Watch This Space: 10 Must-See Documentaries About the Universe

Dan Price Updated 14-08-2019

The universe is impossibly large, and humans are still confined to a tiny corner of it. However, we’re constantly learning more about the universe and our place in it. And these space documentaries will help you explore the universe from the comfort of your own living room.


1. IMAX: Hubble

IMAX: Hubble IMAX: Hubble Buy Now On Amazon $5.99

The Hubble Space Telescope is one of the most important objects that we’ve ever put into orbit around the Earth. It has fundamentally changed our understanding of space, making important discoveries about black holes, the expansion of the universe, and the age of the cosmos.

Multiple missions have upgraded, repaired, and replaced systems on the telescope. The IMAX: Hubble documentary—narrated by Leonardo DiCaprio—looks at these missions in more detail, As you might expect, this space documentary is packed with awe-inspiring footage.

2. Into the Universe with Stephen Hawking

British scientist Stephen Hawking may not be with us any longer, but he has cemented his position as one of the greatest astrophysicists to have ever lived. Who better, therefore, to try and explain the mysteries of the universe in a way that’s understandable to everyone?


This three-part documentary—which was first aired in 2010—looks at aliens, time travel, and the story of the universe. It is one of the best shows about space you can watch, whether or not you’re a fan of Hawking. As a bonus, Benedict Cumberbatch helps with narration.

3. The Farthest: Voyager in Space

Another space documentary worth watching is The Farthest: Voyager in Space.

NASA launched Voyager 1 in September 1977. After spending much of the last 40 years traveling at an incredible 40,000 miles per hour, it is now 13.6 billion miles away from Earth. As such, it is comfortably the most distant man-made object from Earth.


As the mission slowly starts to wind down (the craft’s power supply will die in 2025), The Farthest: Voyager in Space looks back at the people and events behind one of our greatest collective achievements.

4. Apollo 11

Apollo 11 is another of the best documentaries about space. It’s also one of the newest documentary films on our list; it was first shown in theaters in early 2019.

The film, which grossed $11 million at the box office, has no narration, interviews, CGI, or other effects. It’s just 90 minutes of incredible archival footage from the successful moon landing of the Apollo 11 mission. Much of the footage had never been previously seen by the public.


If you want further evidence of how good this space documentary is, look no further than the notoriously harsh Rotten Tomatoes website. The film currently has a 99 percent score from critics.

5. How the Universe Works

How the Universe Works is one of the best shows about space.

First produced by the Discovery Channel in 2010, and narrated by Mike Rowe and Erik Todd Dellums, it’s a docu-series rather than a film. There are currently seven series and counting.


The first series’ episodes had simple titles like “Black Hole” and “Stars.” By the seventh series, the content had developed into explaining more complex theories.

6. Out of the Blue

Many people love watching documentaries on the subject of aliens. However, 2002’s Out of the Blue is considered to be one of the most comprehensive films about the possibility of life on other planets.

It features interviews with the scientific community, alleged eyewitnesses, high-ranking military personnel, and senior government officials. They all discuss the possibility that some Unidentified Flying Objects (UFOs) could have come from other planets.

7. The Last Man on the Moon

The Last Man on the Moon The Last Man on the Moon Buy Now On Amazon $7.99

Everyone knows that Neil Armstrong was the first man to walk on the moon. The name of the last man, however, is less well-known. That person is Gene Cernan. He was the last astronaut to get back inside the Lunar Module after the Apollo 17 mission in 1972.

The Last Man on the Moon looks at the career of Cernan, along with the other 10 astronauts who stepped onto the lunar surface after Apollo 11 but whose names the public has largely forgotten.

8. Cosmos: A Space-Time Odyssey

Cosmos: A Space-Time Odyssey Cosmos: A Space-Time Odyssey Buy Now On Amazon $27.29

Cosmos: A Space-Time Odyssey is another brilliant show about space. Presented by world-famous astrophysicist Neil deGrasse Tyson, the 13-episode series is written as a follow-up to Carl Sagan’s 1980 masterpiece, Cosmos: A Personal Voyage.

The new production was a critical success. It won 12 Emmy Awards in 2015, including “Outstanding Documentary or Nonfiction Series” and “Outstanding Writing for Nonfiction Programming”. It also picked up the Peabody for excellence in documentary filmmaking.

Episodes cover everything from the start of life on Earth to the wave theory of light.

9. Galileo

Galileo Galileo Buy Now On Amazon

While there are some brilliant astronomy documentaries out there, we have chosen something a little different for our list. Galileo is a biographical film about Galileo first released in 1975. It’s an adaptation of Bertolt Brecht’s play of the same name.

Galileo Galilei was a 17th-century Italian scientist. He is known as the father of observational astronomy, and was a proponent of Copernican heliocentrism. These beliefs landed him in trouble with the Catholic Church and led to many years spent under house arrest.

10. Wonders of the Solar System

The final entry in our list of the best space documentaries is Wonders of the Solar System. It’s a 2010 BBC production which Professor Brian Cox hosts and narrates.

In total, the space show comprises of five standalone episodes. They look at the behavior of the sun, the orbit of the planets, the atmosphere of the planets, the history of Mars, and aliens.

Like Cosmos: A Space-Time Odyssey, Wonders of the Solar System won a Peabody Award for excellence in documentary filmmaking.

    How the Universe Works. I really enjoyed the episodes the Big Bang, Galaxies, Supermassive Black Holes, and especially the episode Stars as it shows size scales of other stars dwarfing our own.

    National geographics series 'how the universe works' is probably the best that i have seen. Some documentaries mentioned in this list are somewhat unscientific and speculative projecting the values and opinions of the makers onto the wiever.

    Billions of stars and millions of planets? Lets try trillions of stars and billions of planets. Nearly every star you see (and don't see) has at least one planet that orbits its host. The vastness of those numbers are incomprehensible to a lot of people. To put the vastness of space in perspective if you was to take a ride on ship that travels at the speed of light across our galaxy it would take the person 100,000 years to reach from one side to the other. That is just OUR galaxy. There are literally BILLIONS of galaxies out there! I don't like it when people diminish the vastness of space. It irks me. Lol

      Thanks for your comment. And I agree, the vastness of space is truly astounding! Even trillions of stars and billions of planets may not do justice to the vast number of objects in space. Btw, which doc was your favorite or which favorite doc of yours was left of the list? I wouldn’t mind watching a space video series I haven’t seen before.
