It has long been thought that our universe is all there is, but it is possible we may live in just one of many.
For most of the Earth's history, life consisted of the simplest organisms; but then something happened that would give rise to staggering diversity, and, ultimately, life as complex as that which we see today. Scientists are still struggling to figure out just what that was.

Understanding what consciousness is, and why and how it evolved, is perhaps the greatest mystery known to science.

The equations of physics suggest time should be able to go backwards as well as forwards. Experience suggests, though, that it cannot. Why? And is time travel really possible?

Does life exist anywhere else in the universe? And how did it get started? Scientists are seeking the answers in the cosmos, our solar system and right here on planet Earth.

The Earth, the sun, the stars, and everything we can see, only comprise five percent of the universe. But what about the other 95 percent? Scientists are puzzling over dark matter and dark energy, the mysterious components that make up the rest.

The gender pay gap is not caused by women earning less than men for the same job. It is largely because women choose different careers and suffer a “motherhood penalty”’.

The Andromeda galaxy is heading straight toward our own Milky Way. The two galaxies will inevitably collide. Will that be the very last night sky our solar system witnesses?

Brilliantly narrated by film and television legend Sir Patrick Stewart, Journey To Space gives a sweeping overview of humanity’s accomplishments in space, as well as our ongoing activities and future plans. Journey To Space puts into historical context the magnificent contributions made by the Space Shuttle program and its intrepid space pioneers. It uses the most spectacular space footage – including unique views of Earth and operations in space – such as deploying and repairing the Hubble Space Telescope. It then goes on to show how the shuttle launched and assembled the International Space Station (ISS). Together, these programs have taught us how to live, build and conduct scientific experiments in space. The ISS will continue operating in space until 2024, and the film shows how it is building a foundation for the next giant leaps into space, concluding with a fascinating, realistic scenario of how astronauts will actually get to Mars, live there for long durations, and then return home after a two-and-a-half-year mission.

Covers 1964-1968, four heady, dangerous years in the history of the space race, focusing on the events surrounding the Apollo 1 and Apollo 8 missions. As Americans moved through the 60s and reflect on the challenges ahead, many begin to wonder: What exactly is it going to take to beat the Soviets to the moon?
