13 illustrated, up-to-date images from the European Southern Observatory (ESO), the Hubble and James Webb Space Telescopes, and other observatories – with information on the monthly night sky.
A unique feature is the detailed text, written by expert astronomers. It explains exactly what each celestial object is. Each calendar page also features a data table showing, amongst other things, the constellation in which the object is located in the sky.
The calendars include calendar weeks, lunar phases and public holidays. As a special added bonus, important celestial events for each month – such as the positions of the planets, eclipses and the seasons – are listed.
A 14th page provides a summary of all the illustrations and also explains the cover image in great detail.
