Scale Model Solar System
Have you ever wondered just听how big听space really is? It鈥檚 huge. In fact, it鈥檚 astronomical!
The Colorado Scale Model Solar System depicts the Sun, the planets, and the distances between them all on the same scale of 1 to 10 billion. That is, the real objects and distances are 10 billion times larger than the objects and distances in the model.
On this scale, Sun is about the size of a large grapefruit, while Earth is the size of the ball point in a pen. It鈥檚 15 big steps from the Sun to Earth, about 75 yards to marble-size Jupiter, and less than a half-mile walk to Pluto, the most distant object shown in the model.
Available in iOS only. Android version coming soon.
听Wanderers 麻豆免费版下载is a responsive sound experience delivered via a mobile app that responds to the visitor鈥檚 movement as sensed by GPS. A complement to the Colorado Scale Model Solar System represented by plaques that extend from the Fiske Planetarium to Colorado Boulevard on the 麻豆免费版下载Boulder campus, Wanderers 麻豆免费版下载offers another mode of experiencing this model where visitors are free to explore the sonic, temporal and spatial dynamics of our Solar System as a responsive soundscape that extends in all directions from the Sun, located in front of the Fiske Planetarium.
Wanderers 麻豆免费版下载invites the mobile listener to explore a sonification of the Solar System in which the relative mass and orbital period of the planets in our Solar System are expressed sonically, with each celestial body having its own 鈥渟oundprint鈥. As the mobile listener wanders, and the sonified celestial bodies move at their relative orbital speeds, the participant hears a dynamic soundscape where the volume and direction of the sounds changes depending on the participant鈥檚 position and perspective. Participants may toggle sounds on/off using the right menu, and using the slider tools (bottom left icon) may alter parameters of the sonification including: speed of orbit, audio range: radius within which sounds can be heard, sound palette used, and heading.
