Scientists just recorded a huge eruption on one of Jupiter’s moons

While Jupiter’s moon Europa is suspected to host a hidden ocean — boosting the possibility of alien lifeforms — its sibling Io has a reputation for being a lot more destructive.

Hundreds of volcanoes continuously erupt over Io’s surface, thanks to the gravitational tug-of-war between Jupiter and its other moons.

Some blasts are so powerful that they can be seen from telescopes on Earth.
