Green flash Jess explores

Have you ever been at the beach enjoying a lovely sunset and just as the sunset a green light flashed before your eyes? No - it wasn't Superman flying through the air, it was actually a natural phenomenon that this week we'll explore.

Also, a word of warning - please do not EVER stare into the sun, you can damage your eyes and I do not want to be responsible for that! You can witness the green flash safely and in this episode, I'll tell you when to look!
