Treat in the Sky Tonight; Free Party too!

December 20, 2010

There is going to be a full lunar eclipse late tonight on the winter solstice, the longest day of the year.

A total lunar eclipse occurs when the full moon passes through the shadow of the Earth, which is blocking the sun’s light.

Since the eclipse is occurring on the winter solstice, the moon will be high in the sky and great for viewing — weather permitting, of course.

If skies are clear, North America will have a great seat for the show. The total eclipse begins at 1:41 a.m. in Chicago and will last a little over an hour.

The Adler Planetarium will be a great place to view the total lunar eclipse, weather permitting.

The Adler Planetarium could be a great place to view the total lunar eclipse, though snow could mess up the party.

The Adler Planetarium is hosting a free Total Lunar Eclipse Party. You can bring your own telescope or use ones provided by the Adler.

The next total lunar eclipse visible from the Chicago area will be on April 15, 2014. The next total lunar eclipse on the winter solstice: December 21, 2094.

Try to catch this one, since it’s hard to plan 84 years in advance.
