The Most Relaxing Facts About Astrophysics to Fall Asleep To

In this calm and sleepy facts episode, we explore the vast science of astrophysics... the discipline that reads the universe's deepest secrets in nothing more than light. We trace the history of telescopes from Galileo's first lens to the James Webb Space Telescope's golden mirrors, and learn how astronomers split starlight into spectra to identify the exact elements burning inside stars millions of light years away. We follow the life cycle of a star from its quiet birth inside a collapsing nebula to the spectacular supernova that scatters heavy elements across space. We bend spacetime with Einstein, fall past the event horizon of a black hole, and explore the mystery of dark matter and dark energy... the invisible forces shaping 95% of the universe. Along the way, we meet neutron stars dense enough to crush a mountain into a sugar cube, pulsars spinning hundreds of times per second, and the cosmic distance ladder that lets astronomers measure the size of everything that exists. Let these 500 calm, fascinating facts about astrophysics carry you gently to sleep.
