Strictly speaking, not all professional astronomers are dedicated to "observing" through large telescopes. Some specialize in certain areas where such instruments may not be so necessary (e.g. cosmology), or they take greater advantage of advances in space exploration (e.g. planetary sciences, exobiology). Nevertheless, below are listed different types of astronomical observations carried out by professionals, to give an idea of the many ways to learn more about the Universe.
Optical astronomy
Astronomical observatories are constructions dedicated to the observation and study of celestial objects. They are the most characteristic expression of professional astronomy, allowing distant objects to be observed in detail and from there obtaining many other data of enormous scientific value. Currently there are many types of observatories, depending on the type of astronomical discipline used. The big ones optical observatories They explore space in a small area of the electromagnetic spectrum, most of which is perceptible to the human eye (the visible range).
Currently there are professional observatories in many countries around the world, but for an obvious reason, the organizations and consortia that manage these gigantic scientists carefully choose the sites for their location, since they are required to have excellent atmospheric conditions and clear skies to get the most out of them. get the most out of powerful instruments. Traditional observatories are characterized by being located on the Earth's surface, with optical telescopes that collect starlight using mirrors, just as the well-known amateur reflector and catadioptric telescopes do. As many fans also know, Chile is a country known for having one of the clearest skies in the world, which is why many large observatories have been located in this territory.
