The crescent Earth as viewed by the Rosetta spacecraft in November 2009, on its way to the outer solar system, and an eventual encounter with Comet P67 (in November 2014). (ESA (MPS for OSIRIS Team), MPS/UPD/LAM/IAA/RSSD/INTA/UPM/DASP/IDA, apod091123)
The Earth rising above the lunar horizon as photographed from Apollo 8 in lunar orbit on December 24, 1968. Every living creature known to exist, every hope and dream of any man or woman who ever lived is centered in this small blue ball. In the limitless immensity of space, do other such orbs revolve around other stars? Do other creatures look at the heavens and wonder, "Are we alone?" Everyone may have an opinion about these questions, but no one knows the answers. (Apollo 8, NASA, apod051224)
The Earth and Moon from a distance of nearly four million miles, in an image taken by the Galileo spacecraft on December 16, 1992, eight days after a very near flyby of the Earth (less than 200 miles from the surface at perigee) which increased its speed and sent it on its way to Jupiter. The contrast in brightness between the two objects may make the Moon appear to be "behind" the Earth, but it is actually in the foreground, a quarter million miles closer to the spacecraft than the Earth. North is on top in this image, so the Moon, moving eastward around the Earth, is moving from left to right. Although color and brightness are enhanced for both objects to improve visibility, the striking contrast between the brightly-colored life-filled Earth and the dark lifeless surface of the Moon is very real.
