Exoplanets

This is a really nice representation of discoveries of the exoplanets, which maps them on the sky and assigns each a note. It celebrates the fact that this June the tally passed 4000. Each note and color represents some fact about the exoplanet represented; Phil Plait explains them at "Bad Astronomy". (He also explains why such a large number are clustered in one area of the sky.)
