Sci. Ch. How The Universe Works:

NASA is on a mission to send humans to Mars within just 15 years. Still, to reach this next frontier of space exploration, experts must discover brand-new technology and cutting-edge science that protects astronauts from the Red Planet's deadliest killers.

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.

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.

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.

New discoveries reveal the power of microscopic alien organisms. The discovery of extraterrestrial life might face an impossible challenge: the physics of the universe itself.

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.

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.

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.

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.

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.
