Exotic solvents & life's building blocks are among the more speculative
#astrobiology topics, but still important to study scientifically! Our own system contains places potentially able to host life unlike on Earth. Not just Titan!

All Earth life is carbon-based and needs water to survive. 💦
'Mildly' exotic life might share these traits, but use e.g. other information molecule (or differently coded DNA, even with different/more 'letters') or opposite chirality (left/right-handedness) of some compounds.

There are countless possibilities of different information molecules and their coding. Is Earth DNA and RNA a ', frozen accident', or does it have a phys/chem reason? And is all life chiral? In the same way, or is that another frozen accident? What about the amino acids we use?
