SETI – The Search for Extraterrestrial Intelligence
Image by encouragement
"The search for extraterrestrial intelligence (SETI) is the collective name for a number of activities undertaken to search for intelligent extraterrestrial life. SETI projects use scientific methods in this search. For example, electromagnetic radiation is monitored for signs of transmissions from civilizations on other worlds. Some of the most well-known projects are run by Harvard University, the University of California, Berkeley, or the SETI Institute. In 1995, the United States federal government ceased funding to SETI projects, forcing them to turn to private funding to continue the search, though in recent years, government funding of SETI has resumed at modest levels."
"There are great challenges in searching the cosmos for signs of intelligent life, including their identification and interpretation. SETI projects use the best available scientific knowledge to conduct experiments, which has traditionally led to searches for electromagnetic radiation emitted by advanced technologies."

Archive: Gulf of Finland (NASA, International Space Station, 07/10/05)

Editor’s Note: for World Water Day, a beautiful retro image from 2005, showing the sunglinted waters of the Gulf of Finland. If water could be set on fire…this is how it would look.
The Gulf of Finland is featured in this image photographed by an Expedition 11 crew member on the international space station. This strongly oblique view shows the Gulf of Finland and Lake Ladoga in the sunglint of late afternoon. The image was taken from the station when the position of the craft lay north of the Caspian Sea, approximately 2,500 kilometers to the southeast on the Russia–Kazakhstan border.
The Neva River appears in sunglint, connecting Lake Ladoga to the gulf. Although not visible, St. Petersburg—the home town of Sergei Krikalev, space station commander when this picture was taken—lies on the Neva River delta. In this view taken with a powerful 400 millimeter lens, sunglint even reveals the causeways to Kotlin Island in the gulf—including some of the details of their construction.
Oblique views reveal marked layers of gray haze generated by air pollution, a common sight over Western Europe. Pollution also renders the bright glint areas a copper color.
About Crew Earth Observations:
In Crew Earth Observations (CEO), crewmembers on the International Space Station (ISS) photograph the Earth from their unique point of view located 200 miles above the surface. Photographs record how the planet is changing over time, from human-caused changes like urban growth and reservoir construction, to natural dynamic events such as hurricanes, floods and volcanic eruptions. A major emphasis of CEO is to monitor disaster response events in support of the International Disaster Charter (IDC). CEO imagery provides researchers on Earth with key data to understand the planet from the perspective of the ISS. Crewmembers have been photographing Earth from space since the early Mercury missions beginning in 1961. The continuous images taken from the ISS ensure this record remains unbroken.
