How Does Celestial Navigation explained in 3 Minutes Work?

Imagine you're playing with blocks, and you use their shadows to know where they are, that's like how sailors find their way on big, open oceans using celestial navigation.

Sailors look at the sky, especially at the sun or stars, and use them like a giant clock. Just like you might know it’s time for dinner when the sun goes down, sailors can tell what time it is, or even where they are, by seeing how high the sun or stars are in the sky.

If you're outside on a sunny day and you see your shadow, you can guess which way is north. Sailors do something similar with special tools called sextants, which help them measure angles between the sun or stars and the horizon. These measurements tell them their position, like knowing where you are in a big playground just by looking at your shadow.

Think of the sky as a giant map, and the sun and stars as markers. By comparing these markers to a chart they carry, sailors can figure out exactly where they are, like knowing which block you're on just by looking up!
