Authors: Yu.G. Shevelev , V.A. Marsakov , . ... We have constructed and investigated properties of metallicity function of disk stars with different ages, proceeding from the statistically restored real altitude distributions of stars at the solar galactocentric distance. It is shown that the metallicity distribution of stars in each age range is not of Gaussian form, but it may be considered as a superposition of two normal distributions centered at -0.2 and 0.0 dex. ...

An atom is the smallest "piece" of an element that still has the properties of that element. For example, an atom of gold is the smallest piece of gold that still acts like gold ? ... When many atoms come together, atoms tend to form molecules. A molecule is a combination of two or more atoms bonded together. For example, a molecule of water (designated by the symbol H 2 O) consists of two hydrogen atoms and an oxygen atom which are in a "relationship" ? ...

The infrared satellite IRAS. The main task of the IRAS telescope was the search of a longwave infrared radiation, composing the maps of the sky in the infrared range. IRAS telescope helped to discover new galaxies, to study the properties of the dust particles in our galaxy, which opens the character of a star hiding somewhere in the sky. ... For 6 months of observation it discovered 6 new asteroids, allowed to find out the nature of the dust zones between Mars and Jupiter orbits. ...

... Acceleration of particles in the vicinity of a massive black hole We propose a two-step mechanism for charged particle acceleration in the magnetosphere of a massive black hole surrounded by an accretion disk. Particles first gain energy by stochastic process during the accretion phase. It is shown that effective proton acceleration up to energies eV is possible in the turbulent magnetized accretion disk. ...
