Life on other planets would likely be brief and become extinct very quickly, according to a new paper by astrobiologists at the Australian National University. In research aiming to understand how life might develop, the scientists realised new life would commonly die out due to runaway heating or cooling on their fledgling planets. “The universe […]
Harvard-Smithsonian scientists speculate that little green men may not be “green” at all, and finding them might be a simple matter of looking for industrial pollution in the atmospheres of exoplanets. The remote analysis of distant planets for signs of pollution is discussed in the latest issue of The Astrophysical Journal and the scientists who […]
Pivoting planets that lean one way and then change orientation within a relatively short time period might be surprisingly habitable. That’s according to NASA scientists who say the climate effects generated on these wobbling worlds could prevent them from turning into glacier-covered ice lockers, even if those planets are somewhat far from their stars. “Planets […]
