12 Best Educational YouTube Channels in 2026 (+ How Often They Post)

The best educational YouTube channels make hard subjects like physics, math and history fun to learn. The catch is that many of them post only every few weeks or months, and YouTube often doesn't tell you when they do.

How we picked

Every pick is free, teaches a real subject and posted a long-form video in 2025 or 2026. Gaps are the median time between each channel's last 15 long-form videos (Shorts left out), read from its public YouTube uploads feed on October 25, 2026.

Best science YouTube channels

1. Veritasium

Veritasium, founded by Derek Muller, is the best all-round science channel on YouTube. Each video is built around an experiment or a surprising question, like October 2026's test of our theory of gravity. Expect a long-form video about every 10 days, plus Shorts. Get Veritasium uploads by email.

2. Kurzgesagt

Kurzgesagt turns science into bright, calm animation, made by what its channel calls a team of "illustrators, animators, number crunchers and one dog." Long-form videos arrive about every two weeks, though one 2026 gap ran 52 days. Get Kurzgesagt uploads by email.

3. SmarterEveryDay

SmarterEveryDay follows Destin Sandlin as he explores the world using science. Episode 317 went inside a nuclear reactor core in September 2026. New episodes land about every eight weeks, which makes it one of the easiest channels to miss. Get SmarterEveryDay uploads by email.

4. PBS Space Time

PBS Space Time is the deep end of physics on YouTube. Astrophysicist Matt O'Dowd hosts episodes on black holes, quantum mechanics and empty space, about one every two weeks. Follow PBS Space Time by email.

Great educational channels that upload rarely

Some of the best educational channels on YouTube post a long-form video only a few times a year. These five post no Shorts in between, so a long gap means total silence. Dates come from our October 25, 2026 check of their public uploads feeds.

Channel	Subject	Latest long-form video	Longest gap in its last 15 videos
OverSimplified	History	Jan 18, 2025	503 days
CGP Grey	Explainers	Apr 14, 2025	311 days
Historia Civilis	Roman and 19th-century history	Apr 18, 2026	279 days
Mathologer	Math	Apr 11, 2026	182 days
SmarterEveryDay	Science	Sep 26, 2026	69 days

Vsauce shows the same pattern with a twist. It posts Shorts often, but its July 2025 long-form video, "All The Ghosts You Will Be," came more than two and a half years after the one before it. When channels like these do post, it is usually a big video fans have waited months for.

Why it's easy to miss a new video from a slow channel

YouTube's bell works worst for the channels that post least often. Three things work against a slow educational channel:

The bell starts on Personalized. YouTube Help says new subscribers "automatically get personalized notifications," which cover only "some uploads, Shorts, and live streams" (YouTube Help).
All has an inactivity rule. Since YouTube made it permanent in April 2026, All-bell subscribers who haven't watched a channel for about a month, and haven't engaged with its recent alerts, get its notifications only in the app's inbox (PPC Land).
Your Home feed leans on recent viewing. A channel you haven't watched in weeks shows up less, as our guide to why your Home feed ignores subscribed channels explains.

SmarterEveryDay posts about every eight weeks, and OverSimplified went a year between parts. A fan who only watches their main videos goes well over a month without watching, which is exactly when the push alert stops. Our explainer on YouTube's 2026 bell change has the details.

How to follow educational YouTube channels without missing an upload

The reliable setup is the bell plus an email alert for the channels you care about most. It takes about a minute per channel.

Subscribe and set the bell to All. Our guide on how to subscribe to a YouTube channel covers every device.
Add an email alert. Search the channel on Sublark by name or @handle and enter your email address. Sublark emails you after each new public upload, usually within the hour. It is free for viewers and needs no app or Google account.
Keep it in one inbox. See how to track multiple YouTube channels in one inbox.
Learn each channel's rhythm. Our guide to when a YouTube channel uploads shows how to spot a schedule like Practical Engineering's Tuesdays.

Sublark checks each channel's public uploads feed, not your viewing habits, so a long gap makes no difference. It emails every new public upload, Shorts included.

Frequently Asked Questions

What is the best educational channel on YouTube?

There is no single winner, but Veritasium is the strongest all-round pick for curious adults and teens. It covers physics, engineering and the history of science through experiments and stories, and it posts a long-form video about every 10 days. For math, 3Blue1Brown is the standout. For full school-style courses, CrashCourse has made more than 60. Kurzgesagt is the best animated science channel. Pick two or three that match what you want to learn, and follow them by email so new videos do not slip past.

What are the best educational YouTube channels for adults?

Adults get the most from channels that go deep instead of fast. Veritasium, PBS Space Time and 3Blue1Brown treat viewers as smart beginners. Practical Engineering explains the infrastructure around you, and Wendover Productions explains how travel, shipping and economies work. For history, OverSimplified is the funny option and Historia Civilis is the detailed one. Most of these post every one to eight weeks, so an email alert is the simplest way to hear about each new video without checking YouTube.

What are the best science YouTube channels?

Veritasium, Kurzgesagt, SmarterEveryDay and PBS Space Time are the four best science YouTube channels in 2026. Veritasium mixes physics and engineering with real experiments. Kurzgesagt explains space, biology and the future in short animations. SmarterEveryDay follows Destin Sandlin as he investigates how things work, about every eight weeks. PBS Space Time, hosted by astrophysicist Matt O'Dowd, goes deepest on black holes and quantum physics, with a new episode every two weeks. For hands-on chemistry, add NileRed.

What are good educational YouTube channels for kids?

This list is aimed at teens and adults, though Mark Rober, Kurzgesagt and TED-Ed work well for families. For younger children, Crash Course Kids covers science and literature at an elementary level. One catch: YouTube Help says you won't get notifications from a channel whose audience is set as made for kids, and you can't change that bell. Sublark does not use the bell. It checks each channel's public uploads feed, so you can still get an email when a new public video goes up.

How do I get notified when an educational channel uploads?

Subscribe and set the bell to All, then add an email alert for the channels you care about most. The bell starts on Personalized, which covers only some uploads, and YouTube can stop pushing All alerts if you have not watched a channel for about a month. That hits slow channels hardest. Sublark emails you after each new upload, usually within the hour, needs only your email address, and is free for viewers.

Why do some educational YouTube channels upload so rarely?

Good educational videos take a long time to make. Research, scripting, animation and filming can take months for a single topic, and many of these creators work alone or in small teams. In our October 25, 2026 check, OverSimplified's latest video dated from January 18, 2025, and Historia Civilis and Mathologer had each posted one long-form video in the past year. A slow schedule is normal for this kind of channel, so fans rely on alerts instead of checking every day.
