Complex life on Europa?

New study suggests that the Jupiter's satellite Europa Could contain in its ocean an elevated concentration of oxigen, that could allow the presence of complex multicelluler life... see the article here http://www.universetoday.com/2009/10/08/europa-capable-of-supporting-life-scientist-says/#more-42303

Great news!!

your comment please...

I have always thought that we would find fish and marine animals on Europa, whether or not the papers say it could happen. I can't wait to meet them ^_^

Alternatively this could be doom for any Europan biosphere. Oxygen is toxic to anaerobic organisms, it could rip prebiotic molecules to shreds. It'd be a very interesting result if there had been life on Europa, which was extinguished by rising oxygen levels.

Yes indeed, that's what I was thinking. Oxygen is quite reactive. I'm not quite sure how they got this new oxygen estimate anyway, so I sort of left the topic alone.

infact, the study estimates that the oxigen reached the Europa's ocean only 2 billion years later its formation, allows life to rise.
