Prepare to howl with delight at the first full moon of January 2025, the wolf moon, one of several wonders in the night sky this month.

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.

The full moon completely covered Mars on Monday, Jan. 13, in a rare lunar event. Take a look at footage from Cincinnati astronomer Dean Regas.

In the Bay Area, the event will begin around 6 p.m., shortly after both Mars and the moon appear above the horizon.
