Discoveries about interstellar space, the space between the universe's stars, 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 the 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 that we might be on the verge of discovering life beyond our planet, and scientists are investigating if earth's life began elsewhere in the universe, and whether we need to evolve to know for sure. New discoveries have revealed thousands of exoplanets beyond the 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. 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.
NASA is on a mission to send humans to Mars within just 15 years, but to reach this next frontier of space exploration, experts must discover new technology and cutting-edge science that protects astronauts from the Red Planet's deadliest killers. The discovery of extraterrestrial life might face an impossible challenge: the physics of the universe itself; but using cutting-edge tech, experts might be on the verge of a groundbreaking find -- and the evidence could already be in hand.
Our universe's stars are dying off faster than new ones are born, and using the latest technology, experts investigate the secrets of the last stars of the cosmos and what this stellar apocalypse means for life on earth. A look at the concepts behind changing the way we travel through the space-time continuum, and how extreme speed and extreme gravity can change the rules of the game.
As this mighty probe is pummeled with deadly radiation, it gathers new data that could change everything we know about the solar system's biggest planet. We don't yet know where the edge of the universe is or what happens there; but thanks to cutting-edge technology and new discoveries, experts might finally reveal the secrets of the phenomena that can be found in deepest reaches of the cosmos.
The center of the Milky Way is home to strange and deadly phenomena that we don't yet understand, but using the latest science, experts are revealing how the supermassive black hole our galaxy's core shapes life on Earth.
