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.

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?

The first close-up images of Pluto revealed unimaginable secrets of this mysterious frozen world. Now, scientists investigate if Pluto is home to a warm ocean of liquid water beneath its surface, and whether this underground ocean could harbour life.
Cassini-Huygens has given us a more detailed account of Saturn than we could have ever imagined. Breathtaking images of Saturn and its sparkling rings, a massive 6-sided polar storm, and 62 moons - including the most bizarre worlds in our Solar System -- we have seen them all thanks to Cassini.
Last week we covered multiple star systems, but what if we added thousands or even millions of stars to the mix? A star cluster. There are different kinds of clusters, though. Open clusters contain hundreds or thousands of stars held together by gravity. They’re young, and evaporate over time, their stars let loose to roam space freely. Globular clusters, on the other hand, are larger, have hundreds of thousands of stars, and are more spherical. They’re very old, a significant fraction of the age of the Universe itself, and that means their stars have less heavy elements in them, are redder, and probably don’t have planets (though we’re not really sure).
In just one generation, our ability to search for planets beyond our solar system has transformed. With modern techniques and telescopes, planetary scientists have found thousands of exoplanets in our universe, and many of them have the perfect conditions for life. Are we about to find Earth’s twin?
