|  Neptune's Cloud Mystery The Sun is throwing a cosmic curveball at Neptune! Scientists have been puzzled by the sudden disappearance of the frozen methane clouds that usually adorn Neptune's blue visage. It seems the Sun's UV radiation, ramping up during its 11-year cycle, is the likely culprit. These wispy clouds began vanishing in 2019, gone without a trace by 2020. Even now, four years later, Neptune's skies are still bare. The Sun's unexpected hyperactivity, with double the predicted sunspots, is shaking things up. Astronomers predict it could peak this year, much sooner than anticipated. The Hubble Space Telescope and observatories in Hawaii and California reveal a pattern: solar highs bring more clouds, and lows make them fade away. It's believed that the Sun's UV rays trigger chemical reactions in Neptune's upper atmosphere, leading to cloud formation. This space climate mystery shows how technology and observations connect us to a world 2.5 billion miles away! |
