Introduction 1.1 Scope The aim of this book is to describe how a simple reflecting telescope can be made with the materials and facilities available in India. As the primary goal is to popularize telescope making‚ only the most primitive (but effective) constructions will be considered; the emphasis will be on the practical aspects of telescope making. Some excellent books on this subject are in print (see‚ for example‚ the Bibliography). Yet few people have easy access to these books as they

A few weeks ago NASA approved the work on the space telescope Transiting Exoplanet Survey Satellite‚ TESS‚ wich will be sent to orbit on 2017 with the mission of finding exoplanets. Exoplanets are planets that orbit a star that is not our sun‚ and until now scientists have discovered over 800 of them‚ mainly thanks to the Kepler telescope wich began working in 2009. TESS goal is to identify planets within the habitable zones of nearby stars. This mainly means planets with a solid crust and with temperatures
