The nighttime sky in this photo appears to contain only stars, which belong to the Milky Way. However, upon closer inspection we find a variety of objects, such as planets, stars, nebulae, and galaxies. Despite their distance, each of these objects impacts our existence here on Earth. Galaxies provide a place for stars to develop. Nebulae provide the materials to form stars. Stars, like the Sun, provide energy and create elements. Stars formation often results in the formation of planets.
In this unit, students are introduce to the universe beyond Earth and the relationships between planets and moons, and stars and galaxies.
