Everything you need to know about the full “Wolf Moon,” including exactly when, where and how to see it at its best from where you are, including an occultation of Mars.

On January 13, stargazers will be treated to a spectacular celestial event as the Wolf Moon—the first full moon of the year—passes directly in front of Mars. This will create a rare occultation that will capture the attention of astronomy enthusiasts across various regions.

The Wolf Moon — the first full moon of the year and of winter in the Northern Hemisphere — will be best seen on Jan. 14, shortly after it has occulted Mars.

On Monday evening, the moon and Mars will appear very close together before the moon appears to pass in front of the Red Planet. The occultation takes place over a couple of hours, according to NASA.
