Experiments on Earth mimicking the rays from a red dwarf star show that cyanobacteria, algae and moss can grow under these light conditions, backing the idea that some exoplanets could host life

Algae, moss and bacteria can all survive and grow in the light produced by a red dwarf star, according to experiments on Earth. This boosts the idea that that planets around red dwarf stars like TRAPPIST-1 could host life.
The most promising exoplanets for life orbit stars that are smaller and cooler than our sun, so they radiate different profiles of light. For instance, a star like TRAPPIST-1 would give out more …
