Erupções Solares Assassinas Não Destruirão a Terra em 2012
|
| Topic: Spaceship Earth |
11/16/11 |
| Summary: As condições meteorológicas espaciais podem afetar profundamente o planeta Terra. Erupções solares são capazes de interromper a comunicação com satélites e ejeções de massa coronal podem até danificar redes de energia na Terra. Mas mesmo no seu pior, erupções e ejeções de massa do Sol não são capazes de destruir a Terra. |

| Topic: Spaceship Earth |
10/18/11 |
| Summary: A new study is providing information about how radiation from space can damage life on Earth, and shows that a short gamma ray burst would be more significant than a longer gamma ray bust. If one of these bursts of energy occurred nearby, it could have lasting effects on Earth's surface and oceans. |
