Earth in the third dimension

The German satellite TanDEM-X was launch into orbit on a mission to map more accurate to be made available to the surface of the Earth. The satellite will fly radar technology with identical platform called TerraSAR-X launched in 2007. Both measured variations in the height of the globe with an accuracy of better than two meters.

Its digital elevation model will have many uses, from helping military jets fly ultra low height to show where rescue workers was worse the damage caused by an earthquake.

Significance makes Earth look like a potato

A satellite is record variations in Earth's significance gives us a different view of our planet from space looks like a potato. And yet, the information provided by this model is the sharpest view we have of how gravity varies across the Earth. The device was released by the team working on the European satellite GOCE.

Are a new type of planets and dark alone?

U.S. astronomers discovered what they explain as a new class of planets: 10 dark bodies floating lonely far from any host star. The discovery was detected in the center of the Milky Way. The scientists, who published the findings in the journal Nature, believe these planets, which are the size of Jupiter, were expelled from their original planetary systems.

According to Professor David Bennett, professor of astrophysics and cosmology at the University of Notre Dame in Indiana,
