Wood is abundant and full of energy, but outside of some insects, almost no animals eat it because the stuff it's made of is hard to break down

Stefan and Alexis are headed to Olympic National Park in Washington state to bring you some of the coolest geology stories there. This week, they explore why Mount Olympus should be taller than Mount Everest.

Today Emily Graslie of The Brain Scoop gives us the news about a couple of near- misses for our planet and an update on where astronomers think habitable life might be found in other star systems.

It turns out the name Boaty McBoatface didn't go to waste, and the submersible now bearing the name has returned from its first mission! Also, the diversity of frogs we see today may have arisen more recently than we previously thought!

What would you do if you were in charge of a billion-dollar satellite that was spinning out of control? In 1998, NASA and ESA engineers had to solve this exact problem. How did they avert this disaster?

Despite computers barely being a thing when she was born, Valerie Thomas knew that she was cut out for the tech world, pushed until she got there, and contributed to some hugely important technologies that many of us could not live without.

In 1991 a single atomic nucleus slammed into our atmosphere with the intensity of a macroscopic object. It's been named The Oh-My-God particle.

We here at SciShow like to start things off with a "Boom" for yet another season! Hank talks about the mystery behind the "Space Roar" and why it is we can't really hear it.

Why You Should Care About Nukes

It's leap year time... so what are years, anyway? And what do they have to do with the supermassive black hole in the core of the milky way?

What can an equation tell us about whether or not we're alone in the universe?

For ages I’ve been thinking about doing a video analyzing time travel in fiction and doing a comparison of different fictional time travels – some do use wormholes, some relativistic/faster than light travel with time dilation, some...

Hank introduces us to ecology - the study of the rules of engagement for all of us earthlings - which seeks to explain why the world looks and acts the way it does. The world is crammed with things, both animate and not, that have been...

Jedidah Isler first fell in love with the night sky as a little girl. Now she's an astrophysicist who studies supermassive hyperactive black holes. In a charming talk, she takes us trillions of kilometers from Earth to introduce us to...

Albert Einstein strongly disagreed with Niels Bohr when it came to Bohr's interpretation of quantum mechanics. Quantum entanglement settled the argument once and for all.

Tiny remnants of extreme nuclear reactions in space are flying through your body right now. And astronomers are hunting them to learn more about some of the most energetic and violent objects in the universe.

Nothing's final yet, but there might be a drone, called the Mars Helicopter, on the upcoming Mars 2020 rover.

This week on SciShow Space News, researchers have figured out which gas drives fire fountain eruptions on the Moon. And you can send a message or your name to the Moon or Mars!

Astronauts ate some space-grown lettuce, and astronomers discovered a ring of galaxies that's so big it defies the laws of physics.

SciShow News serves up the latest pictures from Comet 67-P, that media darling, and the discovery of what may be the oldest, rocky Earth-like worlds yet found.

Michael Collins isn't as recognizable a name as Buzz Aldrin and Neil Armstrong, but his job on the Apollo 11 mission was just as important.

SciShow Space preps you for the Delta Aquarids, a meteor shower, and explains what makes them so unique. Plus, join "aquanauts" on one of NASA's least-known missions, a nine-day tour in its NEEMO undersea laboratory.

This week in space. Scientists have discovered a black hole that could possibly everything we know about black holes, and also, evidence that planets, yes planets, could form around super massive black holes.

Two scientists have proposed that Planet Nine could actually be a black hole, and a handful of telescopes observed a distant black hole absolutely destroying a star!
