6 août 1672 - Polar Ice Cap Observed
Description:
Dutch scientist Christiaan Huygens and his DIY-better-than-Galileo’s telescope brought clarity to many of the mysterious features of the solar system, including the rings of Saturn. In August 1672 Huygens observed and illustrated a bright spot on Mars, which was later discovered to be a polar ice cap. The question of Martian water would plague scientists centuries later.Ajouté au bande de temps:
