Science Video Library: The Best Explainers, Organized by Topic

Updated June 2026 Curated by topic
There is a huge amount of brilliant science on YouTube, and an enormous amount of noise around it. This library is our answer: a hand-picked set of the clearest, most accurate science videos we have found, grouped by subject and paired with our own in-depth written guides. We did not make these videos, we curated them, and every one comes with context on what it covers and why it earned a place here. Pick a topic below to start watching.

The Creators We Feature

We lean on a small group of science communicators whose work is both accurate and genuinely well made. Each video credits its creator and links back to their channel, where you will find far more than we could ever feature here.

Astrum

Alex McColgan's space documentaries, built from real probe and telescope imagery of the solar system and beyond.

Veritasium

Derek Muller's physics and engineering films, full of real demonstrations and the kind of question that overturns what you thought you knew.

World Science Festival

Long-form conversations and lectures hosted by physicist Brian Greene with many of the leading scientists working today.

Arvin Ash

Tight, intuition-first explainers that take on the hardest topics in physics in about fifteen minutes, with no clickbait.
