portions abundant in pyrobitumen—a solid organic carbon residue formed when buried oil or organic matter undergoes high‑temperature alteration. These specimens were extracted from drill cores of the Zaonega Formation curated by the Geological Survey of...

the lander relayed measurements and images to the orbiting bus, which beamed the data back to Earth. Despite confronting temperatures and pressures that imposed severe thermal and mechanical stress, Venera 13 kept transmitting for 127 minutes. First...

Located roughly 3,000 kilometers beneath the surface, the lowermost mantle is a zone defined by extreme pressure and temperature. While scientists have understood for decades that this area contains significant variations in density and chemical...

disappeared behind its star. By measuring these mid-infrared signals, researchers were able to calculate the dayside temperatures of HD 3167 b. If the planet were a bare rock devoid of any gas, it would reach a specific, predictable temperature based on...

the atmosphere would retain enough carbon dioxide—much of which will persist for millennia—to keep the Earth’s temperature approximately 1.5 degrees Celsius above preindustrial levels. “We know that fossil fuel emissions have caused a lot of warming,...

Beryl Rappaport of Syracuse University has identified a new species of amoeba capable of surviving and thriving in temperatures once thought to be lethal for eukaryotic life. The discovery, detailed in a study published in the journal Cell, pushes the...

NASA’s Artemis II heat shield successfully withstood 4,000°F temperatures, with new inspections revealing a significant tenfold reduction in material damage. NASA engineers have successfully demonstrated that fine-tuning the reentry path of the Orion...

that equilibrium isotope fractionation between gas and mineral surfaces can dramatically alter these ratios. As temperatures fall, physical chemistry dictates that deuterium atoms will preferentially partition into condensed solid phases rather than...

and proton nuclear magnetic resonance studies argued that appreciable hydrogen bonding might still endure at extreme temperatures and pressures. Complicating matters further, X-ray Raman spectroscopy revealed a spatially heterogeneous picture,...

forcing an eclipsed configuration and a significantly shorter interplanar distance of roughly 3.9 angstroms. Variable-temperature ssNMR spectra of BA2SnI4 and DABSnI4 acquired across their respective phase transition temperatures. (a) 13C spectra of...

this new complex relies heavily on electronic factors to dictate its photophysical behavior. Dual Emission and Temperature-Dependent Behavior When irradiated with ultraviolet light in powder or thin-film forms, the compound yields a striking blue-green...
