NASA Hot Topic Our Solar System: Galileo’s observations of the Moon, Jupiter, Venus, and the Sun
revolutionized our understanding of the solar system and our place in it. NASA’s explorations of
our solar system - and observations of planets around other stars - continue the revolution,
sparking the imagination of learners of all ages.

Go Observe with NASA The Moon: The Moon is the closest astronomical object to the Earth. Galileo was the first to
observe craters and mountains on the Moon. NASA spacecraft scheduled to launch in 2009 will
map the Moon in amazing detail and search for evidence of ancient ice to help prepare for
future human exploration.
