Into the Universe: Mysteries of the Cosmos

From Galileo to Einstein to Hubble, scientists have long grappled with the shape and scale of the Universe. As technology expands our view, missing space curvatures and inconsistent data related to Hubble's constant keeps us mystified. Is the universe flat, infinite, or bubble-shaped? How can the observable Universe be expanding but also homogenous? How do we explain the Big Bang if time itself is infinite? And do the answers to our questions live at the subatomic level?

Hidden in plain sight are astronomic marvels able to rip space and time to shreds; what's theoretical becomes the reality with the first black hole image, but much remains unknown; how do black holes form and do they create galaxies?

Stars can burn for billions of years but all will inevitably die; exploring why some gently dim but others explode; scientists study supernovae to unlock our cosmic history.

Billions of years ago, the first sign of life emerged on Earth; how exactly did this miraculous event unfold? As we probe the past, astronomers turn their telescopes to exoplanets to uncover vital clues about our own origins on planet Earth.

From dark matter to black holes, stellar explosions to the absence of alien life, this mind-bending season will explore some of the universe's greatest enigmas.

In 1950, physicist Enrico Fermi famously asked, "Where is everybody?"; in such a vast universe, how could life exist only on Earth? This existential query has fueled decades of debate, conjuring visions of alien worlds.
