Hycean exoplanets are found in the Milkyway and are 2.5 times larger than earth with vast oceans that lie beneath a HYDROGEN-RICH atmosphere. They could host microbial life similar to those extremophiles on earth that surive in the harshest of environments.
I guess life of any size or form is exciting. Not sure how we would communicate with microbes but well who knows?
What good is other life if you cannot communicate in some way? It doesn't necessarily have to be a LANGUAGE but microscopic life does not lend itself to anything like that does it?
I'm not there yet...there being the purpose of it. Are you?
