Mass extinctions are well recognized as significant steps in the evolutionary trajectory of life on Earth. In new research, geobiologists from Virginia...
A major question in Mars history is whether the planet had an ocean in its northern hemisphere. New research provides evidence for a northern ocean or...
In the search for life beyond Earth, subsurface bodies of water in the outer Solar System are some of the most important targets. That’s why NASA and...
About 66 million years ago, a massive asteroid crashed into Earth near the site of the small town of Chicxulub in what is now Mexico. The impact eradicated...
A team of researchers from Curtin University and Peking University has used a supercomputer to simulate how a supercontinent forms and found that because...
Enceladus is one of the prime targets in the search for life in our Solar System. Observations made by NASA’s Cassini spacecraft show that this small...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) and the SPIRou spectropolarimeter on the 3.6-m Canada-France-Hawaii telescope have...
The underwater snow is known to form in low temperature environments, e.g., beneath ice shelves, on Earth. New research led by University of Texas at Austin...
In a study published this week in the journal Nature Communications, scientists tested the hypothesis that fine and coarse marine aerosols have opposite...
Someday, dozens of tiny swimming robots could whisk through the water beneath the icy shell of Jupiter’s moon Europa or Saturn’s moon Enceladus, looking...
After nine years of gathering, cleaning, processing and interpolating data, an international team of researchers this week released the second version...
Otodus megalodon, the largest shark that ever lived on Earth, most certainly reached at least 15 m (50 feet) in total length based on its gigantic teeth....
Mimas, the smallest and innermost of Saturn’s eight main moons, may be warm enough to harbor a global, liquid water ocean beneath a 24-31-km (15-19-mile)...
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...
