Greetings, Earthlings! You are about to embark on a journey to our neighbor worlds in the cosmos! Astronomy 25 is an introductory-level course; which concentrates on the concepts of stars, galaxies, black holes, and the Big Bang Theory.

UNITS: 3

PREREQUISITE: None

The course has no astronomy, physics, or math prerequisites; however, knowledge of basic high school algebra is sometimes helpful.

COURSE DESCRIPTION

This course is an introduction to the universe and its history. The main focus is on our view of the heavens and how astronomers learn about stars and galaxies. The formation, life histories, and fates of different kinds of stars, including the sun, are examined. Exotic stars as well as black holes are explored. The structure and distribution of galaxies are discussed, with a focus on our own Milky Way Galaxy. The possibility of simple and intelligent life in the Milky Way Galaxy will be examined. The history of the universe, starting with the Big Bang is also investigated.

Let's have some fun with ASTRONOMY!

Group work

Groups will be assigned randomly for discussions. You have to communicate with groupmates using google docs or google slides to finalize your assignments.. Each student should submit the assignments through his/her CANVAS account. Failing to submit an assignment individually could lead to a zero credit for that work.

Ranking Tasks
