BBC Sky at Night - 2021 Full Year Collection

BBC Sky at Night magazine is a British monthly magazine about astronomy aimed at amateur astronomers and published by Immediate Media Company. Its title is taken from the television program produced by the BBC, The Sky at Night. The magazine, in comparison with the TV series, includes more technical and scientific information. Until 2015, it also included a bonus CD-ROM with software programs, latest astronomical photographs, written materials and 'classic' episodes of The Sky at Night from the BBC archives (from 2015, the monthly content was moved online).Wikipedia
