Astronomers have recently found hundreds of new exoplanets, or planets beyond our own solar system. While nobody knows what the view would be like from these planets' surfaces, we can make educated guesses--and illustrations--based on information gleaned by researchers.

Gliese 876D, for instance, has an orbit tighter than Mercury's and a solid mass several times that of Earth, and it may rotate so slowly that sunrise, imagined here, unleashes a fiery hell. The planet's red dwarf star, dominating the horizon, could trigger violent internal tides, leading to monumental volcanic eruptions. A glowing orb of a moon hangs in a blood-red sky, its thin atmosphere shredded by stellar winds.
