Stellar physics
The stars are the main building blocks of the visible universe. The stars act as thermonuclear reactors in which all chemical elements heavier than hydrogen and helium are synthesized.
The astronomers of the Tartu Observatory study different types of stars, both observationally and theoretically.

Astronomy seminar
Current shortcomings in our understanding of dark matter distribution in our Galaxy and ongoing strategies for using the Milky Way to investigate the particle physics model for DM are discussed.
Register until 20 September for stellar spectroscopy workshop
We are excited to announce the upcoming stellar spectroscopy workshop hosted by Tartu Observatory under the EXOHOST project, and we invite you to join us on 27–28 September in Tõravere or Zoom.
Astronomy seminar
The cosmic web is vital for studying dark matter and the cosmological model and understanding galaxy evolution. However, detecting the cosmic web from observations is a complex task.
