The Victory Column near the center of the Tiergarten (info).
The Sony Center at Potsdamer Platz. This is the brightest area (in terms of skyglow) in the entire city. (map)
The Church at Sudstern. The floodlights used to light the church are not well designed. They blind viewers of the church from above, and hinder people on the ground from seeing the heavens. The Brandenburg Gate is beautifully lit without floodlighting (see images further below). (map)
Tegel airport, which is scheduled to be eventually shut down. (map)
A wide angle view of Tegel airport. The surrounding area is quite dark, but suffers exceptionally from the skyglow produced by this single bright source of white light.
Schönefeld Airport, which will soon be replaced by Berlin Brandenburg International Airport. Note the different in lamp color and brightness compared to Tegel airport above. (map)
The Brandenburg Gate from the ground. Architectural lighting can make famous landmarks even more impressive at night than during the day, but it's not clear to me that there is a strong case for such lighting to be on for the entire night. (info)
A view of the Brandenburg Gate and the German Reichstag, looking East (from above the Tiergarten.
A view of the Brandenburger Gate and the Reichstag looking West (from above Unter den Linden).
This photo was taken through the nadir viewing port in the aircraft as we passed almost directly over the Reichstag and Brandenburger Tor. A two minute video below shows the view through the port over a large section of Mitte.
View of Berlin Hauptbahnhof (main train station) at night. Note the reflections from the Spree river. (map)
Another view of Berlin Hauptbahnhof.
A mosaic image of central Berlin at night made up of thousands of individual aerial photographs.
For comparison to the above photo, this image, based on the famous DMSP/OLS Earth at Night dataset, covers roughly the same area.
A high quality image of Berlin at night taken by astronauts aboard the International Space Station (image taken in 2013 and courtesy of the Image Science & Analysis Laboratory, NASA Johnson Space Center). An even higher resolution image, albeit one with some clouds, is available here. A wideangle view is also available.
A blown up view of the region near Tegel airport from our mosaic image of Berlin at night.
This image shows two of Berlin's most famous churches (Berliner Dom and Marienkirche), as well as the Marx-Engels Forum and the spire of the Rotes Rathaus. This view of one of the most historic areas of the city is dominated by copious blue light from a modern building. Besides spoiling this view, blue light produces far more skyglow than lights which emit longer wavelengths.
Berlin's TV tower (Fernsehturm) and Alexanderplatz. (map)
A wider angle view of Fernsehturm and Alexanderplatz.
These false color images show how light pollution obscures the lunar "celestial compass". The signal at right is used by some nocturnal animals for navigation, but in the city it is no longer visible on most nights. Click on the image for a more detailed explanation.
This photo was taken from the top of our measurement tower at FU Berlin, where we perform our skyglow experiments. It shows how clouds amplify the impact of light pollution. In natural areas clouds appear as dark objects in the night sky, while in urban areas clouds brightly reflect light back to Earth. The bright orange tower at left is "Funkturm Berlin".
This photo was taken by Ray Stinson, and shows how clouds darken prinstine skies. The two photos are displayed side by side here.
Berlin's Mitte district, with Tiergarten at bottom left, and Alexanderplatz at top center.
When flying over the city at night, stadiums and soccer fields jump out at you as very bright sources of light.
This image shows how light pollution is strongly scattered by aerosols below the planetary boundary layer, but not so strongly scattered by the clean air above.
Berlin's Tiergarten is in the center of this photo, which is oriented so that North is upwards. Tegel airport can be seen at top left, and Alexanderplatz at center right. This map shows a roughly analagous area.
The Cessna that we use for our flights over the city at night. There is a hole in the bottom of the aircraft over which a motion stabilizing platform is based. Our scientific cameras are mounted on the platform to compensate for the motion of the aircraft. Most of these images on this page were taken with my personal camera pointing out of the window.
Taking high resolution photographs at night from an aircraft requires an exceptionally light sensitive camera. Much finer details can be resolved during the day, as this test photo from one of our early daytime flights shows.




Videos





Alejandro Sanchez de Miguel put together this video showing views of Berlin at night from our aircraft. If you like it, take a look at this older video showing a flight segment from Alexanderplatz to Ernst-Reuter-Platz.






This video shows what it's like inside of the aircraft when we fly at night. Click on full screen or watch at youtube for better resolution.






This is a ten minute talk I gave about light at night for a "Science Slam" in Leipzig. The first minute or so is in German, but the rest of the talk is in English.






In this three minute talk I discuss why citizen science is an appropriate tool for doing skyglow measurements.






In this four minute video I explain my sciencestarter project (German).






This is a three minute talk I gave about how the skyglow from urban areas blocks the view of the celestial compass.






This is a three minute talk I gave on the importance of thinking about the production of and exposure to artificial light at night. (For the record I meant to say "possibly increased risk of cancer." This is an open question that is under vigorous debate.)






This is a 9 minute Science Slam about demographic changes in our experiences of light and darkness.
