Black plants 'could grow' on exoplanets with two suns
Zitat:
Plants on distant hospitable planets could have developed black foliage and flowers to survive, according to a new study.
Flora that would appear black or grey to human eyes could have evolved on planets orbiting dim "red dwarf" stars, according to unpublished research that is being presented at the National Astronomy Meeting in Llandudno, Wales.
This would enable plants to absorb more light to photosynthesise, using their star's light to convert carbon dioxide into organic compounds.
