Asteroids strike, planets collide, black holes blast out death rays, volcanoes erupt and ice engulfs the planet. These are the universe’s weapons of extinction. They’ve happened before - wiping out entire species, and they will happen again. Are we next?

How does light escape from the sun? We take a journey from the centre of the sun, following the path of light. We witness its fiery birth from in the core, its 430,000 mile battle against gravity and magnetism, and its escape from the solar surface.

The only reason life on Earth is possible is because of our stable orbit around the Sun. Elsewhere in the Universe, orbits are chaotic, violent and destructive. On the largest scale, orbits are a creative force and construct the fabric of the Universe.

Orbits are the dynamics that drive the universe. From the smallest asteroid to the largest super-cluster, everything in the universe is in orbit. We owe our very existence to the stability of earth's orbit — it gave us life and keeps us safe. But we are the freaks. Everywhere else we look we find orbits are chaotic, unstable, and violent. Beyond our solar system we find planets that are blow-torched, stars that eat each other, and black holes that destroy everything in their path. Yet on the very largest scale, orbits are also a creative force. clashing galaxies give birth to new stars and new worlds. on the galactic scale orbits even construct the fabric of the universe itself.

The first second of the Universe, the creation of everything when space, time, matter and energy burst into existence. It is the most important second in history, which seals the Universe's fate and defines everything that comes after - including us.

Recent discoveries could explain how supermassive black holes grow so big, one of the universe's most mysterious questions. Neither dark matter nor cannibalism can fully explain these monsters, but the latest science might finally provide an answer.

Life once existed on Mars, but a series of devastating mass extinctions have made present-day life nearly impossible. The latest science shows how Martian life keeps bouncing back as it transforms from a watery world like Earth into a desert planet.

If a massive asteroid collides with earth, it could end life on our planet as we know it; new discoveries and cutting-edge tech reveal just how close we are to apocalypse and what it would take for the world's leading space agencies to stop it.

Dead stars may be the key to understanding the cosmos. New research proves white dwarfs are one of the driving forces of our universe. They eat planets, they flare out in high-energy light Have scientists finally discovered how these small stars could be such massive galactic players?

It is one of the most baffling questions that scientists can ask: how big is the Universe that we live in? Horizon follows the cosmologists who are creating the most ambitious map in history - a map of everything in existence. And it is stranger than anyone had imagined - a Universe without end that stretches far beyond what the eye can ever see. And, if the latest research proves true, our Universe may just be the start of something even bigger. Much bigger.
In summer 1969, Apollo 11 succeeded as the first manned mission to land on the moon. The next challenge was to design and build the first exploration vehicle. It had to allow astronauts to explore the moon's surface, but it had to fit in just a meter square space!
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.
Neil deGrasse Tyson sets off on the Ship of the Imagination to chase a single comet through its million-year plunge toward Sol. Later, Tyson visits the birth-place of Sir Isaac Newton and retraces the unlikely friendship between Newton and brilliant polymath Edmond Halley. It was Halley's patience and generosity which allowed Newton to conquer his fear of isolation and find the courage to publish his masterwork, "Principia Mathematica" which launched a scientific revolution.
Harvard professor and best-selling author, Dr. Lisa Randall, simplifies and expounds upon some of modern physics' most basic questions. What is dark matter and dark energy? What is the fundamental nature of space and time? What do we not know yet about the universe and its fundamental properties?
