JÁ EXISTIU VIDA EM MARTE? Descoberta incrível revela dados sobre a vida no planeta vermelho

Cientistas estão encontrando evidências de que Marte provavelmente era um planeta com rios.

Geólogos identificaram os remanescentes antigos e erodidos de rios em várias crateras em Marte.

Isso foi possível graças aos dados coletados pelo rover Curiosity da NASA na cratera Gale, uma grande bacia de impacto na superfície de Marte.

Na Terra, os rios são importantes para os ciclos químicos, de nutrientes e de sedimentos, todos têm um impacto positivo na vida.

A descoberta de evidências adicionais de rios antigos em Marte, portanto, pode ser um desenvolvimento importante na busca por sinais de vida no Planeta Vermelho.

Segundo os cientistas, a descoberta apresenta uma visão mais otimista da vida antiga em Marte.

O Curiosity já havia confirmado anteriormente que a cratera Gale, com 154 km de diâmetro, já foi preenchida com água líquida.
