This week we turn our gaze skywards to tackle three questions about what’s going on above us. Three year old Zac from the UK wants to know what clouds feel like – if they’re supposedly like steam, then how are they cold?

Presenter Graihagh Jackson meets a meteorologist who can not only tell us but show us the answer, as we attempt to make a tiny cloud at ground level in the studio. Listener Agnese is looking beyond the cloud base and up to our nearest neighbour. She’d like to know why it is that we can see the Moon during the day. And Graihagh heads out to one of the longest-running and largest steerable telescopes in the world: The 76-metre Lovell Telescope at Jodrell Bank Observatory in the UK. Here, she finds out the answer to Sandeep from India’s extra-terrestrial question: Could aliens find us?
