The Dark Energy Survey (DES) is a survey that aims to probe the dynamics of the expansion of the universe and the growth of large scale structure. The collaboration is composed of research institutes and universities from United States, Brazil, United Kingdom (UK), Germany and Spain. The survey will use the 4-meter Victor M. Blanco Telescope located at Cerro Tololo Inter-American Observatory (CTIO) in Chile, and the main innovation of that project consists in the development of a new camera which is commonly called DECam. This camera will allow astronomers to take more sensitive images in the red part of the visible spectrum and in the near infrared, in comparison to current equipment installed at Victor M. Blanco Telescope. In addition, DECam has one of the widest field of view available for ground-based optical and infrared images. According to the official website, its field is so large that a single image will record data from an area of the sky 20 times the size of the moon as seen from the earth. The survey will image 5000 degrees of the southern sky and will take five years to complete.

Famous quotes containing the words dark, energy and/or survey:
“When Americans look out on the world, they see nothing but dark and menacing strangers who appear to have no sense of rhythm at all, nor any respect or affection for white people; and white Americans really do not know what to make of all this, except to increase the defense budget.”
—James Baldwin (1924–1987)
“After the planet becomes theirs, many millions of years will have to pass before a beetle particularly loved by God, at the end of its calculations will find written on a sheet of paper in letters of fire that energy is equal to the mass multiplied by the square of the velocity of light. The new kings of the world will live tranquilly for a long time, confining themselves to devouring each other and being parasites among each other on a cottage industry scale.”
—Primo Levi (1919–1987)
“In a famous Middletown study of Muncie, Indiana, in 1924, mothers were asked to rank the qualities they most desire in their children. At the top of the list were conformity and strict obedience. More than fifty years later, when the Middletown survey was replicated, mothers placed autonomy and independence first. The healthiest parenting probably promotes a balance of these qualities in children.”
—Richard Louv (20th century)
