Where did our unique moon come from? It turns out that lunar rocks brought back by Apollo astronauts are a clue, pointing to the origin of our closest cosmic companion, an origin even stranger than you might imagine

The oldest rocks on Earth are more than just ancient—they’re time machines, holding clues to Earth’s missing history and revealing what happened in the unknown times after the Big Bang. We’ll work with our Adam and Joss from Howtown to...

The Appalachian Mountains are some of the oldest geological features on earth. And they also hold fossils that tell us about some of the very earliest life forms that we'll ever manage to see in the fossil record. So how did these...

An asteroid nearly twice the size of the one that killed the dinosaurs left a record-setting crater in South Africa. If you look closely, you can still see it today, 2 billion years later. Hosted by: Jaida Elcock (She/her)

There's a rare material called Darwin Glass that Tasmanian Aboriginals have prized for centuries. And while it took Western researchers a while to figure out what it was and where it came from, once they got their heads around it, they...

Did the Easter Islanders really cause their own civilization's collapse? Probably not. In fact, they used rock gardens to grow food sustainably on the island of Rapa Nui for centuries. Hosted by: Savannah Geary (they/them)

In the past decade, astronomers have discovered interstellar objects, including a 2014 meteor that collided with Earth and 'Oumuamua in 2017. These objects, moving too fast to be bound by the Sun's gravity, have sparked questions about...

January babies, rejoice! This month's SciShow Rocks Box video is the story of garnets, and how these fabulous gemstones help us solve geological mysteries, from the Italian Alps to the Himalayas.

This month, our SciShow Rocks Box subscribers are getting a really special treat -- a real, living, pet rock! These critters have been beloved companions for decades, and we're bringing you pet rocks from the original wild vein, meaning...

So, rocks are hard. But the scale we use to rank them, the Mohs scale, is only really good at quantifying that for one kind of hardness, and topaz is a perfect stone to talk about to explain that. And you can check it out in our SciShow...

Epidote might just look like a pretty little crystal, but it has a secret. thanks to the high-pressure circumstances where it forms, we can use it to help us uncover the origins of life on our planet, and maybe even find signs of life on...

I was in Arizona recently for Phoenix Comic-Con, and had the amazing pleasure of seeing one of Earth's greatest natural wonders… the Grand Canyon. More than a mile deep, and several miles across, it just defies belief. But I couldn't...

From an Australian fire that's been continually burning for millennia, to earthquakes that shake the ground for centuries, here are four natural disasters that lasted way longer than you might have expected.

It's always an asteroid heading straight toward us that we worry about, never what happens to us when we head straight toward the asteroid. OSIRIS-REx's experience with Bennu tells us it's worth a thought.

Is it possible that life on earth began with an out of this world rock buffet?

Earth didn't always have the land beneath your feet, but what might have caused it to form is a bit of a mystery.

Mountain ranges usually don't form in the middle of continents. Except for the Rocky Mountains. We'll go into the baffling Laramide Orogeny and a few possible reasons why the Rockies might be in the wrong place.

For decades, researchers thought they had a solid idea about the earliest booms in animal life. But new research might have turned off the gas on all these ideas, flipping our understanding of the Avalon explosion and the Cambrian...

In astronomy we talk about billions of years like it’s no big deal. But how can we be sure about timescales so far beyond the capacity for human intuition? Our discovery of what we now call deep time is very recent - as recent as our...

With the global pandemic of Covid 19 still encompassing the world, we are generally not big fans of viruses right now. But we sure are thinking about them a lot. That’s right, even astrophysicists are pondering these bizarre little...
