From the start of fusion in a star's core to the ultimate fate of the universe, unlock the workings of the cosmos.


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.
