A free show will be offered tonight at the planetarium at Indiana University of Pennsylvania.
The show, "The December 20-21 Total Lunar Eclipse," is open to the public and will run about 40 minutes.
Dr. Kenneth Coles will also present the ever-popular look at the current stars and planets in the sky.
Coles said in the early hours of Dec. 21, the moon will pass through the earth's shadow.
With clear weather or a break in the clouds, it is worth a look.
The moon will enter the earth's shadow at 1:33 a.m., and the darkest phase will be from 2:41 to 3:53 a.m. Wednesday.
The eclipsed moon typically turns a deep red color, but it varies from eclipse to eclipse.

Seating for the show is on a first-come, first-seated basis. To bring a large group of 10 or more people, call Coles at (724) 357-5626, (724) 357-2379, or e-mail email@example.com.
The planetarium is in the east side of Weyandt Hall. Doors open at 6:45 p.m.
