What are biosignatures?

Biosignatures are
visual or chemical clues that signal the presence of life, past or present, in places where scientists won't have the luxury of doing sophisticated laboratory experiments.

Those places include niche environments on Earth as well as possible habitats on other planets and moons of our solar system and on exoplanets and their moons.
