Get Ready for Mercury to Transit the Sun!
On Monday May 9th, Mercury will make its rare transit across the face of the Sun. This celestial event is a must-see and if you miss it, you’re out-of-luck until November of 2019.
What does it mean for Mercury to “transit” the Sun? This term is used when a planet is directly between the Earth and another object (in this case the Sun). On May 9th when Mercury makes its way between us and the Sun, we will experience a partial eclipse.
According to NASA, the transit will begin on Monday morning around 7:15 a.m. EDT and will last over seven hours. Luckily, everyone in the US will be able to observe the event and in fact, with the exception of Australia, New Zealand, and several areas of eastern Asia, nearly everyone on earth will be able to view this event.
How can I watch this event?
Technically, you can view this transit with the naked eye; however, it is not recommended to stare directly at the Sun. The best and safest way to view Mercury in transit is with a telescope fitted with a safe solar filter.
