A striking image of a spiral-shaped sunspot captured on February 19, 1982, by the Vacuum Solar Telescope at Kitt Peak. This unusual sunspot, approximately 50,000 miles across, is a testament to the dynamic and surprising nature of solar activity. The dark areas represent cooler regions (around 4,000 degrees Celsius) compared to the surrounding solar surface (6,000 degrees Celsius).
