This artist's rendering shows a cross-section of the ice shell immediately beneath one of Enceladus' geyser-active fractures, illustrating the physical and thermal structure and the processes ongoi A new slide show highlights the Cassini spacecraft's third year at the ringed world. We can see the Moon from the Earth, because it is partially lit by the light from the sun. This is why we always see the same side of the Moon.

As the Moon orbits around the Earth once per month, the angle between the Earth, the Moon and the Sun changes; we see this as the cycle of the Moon's phases. The Islamic calendar is also based on the moon, and begins counting years from Prophet Muhammad's flight to Medina. The Madison Metropolitan School District Planetarium (MMSD Planetarium) provides immersive experiences for groups and public audiences bringing out-of-this-world concepts down to Earth.
