Earthlight is a science fiction novel by British writer Arthur C. Clarke, published in 1955. It is an expansion to novel length of a short story that he had published four years earlier.
Earthlight is a scrolling shooter video game published for the ZX Spectrum in 1988 by Firebird Software. It was written by Pete Cooke.
The player takes the role of an alien explorer from the star-system of Arcturus, called Slaatn, who has been drawn off-course by a beam of energy from Earth and has had to make a landing on the moon. Slaatn must neutralise the box-like transmitters and thus eliminate the force field.
Earthlight is a shooter featuring parallax scrolling and shadow effects, a novelty for the Spectrum.
"Earthlight" is a science fiction short story by Arthur C. Clarke first published in the August 1951 issue of Thrilling Wonder Stories. It was later expanded into the novel Earthlight in 1955.
Earthlight, also known as earthshine, is the partial illumination of the dark portion of the moon's surface by light reflected from the Earth and from the Earth's airglow. It is also known as Earthshine (see Planetshine), the Moon's ashen glow, or the old Moon in the new Moon's arms.
This phenomenon is best observed from just after new moon, when the moon is a thin crescent. On these nights it is easy to see the entire disk of the moon. The word is rare but is recognised by the Oxford English Dictionary.
It would also be a suitable term for an observer on the moon seeing the Earth during the lunar night, or from an astronaut of the window inside a spacecraft. Arthur C. Clarke uses it in this sense in his novel Earthlight.

Earthlight is a feature on Earth's Moon, a crater in the Hadley–Apennine region. Astronauts David Scott and James Irwin drove past it on their rover in 1971, on the Apollo 15 mission, during EVA 2.
Earthlight is located about 1.5 km east of Hadley Rille, less than 1 km north of the larger Dune crater, and about 2 km south of the Apollo 15 landing site itself, at Last crater.
The crater is subdued and not obvious on the surface, and the astronauts did not stop to observe it. During the drive towards Mons Hadley Delta, Jim Irwin said, "I can just barely see the western slope of Earthlight. But the southern slope of it, I can also see, has several blocks on it." The crater was named by the astronauts after the novel by Arthur C. Clarke (which takes place in and around Mare Imbrium on the moon), and the name was formally adopted by the IAU in 1973.
