NASA and ESA are trying a new interplanetary Internet

NASA and the European Space Agency (ESA) have success an experimental version of interplanetary Internet to control the educational robot astronauts to the International Space Station. Used in the experiment, a new protocol developed by NASA Disruption Tolerant Networking (DTN) allowed to send messages and demonstrated that once between spacecraft can create a network of information sharing, such terrestrial Internet.

Color exoplanets can tell about its fitness for life support

The new technique, proposed by scientists, allows the color of exoplanets judge about her extremophiles - organisms that can survive in extreme conditions.

Usually extremophiles hiding deep in the earth, but sometimes they are found on the surface or close to it. Scientists from the Max Planck Institute for Astronomy, Germany, Siddharth Hedge and Lisa Kaltenegger investigated a number of places in which extremophiles live on the surface of the Earth, 

Frequent collisions of comets expose secrets that existed 17 years

Every 6 seconds for millions of years the comet have a collision with one another near the star lying in the constellation Cetus, which can be seen on the night sky with the naked eye.

The star, called 49 China, for a long time did not allow scientists to rest - it was unclear how the star, which is about 40 million years, so can surround a giant cloud of gas, usually associated with younger stars.
