A duo of MIT researchers has created the most detailed atlas of the world’s largest oxygen deficient zones, biogeochemical regions of the global ocean...
Extreme warming at the end of the Permian period induced profound changes in marine biogeochemical cycling and animal habitability, leading to the largest...
The end-Ordovician mass extinction, the first of the ‘Big Five’ mass extinctions occurred 445 million years ago and was characterized by the disappearance...
New research led by the Observatoire astronomique de l’Université de Genève suggests that water never condensed and that, consequently, oceans never...
Dr. Manasvi Lingam from the Department of Aerospace, Physics and Space Sciences at the Florida Institute of Technology and Professor Avi Loeb of Harvard...
Hycean worlds are composed of water-rich interiors with massive oceans underlying hydrogen-rich atmospheres; with densities between those of rocky super-Earths...
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...
