And from the perspective of the moon, Earth would also always appear to be in a fixed location. The Earth would also look much bigger than the moon does to us. But because the moon has no atmosphere, you would still be able to look at the stars during the day. If the part of the moon you're on is experiencing day, your observations of the cosmos might be affected by the sun glaring off your helmet or moon rocks, Shupla noted. Your view of Earth, however, might not be crystal clear. "You would see potentially lights on the Earth in cities." "It wouldn't just look dark," Christine Shupla, the education and public engagement manager at NASA's Lunar and Planetary Institute, told Live Science. To a person standing on the moon, this full moon's reflected light (and maybe some artificial light) might make the new Earth faintly visible. At that point, Earthlings would be basking in the light of the full moon. Over the following two weeks, moon dwellers would see a shrinking crescent of Earth until the moon was directly facing the darkened nighttime side of the planet. While Earthlings stare at a darkened new moon (when the side of the moon facing Earth is not lit up by the sun), a lunar observer would be looking at a "full Earth," the half of the planet totally illuminated by the sun. The month-long cycle of waxing and waning that we see is just the long lunar day turning into night as the moon orbits Earth. Lunar phases occur because one-half of the moon is always lit up by the sun. And Earth would indeed appear to go through phases over the course of about a month, directly opposite to the lunar phases people on Earth would be witnessing, said Phil Nicholson, professor and deputy director of the Cornell Center for Astrophysics and Planetary Science in Ithaca, New York. If you were based on the near side, you'd see Earth all the time. If you were camped out on the far side of the moon, you'd never have a view of Earth.
