Discovering how life on Earth came to be; the possibility that life on Earth come from another planet.
Our Moon is stranger than you think, and we reveal its incredible secrets. Can we thank the Moon for life on Earth? What explains the mysterious tunnels beneath its surface? Is a lunar base the key to humanity's future in space?
For years, scientists suspected that the oceans came from molecules delivered to Earth from distant stars by asteroids, but a new discovery suggests that their true origins may be more exotic.
Scientists attempt to understand how this strange force of magnetism works.
A countdown of discoveries that changed everything known about the universe.
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.
Pluto is the subject, with an investigation into whether the planet has an underground ocean. 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.
Exploring the real-life Death Stars in the cosmos that could snuff out Earth without much effort; the science of the destructive power behind six of the deadliest star; vampire stars; supernovas; rogue stars.
The deadliest spots in the cosmos are explored.
The evolution of life on Mars before a series of cataclysmic events transformed the planet from a watery world to a hostile one; scientists believe life will find a way to continue despite the setbacks.
Dark matter is the biggest mystery of the cosmos. Scientists know that it has been vital to the universe since its birth, and new discoveries reveal that it could create black holes, cause mass extinctions, and might even shape life on Earth itself.
New discoveries are challenging everything we know about black holes, and astronomers are beginning to question if they even exist. The latest science tries to explain how they work and what they look like, despite the fact we've never actually seen one.
Planets that orbit two suns instead of one might be deadly hell worlds, but new discoveries reveal that sci-fi star systems with binary stars might be optimal places for alien life.
Our solar system hides a dark and violent past, and new discoveries reveal that the earth and planets were formed from the destruction of strange alien worlds that came before us.
The Milky Way is dying, and experts are investigating what's killing it.
Uranus and Neptune are mysterious, icy worlds at the edge of the solar system; new discoveries reveal that these strange planets may have helped start life on Earth.
Mercury is a deadly world, facing attacks from the sun, comets, and other planets, and even though it's the smallest planet in the solar system, it has a dangerous secret a dangerous secret that might one day threaten life on Earth.
Quasars are the brightest and most powerful objects in our universe, and though they have shaped the cosmos, they might ultimately destroy everything that exists.
Neutron stars are strange and violent phenomena that defy the laws of physics, and new discoveries reveal that these bizarre nightmares are far more deadly than we ever thought, with the power to destroy planets and even other stars.
Supernovas are the violent death of giant stars, and new discoveries reveal that these cataclysmic events create the elements that are essential to all life in the universe.
Interstellar space is the space between the universe's stars and new discoveries reveal that it's not empty and unremarkable as previously thought, but filled with weird objects and strange phenomena that might hold the darkest secrets of our cosmos.
Black holes are not the violent monsters people think they are, and new discoveries reveal that they might have been essential to creating stars, giving light, and building the universe itself.
Nebulas are the strange structures of cosmic gas and dust where stars are born and die, and new discoveries reveal the secrets of these mysterious places.
New discoveries are causing astronomers to question if the Big Bang really happened, and using the latest science, they investigate if it wasn't just the start of our universe but many mysterious multiverses.
Dark matter and dark energy are locked in an epic battle for control of the cosmos, and the winner will determine the fate of the universe. New discoveries might reveal which force will emerge victorious.
The latest discoveries suggest life beyond this planet; scientists investigate if earth's life began elsewhere in the universe, and whether humans need to evolve to know for sure.
New discoveries have revealed thousands of exoplanets beyond our solar system. Some resemble earth enough that one could be a new home for humanity. Even with cutting-edge technology, finding the perfect one is the scientific challenge of the age.
For twenty years, NASA's Cassini spacecraft revealed the strange secrets of Saturn until it vaporized in its atmosphere in a blaze of glory. But today its legacy lives on, as fresh data from the probe helps scientists make brand-new discoveries.
We owe our existence to the stability of earth's orbit. But we are the freaks: everywhere else we look we find orbits are chaotic, unstable, and violent. Yet on the very largest scale, orbits are also a creative force, even constructing the fabric of the universe itself.
