Betelgeuse WILL explode. 💥 When it does, it'll outshine the half Moon and be visible in daylight for months.

TIL Jupiter has a massive inner ocean of liquid metallic hydrogen

Deep beneath Jupiter's outer atmosphere of gaseous hydrogen and helium, crushing internal pressure forces hydrogen into a dense fluid state. Further down, the pressure becomes so high that electrons are squeezed out of the hydrogen atoms, creating a giant mantle of liquid metallic hydrogen.This metallic liquid flows inside the planet like electricity-conducting molten metal, generating Jupiter's massive magnetosphere, which is the strongest magnetic field of any planet in our solar system.
