Most of the images taken by the satellite have clouds obscuring much of the surface, and Dr. Sullivan, and others, have selected nights when the cloud cover is negligible or very light. We show here one such image to give a flavor of the things that can be seen. The Earth at Night poster also includes a strong display of northern lights, seen from above, of course. Inc. We are an International, membership based non-profit organization interested in preserving mankind's view of the Universe as seen on a prime dark sky night, now so sadly lacking to most inhabitants of the Earth. We are also interested in promoting quality nighttime lighting as an essential step in preserving these dark skies.
Light pollution is clearly an environmental issue.
See the IDA Information Sheets of more details. We welcome your membership. In spite of this, these images are very effective in calling attention to the issues of light pollution.
