FSS will show how many such signals are on a given body, if any.The FSS wil give a "likelihood" of finding bio sites on a given planet though.
For me, O class star systems produce the most biological signals. I've found so many that I no longer go down to the plants and drive around and take pictures. I just map the planets and move on.Update Typically second system of the night I have found my second biological signal![]()
