| Europa's Acid Ice Fields |
||
| From Slashdot:
"The New Scientist reports on recent observations that suggest the ice on Jupiter's moon Europa may be highly acid with a pH of near zero, and have a surface layer of hydrogen peroxide. Two theories have been put forward. One says that the acid has been formed at the surface layer from oceanic salts reacting with the intense radiation from Jupiter, the other that sulphuric acid is coming directly from the ocean, with the water reacting with sulphur produced from undersea volcanos. Wilst reducing the chances of life on Europa, it is not ruling it out completely, as there are terrestrial extremophile bacteria which thrive in highly acid environments." http://www.newscientist.com/...
