Curiosity found on Mars, radiation is not dangerous for humans


Radiation levels on the surface of the Red Planet is equivalent to environment radiation in low Earth orbit, NASA discovered Martian rover Curiosity.

The first measurements of radiation levels - the first held on the surface of another planet - can cheer those who want to see how once on Mars for the first time set foot on the person: Curiosity rover found that people may well spend some time on the surface of the Red Planet.

supernova nuclear blasts produce a paste


When dying stars detonate as supernovae, spread out a shock wave lead the so-called "rebound" - matter and elementary particles are compressed towards the center of the star to achieve the density that come into play in the nuclear force.

In the development of a supernova nuclear particles can create different and often bizarre forms, such as rods, plates or vials and long threads - which gave the name to this phenomenon, associated with the famous Italian pasta. Creating a "paste" because in the dying star DIURNAL two types of forces - the Coulomb revulsion of the same charges and nuclear forces of attraction.

Meteorites found on Mars there is warm water


Hydrothermal cracks around Martian impact craters could be suitable places for living organisms, according to scientists.

The new study, manner jointly by the University of Leicester and the Open University, led by lead author John Bridges of the University of Leicester has determined that the temperature on Mars were in the range of about 50 to 150 degrees Celsius. On Earth, microbes can survive in such an environment, such as the volcanic thermal hot springs of Yellowstone National Park, USA, suggest the researchers.
