How did most of the moon's craters form
WebIt’s not a riddle, it’s the Moon! For centuries, astronomers debated whether water exists on Earth’s closest neighbor. In 2024, data from NASA’s SOFIA mission confirmed water exists in the sunlit area of the lunar surface as molecules of H 2 O embedded within, or perhaps sticking to the surface of, grains of lunar dust. Weba rather myopic Earth-dominated view: most craters we see today on Earth have volcanic origins, so they assumed the same for the Moon. Many of the large lunar craters would have had to form by the impact of projectiles many kilometers in diameter, and the presence of such large Earth-crossing asteroids was not known until about forty years ago. 16.
