Once a month, on the first Saturday, a special sky show for little ones up to two years will be shown at 10:30 am, instead of the regularly-scheduled family Planetarium program. Have fun with the Sun, marvel at the Moon, find your favorite star, become friends with the night sky!

The favorite tool of astronomers was invented 400 years ago. We'll see how much bigger and more powerful telescopes are now than they were back then.

In 1609 Galileo pointed the newly-invented telescope to the skies and beheld unexpected wonders. This year we're celebrating his astonishing discoveries in the first ever International Year of Astronomy. What did Galileo see? Come and find out.

Please note: On Nov. 7 and Dec. 5 "Star Babies" will be offered at 10:30 am instead of this program. Star Babies gives children 2 and younger a gentle, 15-minute introduction to the planetarium and the wonders of the night sky.

This is the last good chance this season to see the four moons Galileo discovered swinging around Jupiter 400 years ago. While we're at it, we'll take a look at nearby Neptune (have you ever seen it?).

On these special days, enjoy Planetarium shows throughout the day—at 10:30 am, 12:30 pm, 2 pm and 4 pm, with a children's show at 11:30 am and 3 pm.

Is there any chance of life on Mars today? How about long ago? We'll explore the possibilities.
