General public


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. Because Mercury is so small from our perspective on Earth, you'll need binoculars or a telescope with a certified Sun filter to see it. You might also be able to attend a viewing party at a local museum or astronomy club event.  

WARNING! Looking at the Sun directly or through a telescope without proper protection can lead to serious and permanent vision damage. Do not look directly at the Sun without a certified solar filter.
