The picture is of the plaques that are on the Pioneer 10 and 11 probes which were launched in the early '70s and are the 2nd and 4th most distant man-made objects, being beaten only by the younger Voyager craft. P10 is now more than 3 times as far away as Pluto, as is V1 in the opposite direction. Unbelievably V1 and V2 are still sending back data.

I first started BOINCing soon after it started as an upgrade to SETI classic, when I found that I couldn't run it and the early CPDN models together, but could when they both moved to Boinc.
My favourite project is the building of the new particle accelerator at CERN. I can only comprehend a small fraction of the science that they will be able to perform there when it is completed but I am happy that I have contributed in some small way towards the unravelling of the complexity of the universe. With WUs being limited there as they design, build, calibrate each section, I need other projects to keep my machine busy and this one is doing similarly pure science.
