What are astrolabes?

An astrolabe is like a fancy, ancient clock that helps people tell time and find out where stars are in the sky.

Imagine you have a spinning top, but instead of just spinning around, it shows you what the sky looks like at different times of day or year. That’s kind of how an astrolabe works, except it's flat and has little pieces that move to show where the sun, moon, and stars are.

Think of your favorite toy watch, when you wind it up, the hands move around the numbers. An astrolabe is like a watch for the sky. You can use it to tell what time it is by looking at the position of the sun or stars. People used it in ancient times to plan their travels, know when to plant crops, and even do math problems!

If you had an astrolabe on a sunny day, you could point it toward the sun and see what time it is, just like how you might use your phone or a clock. But instead of numbers and hands, there are little lines and circles that move to match the sky.

It’s like having a magic map of the sky that you can turn and twist!
