Jupiter has a surface temperature of around 500 K (Kelvin) which is about 270 C. We have life here that does not only survive, it thrives.

A black smoker or sea vent is a type of hydrothermal vent or underwater hot spring found on the deepest of ocean floors. They are formed in fields hundreds of meters wide when superheated water from below Earth's crust comes through the ocean floor. This water is rich in dissolved minerals from the crust, most notably sulphides. When it comes in contact with cold ocean water, many minerals precipitate, forming a black chimney-like structure around each vent. The metal sulphides that are deposited can become massive sulphide ore deposits in time.

The water at a vent can reach 400 °C (752 °F), but does not usually boil at the sea floor because the water pressure at that depth exceeds the vapour pressure of the aqueous solution. The water is also extremely acidic, often having a pH value as low as 2.8 — approximately that of vinegar. Each year 1.4 × 1014 kg (370 trillion gallons) of water is passed through black smokers.

No one was expecting life to be found here. Once again, man got it wrong. These Black Smokers are teaming with life. Fish and crabs are found here in abundance, along with many other forms of life.  Once again if we have life here in such extreme conditions then surely it stands to reason that there must be life even on such inhospitable planets like the Gas Giant Jupiter.

We have sent probes to Jupiter. They were unable to land, so far. But it does seem that there are places on our planet that are more corrosive to life than that of the surface of Jupiter. It could even be possible that there is life on Jupiter at an advance state. Unfortunately, due to their atmosphere, they can not leave or communicate with others such as us. Not in our Solar System?
