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?

Starting with a grand tour of the Solar System, powerfully told by the world’s top space scientists. From the raging inferno of the Sun to the icy beauty of Pluto, discover the secrets that the planets have kept for billions of years, revealed with stunning images from space.
Professor Brian Cox explores the powerhouse of them all, the sun. In India he witnesses a total solar eclipse and in Norway, he watches the battle between the sun's wind and Earth, as the night sky glows with the northern lights. Beyond earth, the solar wind continues, creating dazzling aurora on other planets.
Our first steps into space were leaps into the unknown. Outer space is still the most hostile environment ever encountered, but someday, we may be forced to leave earth in order to save our species. The question now is whether human ingenuity can overcome the human body’s limitations.
Voyager has had a profound effect on our knowledge of the cosmos. Its mission was supposed to last five years but remains ongoing, fundamentally changing our understanding of the solar system. Featuring contributions from key scientists, we’ll explore what’s been achieved and what happens next.
