Sunspot Looking out into Space ? Siu Fone Tang (USA) [Photo/The Royal Observatory Greenwich’s Astronomy Photographer of the Year 13 (2021) competition/exhibition]
This image shows a close-up of a sunspot and the plasma as it flickers and follows the magnetic lines generated by the Sun. The photo depicts what is called the chromosphere, this is imaged using a hydrogen-alpha filter. The photo is made up of multiple frames that are stacked together and then later enhanced using Photoshop. It is an inverted view which creates more contrast.
