Venus: Death of a Planet (2021)
Billions 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.

Passage of Venus (1874)
Photo sequence of the rare transit of Venus over the face of the Sun, one of the first chronophotographic sequences. In 1873, P.J.C. Janssen, or Pierre Jules César Janssen, invented the Photographic Revolver, which captured a series of images in a row. The device, automatic, produced images in a row without human intervention, being used to serve as photographic evidence of the passage of Venus before the Sun, in 1874.

Chasing the Equinox (2019)
The ancients hid the secrets of their incredible knowledge of astronomy in their temples and palaces, built to align with the sun, on the same day, all over the world. Revealing our species' obsession with the sun, across thousands of years and every continent, this is architectural magic on a cosmic scale.

400 Years of the Telescope (2009)
A documentary chronicling the history of the telescope from the time of Galileo. Featuring interviews with leading scientists discussing Galileo's first use of the telescope to the latest discoveries in cosmology.
Astronomy for You (1959)
A series of programs designed for the adult layman who has a curiosity about the skies and the makeup of the universe in which we live. The terms used during the series are fully explained and materials from a number of great observatories and institutions of learning are used for visual illustration. It begins with the solar system and works outward, stimulating interest in this area and awakening a desire for further study and investigation.
Riding Light (2015)
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.

Hubble: Thirty Years of Discovery (2020)
For thirty years, NASA's Hubble Space Telescope has discovered new alien worlds, black holes, and the age of the universe itself; NASA astronauts reveal the secret history of the life-or-death missions to keep this complex machine working.

Prehistoric Astronomers (2007)
Cave 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!

The Sun and Man (2018)
The Sun was born way before Man existed. What exact role did the Sun play in the emergence of life and Mankind? When did Humanity identify it? Then deify it? At what point did Man want to understand it? When and how was the Sun used by Man? The Sun is everywhere and is the origin of everything. We are going to show that our culture, our daily lives, our society, our bodies and our lifestyles are all derived from the Sun and are dependent on the Sun. We will go back in time, go back in history to understand the relationship between Man and the Sun.

Nostalgia for the Light (2010)
In Chile's Atacama Desert, astronomers peer deep into the cosmos in search for answers concerning the origins of life. Nearby, a group of women sift through the sand searching for body parts of loved ones, dumped unceremoniously by Pinochet's regime.

A Message to the Stars (2021)
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.

Mauna Kea: Temple Under Siege (2005)
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.

Who's Out There? (1975)
Orson Welles — with contributions from scientists George Wald, Carl Sagan, and others — examines the possibility and implications of extraterrestrial life. In examining our perceptions of alien 'martians' from his "War of the Worlds" broadcast, to then-modern explorations of Mars, this film from NASA provides a unique glimpse at life on earth, and elsewhere in the universe.
