The universe consists of over \(100\) billion galaxies like ours, each containing tens or hundreds of billions of stars. This course will highlight what we know (and what is still unknown) about this vast and varied frontier.
Despite its incomprehensible size, the universe is remarkably similar in every direction. The stars near us appear to evolve in a similar way to those farther away, providing us with predictable markers for gauging scale.
Throughout this course you will discover a world of cosmic wonders, following a star from diffuse nebula to dense star remnant, traversing the scales of space and time from planetary to intergalactic, and crunching data to determine the universe's ultimate fate.
What is this?
A collection of interactive quizzes that illuminate the fundamental physics of the cosmos and the basic principles of astronomy, written by experts and guided by Brilliant's Principles for Learning.
Who is this for?
This course is for people looking to build their physics problem-solving skills while exploring the structure and contents of the visible universe.
About 30 quizzes, containing over 250 carefully crafted guided problems and explanations. It will take approximately 10-20 hours to complete.
Gear up with the basic physics tools that astrophysicists use to understand the universe.
Here we develop meter sticks to measure the cosmos, starting with insights from the ancient Greeks.
Everything on Earth is made of the remnants of stars. Find out how stars consume matter as they live and die.
Is extraterrestrial life possible? Could we live anywhere other than Earth? We don't know yet, but we're looking.
The fate of our universe is decided by matter we cannot see. Its identity is one of the great mysteries of our time.
