This Planetarium, on the grounds of University of North Carolina at Chapel Hill, was an interesting visit. Here I took in 3 different shows and learned more about the “beyond.”
The facility has trained 62 astronauts in the theater where planetarium shows are currently held. Here Neil Armstrong, Buzz Aldron, Michael Collins, and John Glenn sat investigating the stars to assist with navigation just in case the computers failed. During Gordon Cooper’s flight systems did fail and he relied on his celestial training to realign the space ship.
- Stars are different colors with blue being the hottest, and red the coolest.
- The Earth is closest to the Sun in January, and farthest away in July.
- An elliptical path is followed around the Sun by Earth.
- There is only one star in our universe. That star is the Sun.
- The Sun has shown on the Earth for 4 1/2 billion years.
- There are 200 billion stars in the Milky Way.
- The Milky Way was named by the Greeks for a goddess who dropped milk on the sky.
- Stars twinkle. Planets have constant light.
There are several shows at the Planetarium dedicated for all ages. My favorite was Carolina Skies as this was more interactive and the presenter informative and entertaining.
One final note, stop by the basement for a short exhibit on the 50th anniversary of the landing on the moon.
