Are the gas giants and stars only composed of gas particles? Don't they have a solid crust or something? If they don't have a solid part then how can they exist alone?
Some gas giants have liquid cores. Some may potentially have solid cores. But for the most part, they're primarily made out of gas. If you ever fell into a gas giant, you'd likely be crushed by the pressure of the atmosphere long before you struck anything solid (or liquid).Allen_Wolf said:Are the gas giants and stars only composed of gas particles?

Stars are too hot for anything like this. They're composed of plasma, which is a form of matter where electrons aren't bound to atoms. Stars may have differing compositions (heavier elements tend to fall towards the cores of stars), but they're composed of plasma through-and-through.
How do you think stars are held together? Why do you think Earth has an atmosphere?Allen_Wolf said:But how can they stay compact even without a solid core?

No, gas giants and stars do not have a solid surface. They are primarily composed of gas and plasma, with no solid surface to stand on.
Gas giants and stars are primarily made up of hydrogen and helium gases, with smaller amounts of other elements such as carbon, nitrogen, and oxygen. Stars also have a significant amount of plasma, which is a hot, ionized gas.
No, it is not possible to land on a gas giant or a star due to their lack of solid surface and extreme temperatures and pressures. Any spacecraft or object attempting to land would be crushed and vaporized.
Yes, there are exceptions. Some of the moons and planets orbiting gas giants, such as Jupiter's moon Io, have solid surfaces that could potentially be landed on. However, these surfaces are still highly inhospitable due to extreme conditions.
Yes, scientists use various methods such as remote sensing, spectroscopy, and computer simulations to study the interiors of gas giants and stars. These methods provide valuable information about their composition, structure, and behavior without the need for physical exploration.
