Introduction The telescope is an instrument which increases our ability to observe far away objects through the collection of electromagnetic radiation‚ the most prevalent type of telescope is the optical telescope which collects light‚ however there are other kinds of telescopes which collect UV and X -Rays. Optical telescopes use lenses to redirect light to a specified point. Different lenses are used for different magnifications of celestial objects. This essay will be mainly discussing

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

Galileo Galilei | Galileo Galilei was the first astronomer to use a telescope to study the heavens. Galileo made a number of observations that finally helped convince people that the Sun-centered solar system model (the heliocentric model)‚ as proposed by Copernicus‚ was correct. What is a Galilean telescope? The original design Galileo Galilei came up with in 1609 is commonly called a Galilean telescope. Galileo’s telescope with which Jupiter’s moons could be observed was made with a plano convex
