Moon, Jupiter, and Beehive
This single telephoto image captured several celestial objects, each at radically different distances from Earth:
- In the upper left is Earth's moon. Above the brightly-lit crescent portion, the dark side of the moon is illuminated by "Earthshine" -- sunlight reflected off the far side of the Earth. This is also known by the poetic name "the new moon in the old moon's arms." The moon is 228 thousand miles from Earth.
- In the lower right is the bright planet Jupiter. If you look very close to Jupiter, you can see two of the planet's moons: Ganymede (above) and Callisto (below). Jupiter is 56 million miles from Earth.
- Between the moon and Jupiter (but closer to Jupiter) can be faintly seen a sprinkling of stars known as the "Beehive." Also known as the Praesepe, M44, and NGC 2632, this star cluster is 3 quadrillion (3,000,000,000,000,000) miles from Earth!
