This image captures a close-up view of the sun's corona, which is typically invisible to the naked eye due to its distance from Earth. The corona appears as a bright, circular ring around the sun, exhibiting a stark contrast between the darker center and the lighter outer edges. This effect is primarily due to the temperature difference within the corona; it's much hotter at the outer edges than in the center. The corona emits a brilliant yellow-orange glow, which suggests extreme temperatures of about 2 million degrees Celsius. These high temperatures cause the sun's light to radiate more intensely in certain directions, leading to this vibrant coloration. This phenomenon is known as thermal radiation. In addition to the bright yellow-orange glow, the corona also emits a faint red glow. This can be attributed to the presence of highly charged atoms within it. These atoms are excited by the extreme temperatures and emit light at specific wavelengths, resulting in this soft red hue. Overall, this image provides a stunning depiction of one of nature's most powerful phenomena - the sun's corona.
