Space's Deepest Secrets

From the mission that saw Pluto for the first time to the Mars rovers, a new breed of explorers risk their careers, and even their lives, to lead humanity to worlds we have never seen and tackle the mysteries of life itself.

Meet the scientists across the world on the hunt for Dark Energy, an unknown form of energy which is hypothesized to permeate all of space and may be accelerating the expansion of the universe. World scientists are searching for Dark Energy, the biggest challenge of physics. In Europe, a multi-billion dollar satellite will map the sky from space.

An exploration of the dramatic fate of our future descendants, the technology they'll need to survive the end of this world billions of years from now and our options for colonizing and starting again on a new planet somewhere far from Earth.

A soaring quest through the solar system's exotic and hidden water realms, from the deep seas below the icy crust of Europa to the vast prehistoric oceans that once existed on Mars billions of years ago. Using 3D graphics to explore the icy wastes of Europa and the vast prehistoric oceans of Mars.

Thirty-five years after leaving Earth, the Voyager spacecraft is going to leave the Solar System to tell the incredible story of a mission that was only supposed to last five years but is still going today.

The story of how a large aerospace company, BAE Systems, began a secret project to counter the force of gravity while NASA simultaneously ran a similar 'Breakthrough Propulsion Physics' program.

The future of space travel is under attack, and it's because of millions of pieces of debris from old satellites and space missions that orbit Earth. Go inside the effort by the US government and others to combat and clean-up the lethal threat of space junk.

A team of scientists searches the universe to find the oldest stars, born just after the Big Bang.

A team of scientists is looking for the very first stars in the universe, which were born moments after the Big Bang and gave creation the earliest ingredients for life. Go inside this groundbreaking quest for this pivotal moment.

When the sun flares up, billions of tons of superheated gas and intense radiation are propelled toward Earth; experts are trying to predict what is coming toward the Earth and how to prepare for this threat.

An in-depth look at how NASA is preparing for its most ambitious and dangerous mission yet: to land a human being on the surface of Mars.

The discovery of exoplanets pushes scientists to reexamine the origin of the Solar System; the evidence infers a tale of unrestrained collisions and chaos.

Scientists are working to determine if parallel universes exist.

Scientists are finally on the hunt to finally crack the dark secrets of the atoms that make up the universe. The scientific quest to crack the secrets of the universe is detailed. Included: whether the rules of physics will need to be rewritten further considering WIMPs (Weakly interacting massive particles) as dark matter particles and other dark matter theories.
