mimas (moons of Saturn).
Herschel was made a Knight of the Royal Guelphic Order in 1816. He was the first President of the Royal Astronomical Society when it was founded in 1820.
Johann Elert Bode (1747-1826) was born in Hamburg. His first publication was on the solar eclipse, August 5, 1766. This was followed by an elementary treatise on astronomy entitled Anleitung zur Kenntniss des gestirnten Himmels, the success of which led to his being summoned to Berlin in 1772 for the purpose of computing ephemerides on an improved plan. In 1774, Bode started the well-known Astronomisches Jahrbuch, a journal that ran to 51 yearly volumes.
Bode became Director of the Berlin Observatory in 1786, where he remained until 1825. There he published the Uranographia in 1801, a celestial atlas that aimed both at scientific accuracy in showing the positions of stars and other astronomical objects, as well as the artistic interpretation of the stellar constellation figures. The Uranographia marks the climax of an epoch of artistic representation of the constellations. Later atlases showed fewer and fewer elaborate figures until they were no longer printed on such tables.
Bode also published a small star atlas, intended for astronomical amateurs (Vorstellung der Gestirne). He is credited with the discovery of Bode's Galaxy (M81). Comet Bode (C/1779 A1) is named after him; its orbit was calculated by Erik Prosperin. From 1787 to 1825 Bode was director of the Astronomisches Rechen-Institut. In 1794, he was elected a foreign member of the Royal Swedish Academy of Sciences. In April 1789, he was elected a fellow of the Royal Society.
