For this week's theme of astronomy/science/scientists, the first stamp is a GB one and was issued in September 1990, it depicts Armagh Observatory, Jodrell Bank Radio Telescope and La Palma Telescope. This stamp was the lowest value in a set of 4, but I only have this one.
The next stamp was issued by Germany in 1993 and commemorates Paracelsus, (wiki link) who was a physician, botanist, alchemist, astrologer and occultist. So I'm probably stretching the theme a little here, but I liked that it shows the planetary symbols used in astrology.
And finally this mini sheet was issued by Egypt in March 2006 and shows the total solar eclipse.
