Photograph of our closest star made using special h-alpha band solar telescope.
In this extremely narrow bandpass we can observe beautiful structures of deep atmosphere of the Sun (chromosphere) and prominences - pillars of plasma chained in extremely strong magnetic field - here visible as characteristic structures on the edge of the visible solar disk.
Due to the edge darkening phenomenon and special post-processing, our closest star looks like a large three-dimensional ball suspended in the void of space.
Artist: Łukasz Sujka. For over 10 years associated with amateur astronomy and photography of the night sky. He enjoys exploring still undiscovered areas of astrophotography and still looking for new challenges such as the photography of Venus sulfuric clouds, the Moon's mineral colors, colliding galaxies, Albert Einstein’s gravitational lensing and others. However, his greatest passion is the large-scale photography of the Solar System objects - planets, the Moon and our closest star - Sun (using a dedicated solar telescope). Łukasz is a laureate of many prestigious awards - including win in the category of "Planets, comets and asteroids" in the largest astrophotography competition in the world - "Astronomy Photographer of the Year 2020" and second place in the international competition Astrocamera 2020. His works are also regularly recognized as Image of the Day on Astrobin portal.
