The Mystifying Structures Hidden Within Earth’s Mantle
Over four decades have passed since researchers discovered two continent-sized blobs wrapped around Earth’s core, and they’re still trying to figure out what they are. Here’s what they know so far. There’s a Subterranean Biosphere Hiding in the Earth’s Crust and It’s MASSIVE – Read More: The Unsolved Mystery of the Earth Blobs “Part of […]
Origins of the Earth’s magnetic field
If you’re alive and reading this, you can thank the Earth’s magnetic field, which provides a protective barrier against the sun’s harmful radiation. But how did our magnetic field begin? New research from the College of Earth, Ocean, and Atmospheric Sciences at Oregon State University suggests that an ancient magma ocean deep inside the Earth’s […]
What's Actually Inside the Earth's Core? | Journey to the Center of the Earth
Have you ever wondered how we *really* know what’s at the center of the Earth? Thanks to some amazing scientific insights, we know a lot about the interior of our planet – even though we’ve never even made it through the crust.

Why Scientists Briefly Thought the Earth Was Hollow
Our understanding of the world has to start somewhere! And while early ideas like the Hollow Earth Theory are mostly wrong and sound silly to us now, that doesn’t mean they weren’t important. Hosted by: Michael Aranda SciShow has a spinoff podcast! It’s called SciShow Tangents. Check it out at ———- Support SciShow by becoming […]
