When astronomers discover a planet orbiting another star, they can easily deduce its size, temperature, and chemical makeup. But even the most powerful telescope cannot relate what the planet truly looks like. For that, scientists have historically relied on artistic interpretations. Now physicist Abel Méndez of the University of Puerto Rico at Arecibo has developed a more accurate resource: software that transforms a constellation of data points into a realistic planetary portrait.
The program, called the Scientific Exoplanet Renderer, or SER, takes in observational information about the planet and its parent star, crunches the numbers in various physical models, and spits out an approximate likeness. It can visualize many breeds of planets and atmospheres, but it is intended for those that resemble Earth, such as damp, potentially cloud-covered HD 85512b (below).
Méndez, who will make the program available to scientists next year, hopes the detailed visualizations will help them interpret ...
