Tomorrow the planet Mercury moves along the face of the sun in what is known as a transit and we can see it. The Mercury transits occur about every 13 years.
First – DO NOT EVER look at the sun without ADEQUATE eye protection!!!!!
If it is cloudy where you are, no worries, check back here tomorrow for links for on-line sources. Today a couple of video’s.
The first from Physics World entitled, Guide to the transit of Mercury 2016:
and the second from Science@NASA, an updated version of the video I put up a week ago titled, ScienceCasts: The 2016 Transit of Mercury (updated):
Also here’s a pdf with great information from the US Naval Observatory.
