Many thanks to @12tone for lending his voice for the Sagan/Salpeter quote.

Gas giants are often thought of as being inhospitable to life, especially the ones in our solar system. But as early as 1976 Carl Sagan himself together with Edwin Salpeter already speculated on the possible existence of life in the clouds of Jupiter. They show that abiogenesis could be possible in Jovian conditions, and even create a the speculative alien biosphere. And even if we cannot find life on Jupiter, Saturn or any other of our solar system's gas giants, perhaps life is present on exoplanets somewhere in the galaxy. In fact, the brown dwarf WISE 0855-0714 has recently been put forward as suitable for life. Speculative biology artist Charlotte Veldhuizen also put forward several interesting vision for gas giant-based life on an exoplanet in her "Project C" describing a group of inhabited stars called "The Cluster".

Speculative science is the central theme of my channel, where I apply mainstream science & humanities to analyse topics as diverse as astrobiology, alternate history and pop culture symbolism. My main focus right now is on alien biosphere evolution, but I will also regularly revisit alternate history, which is the most popular topic on my channel.
