Jupiter’s icy moon Europa has an ocean beneath a crust of water ice. Solid carbon dioxide has previously been observed on the surface, but the source...
Dubbed Halomonas phage vB_HmeY_H4907, the new bacteria-infecting virus is the deepest isolated siphovirus from the ocean, and it represents a novel abundant...
Paleontologists have found 130-million-year-old trace fossils from abyssal plain turbidites of the ancient Tethys Ocean. Combined with nannofossil dating,...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered carbon dioxide and methane in the atmosphere of the habitable zone exoplanet...
The evolution of life on Earth has changed dramatically at tens of million-year time scales. However, the causal mechanisms of these changes remain unclear....
Many planetary scientists studying Jupiter’s moon Europa assumed that it formed with a metallic core during or shortly after accretion. New research...
Earth’s rotational pole has drifted toward 64.16°E at a speed of 4.36 cm per year during 1993-2010 due to groundwater depletion and resulting sea level...
Phosphorus has not previously been detected in oceans beyond those on Earth and this discovery provides a promising step forward in our understanding of...
The first records of Greenland Vikings date to 985 CE. Archaeological evidence yields insight into how they lived, yet drivers of their disappearance in...
The subsurface ocean of Jupiter’s icy moon Europa is heated from below via tidal heating and radioactive decay of the rocky interior, while being cooled...
The new model provides a high-resolution understanding of how today’s geophysical landscapes were created and how millions of tons of sediment have flowed...
University of Washington researcher Baptiste Journaux and colleagues believe the newly-created substances could form at the surface and bottom of deep...
When ocean-bearing moons begin to cool down, their oceans can freeze. As new ice accretes to the bottom of the existing ice shell, the added volume of...
Mimas, a small moon of Saturn, is heavily cratered and lacks the typical characteristics of an ocean-bearing moon, such as the active surface of Enceladus....
Enceladus, the sixth-biggest moon of Saturn, is a top candidate in the search for extraterrestrial life in the Solar System.
An artist’s impression of...
Using data from the NASA/ESA Hubble Space Telescope and NASA’s retired Spitzer space telescope, astronomers have discovered that two exoplanets around...
The Chicxulub-like asteroid crash landed in shallow ocean waters in the Martian region of Chryse Planitia 3.4 billion years ago (Hesperian period) and...
An analysis of chromium isotopes in Martian meteorites suggests that approximately 4.5 billion years ago, there was enough water for the entire planet...
The Devonian period, which occurred 419 to 358 million years ago, prior to the evolution of life on land, is known for a series of catastrophic mass extinction...
