For more than half a century, filmmakers have attempted to capture the mystery of unidentified flying objects. What began as fringe speculation in the 1970s has transformed into a global discussion about government secrecy, scientific inquiry, and the possibility of life beyond Earth. Across decades, documentaries have reflected society’s changing attitudes toward UFOs—sometimes skeptical, sometimes sensational, and sometimes startlingly credible.
Here’s a look at how UFO documentaries evolved from 1970 to 2025, told through ten of the best films to define the genre.
The 1970s–1990s: Seeds of Curiosity
The 1970s marked an era when UFO culture merged with television and documentary filmmaking. Programs like In Search Of… and BBC’s UFOs: The Real Story offered early treatments of the phenomenon, leaning heavily on speculation. While not as polished as modern films, these works laid the foundation for public interest in unexplained aerial phenomena.
By the 1990s, cases such as Roswell and Rendlesham Forest gained new traction, and UFO coverage began moving into mainstream documentary slots. This was the pre-internet era, when books and television specials shaped public belief.
The 2000s: UFOs Enter the Documentary Mainstream
1. Out of the Blue (2003)
Narrated by Peter Coyote, Out of the Blue became the benchmark for serious UFO documentaries. Featuring astronauts like Gordon Cooper and interviews with scientists, it reframed UFOs as worthy of rational investigation rather than tabloid material.

2. The Secret NASA Transmissions: The Smoking Gun (2001)
While more niche, this film dissected space shuttle footage that appeared to capture strange objects in orbit. It introduced the internet era’s fascination with raw “unexplained footage,” a trend that continues today.
The 2010s: Whistleblowers and Government Shadows
The 2010s were defined by growing distrust of institutions and increased interest in disclosure. Documentaries during this era reflected that climate—probing government secrecy, intelligence operations, and hidden archives.
3. I Know What I Saw (2009)
James Fox’s follow-up to Out of the Blue gathered credible testimonies from pilots, politicians, and military personnel. It helped legitimize eyewitness accounts and highlighted major incidents like the Phoenix Lights.

4. Mirage Men (2013)
A darker, more sobering film, Mirage Men proposed that many UFO stories may have been planted or manipulated by U.S. intelligence to conceal classified projects. It asked viewers to question not only UFO sightings but also the very narratives surrounding them.
5. Unacknowledged (2017)
Fronted by Dr. Steven Greer, this documentary argued that the government has suppressed UFO-related technologies for decades. Controversial but widely viewed, it reignited debates about disclosure in the age of digital activism.
6. Witness of Another World (2018)
Shifting away from conspiracy, this moving film explored the lifelong impact of an alien encounter on an Argentine man. Rather than focusing on governments, it humanized the UFO phenomenon by emphasizing personal experience.
The 2020s: The Age of UAPs
The release of U.S. Navy “Tic Tac” videos and Congressional hearings on UAPs (Unidentified Aerial Phenomena) sparked a new wave of documentaries—ones rooted more in official testimony than speculation.
7. The Phenomenon (2020)
Often called the definitive UFO documentary of its time, The Phenomenon compiled over 70 years of cases with interviews from top officials, including former Senate Majority Leader Harry Reid. It offered a comprehensive and credible account of the UFO mystery.

8. Ariel Phenomenon (2022)
This haunting film revisited a 1994 event in Zimbabwe where schoolchildren reported a mass sighting. Decades later, the witnesses—now adults—recount the emotional and cultural weight of their experience.
9. Moment of Contact (2022)
Set in Brazil, this documentary examined the infamous Varginha Incident, where locals claimed to have seen and even interacted with non-human beings. Its cinematic approach brought an international dimension to the UFO conversation.

10. The Age of Disclosure (2025)
Premiering at SXSW, this recent entry dives into what some call the modern “UFO disclosure era.” Featuring interviews with military and intelligence officials, along with political voices like Senator Marco Rubio, it suggests that an 80-year cover-up is unraveling before our eyes.
UFO Documentaries as a Mirror of Their Time
From grainy footage in the 1970s to today’s Pentagon reports, UFO documentaries mirror society’s shifting beliefs about authority, technology, and the unknown. Early films thrived on mystery, the 2010s questioned power structures, and the 2020s brought UFOs—now called UAPs—into serious policy discussions.
Whether one views these documentaries as entertainment, cultural history, or investigative journalism, together they chart humanity’s ongoing attempt to make sense of the skies.
✅ Final Thought: As the world enters what some call a disclosure era, UFO documentaries have moved from the fringes into mainstream dialogue. What was once mocked now sits at the intersection of science, politics, and philosophy—and the story is far from over.

Unlikely Collaborators is bringing astrophysicist Dr. Lisa Kaltenegger to Santa Monica for a conversation centered on one of science’s most enduring questions: Are we alone in the universe? The event, part of the organization’s Spark Salon series, took place on March 17 at 7:00 p.m. PT and was offered both in person and via livestream.
Kaltenegger, founding director of the Carl Sagan Institute at Cornell University and a professor of astronomy, is widely recognized for her work on habitable exoplanets and the search for detectable signs of life beyond Earth. Her talk focused not only on the science of planet hunting, but also on the assumptions people bring to questions about life, habitability, and reality itself.
According to the event announcement, the discussion examined how scientists interpret data from distant worlds and asked broader questions about what counts as life, what makes a planet habitable, and how human perspective can shape discovery. The program also highlighted how the search for life beyond Earth can challenge long-held ideas about what is normal, possible, and even alive.
The evening included a reception, the main program, and a book signing. In-person guests also received a complimentary copy of Kaltenegger’s book, Alien Earths: The New Science for Planet Hunting in the Cosmos.
Unlikely Collaborators, founded by Elizabeth R. Koch, describes itself as a nonprofit focused on helping people better understand themselves and the world through its Perception Box framework. The Spark Salon series regularly brings together researchers, artists, and thought leaders for conversations designed to challenge perspective and encourage reflection.

How extraterrestrial tales of aliens gain traction
The narrative explores humanity’s intrigue with extraterrestrial entities, juxtaposing evolutionary processes with claims of alien interventions, ultimately emphasizing the need for scientific evidence over fantastical stories. Aliens!
Last Updated on March 18, 2026 by Daily News Staff

One night, upon returning to the cave that his tribe calls home, the monkey-humanoid Moon-Watcher finds a strange crystal object, a kind of monolith that fascinates him at first, but then quickly loses his interest when he discovers that it is not edible. Soon after, the true purpose of the monolith is revealed to be none other than penetrating the minds of our ancestors to induce new abilities that, over time, will cause the development of an intelligence capable of creating new technology.
Many readers will recognise this scene from the novel 2001, A Space Odyssey, by Arthur C. Clarke, and the film of the same name, directed by Stanley Kubrick. It almost goes without saying that the crystal monolith in question is the work of an extraterrestrial civilisation that observes life on other planets and “experiments” on them to encourage the development of intelligence in as many parts of the cosmos as possible.
Seeking simple answers to complex questions
Understanding how we, as a species, came to be intelligent is one of the great enigmas of evolutionary study. Small mutations, followed by a process of natural selection to choose the most advantageous, seems too slow a process for structures as complex as the human nervous system or brain to emerge. It is this very complexity that allows millions of neurons to communicate with each other, resulting in the emergence of qualities such as the ability to respond voluntarily to environmental stimuli, or to ask questions about the very nature of humankind and the universe.
Nowadays, we know that there are evolutionary mechanisms that have lead to great leaps in terms of complexity, but that does not stop people from turning to non-human forces – Gods, extraterrestrials, spiritual energies – to explain things that are difficult to comprehend.
This has always been the case, in all human cultures. A classic example would be attributing atmospheric events – thunder, lightning, floods – to the wrath of God. These ideas came about before humans had ever left the ground, so it is no surprise that we turned our eyes even higher – to extraterrestrials – to explain other phenomena that we could only observe once travelling at high altitudes became part of our daily lives.
The allure of the unknown
The possibility that we might have been visited by beings from other worlds has always fascinated us. The element of mystery, of the unknown, only makes it more interesting.
Any phenomenon is made all the more enticing when it seems it is being covered up or hidden for secretive reasons. The attractiveness of conspiracies often leads people towards ideas which have no scientific basis, such as the belief that the Earth is flat, that humans never set foot on the Moon, or that vaccines can control our behaviour.
Even though these ideas have repeatedly been shown to be untrue, their rapid dissemination through social media, using simple, blunt language that appeals to emotion over logic, makes them very powerful weapons.
The supposed “proof” of alien visits to our planet ranges from specific Bible passages to ancient stone carvings portraying creatures or objects that may appear to be aliens or spacecraft. The latter often take the form of flying saucers.
However, we cannot forget that humans have always created imaginary creatures that resemble them and attributed them with magical powers. When imagining Gods, humans have given them a human appearance, and almost always imagined them as living in the sky.
When we look at these representations through modern eyes, we associate them with extraterrestrial beings or structures, when in fact they could be referring to a range of different things.
When unproven stories become larger than life
Recently, in the United States Congress, UFOs (currently known as UAPs: “Unidentified Anomalous Phenomena”) are back in the limelight. This is because a former air force intelligence official has made claims that the Pentagon is in possession of remains of extraterrestrial craft and “non-human biological matter”. The claims have been backed up by the testimony of a retired navy commander and a former navy pilot.
What we can be certain of is that the more we explore our skies, the more likely it is that we will encounter phenomena that we cannot explain. However, this does not mean that they are extraterrestrial. Past experience has shown us that most of these events can be attributed to optical illusions, spy or weather balloons, space junk, or even satellites that we ourselves have made.
In Spain, UFOs were a hot topic between the 1960s and the 1980s. In this era, everyone knew someone who was convinced that they had seen a UFO. This even reached the point where an exoplanet, called Ummo, was made up. It was populated by a more advanced civilisation than ours who made contact with people on Earth. In the letters these aliens supposedly sent, the ‘Ummites’ explained concepts such as genetics and cell structure.
The truth is that nowadays, reading some of these letters can be quite amusing. The story of the planet of Ummo was ultimately proved to be a monumental hoax, a fact later admitted by its own creator.
The Ummo hoax was even linked to the creation of a paedophile ring, which should make us reflect on the harmful consequences that the spread of fabricated news stories can have.
Can we deny the possibility that intelligent alien civilisations exist?
The answer, of course, is no. The universe is immense, and it is more than likely that circumstances similar to those which led to the appearance of life on Earth have been repeated on other planets. But there is a huge distance (literally and figuratively) between acknowledging the existence of these creatures and considering the possibility that they might have visited us.
Exoplanets, also known as extrasolar planets, are extremely far away, and we are limited by the speed of light which, as proven by Einstein, is the maximum possible speed at which anything can travel. Therefore, the journey to even a “nearby” exoplanet would take thousands of years. Maybe a civilisation more advanced than ours could find a way to do it faster, but not to the point of it being something easy or commonplace.
In any case, if the remains of alien life or spacecraft are stored away somewhere, why are they not being shown to us? Scientists would jump at the chance to analyse this organic matter to find out how it is structured, how it metabolises energy, or what molecules it uses to store genetic information.
Until there is proof, this is not a question of science, but rather, of stories. Stories can be very entertaining, but these kinds of stories do not help us to build a more accurate or helpful view of the world.

First contact with aliens could end in colonization and genocide if we don’t learn from history

First contact with aliens could end in colonization and genocide if we don’t learn from history

We’re only halfway through 2023, and it feels already like the year of alien contact.
In February, President Joe Biden gave orders to shoot down three unidentified aerial phenomena – NASA’s title for UFOs. Then, the alleged leaked footage from a Navy pilot of a UFO, and then news of a whistleblower’s report on a possible U.S. government cover-up about UFO research. Most recently, an independent analysis published in June suggests that UFOs might have been collected by a clandestine agency of the U.S. government.
If any actual evidence of extraterrestrial life emerges, whether from whistleblower testimony or an admission of a cover-up, humans would face a historic paradigm shift.
As members of an Indigenous studies working group who were asked to lend our disciplinary expertise to a workshop affiliated with the Berkeley SETI Research Center, we have studied centuries of culture contacts and their outcomes from around the globe. Our collaborative preparations for the workshop drew from transdisciplinary research in Australia, New Zealand, Africa and across the Americas.
In its final form, our group statement illustrated the need for diverse perspectives on the ethics of listening for alien life and a broadening of what defines “intelligence” and “life.” Based on our findings, we consider first contact less as an event and more as a long process that has already begun.
Who’s in charge of first contact
The question of who is “in charge” of preparing for contact with alien life immediately comes to mind. The communities – and their interpretive lenses – most likely to engage in any contact scenario would be military, corporate and scientific.
By giving Americans the legal right to profit from space tourism and planetary resource extraction, the Commercial Space Launch Competitiveness Act of 2015 could mean that corporations will be the first to find signs of extraterrestrial societies. Otherwise, while detecting unidentified aerial phenomena is usually a military matter, and NASA takes the lead on sending messages from Earth, most activities around extraterrestrial communications and evidence fall to a program called SETI, or the search for extraterrestrial intelligence.
SETI is a collection of scientists with a variety of research endeavors, including Breakthrough Listen, which listens for “technosignatures,” or markers, like pollutants, of a designed technology.
SETI investigators are virtually always STEM – science, technology, engineering and math – scholars. Few in the social science and humanities fields have been afforded opportunities to contribute to concepts of and preparations for contact.
In a promising act of disciplinary inclusion, the Berkeley SETI Research Center in 2018 invited working groups – including our Indigenous studies working group – from outside STEM fields to craft perspective papers for SETI scientists to consider.
Ethics of listening
Neither Breakthough Listen nor SETI’s site features a current statement of ethics beyond a commitment to transparency. Our working group was not the first to raise this issue. And while the SETI Institute and certain research centers have included ethics in their event programming, it seems relevant to ask who NASA and SETI answer to, and what ethical guidelines they’re following for a potential first contact scenario.
SETI’s Post-Detection Hub – another rare exception to SETI’s STEM-centrism – seems the most likely to develop a range of contact scenarios. The possible circumstances imagined include finding ET artifacts, detecting signals from thousands of light years away, dealing with linguistic incompatibility, finding microbial organisms in space or on other planets, and biological contamination of either their or our species. Whether the U.S. government or heads of military would heed these scenarios is another matter.
SETI-affiliated scholars tend to reassure critics that the intentions of those listening for technosignatures are benevolent, since “what harm could come from simply listening?” The chair emeritus of SETI Research, Jill Tarter, defended listening because any ET civilization would perceive our listening techniques as immature or elementary.
But our working group drew upon the history of colonial contacts to show the dangers of thinking that whole civilizations are comparatively advanced or intelligent. For example, when Christopher Columbus and other European explorers came to the Americas, those relationships were shaped by the preconceived notion that the “Indians” were less advanced due to their lack of writing. This led to decades of Indigenous servitude in the Americas.
The working group statement also suggested that the act of listening is itself already within a “phase of contact.” Like colonialism itself, contact might best be thought of as a series of events that starts with planning, rather than a singular event. Seen this way, isn’t listening potentially without permission just another form of surveillance? To listen intently but indiscriminately seemed to our working group like a type of eavesdropping.
It seems contradictory that we begin our relations with aliens by listening in without their permission while actively working to stop other countries from listening to certain U.S. communications. If humans are initially perceived as disrespectful or careless, ET contact could more likely lead to their colonization of us.
Histories of contact
Throughout histories of Western colonization, even in those few cases when contactees were intended to be protected, contact has led to brutal violence, pandemics, enslavement and genocide.
James Cook’s 1768 voyage on the HMS Endeavor was initiated by the Royal Society. This prestigious British academic society charged him with calculating the solar distance between the Earth and the Sun by measuring the visible movement of Venus across the Sun from Tahiti. The society strictly forbade him from any colonial engagements.
Though he achieved his scientific goals, Cook also received orders from the Crown to map and claim as much territory as possible on the return voyage. Cook’s actions put into motion wide-scale colonization and Indigenous dispossession across Oceania, including the violent conquests of Australia and New Zealand.
The Royal Society gave Cook a “prime directive” of doing no harm and to only conduct research that would broadly benefit humanity. However, explorers are rarely independent from their funders, and their explorations reflect the political contexts of their time.
As scholars attuned to both research ethics and histories of colonialism, we wrote about Cook in our working group statement to showcase why SETI might want to explicitly disentangle their intentions from those of corporations, the military and the government.
Although separated by vast time and space, both Cook’s voyage and SETI share key qualities, including their appeal to celestial science in the service of all humanity. They also share a mismatch between their ethical protocols and the likely long-term impacts of their success. https://www.youtube.com/embed/5gZwLGrJQrM?wmode=transparent&start=0 This BBC video describes the modern ramifications of Captain James Cook’s colonial legacy in New Zealand.
The initial domino of a public ET message, or recovered bodies or ships, could initiate cascading events, including military actions, corporate resource mining and perhaps even geopolitical reorganizing. The history of imperialism and colonialism on Earth illustrates that not everyone benefits from colonization. No one can know for sure how engagement with extraterrestrials would go, though it’s better to consider cautionary tales from Earth’s own history sooner rather than later.
This article has been updated to correct the date of James Cook’s voyage.
