What Is an Astronomical Observatory?

An observatory is a location for observing marine, terrestrial and celestial events. Some disciplines around observatories include climatology, meteorology, volcanology, oceanography, and geophysical. Modern observatories have different specifications depending on their purpose. There are many things to consider in an astronomical observatory, especially when astronomers have to view parts of the electromagnetic spectrum. This breakdown looks into an astronomical observatory and its applications.

Astronomical Observatory

An astronomical observatory is any structure with telescopes and auxiliary instruments for observing celestial objects. The classification of such observatories depends on the section of the electromagnetic spectrum they have to observe. Technically, most observatories are optical in that they are designed to observe near and in the region where the spectrum is visible to the human eye. Some observatories can detect radio wave cosmic emitters, while satellite observatories have special telescopes to study celestial energy radiation sources.

Types of Astronomical Observatories

Space-based Observatories

Space-based observatories are instruments found in outer space, with many orbiting the earth. Space telescopes observe astronomical objects at electromagnetic spectrum wavelengths that cannot penetrate the earth’s atmosphere. The earth’s atmosphere is opaque to X-rays, gamma rays, and ultraviolet radiation. Therefore, observation within these parts of the electromagnetic spectrum should be done above the earth’s atmosphere.

Ground-based observatories

Ground-based observatories are on the earth’s surface and are great for observing radio and visible light partitions of the electromagnetic spectrum. These optical telescopes are found inside a dome to protect delicate instruments against elements. For example, telescope domes have an opening on the roof that allows observation and can be closed when out of service. In addition, the upper part of the astronomical observatory can rotate to allow observation of various sections of the sky.

Airborne Observatories

Airborne observatories have a better vertical reach than ground-based observatories. This puts them above a larger portion of the earth’s atmosphere. They may also offer advantages over space telescopes because they are deployable, repairable, and updatable at low costs.

Location of Observatories

Ground-based observatories are found in conducive conditions for observations. These optical telescopes should be placed away from cities with significant populations. Being far from major population centers helps avoid light population, smog, and other factors affecting visibility.

The best location for modern observatories should have dark skies with more clear nights every year. Dry air and high elevations are preferable because the earth’s atmosphere is thinner, therefore minimizing atmospheric turbulence effects for better astronomical seeing.

Good weather should also be considered because cloud cover may inhibit data collection. The astronomical observatory can have various equipment like programmable telescopes for researchers to train specific targets for observation collection. These telescopes can also launch balloons for gathering additional material.

Resolution and Detail of Astronomical Observatories

Astronomical observatories have varying resolution and detail levels that observers can make. Technical specifications and data are accessible to individuals willing to schedule telescope time to understand the availability and whether their needs will be met. It is also crucial to request a slot with the organization’s sponsorship. The astronomical observatory can also maintain a database of scheduled activities, observations, and other matters.

The inner workings of an astronomical observatory are complex, and some technicalities are involved. These observatories must be operated by only certified engineers, opticians, electricians, and computer scientists. This team ensures the astronomers have all the necessary tools for observation.
