0.0European Space Agency astronaut Alexander Gerst and his NASA colleague Reid Wiseman are launched into space from the Baikonur Cosmodrome in Kazakhstan. Gerst and Wiseman spend six months in humanity's outpost in space and film many of their activities.
7.2At the edge of our solar system supposedly lies an immense planet. Five to ten times the size of the Earth. Several international teams of scientists have been competing in a frantic race to detect it, in uncharted territories, far beyond Neptune. The recent discovery of several dwarf planets, with intriguing trajectories, have put astronomers on the trail of this mysterious planet. Why is this enigmatic planet so difficult to detect? What would a ninth planet teach us about our corner of the universe? Could it help us unlock some of the mysteries of our solar system?
6.9The first feature from Alison McAlpine is a dialogue with the heavens—in this case, the heavens above the Andes and the Atacama Desert in northern Chile, where she alights on the desert- and mountain-dwelling astronomers, fishermen, miners, and cowboys who live their lives with reverence and awe for the skies.
7.6Archival material from the original NASA film footage – much of it seen for the first time – plus interviews with the surviving astronauts, including Jim Lovell, Dave Scott, John Young, Gene Cernan, Mike Collins, Buzz Aldrin, Alan Bean, Edgar Mitchell, Charlie Duke and Harrison Schmitt.
6.0Billions of years ago, Venus may have harbored life-giving habitats similar to those on the early Earth. Today, Earth's twin is a planet knocked upside down and turned inside out. Its burned-out surface is a global fossil of volcanic destruction, shrouded in a dense, toxic atmosphere. Scientists are now unveiling daring new strategies to search for clues from a time when the planet was alive.
0.0This feature-length documentary is a portrait of eclipse chasers, people for whom solar eclipses - among nature's more spectacular phenomena – are a veritable obsession. The film follows 4 of them as they travel incredible distances to witness the last total eclipse of the millennium as it sweeps eastward across Europe to India. At various points along the way enthusiasts Alain Cirou in France, Paul Houde in Austria, Olivier Staiger in Germany and Debasis Sarkar in India offer their impressions of the historic event.
10.0Cave paintings and lunar calendars exist in the caves and remains of prehistoric hunters studied recently. What if Prehistoric Man were clever enough to develop in depth scientific knowledge? As unlikely as it may seem, new data tend to prove that Prehistoric Man actually invented Astronomy!
8.0Chaco Canyon, located in northwest New Mexico, is perhaps the only site in the world constructed in an elaborate pattern that mirrors the yearly cycle of the sun and the 19-year cycle of the moon. How did an ancient civilization, with no known written language, arrange its buildings into a virtual celestial calendar, spanning an area roughly the size of Ireland?
10.0For over three decades, NASA and an international team of scientists and engineers pushed the limits of technology, innovation, and perseverance to build and launch the James Webb Space Telescope, the most powerful space observatory ever created. Cosmic Dawn brings audiences behind the scenes with the Webb film crew, and never-before-heard testimonies revealing the real story of how this telescope overcame all odds.
0.0Part of the Almost Famous series. Jocelyn Bell was a graduate student at Cambridge in 1967 when she pushed through the skepticism from her superiors to make one of the greatest astrophysical discoveries of the twentieth century. While Jocelyn was belittled and sexually harassed by the media, the Nobel Prize was awarded to her professor and his boss.
7.2New planets are now being discovered outside our solar system on a regular basis, and these strange new worlds are forcing scientists to rewrite the history of our own solar system. Far from a simple story of stable orbits, the creation of our solar system is a tale of hellfire, chaos and planetary pinball. It's a miracle our Earth is here at all.
7.0For 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.
0.0Computer animation and footage from NASA space missions explain how our solar system evolved and the place Earth has within the system.
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.
A documentary charting the rigors of the Russian space program, where the symbol of national pride would justify the most demanding training conditions.
6.5Nowadays we associate Johannes Kepler with his famous laws of planetary motion. But the history of his discoveries is a drama of Shakespearian proportions - full of intrigue, passion, depravity and corruption.
0.0The loss of the Bill E. Gordon radio telescope has left a void in the world of radio science, the mountains that cradled it, and the hearts of many visitors and enthusiasts who appreciated the beautiful engineering marvel. It’s a difficult time for the scientists and those who grew up seeing the telescope every day in the fields of atmospheric science, planetary science, and Radio astronomy. Experience the legacy of a 57 year journey, from the small island of Puerto Rico to the deepest regions of the galaxy with the world's most powerful telescope.
