Grab your telescope.
Sure, we all know what eclipses are, but have you ever heard of a lunar occultation? This is what they call it when a star vanishes behind the moon and then reappears as the moon continues its cycle.
There are two types of occultations: grazing and total. A total occultation is when the entire star passes behind the moon. A grazing occultation is when the star looks like it's sliding along the edge of the moon. Tonight, one of the brightest stars in our sky, Aldebaran, will be part of a total occultation.
This spectacle can best be seen from the United States and Canada, according to Space.com. The star will begin to disappear around 10 p.m. PDT, and will reappear roughly 75 minutes later on the darker side of the moon. You can also follow the lunar occultation on this website, which shows the event's entire path.
