In a feast of colours and sounds, Mayan Archaeoastronomy: Observers of the Universe makes a tour of 6 Mayan temples: San Gervasio, Chichen Itzá, Uxmal, Edzná, Palenque and Bonampak where the spectator dives into a Mayan world of knowledge about the importance of the orientations of its temples in relation to the movement of some stars like the Sun, the Moon and Venus.

In our terrestrial view of things, the speed of light seems incredibly fast. But as soon as you view it against the vast distances of the universe, it's unfortunately very slow. This animation illustrates, in realtime, the journey of a photon of light emitted from the surface of the sun and traveling across a portion of the solar system, from a human perspective. Liberties were taken with certain things like the alignment of planets and asteroids, as well as ignoring the laws of relativity concerning what a photon actually "sees" or how time is experienced at the speed of light, but overall the size and distances of all the objects were kept as accurate as possible. It was also decided to end the animation just past Jupiter to keep the running length below an hour.

This series also covers the essential concepts of astronomy: gravity, the light spectrum, Earth's magnetic field, the solar system, the sun, Kepler's Law, the universal law of gravitation, the Doppler Effect, and much more!

How's it all gonna end? This experience takes us on a journey to the end of time, trillions of years into the future, to discover what the fate of our planet and our universe may ultimately be. We start in 2019 and travel exponentially through time, witnessing the future of Earth, the death of the sun, the end of all stars, proton decay, zombie galaxies, possible future civilizations, exploding black holes, the effects of dark energy, alternate universes, the final fate of the cosmos - to name a few.

A look at the Sun, the star that revolves at the center of the Solar System, and its representation in art throughout history.

Canada is leading the way when it comes to dark sky preservation and the fight against light pollution. See how dark sky preserves in Wood Buffalo, Jasper and Elk Island National Parks educate the public about the importance of protecting the night sky for the health of humans and wildlife. Then visit star parties in British Columbia and Alberta where amateur astronomers and astrophotographers watch and celebrate the night sky.

Although the mountain volcano Mauna Kea last erupted around 4,000 years ago, it is still hot today, the center of a burning controversy over whether its summit should be used for astronomical observatories or preserved as a cultural landscape sacred to the Hawaiian people. For five years the documentary production team Nā Maka o ka 'Āina ("the eyes of the land") captured on video the seasonal moods of Mauna Kea's unique 14,000-foot summit, the richly varied ecosystems that extend from sea level to alpine zone, the legends and stories that reveal the mountain's geologic and cultural history, and the political turbulence surrounding the efforts to protect the most significant temple in the islands: the mountain itself.

A radio astronomer receives the first extraterrestrial radio signal ever picked up on Earth. As the world powers scramble to decipher the message and decide upon a course of action, she must make some difficult decisions between her beliefs, the truth, and reality.

Three billion miles away a grand-piano-sized spacecraft is speeding through the outer solar system at nearly 1,000 miles per minute. After nearly a decade in space, the New Horizons space probe will have just 86 seconds to complete its primary mission: Discover the planet Pluto. This time-sensitive special will showcase the first quality pictures of Pluto that the probe will capture.

In an age when misinformation, alternative facts, and conspiracy theories have become mainstream, UFOs have risen to become one of the most-talked about pop culture phenomena. With all of this noise, how can we expect anyone to know how much of this is true? What is in our skies? What do we know, and how do we know it? And most importantly: Are we being visited?

For more than 50 years, we’ve been unsuccessfully searching for any evidence of intelligent extraterrestrial life. But, the discovery of thousands of exoplanets has meant the hope of finding them is higher than ever. If any messages could eventually be decoded and answered in any far, far away star, it could radically transform our consciousness as species and our place in the universe. A message from the stars changes life on Earth… forever.

Three teenage girls come of age while working at a pizza parlor in Mystic, Connecticut.

Man has always sought to seek further afield. After the seafaring explorers of the 16th century, 21st century cosmologists today navigate more celestial oceans, with each mission providing an ever-broader and more impressive cartography of our surroundings. At the avant garde of modern technology, these strange travellers are actually immobile, and their vessels are powerful and spectacular telescopes, on the Earth or in space, constantly widening the limits of our knowledge and giving form to our dreams of infinity. From Hawaii to Australia, via South Africa and China, we set out on an incredible scientific and human adventure to visit the planet's greatest cosmic exploration centres to discover the new challenges involved in understanding the universe. A journey on Earth and in the heavens that will take your breath away!
