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. 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.

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.

Time travel might be more possible than we ever imagined, and today, cutting-edge technology and the latest research into black holes and wormholes are helping experts get steps closer to discovering how to travel through time.

NASA's Juno spacecraft is part of a cutting-edge mission to explore the mysteries of Jupiter, and 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. Still, thanks to cutting-edge technology and new discoveries, experts might finally reveal the secrets of the phenomena that can be found in the 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.

Earth's journey through the universe is a perilous one, and new discoveries reveal that our planet is heading toward a mysterious area of the cosmos that could eject us out of the Milky Way and into oblivion.
