Stargazers’ delight: Lunar eclipse, comet, and ‘Snow Moon’ in one incredible night

Stargazers are in for a triple treat: Friday night will feature a type of lunar eclipse, the Full Snow Moon, and even a comet. 

You’ve likely heard of a “supermoon,” when the full moon appears brighter than usual because it’s closer to Earth. Friday night, something different will happen, in effect. The full moon will be darker.

That’s because the Earth’s natural satellite will experience something called a penumbral eclipse. A full lunar eclipse happens when the Earth is right in between the sun and the moon, casting its shadow onto the moon. In a penumbral eclipse, it’s just the edge of the Earth’s shadow (the penumbra) that ends up on the moon, meaning the moon should just appear to be a little darker on one side. (The full, dark part of the shadow is called the umbra.)


This phenomenon will be at its maximum at 7:43 tonight, EST, according to The best place will be the eastern side of the U.S. If you are outside and in a dark area at that time, look up to the east and check the moon for shading. Don’t worry, that’s not an alien spaceship casting a shadow on the moon. It’s just our own planet.

Because it’s February, the full moon is also called the Full Snow Moon, according to a tradition.
