| This famous "Blue Marble" shot represents the first photograph in which Earth is in full view. The picture was taken on December 7, 1972, as the Apollo 17 crew left Earth’s orbit for the moon. With the sun at their backs, the crew had a perfectly lit view of the blue planet. |

| This photo reveals the first view of Earth from the moon, taken by Lunar Orbiter 1 on August 23, 1966. Shot from a distance of about 236,000 miles (380,000 kilometers), this image shows half of Earth, from Istanbul to Cape Town and areas east, shrouded in night. |

| When Apollo 8 was deployed in 1968, its sole photographic mission was to capture high-resolution images of the moon’s surface, but when the orbiting spacecraft emerged from a photo session on the far side of the moon, the crew snapped this, the most famous shot of the mission. Dubbed "Earthrise," this view of the Earth rising from the horizon of the moon helped humans realize the fragility of their home. |

| The first Martian's-eye-view of Earth and its moon was captured on May 8, 2003, by a camera aboard NASA’s Mars Global Surveyor craft. Shot from Mars at a distance of 86 million miles (139 million kilometers) from Earth, the image reveals an illuminated slice of Earth’s Western Hemisphere—as well as a celestial perspective of the world in which we live. |

| This 2004 photograph made by the European Southern Observatory shows the first known photo of an exoplanet, or a planet beyond our solar system. The red orb at bottom left is a young planet, similar in composition to Jupiter, orbiting a brown dwarf, a dim, failed star that is probably 42 times less massive than the sun. An infrared camera, which reacts to heat rather than light, shot these photos from a distance of some 230 light-years. |
