The image depicts a vintage illustration of solar protuberances, rendered in a monochromatic reddish-brown hue. The protuberances appear as swirling, flame-like structures extending from the surface of the sun, creating a dynamic and ethereal effect. The illustration is reminiscent of early astronomical drawings, with a focus on capturing the shape and texture of these solar phenomena. The background is a deep, saturated shade of red, enhancing the contrast and highlighting the intricate details of the protuberances. The image is framed by a thin black border, and the bottom of the image features text that reads 'SOLAR PROTUBERANCES.'
