Japanese scientists have found recorded on the Earth from space stardust particles, which were formed before the formation of the solar system. They are contained in two small meteorites found in the deserts of Morocco and Algeria.
In Tokyo today published the results of their research, conducted with the help of the latest microscope by a team from the capital's Industrial University and several other institutions.
Stardust — is scattered in space particles of minerals formed mainly of atoms dying and exploding stars. Such cosmic grains of sand are the main "raw material" for the formation of our Earth and other planets. By studying them, researchers, in particular, hope to clarify the history of the origin of solar and other stellar systems.
In African Japanese meteorites found seven grains ranging in size from 0.1 to 1 micron (one ten-thousandth to one thousandth of a millimeter), presumably separated from two different stars to the birth of the solar system, whose age is estimated to be 4.6 billion years old. According to the chemical composition of the particles belong to the class of silicates — the most important rock-forming minerals, constituting 80% of the earth's crust. ITAR-TASS.
