Dark Universe

Modern observations show that dark matter and dark energy make up 95% of the energy in the Universe. Despite the extensive effort, the dark sector's constituents, characteristics, and origins have remained obscure. The aim is to study the consequences of the interacting dark sector, considering both classical and unconventional models of new physics.

Astrophysics of an accelerating Universe

How fast is the Universe expanding? What is dark energy? What is dark matter? The international project J-PAS (Javalambre Physics of the Accelerating Universe Astrophysical Survey), helps to answer these basic questions of observational cosmology. The observations will be carried out with a telescope built for this project in Spain.

4MOST observation

The telescope 4MOST enables us to obtain valuable information about the Milky Way's chemical and dynamical composition. This data is crucial for learning the history of our home galaxy. In addition, the 4MOST telescope maps a large part of the universe in the southern sky and at the same time collects information about the evolution of galaxies. Tartu Observatory researchers are involved in the planning and developing the observation strategy.
