Nasa: Build a Telescope

High schoolers read about the Spitzer Space Telescope and the technology used to learn about planet composition. They calculate the radius of a planet, the size of a planet, the average density of a planet and the likely core composition...

Students construct an interferometer using a simple telescope. In this physics lesson, students explain how light waves create the fringe patterns. They observe patterns made by different objects in the sky and compare them.

"Europa’s ocean is considered to be one of the most promising places that could potentially harbor life in the solar system,” said Geoff Yoder, with NASA’s Science Mission Directorate. Show a video that shares four surprising facts...
