Transit of Mercury

Watch this astronomical event as Mercury passes in front of the Sun. Live images will be streamed into the Tellus Theater, and special shows will be shown in the Bentley Planetarium at 8 and 9 a.m. Since both orbital planes must align for this to take place, this event won’t happen again until 2032. Included with general admission: $15.95; ages 3-17, $11.95; ages 2 and younger, free.
