The atmosphere of Jupiter is largely made up of hydrogen and helium gas. It would be a horrible idea to try to land on Jupiter. You'd be subjected to incredibly high temperatures and would be stranded in mid-Jupiter with no possibility of escaping. The only place on Jupiter where it might be possible to survive is at the south pole, but even there you'd need a suit that protects you from the cold.
The interior of Jupiter is mostly hydrogen and helium with some rock deep down. There may be other elements present in the crust but we have no way of knowing since Jupiter's surface is covered by a huge cloud layer.
All in all, Jupiter is quite a dangerous place to live because of the heat and pressure. Anyone who tries to land on its surface will be instantly vaporized.
Astronomers use telescopes to look at things that are far away from Earth. They use instruments called "telescopes" to see these objects. Sometimes they want to see how much matter there is in stars or galaxies beyond the Milky Way galaxy. So they make observations of these objects and analyze the data they get from their observations. This is known as "astrophysics."
There are many different types of telescopes. Some people call them optical telescopes because they can see colors by using lenses or mirrors to bend light into different directions.
Surface. Jupiter, as a gas giant, lacks a real surface. While a spaceship would have no place to land on Jupiter, it would also be unable to sail through unharmed. Spacecraft attempting to enter the planet are crushed, melted, and vaporized by the tremendous pressures and temperatures deep within the planet. A few spacecraft have managed to survive this fate, but none have ever been found again.
Jupiter has four major moons: Io, Ganymede, Europa, and Callisto. None of these bodies is able to support life as we know it; all are frozen shells of ice. However, they do contain significant amounts of water ice, which may in turn contain traces of other materials that could be useful for living organisms.
Io is the most volcanically active body in the Solar System. It is covered by an enormous ocean that melts when heated from below by its molten core. This is probably why it is so rich in water ice. The energy released by the resulting volcanic activity helps to keep Io's interior warm, allowing more ice to melt into its oceans.
Ganymede is larger than Earth's moon and the only body in the Solar System with an atmosphere. It was once thought to be the largest moon in the Solar System, but recent studies have shown it to be merely large compared to the rest of the small bodies in the Solar System.
A few spacecraft have made it into orbit, but none has ever successfully landed on Jupiter.
Jupiter's moon Io is the most volcanically active body in our solar system. Active volcanoes erupt sulfur dioxide, hydrogen chloride, and other chemicals that form a thick atmosphere over much of the moon. The heat from these eruptions creates the intense magnetic fields that circle both Jupiter and Io.
Landers are vehicles designed to land on planets' surfaces for scientific investigations or resource extraction. Because Jupiter has no solid surface to land on, scientists have never attempted to do so. However, its four large moons provide many opportunities for landing.
Europa has a dense layer of ice beneath a hard shell that may contain water molecules trapped in crystal lattices. This would make Europa very different from any other world in our solar system. Ganymede, the largest moon of Jupiter, is mostly ice with a crust of rock and a deep ocean of liquid oxygen and hydrogen under pressure. Callisto, the third moon out from Jupiter, is completely covered by an icy crust thousands of feet thick.
Jupiter is a turbulent planet with fierce storms and no solid surface. It has a surface temperature of -110 degrees Celsius, but its lower atmosphere is incredibly hot! If there was life here, it would have to exist in the higher atmosphere. It would burn up if it dwelt in the lower atmosphere. Life as we know it requires energy and atoms to build itself up. Jupiter gets all its energy from the sun and does not contain enough matter to create additional atoms or energy.
The great mass of Jupiter keeps on turning around its axis at a rate too fast for us to see or feel; but this movement produces many waves which travel through the planet's interior. These waves carry energy along with them and when they reach the center they cause it to vibrate. This vibration is what gives rise to Jupiter's mighty winds.
Jupiter is also subject to great changes in gravity. The gravitational force on an object is determined by the mass of the object and the distance from the source. Because Jupiter is so large it causes a greater change in gravity near its surface than something like the moon. The closer you get to the sun the more intense its heat becomes, so close to Jupiter it would be very hot indeed!
It has been suggested that because Jupiter has such extreme conditions, perhaps there is life out there somewhere else in the galaxy waiting for someone to come and visit? This idea comes from where?
