Who hasn’t heard of the Seven sisters – also known as the Pleiades? It’s the most beautiful star cluster, and the most famous. It’s obvious to the naked eye and stunning through binoculars, and these nights it’s unusually easy to find.
A major display of the northern lights is unforgettable, and if you've ever seen an exploding meteor, you've never forgotten it. But one natural celestial sight tops all of those, a total solar eclipse. Not a lunar eclipse and certainly not a partial solar eclipse. After the totality in 2017 in places like Wyoming and the Carolinas, millions finally got to see one.
