On Wednesday this week, 26 May, we're heading outside to spot a cosmic coincidence in the evening sky - a lunar eclipse. Just after sunset, the moon will start to pass into the Earth's shadow, and by 7.18pm it'll be completely covered. Take us with you for a guided commentary on how and why it's happening!

Make sure you've got this episode downloaded and ready to go, and remember to take insect repellent and a jumper if it's cold. We'll see you outside!
