Johannes Kepler’s (December 27, 1571 – November 15, 1630) primary contribution to the astronomy field was his laws of planetary motion. Not only are these concepts important to modern day astrophysics (such as when sending satellites to study distant planets), but also lay the foundation for Newton’s work on universal gravitation. One major astronomical event that happened […] Continue reading
