This month I visited Birr Castle in Co Offaly to visit the Leviathan of Parsonstown which was once the largest telescope in the world. It managed to stay that way for 70 years until the Hooker Telescope was built in California in 1917.
I was once again joined by my sister Megan and she helped me share some great facts about the 7th planet in the Solar System. Please watch below and make sure you watch to the end for the bloopers!
