Dara Ó Briain is one of Ireland's most successful comedians, and he's also forging an international reputation as a children's author.
His latest children's book, Is There Anybody Out There?, explores how life began, how Earth was created, whether aliens might exist elsewhere in our solar system and the search for other planets like our own.
He joined Matt on The Last Word for a chat about his love of stargazing and how he pursued it during lockdown, getting kids interested in science and whether he thinks there might be alien life out there.
