| Far-Out Photosynthesis |
| Topic: Alien Life |
03/15/12 |
| Photosynthesis maintains Earth's habitability for life as we know it, and shapes the way we search for habitable worlds around distant stars. Scientists have discovered a microbe that can use low-energy light to perform photosynthesis. This discovery could alter theories about the types of stars that could support Earth-like worlds. |

| High Planetary Tilt Lowers Odds for Life? |
| Topic: Alien Life |

| Loss of Planetary Tilt Could Doom Alien Life |
| Topic: Alien Life |

| Gravitational interactions between red dwarf stars and habitable planets could erase a world's axial tilt, which moderates global temperatures and creates seasons, before life gets a chance to develop. |

| The Methane Habitable Zone |
| Topic: Alien Life |
11/10/11 |
| In the search for life elsewhere, many studies focus on finding liquid water. But what if life could exist with some other solvent? Saturn´s smoggy moon Titan makes scientists question the possibilities for methane-based life in the galaxy. |
