There is a partial eclipse across Europe tomorrow. 25.10.2022. Don’t look up at the sun unless you have proper eclipse glasses. It can burn your retinas and blind you because of ultra violet radiation. But one thing you can do is look at the ground, either in a puddle and yo may see a reflection, or if you stand under a tree that’s in leaf you may see images projected on the ground that look like crescent moons. These are images of the sun as the moon partly glides across it. The reason for the images? The leave are acting like a pinhole camera.
