For years they were only speculation, now modern astronomy is proving them frighteningly real and showing that they may well shape everything we see. The evolution of galaxies, from clouds of cold gas floating in space 13 billion years ago, to the vast gravitationally bound systems of today.
Examining the birth of stars, and how their creation changed the cosmos for ever, leading to planets and life itself. Stars are not eternal; they are dying in unimaginably large explosions called supernovas.
Second only to the Big Bang, these explosions are where creation and destruction meet. Only now have we begun to understand how these wonders in our sky work. There are just eight planets in our solar system, but there could be a hundred billion planets in our Milky Way galaxy alone. This show follows the journey of planets as they grow from grains of dust to the magnificently diverse worlds we see today.
Is our solar system unique? Since the first discovery of a planet orbiting another star, some alien solar systems have been identified. It's only by looking at solar systems far beyond our own, that we can understand how remarkable our universe is.
Moons come in every possible shape and size. Home to incredible natural phenomena like gigantic geysers and colossal volcanoes, moons also offer perhaps the best chance of finding alien life in the Universe - and they probably exist in the billions. Are we alone in the Universe? What makes Earth so different? Part of the answer is our volcanoes.
Today we are discovering volcanoes on alien worlds. Are these worlds where, tomorrow, we might find life? Destructive weather forces are symptoms of Earth's creative energy. In our quest to discover if we are alone in the universe, we shouldn't just look for worlds, we should look for weather; find that megastorm, and maybe we will find alien life.
We once thought that the only planets were in our solar system. We have found many other planets but they are nothing like we expected, from deep-frozen, toxic snowballs, to scorched and boiling nightmares. Is every planet out there a planet fom Hell? The Universe is a magnetic minefield. Spinning star systems crackle and explode, magnetic monsters rip worlds apart, star-quakes shoot beams of devastating energy, and galactic flamethrowers fire gamma-rays half way across the Universe.
Will we find Earth in the firing line? 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. As time machines from the early universe, comets could hold the key to unlock the secrets of the cosmos, and may even be the origin of life itself.
In this episode, we learn that comets are even more mysterious and fascinating than we had ever imagined. Asteroids wiped out the dinosaurs and may be back for us but they also built the Earth and may have brought life to its barren surface. Asteroids will shape our future as much as our past and scientists are striving to unlock their secrets.
The Earth was formed by a series of cataclysms without which we would not exist. Could the same events have created other earth-like planets elsewhere in the Universe inhabited by creatures like us? 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 , mile battle against gravity and magnetism, and its escape from the solar surface.
How and when will the Universe end? Gravity and dark matter are poised to annihilate the Universe in a big crunch. Our solar system hides a dark and violent past, and new discoveries reveal that Earth and the planets were formed from the destruction of strange alien worlds that came before us. The Milky Way is dying, and using the latest science and discoveries, experts are investigating what's killing it. Uranus and Neptune are mysterious, icy worlds at the edge of our solar system, and new discoveries reveal that these strange planets might 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 our 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. Our solar system is home to hundreds of strange, tiny worlds called dwarf planets, and new discoveries reveal the secrets of these mysterious places.
Scientists are using cutting-edge technology to stop an asteroid apocalypse, and for the first time, mankind is closer than ever to keeping Earth safe from these killer space rocks. Spacetime is the secret structure that controls our universe, and this strange four-dimensional substance controls time, light, and energy.
It will also determine how our universe will end. Parental guidance. S9, Ep3. Cutting-edge discoveries about the sun challenge everything known about its atmosphere. S9, Ep4.
