What is an observatory primarily used for?

An observatory is primarily used for viewing astronomical objects and phenomena, such as stars, planets, and other celestial bodies. This facility is equipped with powerful telescopes and other instruments that allow scientists and astronomers to observe the universe in detail. The primary mission of an observatory is to gather data about the cosmos, enabling researchers to make discoveries and enhance our understanding of celestial mechanics, astrophysics, and cosmology.

In contrast, the other options represent different functions. A laboratory for chemical reactions focuses on conducting experiments in chemistry rather than astronomical observations. A weather observation station is dedicated to monitoring and recording atmospheric conditions, which is not the primary aim of an observatory. Lastly, a venue for scientific conferences serves as a space for academic discussions and presentations rather than facilitating direct observation of physical phenomena.
