Typhoon Sinlaku Sparks Upper-Atmosphere Gravity Waves

NASA’s Earth Observatory reports that Super Typhoon Sinlaku’s rapid intensification generated atmospheric gravity waves visible as mesosphere airglow in VIIRS imagery from NOAA-20, while complementary stratospheric waves were detected by AIRS on Aqua; as the cyclone strengthened from category 2 to 5, the waves radiated outward in a cone, highlighting how convection in intense storms can influence the upper atmosphere and potentially improve storm monitoring and weather/space-weather forecasting.

Unveiling the Enigmatic Green Ghosts: Astronomers Capture Spectroscopic Data for the First Time

Astronomers have successfully captured spectroscopic data from a mesospheric green ghost for the first time. These green ghosts, which appear during thunderstorms as a greenish glow on top of transient luminous events (TLEs), were previously speculated to be excited oxygen atoms. However, the researchers found evidence of nickel, iron, nitrogen, and oxygen in the green ghost, suggesting that it resulted from meteoric ablation of interplanetary dust particles moving through the atmosphere at high speed. The team's years-long effort to capture this data sheds light on the nature of atmospheric green ghosts.

"NASA's Atmospheric Waves Experiment Reveals Mesosphere's First Images in 'First Light'"

NASA's Atmospheric Waves Experiment (AWE) has captured its first images of the mesosphere from the International Space Station (ISS), confirming the instrument is functioning as designed. AWE aims to study atmospheric gravity waves (AGWs) in the mesopause region to understand how they form and their effects on the upper atmosphere. This research is crucial for comprehending space weather impacts on satellite operations and communication systems. AWE is led by Ludger Scherliess at Utah State University and managed by NASA's Goddard Space Flight Center.

Artificial Meteor Shower Launch Set for 2025.

Space start-up ALE is set to create the world's first artificial meteor shower, named 'SKY CANVAS', over Japan in 2025. Metallic, pea-sized spheres will be dropped from a satellite 250 miles up, which will glow upon re-entry into the atmosphere, appearing as shooting stars. The light show will not only be for viewing pleasure but will also help gather data about the mesosphere, a region that is difficult to study. The project aims to inspire a greater interest in space and science and contribute to the sustainable development of humankind.
