Colors of the Moon
Explanation: What color is the Moon? It depends on the night. Outside of the Earth's atmosphere, the
dark Moon, which shines by reflected sunlight, appears a
magnificently brown-tinged gray. Viewed from inside the
Earth's atmosphere, though, the moon can appear quite different. The featured image highlights a collection of apparent colors of the full moon documented by one astrophotographer over 10 years from
different locations across
Italy. A
red or yellow colored moon usually indicates a moon seen near the horizon. There, some of the
blue light has been scattered away by a long path through the
Earth's atmosphere, sometimes laden with fine dust. A
blue-colored moon is more rare and can indicate a moon seen through an atmosphere carrying larger dust particles. What created the purple moon is
unclear -- it may be a combination of several effects. The last image captures the
total lunar eclipse of 2018 July -- where the moon,
in Earth's shadow, appeared a
faint red -- due to light
refracted through
air around the
Earth. The next full moon will occur at the end of this month (
moon-th) and is known in some cultures as the
Beaver Moon.
