Novel Bacterial Proteins From Seafloor Shine Light On Climate And Astrobiology
Gigatons of greenhouse gas are trapped under the seafloor, and that’s a good thing. Around the coasts of the continents, where slopes sink down into the sea, tiny cages of […]

Do Oceanic Convection and Clathrate Dissociation Drive Europa's Geysers?
Water vapor geysers on Europa have been inferred from observations made by the Galileo spacecraft, the Hubble Space Telescope, and the Keck Observatory. Unlike the water-rich geysers observed on Enceladus, […]
