Researchers using NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) have discovered a high-speed jet stream sitting over Jupiter’s equator, above the main cloud decks. At a wavelength of 2.12 microns, which observes between altitudes of about 12-21 miles (20-35 kilometers) above Jupiter’s cloud tops, researchers spotted several wind shears, or areas where wind speeds…

However, many European forests removed less CO2 from the atmosphere during the extremely hot and dry summer of 2022, according to a new European study. The findings…

The study, led by the University of Oxford, rules out a meteorite impact, suggesting instead that the quake was the result of enormous tectonic…
This artist’s conception shows a newly formed protostar surrounded by a swirling protoplanetary disk of dust and gas. Credit: University of Copenhagen/Lars Buchhave When stars are born, they do it inside a molecular cloud. Astronomers long assumed that the “crèche” supplied all the nutrients that protostars needed to form. However, it turns out they get…
Concept of the high-temperature electrothermal process (HET) for soil remediation. a Schematic of the HET process, combined with vacuum extraction well. The vacuum piping and insulation blanket remain standard to known thermal remediation methods, but in the case of HET, the electrodes provide a rapid voltage pulse for electric heating, rather than long-duration heat injection….

The turbulent velocity power spectrum of NGC 6946 as a function of baseline. Credit: arXiv (2023). DOI: 10.48550/arxiv.2310.02661 Indian astronomers have conducted a study aimed at investigating a large-scale turbulence in the interstellar medium of a spiral galaxy known as NGC 6946. Results of the study, published October 4 on the pre-print server arXiv, could…
Credit: Shutterstock There is growing consensus that our planet is likely to pass the 1.5℃ warming threshold. Research even suggests global warming will temporarily exceed the 2℃ threshold, if atmospheric carbon dioxide (CO₂) peaks at levels beyond what was anticipated. Exceeding our emissions targets is known as a climate overshoot. It may lead to changes…
The graphic shows the water temperatures around the Antarctic. On the western side of Antarctica, water temperature at the sea floor is approaching 2 degrees C—and that is warm enough to melt the ice that is flowing on top of it. Sea temperatures on the eastern flank are colder. Credit: Dr Benjamin Davison, University of…
Variable spore map where colors depict F. oxy spore concentration in soil [spores g−1]. The map was built using the web map of global F. oxy distribution as a foundation (Calderón et al 2022). We calculated an F. oxy survey effort ratio which reduces the geographical biases that the web map inevitably shows. This ratio…
