Jupiter’s second Galilean Moon, Europa, with its interior ocean, predominantly crater-less surface, and crisscrosses of cracks and ridges spanning entire hemispheres, makes it one of the most fascinating planetary bodies ever observed. These unique geologic features are possibly indicative of liquid water traveling to the surface from its deep ocean, making Europa a hot spot for the exploration and study of life beyond Earth, also known as astrobiology.

My mind boggles. We haven’t quite created intelligence that exceeds our own, but we appear to be close (for better or for worse I can’t really say.) But I’ve been occasionally suffering from vertigo thinking: I may live to see it. The thing that has fascinated us for so long— The thing that I’ve read and seen in fiction my entire life— I may yet live to see that.

But when we find life somewhere besides upon our precious blue marble… I’m gonna lose my mind. Life on (in?) Europa seems bonkers, right? There’d be absolutely no light in that ocean… and yet. We find the bottom of our own tiny (compared to Europa’s) oceans teaming with life around sources of heat. That sounds exactly like Europa.

Also, you should totally go watch the film, Europa Report . . .

Titan is like Earth with its rivers, lakes, and seas filled by rain, but as stated, this is liquid methane and ethane as opposed to liquid water on Earth. Like Earth, Titan also has sand dunes, but they are made of hydrocarbons instead of silicate-based substances. Also, much like Earth, Titan is known for having a seasonal liquid transport cycle, also known as the water cycle on Earth, linking atmosphere, land, and oceans.

Back in the 1980s I read a lot of science fiction weaving epic tales and describing alien landscapes. These days, I continue to read things which are weaving epic, and describing alien—but they are no longer fiction.
