Ready to really howl at the moon? According to NASA, the year’s first full moon will reach its peak on Monday, January 13. Here’s what to know. The first full moon of 2025 is upon us.

Mars will hide behind the wolf moon Monday night as a result of a phenomenon known as an occultation, a fancy word that describes when a celestial body passes in front of another, according to NASA. Mars is currently shining the brightest we'll see it all year, according to Space.com, but the full moon's light will still drown out the red planet.

The full moon is called the wolf moon because of the idea that during January’s long, cold and dark nights, wolves make sure everyone can hear them. Like many other moons, it also has other names. Some call it the “Ice Moon,” “Old Moon” or the moon after Yule.
