Night Sky Photos

There is a great place were astrophotografers keep their best photos. Have a look at AstroBin were amazing photos are stored and shared. Browse through the pictures or go directly to the Image of the day. A somewhat related service is Astrometry where you can submit your picture to find out what part of the sky it shows.

Another place taking a lot of pictures of the sky is the Sloan Digital Sky Survey. SDSS is mapping the sky and their pictures are used by Google and Microsoft among others. Go to the SkyServer or the gallery.

August 23 – Black Ribbon Day

This day 76 years ago Nazi Germany and the Soviet Union signed the Molotov-Ribbentrop Pact. A second World War later millions of people were killed. After the war the Soviet Union continued the systematic killing.

August 23 is now the Black Ribbon Day or European Day of Remembrance for Victims of Stalinism and Nazism.

We know more about how many were murdered by the Nazi’s but not exactly how many are (still being) murdered by communists. The Black Book of Communism tries to answer that. If you dare you can read it here.
