If 휶 is the angle subtended at the unaided eye by the distance object and 휶? Each chemical element has its own "signature" spectral pattern, so it's possible to analyze the composition of a star from many thousands of light-years away provided astronomers can collect its light. The radio telescope is an instrument that is used in astronomy to study radio lights that naturally occur from the stars, galaxies, or other astronomical objects in space. The Hale Telescope is used every night for astronomical research thanks to a modern and evolving instrument suite. Astronomical Instruments . Specialized light meters (called photometers) help them measure the varying stellar brightnesses. Describe the physical and chemical nature of stars, and especially our sun, and apply the astronomical techniques used to measure stellar properties.

Astronomical observatories are structures containing telescopes and auxiliary instruments with which to observe celestial objects. They sense the light they are sensitive to and send the collected data to a computer which then decodes it into arbitrary colors that we can see. Astronomical Instruments used by Maharaja Sawai Jai Singh Hindu astronomy received a lot of encouragement from the Maharaja Sawai Jai Singh of Jaipur who introduced new lot of instruments to calculate the movement of stars, planet, and their effect on time and other social life.
