Reach for the stars


Join us in the James S. McDonnell Planetarium for our live star shows each day. The Planetarium has taken precautions to ensure a safe star show with reduced capacities and enhanced cleaning. Learn more information on the Planetarium and star show schedules.

Spring Stars & Constellations

When you are not enjoying these live star shows with us, you can become an astronomer in your own backyard. Here are the stars you will see rise just after sunset in spring. Look east around 9pm to catch sight of these beautiful wonders.

1: “The Big Dipper” / Ursa Major

The Big Dipper is often the first star pattern people learn, but it is not an official constellation. Instead, this familiar asterism is part of the larger constellation named Ursa Major, the Great Bear. Ursa Major is rising from its winter slumber and will climb higher in the sky during the spring and summer.

2: Arcturus

Follow the ‘arc’ created by the three stars in the handle of the Big Dipper as they point to the bright star of spring, Arcturus. This red giant in the constellation of Boötes the Herdsman is the 4th brightest star in the night sky. The pattern of Boötes often is described as looking like a kite or ice cream cone.

3: Spica

Below Arcturus is another bright star named Spica. The name for this blue-white star comes from Latin where it means “wheat.” To early farmers, Spica’s appearance in the east after sunset was used to mark the start of spring, and its disappearance in the west nearly six months later began the annual harvest. Spica is carried across the sky by the Zodiac constellation Virgo the Maiden.

4: Leo the Lion

March is often described as coming “in like a lion and out like a lamb.” In the stars, our springtime lion is the famous Leo climbing high in the sky during the spring. For those with a telescope, this pattern contains the famous Leo Triplet—a group of three interacting spiral galaxies roughly 35 million light years from Earth. The triplet is best viewed during the spring from dark skies.

5: Coma Berenices

This seemingly empty patch of sky is our James S. McDonnell Planetarium Manager Will’s favorite spring constellation! Don’t see anything? Blame that on the city lights of St. Louis. This small constellation contains few stars bright enough to be seen in and around the city, but its hidden beauty is revealed from a dark location. Coma Berenices, named for the Egyptian queen Berenice II, contains countless faint stars, rich galaxy clusters and more hidden treasures.
