What he done to be famous
Christiaan Huygens discovered the Orion Nebula and the rings of Saturn . Christiaan Huygens also focused on light and its mechanics in the 17th century. One day Huygens discovered a large moon orbiting Saturn so he called it Titan. Huygens work also helped other future scientists to show that there could be extra terrestrial life in our solar system. Huygens also had three theories focused on light but his third theory was the one that was proved most important. Huygens proposed that light travelled in waves and from this calculated the laws of reflection and refraction.
