A rare annular solar eclipse, often referred to as a 'ring of fire,' is set to grace the skies above remote Antarctica on February 17, 2026. During this spectacular event, the moon will obscure approximately 96% of the sun, leaving a brilliant ring of sunlight visible around the lunar disc. This phenomenon, known as an annular eclipse, occurs when the moon is farther away from Earth in its orbit, making it appear smaller and unable to completely cover the sun.
