If you missed the Eta Aquarids meteor shower, which peaked early Tuesday, the sky has another show in store this week. The last supermoon of 2020, dubbed the "flower moon," will be visible from Tuesday evening into Friday morning but will appear largest (reaching the closest point to Earth in its elliptical orbit) early Thursday, around 6:45am ET, according to NASA. This follows three other supermoons in February, March, and April. April's "pink" moon was the biggest and brightest of the four, while May's moon coincides with Buddha's birthday, the holiday formally known as Vesak, per CBS News. (More supermoon stories.)
