About Jupiter's Core: Gleason, we can find out lots of stuff about planets and stars even though we can't go there and "touch" them. In Jupiter's case, we have sent spacecraft to orbit and to fly by it, the biggest planet of them all. The spacecraft can send radio waves towards the planet and "listen" for their echos. Radio waves can penetrate the various layers of gas in Jupiter's outer layers, and return a "picture" of what's inside, just like an X-ray. Some of these things we can do from the Earth, too. By the way, Jupiter has no hard surface, like the Earth, it just gets denser and denser towards the middle. For farther objects that we can't yet reach with spacecraft, like distant stars and galaxies, we can analyse their light to determine what they're made from. There are PLENTY of books on planets and stars in the library. Check 'em out! (literally!) Have fun. |
