A 6,000 year old telescope without a lens - prehistoric tombs enhanced astron... Astronomers are exploring what might be described as the first astronomical observing tool, potentially used by prehistoric humans 6,000 years ago. They suggest that the long, narrow entrance passages to ancient stone, or 'megalithic', tombs may have enhanced what early human cultures could see in the night sky, an effect that could have been interpreted as the ancestors granting special power to the initiated. The team present their study at the National Astronomy Meeting, being held this week in Nottingham. The team's idea is to investigate how a simple aperture, for example an opening or doorway, affects the observation of slightly fainter stars. These structures could therefore have been the first astronomical tools to support the watching of the skies, millennia before telescopes were invented. The project targets how the human eye, without the aid of any telescopic device, can see stars given sky brightness and colour. Media contacts NAM 2016 press officeTel: +44 (0)115 846 6993

Land | Copernicus Discover Land The Copernicus Land Monitoring Service (CLMS) provides geographical information on land cover and its changes, land use, vegetation state, water cycle and Earth's surface energy variables to a broad range of users in Europe and across the World in the field of environmental terrestrial applications. It supports applications in a variety of domains such as spatial and urban planning, forest management, water management, agriculture and food security, nature conservation and restoration, rural development, ecosystem accounting and mitigation/adaptation to climate change. CLMS is jointly implemented by the European Environment Agency and the European Commission DG Joint Research Centre (JRC) and has been operational since 2012. CLMS consists of five main components: The systematic monitoring of biophysical parameters produces mainly a series of qualified bio-geophysical products on the status and evolution of the land surface.

The Drake Equation "What do we need to know about to discover life in space?" How can we estimate the number of technological civilizations that might exist among the stars? While working as a radio astronomer at the National Radio Astronomy Observatory in Green Bank, West Virginia, Dr. Frank Drake conceived an approach to bound the terms involved in estimating the number of technological civilizations that may exist in our galaxy. Where, N = The number of civilizations in The Milky Way Galaxy whose electromagnetic emissions are detectable. R* = The rate of formation of stars suitable for the development of intelligent life. fp = The fraction of those stars with planetary systems. ne = The number of planets, per solar system, with an environment suitable for life. fl = The fraction of suitable planets on which life actually appears. fi = The fraction of life bearing planets on which intelligent life emerges. L = The length of time such civilizations release detectable signals into space.
