The recent results obtained by the modern telescopes and spacecrafts allow us for the first time to compare directly the mass , spatial density and size distribution of the dust grains in the regions of their production , processing and consumption in our Galaxy .
The ALMA and VLT/SPHERE telescopes allow us to estimate the production of the dust by supergiants and collapsing core supernovae .
The 2MASS , WISE , SDSS , Planck and other telescopes allow us to estimate the processing of the dust in the interstellar medium .
After renewed Besançon Galaxy model the medium appears to contain about half the local mass of matter ( both baryonic and dark ) in the Galactic neighborhood of the Sun .
The Helios , Ulysses , Galileo , Cassini and New Horizons spacecrafts allow us to estimate the consumption of the dust into large solid bodies .
The results are consistent each other assuming the local mean spatial density of the dust is about of 3.5 \times 10 ^ { -26 } g/cm ^ { 3 } , mean density of the grain is about 1 g/cm ^ { 3 } , and the dust production rate is about of 0.015 Solar mass per year for whole the Galaxy .
