An astrolabe is an ancient instrument used by astronomers and navigators to measure the altitude of celestial bodies and determine latitude for navigation.
Think of an astrolabe like a GPS system in your car. Just as a GPS uses satellites to pinpoint your location, sailors would use an astrolabe to locate their position based on the stars.
Celestial Navigation: This is the practice of using observations of celestial bodies (like stars, planets, the sun) to navigate. It's like using landmarks in a city to find your way around.
Latitude: Latitude refers to the lines that run horizontally across our globe. Imagine them as "rungs" on a ladder ("ladder-tude") stretching from east to west.
Longitude: Longitude refers to vertical lines running from north pole to south pole on our globe. They're like slices in a round cake, helping us divide up the world into manageable sections for navigation.
