Mapping the Chemistry Needed for Life on Europa
|
| Topic: Europa |
04/09/13 |
| Summary: A new study shows that hydrogen peroxide is present over much of the surface of Europa. If hydrogen peroxide mixes through the icy surface and into the water ocean below, it might be an important energy source for life. |

Complex Chemistry in Titan's Lower Atmosphere
|
| Topic: Titan |
04/06/13 |
| Summary: Scientists previously thought that chemistry in Titan's atmosphere became more inert closer to the surface. Now, a new study suggests that complex organic chemistry that could lead to the building blocks of life extends lower in the moon's atmosphere than previously thought. |
