A GOBLIN MOON TONIGHT
For the first time in 46 years, Halloween goblins can trick or treat by the light of a full moon. They won't get another chance until 2020.
Tonight's full moon will look like a jack-o'-latern as it rises, appearing orange at the horizon because it's seen through denser layers of the atmosphere.
Pleiades, or the Seven Sisters, a constellation associated with calamity, also will be at the top of tonight's sky.
The Aztecs and Mayans believed that the open cluster of stars, which looks like a cluster of grapes, would be overhead at midnight when the world ends.
The Seven Sisters and the full moon will be directly overhead at midnight.
