The Moon is thought to have formed when an object roughly the size of Mars hit the Earth. The impact was so violent that it threw large amounts of the Earth's mantle into orbit. This material evenually coalesced and formed the Moon.
Ansel Easton Adams was an American photographer and environmentalist. His black-and-white landscape photographs of the American West, especially Yosemite National Park, have been widely reproduced on calendars, posters, and in books.
This iconic landscape photography by Adams is one of the 115 images included in the Voyager Golden Records â phonograph records containing sounds and images showing life and culture on Earth â which were included aboard Voyager 1 and Voyager 2 in 1977.
