Watch Mercury cross (transit) in front of the Sun.

Fiske Planetarium and Sommers-Bausch Observatory will host live events. Stop by for a few minutes or stay for the entire morning.  

Mercury will appear as a tiny dot moving across the brilliant Sun. Why is this a big deal?  This astronomical rarity will only occur 14 times this century. The next transit observable in North America won’t happen until 2049. So, you don’t want to miss this! The only other planet we can see cross in front of the Sun is Venus. The last transit of Venus occurred in 2012 and the next one won’t happen until 2117.

The only safe way to view this astronomical event is through a special solar telescope or projected via a Heliostat or Sunspotter. REMEMBER! Looking at the Sun directly or through a telescope without proper protection can lead to serious and permanent vision damage.

This event is FREE! Stop by or watch the livestream below. In the event of inclement or cloudy weather, please join the NASA Solar Dynamics Observatory livestream from space.
