The new discovery of seven alien Earth-like planets in a faraway solar system is a major milestone in our hunt for extraterrestrial life, and experts investigate the secrets of TRAPPIST-1's mysterious worlds to reveal if we're truly alone in the universe.
2018 • Astronomy
Shocking new evidence has convinced some of the world's greatest physicists that the universe is a hologram. Using cutting-edge technology, they investigate the secrets of black holes and space-time to build the case for this game-changing discovery.
2019 • Astronomy
A spacecraft captures the first close-up images of the dwarf planet Pluto. Space's Deepest Secrets shares stories of the men and women who pushed their ingenuity and curiosity to uncover some of the most groundbreaking findings in the history of space exploration.
2020 • Astronomy
Astronauts have detected a mysterious region of space that's dangerous for reasons they have yet to understand, and scientists believe the long-term effects of this danger zone may have implications for the future of humanity both in space and on Earth.

We’ve covered a lot of incredible stuff, but this week we’re talking about the weirdest objects in space: BLACK HOLES. Stellar mass black holes form when a very massive star dies, and its core collapses. The core has to be more than about 2.8 times the Sun’s mass to form a black hole. Black holes come in different sizes, but for all of them, the escape velocity is greater than the speed of light, so nothing can escape, not matter or light. They don’t wander the Universe gobbling everything down around them; their gravity is only really intense very close to them. Tides near a stellar mass black hole will spaghettify you, and time slows down when you get near a black hole — not that this helps much if you’re falling in.
When a team of scientists have launched a space probe to the heart of our solar system in brand-new mission to our Sun, it makes fresh discoveries reveal how it works; along the way, experts uncover a surprise find on Mercury.
The first episode of Space Voyages looks at the Mars Curiosity Rover - an incredible 21st century machine. And it would never have been possible without the accomplishments of early NASA astronauts and engineers. Everything was new – rocket science, astronaut survival – even simply steering in space! This is the story of how both humans and robots laid the foundations for space exploration that continues today.
