Earth & Space Science
You will get to learn the basic principles of space science. Explore Newtons third law by setting your own celestial objects in motion while trying to avoid fiery collisions, not to mention also rescuing an astronaut on a space mission!
After completing this tutorial, you will be able to complete the following:
What are telescopes, and when were they invented?
~ Telescopes are tools that magnify images of far-away objects and, with today's models, use long-term exposure to capture images of distant, weaker lights. They were first invented in the seventeenth century.
What are the two main types of telescopes, and how are they different?
~ The two main types of telescopes include optical and radio telescopes. Optical telescopes use mirrors or lenses to collect or refract the light from stars. Radio telescopes are designed to detect the radio waves emitted by stars.
How does a radio telescope work?
~ A radio telescope works by capturing the radio waves of stars with a concave dish. This dish reflects the incoming waves to a focal point in the receiver.
How is the size of a telescope related to its usefulness?
~ The larger a telescope is, the more powerful it will be, which means it can theoretically be used to observe more stars because it can see further into the distance.
