Why Take This Course?

Astronomy A

Our universe is a crazy cool place. Delve into space in Astronomy A.

In 1859 North America woke up to a telegraph system gone mad. While telegraph stations throughout the world continued to function, many American stations, and miles upon miles of cables, no longer functioned. The people of North America had no idea that they had just been hit by a giant solar flare! This story shows us that ignorance of the universe subjects us to the universe’s temper tantrums. With black holes, gamma ray bursts, quasars, antigravity, missing energy, and a rapidly expanding perimeter, the universe is a scary-funky-cool place worth discovering. Come and join us as we take a closer look!

This is a two-semester science course students can take any time during their high school experience.
