How deep could you penetrate a gas giant like Jupiter where hydrogen turns into a liquid metal at its core?

The problem with trying to fly through a gas giant like Jupiter is that “the density, pressure and temperature all increase to such enormous levels as you penetrate down into the interior that it is impossible the penetrate any probe through. Near the center of Jupiter, the normally gaseous hydrogen turns into a liquid metal, making this region as exotic as the surface of the sun. To give a sense of the pressure near the center of Jupiter, consider the Mariana Trench on Earth, the deepest place in our oceans. At nearly 7 miles (11 km) deep, pressures reach just over 1,000 bars (100,000 kilopascals), which would feel like 8 tons of pressure per square inch (703 kilograms per square meter). At sea level, you experience about 1 bar of pressure (100 kilopascals). Near the center of Jupiter, pressures jump to megabars, or one million bars, Fletcher said. On top of those enormous pressures, temperatures also rise into the tens of thousands of Kelvins, which is equivalent to tens of thousands of degrees Celsius. At that point, any spacecraft wouldn’t be just squished or melted — it would entirely disintegrate into its constituent atoms.
