Initially, the galaxies were purely gas objects with the so-called 'primordial' element composition, comprised of H and He (with mass ratio of ~4:1). More...

The study of the optical, physical, and chemical properties of dust from small bodies in the Solar system helps us to understand the main mechanisms of their formation and evolution in the protosolar nebula. More...

Active galactic nuclei (AGN) are unresolvable with modern optical telescopes since the apparent angular size of the central parsec is <<0.1 arcsec even for the closest active galaxies. This leads to difficulties with methods for estimating distances within the AGN. More...
