Artwork of refractor telescope that found Neptune
Refracting telescope. Artwork of the 23 centimetre (9-inch) Fraunhofer refractor telescope at Berlin Observatory, Germany, on 23 September 1846, the night that it was used to discover Neptune. German astronomer Johann Galle, aided by Louis D Arrest, looked in a portion of the sky where the French astronomer Leverrier calculated a planet would be. This calculation was based on perturba- tions in the orbit of Uranus. Galle and D Arrest compared the night sky to a new but unpublished star atlas, and within a few minutes found an unknown object just 1 degree from the predicted position. Observations the following night showed that it had moved, proving that it was a planet

EDITORS COMMENTS
This artwork showcases the historic moment when the 23 centimetre (9-inch) Fraunhofer refractor telescope at Berlin Observatory played a pivotal role in the discovery of Neptune. On that fateful night of 23 September 1846, German astronomer Johann Galle, assisted by Louis D Arrest, peered through this magnificent instrument into a specific region of the sky where French astronomer Leverrier had predicted a new planet would be located. With their eyes fixed on an unpublished star atlas, Galle and D Arrest meticulously scanned the heavens until they stumbled upon an enigmatic object just one degree away from its projected position. The subsequent night's observations confirmed that this celestial body had indeed moved, providing irrefutable evidence that it was none other than a previously unknown planet. The significance of this groundbreaking discovery cannot be overstated. Through meticulous calculations based on perturbations in Uranus' orbit, Leverrier's predictions were brought to life with the aid of Johann Galle's refracting telescope. This remarkable piece of astronomical equipment not only unveiled Neptune but also solidified our understanding of planetary movements within our solar system. As we gaze upon this awe-inspiring artwork, we are reminded not only of humanity's insatiable curiosity about the cosmos but also how scientific collaboration and technological advancements have forever altered our perception and knowledge of space.
