LONDON - Mysterious gassy planets spotted outside the Earth's solar system may not be hospitable to life as we know it, but rocky moons orbiting them might, US scientists said yesterday.
Dr Darren Williams and colleagues at Pennsylvania State University said they had identified two systems that might have planets with such moons. In a letter to the science journal, Nature, they suggested "that the systems belonging to 47 Ursae Majoris and 16 Cygni B should be considered as possible abodes for extraterrestrial life."
