Io: A Moon So Violent, It Shouldn't Exist

[Webster]

Io is unlike any other moon in the solar system.

It spews lava hundreds of kilometers into space, melts from the inside out, and orbits over 390 million miles from the Sun… and yet, it's the most volcanically active body we know.

In this video, we dive deep into the science, chaos, and mystery behind Jupiter’s most violent moon—Io. From its bizarre chemistry to the constant eruptions that reshape its surface, we'll explore why this moon shouldn't even exist… and how it might hold the key to understanding alien worlds, extreme energy systems, and planetary evolution.
