On September 23, 1846, Astronomer Johann Galle pinpointed the planet Neptune through a telescope at the Berlin Observatory in 1846. To celebrate this event, the National Postal Museum has created this mini-exhibit highlighting different postage stamps with connections to the Planet Neptune and the timeline of its discovery.
Neptune’s place in the history books is nearly as stormy as its weather, which is more violent than anywhere else in our solar system. Since Pluto’s demotion from planet status, Neptune now claims the distinction of being the farthest planet from the sun…but that certainly doesn’t mean it’s off our radar. Though it can only be seen through a telescope, its position in space was determined without the use of this optical tool.
