Oceans on Earth may have all been green for eons before they turned blue
Earth's oceans may have been green for billions of years until the first photosynthetic organisms flooded our atmosphere with ...
Deep-sea organisms shape ocean floor at 7.5 km depth
Traces of organisms detected in sediments from 7.5 kilometers below the ocean surface reveal how organisms living in the deep sea are engineering their own environments. Analyses of sediment cores ...
Jupiter's moon Callisto is very likely an ocean world
More pocked with craters than any other object in our solar system, Jupiter's outermost and second-biggest Galilean moon, Callisto, appears geologically unremarkable. In the 1990s, however, NASA's ...
