Mission Goals

“Millimetron” observatory main goal is to study various astronomical objects in our Universe in a wide range of wavelengths – from far infrared up to millimeter. Space telescope unique capabilities will allow revealing new horizons in modern astronomy and astrophysics. With “Millimetron” observatory it would be possible to solve a number of unique scientific problems:

  • How does the chemical evolution of the Universe happen?

    Stars during its evolution form chemical elements and their compounds which are the basis of life, the material for planet formation, change the properties of interstellar gas and affect the new stars formation. Thus, the study of chemical elements distribution in space carries important information about all the evolutionary processes in galaxies and in the Universe. Despite the best efforts of modern observational astronomy, we are still stand far from a complete understanding of these processes. This is largely due to the fact that much of the important information we lost on its way to us due to poor transparency of the space environment in the visible range, which is caused by the presence of large amounts of dust, which is a product of thermonuclear reactions taking place in stars. One way to overcome this fundamental difficulty is the transition of the observations to the infrared region of electromagnetic spectrum, where the dust is not an obstacle, and the transparency increases. Another difficulty lies in the fact that carrying out ground observations in the IR range is difficult due to the atmosphere opacity in this wavelength range except for some areas, which are called windows of transparency. Space Observatory “Millimetron” should expand significantly the possibility of such observations in this wavelength range due to the high sensitivity and a complete lack of atmosphere influence.

  • How does the black hole event horizon vicinity look like?

    Black holes itself do not emit radiation, but accreting on black holes matter emits in all ranges of electromagnetic spectrum. Due to the transparency of the black hole surrounding environment in the short radio waves, observing it in millimeter and sub-millimeter ranges will allow to look as close to the event horizon as possible – to look at this surface which the light is no longer able to leave. “Millimetron” observatory in conjunction with ground-based radio telescopes, using radio interferometry technique will be able to carry out these observations with high angular resolution, which is essential in the study of the condition of compact objects like black holes.

  • How the Universe form and what is the Dark Energy that was found?

    Cosmic microwave background (CMB) – the main source of information about the earliest stages the Universe life. “Millimetron” observatory will be able to carry out research of spatial and spectral irregularities of CMB with an accuracy that was previously unavailable, which will allow to test various models of the Universe inflation (short superfast expansion stage) at the beginning of its existence, as well as to clarify the model of dark energy.
