Moonless development – Simulations 4 billion years of development of the Earth without the presence of the Moon. Were performed in the Research Center of NASA in Moffett Field, California by Jack Lisauer. In the developed model, the maximum angle at which leaned to the axis of the Earth, turned out to be much smaller than assumed earlier studies. The conclusions of the study were: Earth would be the Earth even without his extremely large satellite.

Cząsteczki z przestrzeni – Gaz pierwotny
Cząsteczki z przestrzeni – Gaz pierwotny – Has been confirmed the hypothesis about the origin of molecules from space. The researchers were able to discover the so-called. Primary gas, which was created shortly after the Big Bang, it consists of hydrogen and its heavier isotope deuterium. This finding confirms that in the Big Bang were created only the lightest chemical elements, hydrogen and helium. Heavier elements appeared only after 100 million years.
