This isn’t just an odd quirk of the ocean. Scientists warn it’s a disturbing sign of a broader environmental breakdown in progress. As climate change pushes more areas of the deep sea into low-oxygen “dead zones”, key species that help recycle nutrients are disappearing, and with them, the balance of life on the ocean floor.
Paleontologists have uncovered a previously unknown species of sauropod dinosaur in northern Patagonia. The newly named Yeneen houssayi lived around 83 million years ago, adding to the growing body of fossil evidence from the Upper Cretaceous period in Argentina’s Neuquén Basin. The discovery, described as one of the most complete titanosaur skeletons found in the
NASA’s planet-hunting TESS spacecraft recently caught a view of a very different kind of cosmic object: interstellar comet 3I/ATLAS. During a special observation run from Jan. 15 to Jan. 22, the Transiting Exoplanet Survey Satellite (TESS) repeatedly observed comet 3I/ATLAS as it headed out of our solar system. With its wide field of view, TESS
Tucked inside a sunken basin of the Nafud Desert, the town of Jubbah thrives where water once ruled. Surrounded by towering dunes and searing heat, this remote settlement stands out in satellite imagery as a patchwork of vivid green circles, a sign of surprising agricultural life fed by hidden groundwater. A Town Shielded By Sand
While it has become a word, laser used to be an acronym: “light amplification by stimulated emission of radiation”. But there is an even older technology called a maser, which is the same acronym but with light switched out for microwaves. If you’ve never heard of masers, you might be tempted to dismiss them as
NASA’s James Webb Space Telescope (JWST) has captured images of a distant galaxy that is forming a peculiar cosmic structure resembling a question mark. This observation, revealed in a study published by NASA, showcases not only the power of JWST but also the fascinating processes that occur as galaxies collide and evolve. These “cosmic question

New research featured on Nature Climate Change reveals ocean fronts are places where different water masses meet, usually with changes in temperature, salinity, density, and major impacts on carbon dynamics. While they don’t take up much surface space, they’re packed with activity. Until now, they’ve mostly been left out of large-scale climate models, which tend
Europa, one of Jupiter’s 95 moons, is encased in a shell of water ice, and researchers have just re-estimated its thickness. In 2022, NASA’s Juno spacecraft zoomed close to the moon’s surface. Information from this flyby has led researchers to conclude that, in the area where the flyby collected data, the moon’s layer of ice
“Any time there’s dynamic change, there’s the opportunity for new ideas to insert themselves,” Autry said in an interview with Ars. So Autry and others want to give people a chance to voice those ideas by launching the “Space Ideation Challenge.” A challenge for new ideas A prize purse of $125,000 will be awarded to
