"Tholins: Mysterious Brown Space Goo" -- did oxidizing it lead to life on Earth?




“Tholins: Mysterious Brown Space Goo Found Everywhere but Earth”


Anton Petrov notes the observation of this nitrogenous organic matter on Titan (really good landing through the fog), Europa cracks, Pluto, Triton, and even an asteroid.

Oxygen destroys tholins, which is why we don’t find them on Earth, and probably destroyed on Mars.

But some bacteria can thrive inside tholins in the laboratory.   

Carl Sagan had discussed the substance back in his book in the 1980s.
