Far-Out Photosynthesis
|
| Topic: Alien Life |
03/15/12 |
| Summary: Photosynthesis maintains Earth's habitability for life as we know it, and shapes the way we search for habitable worlds around distant stars. Scientists have discovered a microbe that can use low-energy light to perform photosynthesis. This discovery could alter theories about the types of stars that could support Earth-like worlds. |

Una fotosíntesis poco convencional
|
| Topic: Alien Life |
03/15/12 |
| Summary: La fotosíntesis mantiene la habitabilidad de la Tierra para la vida tal como la conocemos, y nuestro conocimiento de este proceso biológico condiciona la forma en que buscamos mundos habitables alrededor de estrellas distantes. Ahora los científicos han descubierto un microbio que puede utilizar luz de baja energía para realizar la fotosíntesis. Este descubrimiento podría alterar las teorías sobre los tipos de estrellas que podrían sostener mundos como la Tierra. |
