Crash Course Astronomy Marathon • Full Series

From the creator

In Crash Course Marathons, we’re revisiting the series you love, in long-form videos that cover entire subjects from back to front. Crash Course Astronomy covers outer space, from the stars and nearby planets we can see with the naked eye, to the mysterious dark matter no one can see at all. With detours to exoplanets, deep time, and even our own planet Earth, we’ll explore the universe — what we know, how we know it, and what’s still left to discover.
