Observe and photograph Comet Ison
Discovered on 21 September 2012, Comet ISON will pass close to the Sun at the end of November 2013 before heading back towards Earth (there is no risk of collision!).
From the beginning of December, Comet ISON could become the most spectacular object visible in the northern hemisphere, sweeping across the night sky with its immense plume of gas and dust for several weeks.
Taking advantage of this exceptional event and the European Rosetta probe's entry into orbit around a comet in spring 2014, Le Grand Livre des Comètes explains what astronomers currently know about these beautiful wanderers.
Written in clear language accessible to readers aged 12 and over, it summarises the latest discoveries about these amazing celestial bodies, which tell us about the formation of the Solar System and may well have been the source of the abundant water on our planet, and even of the life that has developed there over several billion years.
The second part of the book offers detailed maps and a wealth of practical advice on how to find, observe and photograph Comet ISON from October 2013 to spring 2014.
