Happy St Patrick's Day - from space!

St Patrick's Day celebrations are in full swing right around the globe - and beyond.

Canadian astronaut Chris Hadfield is celebrating our national holiday as the International Space Station passes over Ireland.

He first tweeted cúpla focal to wish us a good morning.

Maidin mhaith from the International Space Station! Happy Saint Patrick's Day to the Irish all around the globe. Good morning!

He's also dressed for the occasion, sporting a natty green bow-tie.

He even has treated us all to his favourite Irish song, sung from outer space.

He also gave us a peek of what Tralee and Derrylook like from above today.
