Rømer Project: Are you ready to measure the speed of light?

If you've got a telescope and you like astronomy, we urge you to take part in our project.

Have you ever thought about light? What's the most striking thing about it? It speed, of course...exceeded only in our imagination. Ready to meet the challenge of measuring it? In this project we aim to relate a simple astronomical observation with a universal constant, c (the speed of light), and tell you about one of the greatest contributions to astrophysics in the history of science.
