It can be called the morning or evening star, depending on where you are or what time it is, but it is anything but a star; in fact it is one of our nearest planetary neighbours, Venus.
The waters off Iceland rank among the world’s most productive fisheries. The reason for the abundance is an ample supply of phytoplankton, the base of the marine food chain. Like any plant, microscopic phytoplankton need sunlight and nutrients to survive. Iceland’s coastal waters offer both during the long days of summer.
What about situations we can’t know to be prepared for, such as, well, alien invasion? If you wonder if we actually have an alien-contact contingency plan watch this video.
Our understanding of what lies beneath the world’s biggest ice sheet has taken another leap forward. In this video we strip away Antarctic ice to reveal a new, and much more detailed map of the bedrock below. This map, called Bedmap2, was compiled by the British Antarctic Survey and incorporates millions of new measurements, including substantial data sets from NASA’s ICESat satellite and an airborne mission called Operation IceBridge.
Gravity is one of the fundamental forces of nature, its invisible grip governing our planet – from the rocks inside to the seas on the surface. However, getting a grip on gravity on a global scale can only be done from space, and that’s something ESA’s GOCE satellite mission has been doing since 2009. One of the ultimate goals of GOCE is to improve our knowledge of the geoid, a kind of ‘gravity map’ of the planet, that is essential for oceanographers, surveyors, engineers and Earth-science researchers.
You won’t see the universe the same way after watching this. Including totally new perspectives on the earth’s surface, the sun, the stars, and life.
