Astronomy
If you are curious to know about Ultraviolet astronomy, then go through the following article on ultraviolet astronomy.
Astronomy is one of the oldest science. Astronomy is the name of a unique scientific study of celestial objects like stars, planets and galaxies and the atmosphere in space. In early days people used to study motion of celestial objects in space by observing night sky from mountain tops, high buildings and trees. They gradually started studying the movement of sun, moon and stars in the sky and thought that the sun rotates around the earth. Later, Italian scientist Galileo observed the space and solar system through a telescope and proved the idea wrong and clarified that the earth in itself rotates around the sun.
Thus observational or optical astronomy appeared as a new concept. Over the centuries, astronomy has become a very sophisticated scientific study and has become diverse. Observing celestial objects in the sky is no more the only definition of astronomy. With the passage of time scientists have discovered that apart from light and optical radiations, celestial objects emit electromagnetic, infrared and ultraviolet rays also. The wing of astronomy which deals with observations at ultraviolet radiation from objects is known as ultraviolet astronomy.
The main aim of ultraviolet astronomy is to study objects that are within ultraviolet wavelengths ranging between 100 to 3200 A. as light of these wavelengths are absorbed by the atmosphere of the earth, observations of these wavelengths are performed from upper atmosphere or space. With the help of ultraviolet line spectrum measurements, densities, chemical composition and temperature of the interstellar medium and the temperature and composition of young stars can be observed. But apart from that ultraviolet astronomy can also provide information regarding the evolution of galaxies.
Now you can understand why there's a growing interest in Ultraviolet astronomy. When people start looking for more information about Ultraviolet astronomy, you'll be in a position to meet their needs.
