NASA discovers X-shaped structures in Earth's ionosphere, puzzling scientists
Summary: NASA's GOLD mission discovered X- and C-shaped structures in Earth's ionosphere, affecting radio and GPS signals. The ionosphere's density fluctuates due to sunlight and external events like solar storms. GOLD observed X shapes without such disturbances, suggesting lower atmosphere impacts. C-shaped bubbles, possibly wind-related, were also seen close together. Understanding these anomalies is crucial for signal reliability. Scientists are puzzled by these unexpected phenomena.
