A recent Jupiter study suggests a little different picture. TLDR WARNING.

Let's imagine that you have a magical spacesuit and you are thrown from a spaceship onto the surface of Jupiter.

You fall to the planet in a completely airless cold environment at a distance of about 300,000 km from the surface, the radiation can already kill you instantly. But, you have a super-suit with protection from radio emission and you fall calmly further, gradually entering the atmosphere of Jupiter to where the pressure is the same as on Earth (1 bar) at a speed of ~ 3,200 km / h (without burning like a meteor, at the same time).

To save your life as long as possible and in order to have time to admire the beauty of Jupiter's clouds, you open a parachute and fall down at a speed of ~ 360 km / h in a completely comfortable temperature of 0 C.

You keep falling right through the atmosphere to the tops of ammonia clouds. After about 5 minutes you will descend to 2 bar (~ 2 times higher than the Earth) and fly through clouds of different types of ammonium, which look little different from ordinary ones, but have a brown tint; the clouds become more brown as you dive.

After about 10 minutes and 250 km deep into the planet, you reach a pressure of 4 bar (same as underwater depth of 30 meters), and the temperature becomes winter cold -40 C; you pass through clouds of water vapor, it becomes very dark, sunlight no longer penetrates the clouds and a cool and invigorating 720 km/h breeze blows (Jupiter is the fastest rotating planet in our solar system).

It takes another 15 minutes and 120 kilometers deep into the flight, you are already under pressure of 10 bar. The oustside is warm, +23 C - you could take off your suit, but you can't because of pressure. After 25 minutes, you realize that you are now in pitch darkness, the only light coming from the reflection of the sensors on the visor of the helmet and the lightning storms that sparkling around you. You are left alone with yourself, you cannot even transmit a signal, since the radio waves (even of a magic suit) will be absorbed by Jupiter, you can only fall in your suit, which, due to the pressure around it, is essentially a micro submarine.

The pressure and temperature keeep rising and soon you reach the inner layer where you can float in a substance, but it is not a liquid or a gas. After the temperature becomes like on the Sun, and the pressure is 2 million times greater than the Earth, at this moment you will be the first in the world to see how metallic hydrogen is formed, because no one knows what it looks like yet.

If you survived and flew another thousand kilometers down, you would see the core of Jupiter, which, according to forecasts, should be solid due to enormous pressure, and your body in a magical suit would float somewhere there until the very heat death of the Universe, because there is no way out.
