Critters from a brown-dwarf world would likely be able to see infrared pretty well, in fact, since that's the majority of their sun's output. Plant(like) lifeforms on the world would probably be black, to our eyes, so as to absorb the maximum possible EM radiation.No argument. Habitable planets around bodies like a red dwarf or brown dwarf would only be habitable thanks to having an atmosphere capable of creating convection around the planet so as to distribute the heat more evenly around the surface. They'd have to be tidally locked in order to be within the habitable zone at all. But astronomers looking at exoplanets these days have been running plenty of simulations for how a tidally-locked world around such a star (they haven't considered brown dwarfs, but given the existence of Titan it's only a matter of waking up to the possibility really) could exist and keep liquid water at the surface. That was the answer they came up with- if the atmosphere is thick enough, then convection patterns in the atmosphere distribute the heat and make a more habitable planet. The weather probably isn't very interesting by our standards, since it'd constantly flow in about the same directions, but it can be done.Nice idea! Life around a neutron star; I like that. Might work for a black hole too, though those usually have accretion disks and I'd think that would screw things up a bit. Of course, accretion disks put out lots of radiation, so perhaps that would just tend to make the black hole more of another star.</blockquote>
