A celestial event is occurring Thursday night. Earth's shadow will cover a large portion of the moon. This phenomenon is expected to reach its peak shortly after midnight. At that time, the moon may take on a reddish hue.

The moon's appearance will be altered as it moves into the darkest part of Earth's shadow. A small part of the moon will remain illuminated.

Further details about this event are available, including what to expect and how to view it.
