How are there so many of them?

It provides an incredibly concrete sense of scale for Jupiter's natural satellites, which scientists believe formed from a massive disk of gas and solid debris.While dozens of the gas giant's moons are pretty tiny — crushing only part of Manhattan, for example — the planet's four Galilean moons are far larger, ranging from a diameter of roughly 2,000 miles in the case of Europa to Ganymede's chonky 3,270 miles.
The origin of these four moons is still shrouded in mystery. Europa in particular has long fascinated scientists, as they believe the tiny satellite is covered in a layer of ice with a massive ocean lurking beneath it. That makes it one of theWhile the video only shows animated versions of Jupiter's moons, NASA's James Webb Space Telescope recently got a real-life look, capturing a
