Open Day 2016

23 September 2016 - 4pm-10pm - Leibniz Institute for Astrophysics Potsdam







170 Years Discovery of Neptune

The Open Day is inspired by the discovery of the planet neptune that took place exactly 170 years ago. On 23 September 1846, the astronomer Johann Gottfried Galle at the Berlin Observatory - one of the two predecessor intitutions of AIP - observed neptune for the first time, confirming theoretical predictions by the astronomer and mathematician Urbain Le Verrier. By the way: the logo of AIP today shows just this stellar constellation from 1846 that led to the discovery of neptune (Read more).
