In this series we are exploring the weird and wonderful world of astronomy jargon! You’ll see from one side to the other of today’s topic: the celestial sphere!
We live on the surface of the Earth, which is a globe. To help us orient ourselves and navigate around, we draw pretend lines on the globe. The lines of latitude run parallel to each other from east to west, and the lines of longitude run from north to south. You can name any position on the Earth in reference to these lines. We also have a few special places, like the equator that runs around the middle of the globe, and the two poles.
