Cygnus Loop’s splash of color
“The layers and structures of the Cygnus Loop are so sophisticated,” American photographer Min Xie said of the supernova remnant visible in this “highly praised” image in the 2021 “Stars and Nebulae” category.
“This is an image that every astronomer and astrophotographer wants to see at least once in his life: the entire pure remnant of the supernova Cygnus, cleared of all disturbing elements,” said László Francsics, judge of the competition. “As a result, this iconic and tranquil bubble structure emerges out of the dark, with countless details. This astroimage is a one-of-a-kind photograph.”
