Today (November 11, 2019) is the last time you will be able to watch Mercury transit across the face of the sun until 2032.  From sunrise EST until about 1:04 PM EST, people who are equipped with special super shades and giant weird specialty telescopes will be able to watch the tiny black dot of Mercury move across the face of the sun.  Mercury is slightly larger than Earth’s moon (although it much more dense) but it is also much farther away from Earth.  As the innermost planet moves between the sun and Earth, viewers here at home can watch…provided they have lots of weird specialty equipment (whatever you do, don’t stare directly at the sun or point any unfiltered lenses at it).  If you are like me, you certainly don’t have these sorts of optical tools lying around. But never fear: NASA is there for you, and you can watch the show with their fancy equipment via their site (or you can check out pictures after the event, in case you didn’t look at this post until it was too late). Enjoy this transit!  We can talk about the larger implications and about future plans for Mercury during the next transit in 2032…
