light pollution is largely the result poorly designed lighting, which wastes energy shining outward to the sky, where it is unwanted, instead of downwards to the ground, where it is needed. billions are spent each year on unshielded outdoor lights, though they are directly responsible for 14.7 million tons of carbon dioxide waste in the u.s. alone.
our overlit cities and suburbs have radically altered the light rhythms to which many forms of life, including diurnal animals such as ourselves, have adapted, disrupting the migratory, reproductive and feeding cycles of nocturnal creatures in potentially devastating ways.
light, for example, makes nocturnal animals easier prey, and acts as a magnet for birds, with the latter effect so powerful that scientists speak of some birds being literally “captured” by searchlights, circling in the thousands until they drop. the effect was notably observed in new york’s tribute of lights.
the effect on humans is just as profound. darkness is not only essential to our biological welfare (with links to breast and prostate cancer), but the light of the stars and the rhythms of day and night is part our collective evolutionary and cultural patrimony. yet, two thirds of humanity live under skies polluted with light, while one fifth of planet can no longer see the milky way.

ILLUMINATED CODE FROM SPACE
Bioartis Haari Tesla (behance) - "Macrocosm and microcosm is an ancient Greek Neo-Platonic schema of seeing the same patterns reproduced in all levels of the cosmos, from the largest scale (macrocosm or universe-level) all the way down to the smallest scale (microcosm or sub-sub-atomic or even metaphysical-level). In the system the midpoint is Man, who summarizes thecosmos." - I was doing some researches and I found experiment with miniatures of space so I decided to try my own. The result has been nebulae, galaxies and supernovae transformed into microorganism.
The Giant Magellan Telescope - GMT
WIth the James Webb telescope launch set for 2015, the GMT, and a lot more telescopes being built, the questions of our universe almost seem to be closer and closer waiting to be solved. I wrote about the GMT almost a year ago and it quickly became one of my favorite telescopes. It will be operational in 10 years the engineers say. I don’t know if that’s too short or too long. Either way let me tell you a little about this amazing telescope.
The Namesake - Magellan
Ferdinand Magellan, everybody knows the famous explorer, he led an expedition in 1522 which was the first to circumnavigate the earth, an ambitious feat for exploration. Astronomy was the primary tool of navigation of that time and Magellan was a certainly a student of astronomy. The expedition saw in the southern hemisphere obscure clouds in the night sky, later named the Magellanic Clouds. These clouds turned out to be island universes, filled with millions of stars orbiting another island universe, our Milky Way.
The Giant Magellan Telescope will continue the tradition of exploration that was set forth 500 years ago. The telescope is also peering into the unknown, maybe finding new questions to our Universe and searching for new worlds.
The Telescope - A Giant
The GMT will utilize a new and unique design. There will be seven 27ft segmented mirrors surrounding a central segment forming a single optical surface. This precision will give the telescope a resolving power 10x that of the Hubble Telescope. The light will be concentrated into CCD (Charge Coupled Device) image cameras which will measure the distance of objects and what their composition is.
This is Where is Gets More Interesting
The telescopes segmented mirrors are flexible. Under each mirror there are hundreds of ‘actuators’ that constantly adjust the mirrors to counteract atmospheric turbulence. These actuators will turn flickering stars into sharp points of light.
High and Dry
A huge advantage is the location of the GMT. Located in Chile in the Atacama Desert at an altitude of approximately 8,500 ft it is the highest and driest location on Earth.
The Giant Magellan Telescope (GMT) project - has passed two major reviews and is positioned to enter the construction phase.
