Summary
| Description |
English: Excerpt from the Hora XXI sky chart of the Berlin Science Academy completed by Carl Bremiker. The work on the chart started in 1826, but was completed only in 1844 and printed in 1845. It laid untouched until 23 September 1846 when Johann Gottfried Galle and Heinrich Louis d’Arrest used it to discover Neptune, based on the theoretical prediction by Jean Joseph Urbain Le Verrier. The predicted location (square) and the observed location (circle) were noted in pencil, allegedly by Galle, but at some time after the discovery.
Text pencil markings left: top: "Neptun beobachtet" ("Neptune observed"), bottom: "Neptun berechnet" ("Neptune calculated") Text printing bottom: "Theil des Himmels zwischen XXIh und XXIIh der geraden Aufsteigung, und 15° südlicher bis 15° nördlicher Abweichung, für 1800 auf Veranlassung der Königlichen Akademie der Wissenschaften in Berlin, entworfen von Herrn Doctor C. Bremiker in Berlin. gedr. v. Prêtre." Text translation: "Part of the sky between 21h and 22h of right ascension, and 15° south to 15° north declination, for 1800 on the initiation of the Royal Academy of Sciences in Berlin, drafted by Doctor C. Bremiker in Berlin. printed by Prêtre." The complete map can be found here: https://www.aip.de/en/news/175th-anniversary-of-the-discovery-of-neptune/ |
