A recent study...
NASA/Conceptual Image Lab, Wes Buchanan, and Krystofer Kim NASA scientists have confirmed the existence of a third global energy field encircling Earth, known as the ambipolar electric field. This newly discovered field plays a crucial role in propelling charged particles into space from the poles. Historical Context and Existing Fields Traditionally, Earth’s global energy fields have been...

Researchers globally, with significant contributions from McGill University and...
Earth has sweltered through its hottest day on record this weekDepositphotos Earth experienced its hottest day on record twice this week. According to data from the Copernicus Climate Change Service (C3S), Sunday initially set the record for the highest global average temperature since records began in 1940, only for Monday to surpass it. On Sunday, July...

Much like atmospheric oxygen is crucial for animals, dissolved oxygen (DO) is key for the health of aquatic ecosystems, whether in freshwater or marine environments. Given that billions of...
Artist's impression of a giant asteroid hitting the Earth – something China hopes its upcoming mission will one day help preventDon Davis/NASA China is aiming to enter the field of planetary defense. A recent paper by the China National Space Administration (CNSA) reveals plans for a test mission in 2030 to deflect a small asteroid...
Credit: Pixabay Just over ten years ago, a robotic rover on Mars provided a long-awaited answer to a critical question: it confirmed the presence of organic material buried in the sediment of the planet's ancient lakebeds. Since then, we have continued to discover organic molecules on Mars, distributed in a manner indicating widespread carbon chemistry on...
Scientists have proposed that Earth’s moon-sized inner core revolves independently of the mantle and crust, and that it is now backpedaling relative to those other layers.JOHAN63/ISTOCK/GETTY IMAGES PLUS A new study seems to support the contentious idea that the Earth's inner core's rotation has decelerated. Decades of earthquake data indicate that since around 2010, the...
Credit: Depositphotos A new study has confirmed that Earth's inner core rotation has indeed slowed, raising questions about the central dynamics of our planet and potential impacts on us. Researchers from the University of Southern California (USC) believe this alteration in the core’s rotation might slightly lengthen our days, though only by fractions of a second—so...
