The best documentary series about space and astronomy
The night sky has always pulled on human curiosity, and few formats capture that pull more powerfully than a well-made documentary series. Across decades, broadcasters have returned to the same fundamental subjects — the birth of stars, the slow death of galaxies, the quiet probability that we are not alone — refining visual storytelling each time. Streaming platforms now archive entire seasons of space science in 4K, ready to queue up on a lazy weekend.
Australia's viewing culture has quietly deepened alongside this global surge. On a Saturday night in Adelaide or after work in Parramatta, more people are firing up documentaries that walk them through the cosmos. ABC iview, SBS On Demand and Foxtel all carry legacy BBC and Discovery series, and the recent boom of originals on Netflix, Disney+ and Apple TV+ has widened the catalogue. The home-viewing habit also rewards storylines that suit slow sessions and crisp panels, both of which space documentaries deliver.
With so many options now competing for screen time, the challenge for Australian viewers is no longer a lack of content but a question of taste. Are you after a sweeping, philosophically charged tour of the universe, a hard-science look at black hole formation, or a planet-by-planetary walk through our own neighbourhood? The series below cover all of those modes, each with its own visual signature, pacing and approach.
Cosmos and its successors
Carl Sagan's Cosmos: A Personal Voyage arrived in 1980 and immediately changed the genre, wrapping frontier astrophysics in metaphor and poetry. Its influence echoes through every cosmic docuseries since, including its 2014 successor Cosmos: A Spacetime Odyssey, hosted by Neil deGrasse Tyson. Tyson does not imitate Sagan; he leans into a more kinetic visual style, deploying ship-of-the-imagination sequences that anchor abstract ideas in concrete imagery. The thirteen episodes treat everything from gravitational waves to the deep chemistry of life as a single connected story, a structure that has become the template other mainstream space docs either adopt or push against.
A decade later, Cosmos: Possible Worlds (2020) extended the project further with its eye on real laboratories and the speculative engineering of tomorrow. Scenes from the Atacama and the labs of Marseille sit beside sequences that imagine solar sails and genetically restored ecosystems. For Australian audiences, episodes featuring radio antenna dishes and high-altitude telescopes feel especially tangible, since they mirror work done at Tidbinbilla and other tracking facilities. Watching the trilogy together produces an unusual effect — a patient build of how science and wonder feed each other.
Touring the solar system
The BBC's The Planets (2019), presented by Brian Cox, narrowed the scope to five episodes and one perfect topic: our own star, the eight worlds that orbit it, and the Soviet-era missions that started the data set. Cox's trademark is frictionless exposition, the kind that walks a viewer through magnetospheres without losing their attention. The series leans heavily on NASA's Mariner, Voyager and Cassini archives, splicing archival footage with new visualisations of Jupiter's storms and Titan's methane lakes.
| Series | Year | Episodes | Focus | Style |
|---|---|---|---|---|
| The Planets | 2019 | 5 | Solar system tour | Narrative docuseries |
| Cosmos: A Spacetime Odyssey | 2014 | 13 | Cosmic history | Visual essay |
| Our Universe | 2023 | 6 | Solar system + beyond | Hybrid docu-drama |
| Mars | 2016 | 6 | Mars colonisation | Docu-drama |
| How the Universe Works | 2010–present | 60+ | Astrophysics anthology | Anthology |
Our Universe (2023, Netflix) took a softer, lifestyle-friendly route, swapping cosmic awe for sweeping cinematography of planetary motion. For viewers in Sydney or Perth who prefer a slower pace, it pairs nicely with a long evening. Across both series, the storytelling leans on the momentum of older 1970s missions, repurposing that archive for a generation raised on streaming video and tighter episode runs.
Mars up close
Mars carries its own special gravity in space documentaries, partly because every decade brings a new rover and a new promise of crewed landing. National Geographic's Mars (2016) mashed two formats together: scripted future-crew drama intercut with interviews from real engineers at JPL. The result sits closer in feel to the lineage of modern superhero films than to classical nature documentaries — partly a six-hour recruiting video for the science teams, partly a fully produced series that looks like a feature film broken into chapters. Watching it after the Ingenuity helicopter's flights adds a layer of present-day relevance older Mars documentaries cannot match.
From Inside SpaceX (2020, Netflix) to the more meditative Mars Diaries archive shows hosted on YouTube, the planet has carved out its own shelf in the documentary library. The Australian Space Agency, headquartered in Adelaide, has begun funding educational projects that speak to the country's role in future Mars missions, particularly through student-built cubesats and the local robotics scene at the University of South Australia. These newer additions share a stronger focus on collaboration between industry and research, a tone that suits our country's growing scientific identity in Adelaide and beyond.
Inside black holes and galaxies
When viewers are ready for harder cosmology, the longest-running option is also the easiest to find. How the Universe Works, produced by Science Channel since 2010 and now past its tenth season, treats the field as an anthology. Each episode is a focused case study on a specific phenomenon. Black holes, dark matter, supernovae and rogue planets each receive their own hour, with rotating hosts and academic consultants in support. The format rewards dipping into single episodes rather than committing to a full season, an approach that suits a busy weeknight schedule.
Closer-to-current-cinema options include the Stephen Hawking–narrated Into the Universe (2010), the PBS Nova special Black Hole Apocalypse (2018), and the documentary Black Holes: The Edge of All We Know (2020). Australian researchers connect to several of these projects, particularly through CSIRO's radio telescope work at the Murchison Widefield Array in Western Australia and contributions to the Event Horizon Telescope collaboration. The 2019 black hole image, the first of its kind, was partly captured using data from Australian-linked facilities, a fact that has shown up in newer episodes of the genre with surprising speed.
Indigenous skies and Australian observatories
Outside the Hollywood production pipeline, Australian creators have produced their own space documentary content. SBS released its short series Eight Days at the Edge of the Universe, and there have been several local profiles of the Australian Space Discovery Centre in Adelaide. The continent's long history of scientific astronomy now sits beside a much older tradition: Indigenous Australian astronomy, which treats the Southern Cross, the Emu in the Sky and the dark constellations as a sophisticated map of seasonal behaviour. Documentaries like Star Stories of the Dreaming and shorter educational pieces from the ABC have begun bringing this older knowledge into the modern viewing experience.
Australia's space infrastructure remains a quiet success story. The dish at Tidbinbilla Deep Space Communication Complex outside Canberra still tracks missions from across the solar system, while the Square Kilometre Array — to be built at Boolardy in the Murchison region of Western Australia — promises to be the world's largest radio telescope once operational. The same radio-quiet landscapes have given rise to thoughtful climate and nature films on streaming platforms, many of which use the same Australian countryside as their setting and soundtrack.
The James Webb era
The most exciting recent shift in the genre is the visibility of JWST imagery in documentary form. Series like PBS's Nova, the BBC's Horizon and newer Netflix originals have all assembled special episodes around specific JWST campaigns, the kind of fast-turnaround filmmaking that used to belong to news desks. For viewers who only catch headlines, these short specials function as the bridge between social-media imagery and a fuller explanation. Australian contributions to data pipelines mean that some of these specials refer to locally collected calibration sets, a small but meaningful reminder that space research is a global project with local fingerprints.
Beyond JWST, the next generation of documentaries will likely focus heavily on Artemis, lunar Gateway construction and the prospect of off-Earth manufacturing. Documentaries in production now lean on the same streaming-first architecture that powered earlier docuseries on climate and pandemic science, treating each topic with a four-to-six-episode arc rather than a single two-hour film. For viewers in Melbourne, Brisbane or Hobart, this format is more approachable than marathon-length features, particularly during the working week.
Watch at home and explore further
For Australian viewers choosing where to start, the safest bet is to follow the platforms you already pay for. BBC Studios content tends to live on Apple TV+, while National Geographic programming sits on Disney+. The long tail of older catalogue titles, including the original 1980s Cosmos, surfaces periodically on Stan and SBS On Demand. Setting subtitles while streaming remains one of the most underrated habits of careful viewing, especially when a series tosses around technical terms like proto-planetary disc or infall velocity. With a clear caption line at the bottom of the screen, every episode becomes easier to enjoy on first watch.
Space is not the only subject worth queuing up either. Pair a slow-burning cosmic docuseries with one of the broader documentary styles on the platform and the evening can run from cosmology to climate science without breaking stride. Block a few hours in Brisbane or Adelaide, dim the lounge room lights, and the next chapter of the universe will be waiting on your screen.
