For the first time, astronomers have mapped the vertical structure of Uranus’ ionosphere, uncovering unexpected temperature peaks, weakened ion densities, and puzzling dark regions shaped by the planet’s extreme magnetic field. The results, made possible by nearly a full day of observations with the NIRSpec instrument onboard the NASA/ESA/CSA James Webb Space Telescope, confirm that Uranus’ upper atmosphere has been cooling for decades and offer a rare glimpse into how the ice giant interacts with space in ways unlike any other world in the Solar System.Tie rods et al. mapped the vertical structure of Uranus’ upper atmosphere, uncovering how temperature and charged particles vary with height across the planet.

A 42-year-old man from Britain, Matthew Allick, has spoken about what it was like to die and then be brought back to life after suffering a sudden cardiac arrest. Matthew, who was generally healthy, began to feel unwell at the end of August 2023. He experienced shortness of breath and swelling in his feet, but assumed the changes were because of his new night-shift schedule. The seriousness of his condition became clear when he was unable to climb a single step at work. Realizing something was very wrong, he asked a friend to call an ambulance. At the hospital, Matthew told a doctor that although he hadn’t felt much pain before, it suddenly became unbearable. He described it as “11 out of 10” and then “13,” before collapsing. His heart stopped completely due to a pulmonary embolism—a...

NASA Space Technology NASA has unveiled nine potential landing regions near the moon's South Pole for the Artemis III mission, marking the first crewed lunar landing in over 50 years.These regions, all uncharted by human exploration, will undergo detailed scientific and engineering analyses to assess their suitability for the historic mission.Set for launch as part of NASA's Artemis program, the mission aims to establish the foundation for sustainable lunar exploration.The targeted regions represent an intentional shift from previous lunar landing sites, offering new scientific possibilities in areas where unique geological features, permanently shadowed zones, and possibly preserved lunar resources, such as water, could reveal critical insights."Artemis will return humanity to the moon and visit unexplored areas," Lakiesha Hawkins, assistant deputy associate administrator, Moon to Mars Program Office, said in a statement."NASA's selection of these...
