Submission + - Worlds With Two Suns May Sport Black Plants (

sciencehabit writes: If Tatooine were real, it would probably be filled with black plants and trees. A new study finds that, to maximize energy absorption for photosynthesis, the flora on worlds that orbit two suns may have evolved to use one or more types of light-absorbing pigments that absorb across a broad range of wavelengths, which would tend to make the plant appear black or gray. Although the idea that planets that could host such life may sound far-fetched, such orbs may not be so rare: The teamâ½ Â s computer simulations indicate that Earth-like planets can exist in several types of stable orbits in multistar systems. More than one-fourth of the sunlike stars in our galaxy and about half of the long-lived but dim, cool stars called red dwarfs are found in solar systems containing two or more stars, the researchers note.
