On December 24, 1968, astronaut Bill Anders of Apollo 8 was gazing out at the Moon just as they were about to re-establish communications on the Earth-side of the Moon and he saw a magnificent scene: The Earthrise. They scrambled for a suitable camera with suitable film and Anders finally caught the scene on 70mm color film. Then 47 years later in 2015, a little robot named the Lunar Reconnaissance Orbiter, took a series of b/w and color photos on October 12, which were recombined into this beautiful, stunning image.

These links (far from a complete list) will help get you started. It's one way to contribute directly to live ongoing science. https://boinc.berkeley.edu/ https://setiathome.berkeley.edu/ http://lhcathome.web.cern.ch/ https://einsteinathome.org/ https://foldingathome.org/ Make sure that your PC has proper cooling and ventilation. In particular cleaning out dust from the heat sinks with canned air is a good idea. Also beware that some discount GPU cards may not be able to tolerate the additional load in which case it's better to only enable CPU processing. And if you have overclocked your GPU and/or CPU, it might be good to lower the settings a bit to make sure it can tolerate 24/7 high load. The project sends each "work unit" out to three clients. You can guess how that works out for accuracy in the recombined result.
