Paleontologists have discovered the exceptionally well-preserved, 3.42-billion-year-old filamentous microfossils in a paleo-subseafloor hydrothermal vein...
Earth’s sphere tilts on its axis at an angle of 23.5 degrees; this gives us our seasons, with parts of the planet receiving more direct sunlight in summer...
Observations from NASA’s Cassini spacecraft established that Enceladus, the sixth-largest of Saturn’s moons, has a global subsurface ocean. An analysis...
Jupiter’s moon Europa harbors underneath a tectonically modified ice shell a salty ocean in direct contact with its rocky interior. Such an oceanic environment...
A novel theory proposed by planetary scientists from Caltech and NASA’s Jet Propulsion Laboratory challenges the current thinking that the saltwater...
Radionuclides are ubiquitous in sediment and rock, where their decay leads to the production of hydrogen and oxidized chemicals via radiolysis of water;...
In a study published this month in the journal Icarus, planetary researchers from the United States and Germany modeled chemical processes in the subsurface...
Paleolithic people deliberately crossed the challenging ocean to migrate to the Ryukyu Islands of southwestern Japan, even though the islands would not...
Marine biologists from the United States and the United Kingdom have recorded over 100 deep water-dwelling cutthroat eels, identified as Ilyophis arx,...
Europa, the sixth of Jupiter’s moons and the fourth largest, has a subsurface ocean covered by an icy shell. Despite evidence for plumes on the icy moon,...
Large tidal ranges from the Late Silurian to the Late Devonian epoch (420 to 380 million years ago) could have fostered both the evolution of air-breathing...
The end-Permian mass extinction, also known as the Permian-Triassic extinction event and the Great Dying, is the largest mass extinction event in Earth’s...
An international team of scientists has found interstellar iron-60, a radioactive isotope with a half-life of 2.6 million years that is predominantly produced...
A team of scientists from Europe, the United States, Canada, South Korea, Greenland and China has produced the most detailed depth map of the Arctic Ocean...
A team of biologists from Japan and the United States has successfully revived aerobic microbes found in 101.5-million-year-old sediments from the abyssal...
A team of microbiologists at Caltech has discovered a species of bacterium that feeds on manganese, one of the most abundant elements on Earth.
This SEM...
A duo of U.S. planetary scientists has calculated that water in the subsurface ocean of Jupiter’s icy moon Europa could have been formed by breakdown...
Two teams of marine biologists have found methylmercury, a potent toxin that bioaccumulates in marine food webs, in sediments and endemic fauna from Mariana,...
Pluto is thought to possess a subsurface ocean beneath its thick ice shell. It has generally been assumed that the dwarf planet formed out of cold material...
