Mark your calendars, folks. Venus will pass between the Earth and the Sun — what is known as a transit — on the evening of June 5th (as seen from North America). On this date (and with the proper eyewear) you can watch Venus move across the face of the Sun. This is a rare event — the next Venus transit will occur over one hundred years from now.

Tons of details — including how to safely observe the transit — are here.
