The sky will put on a stellar show on Nov. 11, 2019, as Mercury crosses in front of the Sun. Transits of Mercury only happen about 13 times per century, so it’s a rare event you won’t want to miss! With the *proper safety equipment , viewers nearly everywhere on Earth will be able to see a tiny dark spot moving slowly across the disk of the Sun.
