Space scientist Maggie Aderin-Pocock said she had got her first inspiration to look at the night sky from Sir Patrick.
She told BBC News:
He was broadcasting before we actually went into space and he saw a change in our understanding of the universe, and he took us all the way through that, right up until today.
What he did was something very straightforward, he would tell us what to look for and where to look for it and for budding astronomers everywhere that is what we need, that information.
But he would tell us more, he would go into depth, he would take us on a journey through space and we can't ask for better than that really.
