Saltier Oceans Could Have Prevented Earth From Freezing
The Sun shone 20% less brightly on early Earth, and yet fossil evidence shows that our planet had warm shallow seas where stromatolites -- microbial mats -- thrived. Now a study may have solved the "faint young Sun paradox," showing that saltier ocea.....»»
Formation of super-Earths proven limited near metal-poor stars
In a new study, astronomers report novel evidence regarding the limits of planet formation, finding that after a certain point, planets larger than Earth have difficulty forming near low-metallicity stars......»»
Chemical chameleon reveals novel pathway for separating rare-earth metals
Researchers at the Department of Energy's Oak Ridge National Laboratory have found a chemical "chameleon" that could improve the process used to purify rare-earth metals used in clean energy, medical and national security applications......»»
Could comets have delivered the building blocks of life to ocean worlds like Europa, Enceladus and Titan?
Throughout Earth's history, the planet's surface has been regularly impacted by comets, meteors, and the occasional large asteroid. While these events were often destructive, sometimes to the point of triggering a mass extinction, they may have also.....»»
