Astronomers create array of Earth-like planet models
Ithaca NY (SPX) Jun 22, 2015
To sort out the biological intricacies of Earth-like planets, astronomers have developed computer models that examine how ultraviolet radiation from other planets' nearby suns may affect those worlds, according to new research published June 10 in Astrophysical Journal. "Depending on the intensity, ultraviolet radiation can be both useful and harmful to the origin of life," says Lisa Kaltenegger, Cornell associate professor of astronomy and the director of Cornell's new Carl Sagan Institute: Pale ... read more
