Mars, you'll find it as a reasonably bright reddish light in our south-western sky this fall, and is more like planet Earth than any of the other planets in our Solar System. With some of the largest geographical features in the Solar System, we'll learn about its similarities to Earth, more so in the past than now. NASA is now designing a spacecraft to carry astronauts to the red planet. Follow with us as we tour Mars and investigate the roadblocks facing those who would attempt to colonize the red planet.

Our current public show “The Moon” has only two more weekend to go. This show covers many of the commonly asked questions about the Moon, such as what causes the monthly phases of the Moon and why we never see the back side of the Moon. However, did you know that the Moon does not just orbit around the Earth each month? We may realize that the Moon is the predominant cause of Earth’s tides, but did you realize that the Moon is also slowing down the Earth’s rotation causing our day to become longer; and how long would you guess it takes the Moon to slow Earth rotations such that it adds one-second to our day? You may know that our seasons do not change because of the Earth’s annual orbital distance variation from the Sun, but did you know that the Moon is a major factor in our weather; how can this be?? Find the answers to these and other interesting questions about our nearest neighbor in space, the Moon.

Typically two volcanoes erupt on planet Earth every day and they can be deadly; on average some 800+ deaths occur each year due to volcanic activity. Yet, volcanoes are the life blood of geologically live/active planets and moons. In this show we'll learn about volcanoes: what causes them, types of volcanoes and eruptions here on planet Earth. We'll also look at volcanic activity on other worlds in our solar system such as found on Venus, Mars, a moon at Jupiter, and other bodies in our solar system.

Our star, the Romans named it Sol; today we know it as the Sun. How often, though, do we think of it as a real but very near star? In this show we will learn about the formation of the Sun, what's inside our star, why it shines, what its future is, and how it compares to other stars in our galaxy and beyond. We will also cover sunspots, solar prominences, solar flares, mass coronal ejections, solar eclipses, and the aurora-producing solar wind.
