On 27 of november , I saw how Jupiter eclipsed Io.
First, I located Jupiter with my telescope. Later, I saw where was Io, and I saw how Io saw it time less. Roemer, in the year 1676, discovered the velocity of the light thanks to the eclipses of Io.

Very good Pablo. But, how did Roemer know the speed of light?
