For the first time in a decade, you can watch the planet Mercury cross paths with the sun.  The dot will be visible to the majority of Earth on Monday, May 9, and The Nature Institute is organizing a viewing party at Alton's Heartland Prairie, on the north side of Illinois Route 140 across from Gordon Moore Park.

TNI's Naturalist to the Stars, Eddie Agha, tells The Big Z he will be bringing some special equipment to the Prairie that morning to allow us to watch what is called The Mercury Transit.

The last transition of Mercury happened in 2006, and the next one will not happen until 2019.  You are asked to call ahead to reserve a spot at the party.  Ro do so, call 466-9930.
