The Top 11 YouTube Channels to Help You Learn About Space in 2025

Everyone has looked up at the stars at some point and wondered what lies beyond. In the digital age, using online platforms like YouTube to satisfy that curiosity has become second nature. While space content is everywhere, not all of it is reliable or educational. That’s why we compiled a list of unbiased YouTube channels, so you can inform yourself with accurate and engaging space science.

Understanding our universe is the cornerstone of appreciating the vastness of existence, and these channels help make that possible. If you're fascinated by black holes, space missions, or time travel theories, these channels should be your go-to source. The list includes creators who are scientists, educators, engineers, and passionate communicators.

We're sure you'll find a channel that fits you perfectly, whether you're a beginner or an aspiring astrophysicist. In this article, let's delve into the top 11 YouTube channels that cover astronomy, space exploration, and astrophysics with clarity, credibility, and creativity.

1. Fraser Cain

His YouTube channel lets you learn about galaxies, black holes, dark matter, and space telescopes from a science-based perspective. Fraser Cain was the creator of Universe Today, a well-known space news website. I loved how easy and fast it was to find information about current space missions and telescope discoveries.

It also covers topics like the future of Mars exploration, telescope launches, and the search for alien life. Videos can also include interviews with astrophysicists, planetary scientists, and engineers. These are friendly discussions, so it might be useful for those new to astronomy.

You can choose episodes focused solely on specific missions or theoretical space science. There are many playlists organized by topic, making it simple to locate content on common space subjects.

2. Anton Petrov

With a calm and steady tone, Anton summarizes space research findings, often including visual simulations and references to original scientific sources. His content is tailored for science enthusiasts who can benefit from consistent exposure to astronomy developments.

As someone who enjoys keeping up with the latest in space exploration, you can use this channel as a daily touchpoint for emerging knowledge. Once you get familiar with his style, Anton Petrov lets you follow research trends efficiently, which you can apply to personal studies or general curiosity.

Since I’m all about improving scientific literacy, I’ve noted how the channel regularly uses simulations, together with real data, to illustrate points, demonstrating its potential for a highly visual and informed learning experience.

3. Astrum

As you scroll through the channel, noticing the wide variety of topics that focus on space, you may get interested in the inner workings of our neighboring planets first.

Their animations and explanations are specially designed to provide a closer look at surfaces, atmospheres, and mysteries far beyond Earth.

This is definitely one of the most popular YouTube channels when it comes to visually rich astronomy content! With over a million subscribers and a consistent upload schedule, you’ll be able to get access to a variety of topics that cover both new discoveries and historic space events.

Also, with the high-quality rendering and calm narration, you can get a better sense of what it's like to observe space from a scientific lens. It helps to watch a few videos in a row if you're trying to get familiar with different planetary systems or unusual space events.

4. Joe Scott

We also prefer such casual yet informative approaches, and it helped us absorb information without feeling overwhelmed. The rest you get is a blend of curious questions and detailed explanations. Unlike some purely academic channels, you can try to follow along even without a scientific background. One of the biggest benefits is how the content feels accessible.

There are videos that cover not only current space exploration but also the broader questions about humanity’s place in the cosmos. With its straightforward style and clear examples, it empowers viewers to think about space topics without needing prior expertise.

5. Isaac Arthur

It is similar to science documentary channels because it allows people to consider complex ideas about humanity’s future in the cosmos.

Isaac Arthur is one of the most detailed channels on speculative space science, with thorough research and carefully structured presentations, whether they are beginners, science enthusiasts, or professionals interested in theoretical astrophysics.

Isaac Arthur is a specialized educational channel, especially as a source for futuristic space scenarios. Currently, there are hundreds of episodes available.

However, unlike more general astronomy channels, it places more attention on speculative and long-term possibilities rather than current space exploration events. Because of this, you may find the content more theoretical than practical.

6. Everyday Astronaut

The channel often breaks down how rockets work, what goes into a launch, and how private companies are shaping space travel—and so much more. It also presents technical walkthroughs of launch pads and rocket engines. Some of them are interviews with engineers. Along with these technical explanations, you can watch full-length coverage of real-time missions.

There are several recurring series, and to understand them fully requires some familiarity with orbital mechanics. 

7. Launch Pad Astronomy

It also includes livestreams of major missions and space updates. This is definitely a good place to start.

Astronomy discussions often include visuals and slides, which makes it easier to follow for learners at any level. See what other space-curious viewers are saying in the comments—this channel encourages open discussion.

You’ll come across topics like stellar evolution, black hole formation, and exoplanet detection, just to name a few. It combines lecture-style narration with practical illustrations to help explain recent headlines and classic astronomical concepts.

8. Real Engineering

Since its launch, the channel has featured content that enables learners to see the connections between scientific theory and real-world space applications. With Real Engineering, you don’t just watch animations, but you observe how detailed models explain fuel efficiency, propulsion systems, and orbital mechanics.

There is occasional coverage of general engineering, but there are numerous videos centered specifically on space-related projects—such as reusable rockets or satellite deployment systems. These videos are informative, as they often include timelines, technical data, and comparisons with past missions.

The channel provides diagrams, breakdowns, and real-world examples which enable users to analyze how different parts of a space mission function together in a logical, methodical way. For example, one video breaks down the structure and purpose of heat shields in a precise, measured way.

9. Scott Manley

Scott Manley isn’t your average commentary channel so much as it is a way for you to understand real-time developments in aerospace and astrophysics. Rather than walk you through general summaries, Scott Manley presents you with detailed explanations of how things actually work in spaceflight. With years of experience in physics and astronomy communities, this channel provides accurate insights backed by simulation and analysis.

10. Dr. Becky

Once you get used to her weekly updates, you have to pay attention to how she connects news headlines to scientific research. Her tone remains steady, and her content leans toward the academic side, though always accessible.

It also has some of the most frequently updated summaries of space missions and telescope discoveries. It have consistent uploads, whether she’s reviewing JWST images or discussing neutron stars.

If you don't follow her explanation of a recent paper, you have to rewind and watch carefully—she doesn’t oversimplify. I didn't consider how detailed galaxy rotation curves could be, which often requires multiple replays to absorb fully.

11. PBS Space Time

While many science channels focus on space facts and updates, PBS Space Time goes far deeper into the “why” behind the universe. I find this to be extra helpful, especially when trying to wrap my head around the complex interplay between physics and cosmology.
