This website is the creation of photographer Cristiano Justino and it intends to highlight the importance of a night sky free of light pollution.
On April 2007, the International Conference "STARLIGHT A COMMON HERITAGE", promoted by the Canarian Astrophysics Institute (IAC) held on the Canary Island of La Palma (Spain),
promulgated the "Declaration of La Palma in Defense of the Night Sky and the Right to Starlight”, in order to consider heaven a universal heritage to be valued as a cultural,
scientific and landscape resource, and establish the criteria to safeguard this natural heritage.
Man has turned his eyes up to the sky since the dawn of times.
From that constant gazing were born myths, gods and religions, astrology... but also science - Astronomy, the primordial science.
With it, Man was able to recognize stars, planets, commets and satellites.
It provided a means of guidance for Man's journey on exploring and discovering our own planet.
By watching and studying the sky and using Astronomy to measure time - based on the observation of repeated phenomena in the sky - Man created calendars throughout History (lunar and solar calendars), having significantly contributed to agricultural development.
In those days, life was far less agitated than today and allowed for reflection and prolonged and persistant sky contemplation; pollution was pratically inexistant and there were no abondant night lights as there are today.
The night sky presented itself magnificent and inviting, challenging the most imaginative individuals.
"Skygazing put us in contact with Nature, searching for the pleasure of discovery, exploration and evasion."

This photograph shows us the result of earth's rotation for about 1 hour and 30 minutes. Captured in Oliveira do Hospital [PT] during our road trip (Magnificent Skies and Magnificent trees) with a very dark sky, resulting from the low street lighting near the 'Retiro do Tempo - Farm em Terras da Serra da Estrela'.
Star trails are from the constellations of Perseus, Auriga and Taurus (among others), from which we get the strongest trails: white over the tree on the left-> Capella (Auriga); just above the bluish trails-> constellation Perseus; blue lines above the tree on the right-> Pleiades (Taurus).
The Pleiades are an open star cluster with about 200 stars of which 7 are seen without optical aid, in locations with few light pollution.

Light Pollution
examples of inadequate lamppost installation
The public street lighting lampposts come in several different shapes. This 'globe' shape is a perfect example of a bad use of the light source.
This type of lamppost causes light diffusion in every direction except towards the ground, which is the main goal of public lighting.
