Happy (belated) St Patrick’s Day! Here in Galway in the Republic of Ireland we celebrated St Patrick’s Day with a huge parade. In Dublin, the capital of Ireland, some half a million turned out for their parade. But no matter where you live in the world, you probably heard something about St Patrick’s Day because it is celebrated in more countries than any other national festival! In fact this year, for the first time in history, it was celebrated on Antarctica! The Irish among that small community of 135 scientists organised a parade that totalled eight floats. One St Patrick’s Day celebration was literally out of this world, when in 2011 two Irish-American astronauts performed a song by The Chieftains on the International Space Station!
