Seasons Greetings


Celebrate the Seasons!

The winter solstice is when the sun is lowest in our sky, but there are reasons to look up all year long. Discover the nature of our seasons and why the winter solstice has long been a time of celebration in this live star show.

As we gaze up to the winter sky, we’ll also look back at how cultures are united in celebration during the winter season and how these celestial sights still influence our holidays today.

The Grand Conjunction

Jupiter and Saturn will meet in the night sky over St. Louis on December 21, 2020. This event, called the Grand Conjunction, only occurs every 20 years!

A “conjunction” is when two objects share the same right ascension in the sky. The two planets will appear exceptionally close together this year.
