Algae, moss and micro organism can all survive and develop within the mild produced by a pink dwarf star, in line with experiments on Earth. This boosts the concept that that planets round pink dwarf stars like TRAPPIST-1 might host life.

Probably the most promising exoplanets for all times orbit stars which are smaller and cooler than our solar, so that they radiate totally different profiles of sunshine. As an example, a star like TRAPPIST-1 would give out extra …
