Alien landscape. Artwork of the surface of a volcanic planet orbiting a brown dwarf star (upper left). A brown dwarf is a cool star, or a large planet, that is insufficiently massive for nuclear reactions to be ignited. Instead, it would shine faintly, mostly by infrared heat radiation as it slowly collapses by gravitational contraction. Here the brown dwarf has a smaller blue-white companion star (upper right, behind rock).
