The first full moon, a wolf moon, will rise tonight and some parts of the world will be treated with a penumbral eclipse.
A penumbral eclipse is when the moon passes through the Earth’s outer shadow, leaving a faint smudging on the moon’s glowing surface. Unfortunately, the eclipse won’t be visible in the continental United States. It is the first penumbral eclipse since 2017.
The reason the first full moon in January is called a wolf moon dates back to Native Americans. They noted that wolves had grown hungry throughout the long winter. According to the Farmer’s Almanac, the packs of wolves would howl outside Indian villages.
