Question: Have you ever seen a sunspot ?

I actually have! We had a big telescope in the roof of the physics building at college, but it’s very dangerous to look at the sun directly through it, so instead we projected the image of the Sun on one of the walls. We did that a couple times a month and finally managed to catch one just before the summer break 🙂
