Black Trees for Tatooine

I actually don’t remember any trees on Tatooine, but if there were, according to National Geographic, they’d be black.  And According to NatGeo, double sun systems are not at all uncommon.

A third of all star systems, meanwhile, contain two or more stars, and it’s not known how plants might evolve under mixed light sources.

So hypothesizing what plant life would look like and how it would adapt to deal with the effects of a double sun existence is valid research just on the off chance we might some day visit these places.

O’Malley-James and colleagues simulated an Earthlike world orbiting a variety of double- and triple-star systems. Some models contained only red dwarf stars, while others used one red dwarf and one sunlike star, or even two sunlike stars.

Enough light reached the virtual planet to support photosynthesis in most cases, with the world generally seeing as much energy as Earth receives from the sun.

Oh, and if you ever do get there, watch out for the moving plants.  Now that would be interesting adaptation to see.
