Cores de Exo-Terras Poderiam Indicar Habitabilidade
|
| Topic: Alien Life |
11/09/12 |
| Summary: Quando a detecção direta de planetas semelhantes à Terra se torna possível, cientistas querem ser capazes de facilmente caracterizar estes planetas e ver quais deles podem ser apropriados à vida alienígena. Uma nova técnica mostra como as cores únicas de ambientes particulares, que se sabe abrigarem vida extremófila na Terra, podem ser detectadas remotamente. |

Colors of ExoEarths Could Indicate Habitability
|
| Topic: Alien Life |
11/09/12 |
| Summary: When direct detection of Earth-like planets becomes possible, scientists want to be able to easily characterize these planets and see which ones might be suitable for alien life. A new technique shows how the unique colors of particular environments known to harbor extremophile life on Earth can be detected remotely. |
