Yearbook of Astronomy 2020/Ежегодник по астрономии 2020

Издание на английском языке
The Yearbook of Astronomy 2020 is the latest edition of what has long been an indispensable publication, the annual appearance of which has been eagerly anticipated by astronomers, both amateur and professional, for well over half a century and which is approaching its Diamond Jubilee edition in 2022. As ever, the Yearbook is aimed at both the armchair astronomer and the active backyard observer. Within its pages you will find a rich blend of information, star charts and guides to the night sky coupled with an interesting mixture of articles which collectively embrace a wide range of topics, ranging from the history of astronomy to the latest results of astronomical research; space exploration to observational astronomy; and our own celestial neighbourhood out to the farthest reaches of space.
The Monthly Star Charts have been compiled by David Harper and show the night sky as seen throughout the year. Two sets of twelve charts have been provided, one set for observers in the Northern Hemisphere and one for those in the Southern Hemisphere. Between them, each pair of charts depicts the entire sky as two semi-circular half-sky views, one looking north and the other looking south.
Summaries of the observing conditions for each of the planets, as well as a calendar of significant Solar System events occurring throughout the year, are included in the Yearbook, with The Planets in 2020 and Some Events in 2020.
The ongoing process of improving and updating what the Yearbook offers to its readers is continued in the 2020 edition with the introduction of apparition diagrams for Mercury and Venus and finder charts for Uranus and Neptune.
These are described in more detail in Using the Yearbook of Astronomy as an Observing Guide.
Lists of Phases of the Moon in 2020 and Eclipses in 2020 are also provided.
Suggestions from readers for further improvements and additions to the Yearbook are always welcomed. After all, the book is written for you …
