Southern Europe is once again in the grip of extreme summer heat. Soaring temperatures and bone-dry land have fuelled widespread wildfires, with the Iberian Peninsula among the regions hardest hit.
Editor’s Note: This article was updated Aug. 20, 2025, to correct the number of years of training data used and the model accuracy. The original article said the model was trained on 14 years of Solar Dynamics Observatory data and surpassed existing benchmarks by 15%; the model was actually trained on 9 years of data and […]

As we observe National Aviation Day Tuesday – a tribute to Orville Wright’s birthday – let’s reflect on both America’s and NASA’s aviation heritage and share how we are pushing the boundaries of flight for the nation’s future. Modern NASA grew from the National Advisory Committee for Aeronautics (NACA), an agency created by Congress in […]
A collaboration between NASA and the small business Aloft Sensing produced a new compact radar system that will enable researchers to leverage High Altitude Long Endurance (HALE) platforms to observe dynamic Earth systems. This new radar is small, provides highly sensitive measurements, and doesn’t require GPS for positioning; eventually, it could be used on vehicles […]
