Dark Matter in Spiral Galaxies

In this project the students will gain insight into why astronomers think there are large amounts of dark matter in galaxies. Dark matter is material that is “dark” in the sense that it neither absorbs nor emits electromagnetic radiation (“light”). We can infer its presence through the gravitational effect it has on the matter we can see (stars and gas).

Classification of the Universe

In this activity, the students will learn different ways of roughly separating the features of observable structures in the universe and will gain the tools needed for identifying what kinds of objects they can observe through telescopes when visiting the observatory.
