The Department of Solar Physics and Astronomy has been created since 1942 as the Department of Solar Physics at the University of Tehran's Geophysics Institute, and has been expanded with the extension of the term astronomy. This section has been created to increase the scope of research in various astronomical, solar, and solar-terrestrial fields. The telescope was purchased in 1342 and the solar observatory (1347-1384) was a subsidiary of this section. The building was built at the expense of the late doctor Hussein Keshi Afsharz, founder of the Institute of Geophysics, and his wife's wife, Azizma, on the site of the Institute (Current Wisdom Highway ) Was made. The calculation of the Wolf coefficient and the study of solar activity have been among the activities of this observatory.

Goals and goals:
The study, study and understanding of the sun, horseradish, and planetary environments as a related system is one of the major research objectives of the Sun and Space. On the other hand, the emergence of their supercomputers has helped them solve the hidden secrets of the sun and promising advances in space research.
Where space and solar physics and astronomy focus on:
The Sun's Atmosphere - Solar Winds - Toroidal Flames - Solar Electromagnetic Radiations, including Alphon Waves
Sephardum ion and Plasma Sepehrzmine - The interactions of the Earth's sun
Space Plasma - Magnetic Links
Polar Radiation - Magnetic Storm - Space Climate - Cosmic Radiation
Planets - Magnetosphere - The interaction of the sun - Comets
Astrophysical plasma including absorbent discs
On some days, sunspots are not visible, and in a few days many of them can be seen.
Data on the number of solar spots in about 400 years
Some of the major research priorities:
Understand connective or magnetic bonding
Magnetic resonance bonding or transplantation is a change in the field of magnetic field configuration that releases the magnetic energy stored in the plasma.
What are the basic physical and pathological processes of magnetic reconnection?
How do the plasma and particles become pregnant and hot?
How is energy and energy transmitted from the Horsphere to the magnetosphere of the planet?
Knowing the interactions of ions - neutral particles that make the ion of the spheric with the atmosphere above the planet pair or coupling.
There are many places in the solar system where the interactions between the particle and the gland are very effective on the behavior of the system. The result of these collisions is the transfer of energy and momentum between their sets. When charged and neutral particles exist in the presence of a magnetic field, the magnetic mobility of the plasma moves inwards, and the inter-plasma and neutral gas forces produce complex electrodynamic interactions. Such interactions have a detrimental effect on the spatial distribution of plasma, and the result is instability.
What are the laws governing the coupling of neutral and ionized particles?
How do magnetosphere and ion systems interact with each other?
How is the interaction between the heliosphere and the interstellar medium?
