When we get two Full Moons in the same calendar month, as we will on the 1st and 31st this month, the second is called a Blue Moon. Discover why this happens and when you can see both moons this month, and more in May's Sky Watch.

Written by Petersphere resident, astronomical expert and amateur astronomer Geoff Burt, and voiced by Claire Vennis, every month Shine Radio presents a Sky Watch of our unique dark skies.

Let Shine Radio open up the wonder of Petersfield's night skies for magical star-gazing from your doorstep, in Sky Watch.
