Records for contemplation

“ The wise as an astronomer . As long as you feel the stars as something ‘ above you ’, you still don ’ t have the look of the man who knows .”
— Friedrich Nietzsche

Forming landscapes ... Bodies ... Faces ... Souza Feelings ... Paintings that secrete the past , the present and dreams for the future ... Paintings kept in ethereal boxes that travel in time ... Float in daydreams ... They are rescued by nostalgia ... By memories ... Sources of inspiration ... Records for contemplation ... Human beings have always looked for ways to be able to record the moments they lived through in images . Drawings ... Paintings ... Images in relief ... Large Panels ... Large monuments ... Records for the new generations ... Since ancient times , human beings have been trying to develop ways to obtain images that accurately reveal their observations of the sky . Images of the sky , of the observed phenomena and stars , recorded for posterity . In ancient Greece there are already reports of knowledge of the technique for producing images by directing the passage of light through a small hole , the orifice camera obscura . However , they were images only to be observed when observing the landscape . The Arab Alhazen ( Abu Ali al-Hasan Ibn Al-Haitham ), who lived in the 10th century , presented a way of observing eclipses using a camera obscura .
In this case the camera obscura consisted of a room with a small hole in the window . The image formed on the wall . This method allowed the magnification of the image of the Sun and a comfortable and safe observation of the solar eclipse . The records of the observed images , however , were still made through drawings and paintings . Galileo Galilei released images of his observations through drawings . That way it was possible to get an idea of ​his observations . In the drawings he made , he showed the position of Jupiter ’ s moons , the phases of the planet Venus , details of the Moon and how he observed Saturn . He couldn ’ t get enough resolution to observe Saturn ’ s rings . Sky maps , with representations of how different civilizations saw the constellations , are records that were left by many people . In the West during a long period great artists were responsible for representing the constellations . Beautiful maps of the sky were produced . Works of art . With creative and beautiful designs for each of the constellations . The dream persisted of one day being able to accurately record the observed celestial images . In 1826 , the Frenchman Joseph-Nicéphore Niépce , obtained the first photograph . It was an image from his window . The beginning of a revolution . It was possible to make accurate records of the moments lived . Images for posterity without depending on the precision , technique and talent for drawing of a human being . In 1840 the American chemist and photographer John William Draper obtained what is considered the first astrophotography . He recorded for the first time in a photograph the image of the Moon . In 1880 , his son Henry Draper first obtained an astrophotograph of the Orion nebula . Since that time , the record of images of
