How the Universe Works - Season 9

Journey to the heart of the M87 supermassive black hole, the first and only black hole ever photographed, and explore the mystery of how it grew so large, what lies inside, and how it controls the entire galaxy. 

The Rosetta mission with its lander, Philae, is a groundbreaking expedition to land on a comet (Comet 67P) for the very first time; special access reveals what this cutting-edge journey discovers and how these mysterious objects help create life on Earth. 

A brand-new NASA mission to the sun reveals cutting-edge discoveries about Earth's star; as the Parker Solar Probe dives through the sun's atmosphere, its findings challenge everything known about this strange place.

The hidden kingdom of microscopic alien organisms shapes the universe as much as galaxies, stars, and planets; new discoveries reveal how bacteria, viruses, and other micro-organisms built life on Earth and influence humanity's future in the cosmos.

White dwarfs are small, dead stars with a dangerous side, capable of exploding into supernovas and destroying planets; new research suggests these mysterious phenomena may be the key to understanding the universe itself.

Galaxies are locked in continual combat across the universe, and our own Milky Way will face its biggest opponent ever, the Andromeda Galaxy, in a titanic and deadly struggle that could create a new and unrecognizable super galaxy. 

Our galaxy is full of stars ready to explode into supernovas, a stellar detonation powerful enough to destroy all life on Earth; it's an event that hasn't occurred in 400 years, and the search is on to locate which star may be next. 

Neutrinos are the most mysterious particles in the universe, and they power some of the most explosive events in the cosmos; new discoveries reveal how these ghosts pass through objects undetected and why they could be the reason we exist. 

New discoveries reveal an astonishing supermassive black hole that was born during the earliest days of the cosmos, and finding out how this giant grew so large so quickly may help to explain the very formation of the universe itself. 

Gravitational waves are helping scientists explore the cosmos in revolutionary, new ways, and the discoveries they make are revealing the universe's greatest mysteries. 

An explosion in the discovery of exoplanets is challenging everything we know about our universe; experts use cutting-edge astronomy to investigate these mysterious alien worlds and how they defy the laws of physics.
