| A new study suggests that rocky super-Earths might cool down very slowly after their formation, making them hotter than previously thought. The research could have implications in understanding how "Earth-like" these planets truly are. |

| Heavy elements – ‘metals’ in astronomer-speak – are created within stars and then spewed out across the cosmos by supernovae. Scientists are now asking: when did the Universe have enough metals to start building planets? |

| When Stellar Metallicity Sparks Planet Formation |
| Topic: Cosmic Evolution |

| New research predicts the criteria needed for Earth-like planets to form around a star that have one-tenth the metallicity of our Sun. If researchers find small, rocky planets orbiting stars with lower metallicity, it may challenge the presently accepted “core accretion” model of planetary formation. |

| How to Keep Lonely Exoplanets Snug – Just Add Dark Matter! |
| Topic: Cosmic Evolution |

| Dark matter, inferred to exist from its gravitational effects on the universe, is still a mystery to scientists. But a new study says that dark matter could help life evolve and survive on distant worlds outside of our solar system. |

| A bias in the way amino acids twist could be due to supernovae, researchers now suggest. If correct, this could be more evidence that the molecules of life came from elsewhere in the cosmos. |
