13 current images from the European Southern Observatory (ESO), the James Webb and Hubble space telescopes, with information about the monthly starry sky.
The detailed text, written by professional astronomers, is unique. It explains exactly what is behind each celestial object. Each calendar page also features a data table showing, among other things, the constellation in which the object is located in the sky.
The calendar includes calendar weeks, moon phases and public holidays. As a special bonus, important celestial events such as the positions of the planets, eclipses and seasons are listed for each month.
A 14th page provides an overview of all the motifs and explains the cover image in great detail.
