Neptune's Clouds Vanish as Sun Reaches Fiery Apex

All of Neptune's clouds have disappeared, and scientists believe that the sun's increased ultraviolet radiation due to its heightened activity may be the cause. The clouds began fading in 2019 and were completely gone by 2020. The loss of cloud cover is attributed to sunlight hitting Neptune's atmosphere and triggering chemical reactions that create the clouds. The sun's activity, which follows an 11-year cycle, has been more active than expected, and scientists anticipate it could peak by the end of this year.
