What is the job description of an astronomer?
Job Description for Astronomer. Astronomy is the science of examining the cosmos and using applied physics and mathematical formulas to attempt to explain, classify, discuss, and offer explanations about the universe. Astronomers use a variety of high-tech, sensitive instruments to measure the location and movements of objects in the sky.

What is the importance of astronomy in our life?
It develops an understanding and description of all forms of energy and matter and can be said to occupy the middle ground between mathematics and engineering. Astronomy is the science that deals with the origin, evolution, composition, distance and motion of all bodies and scattered matter in the universe.

What are the main features of early astronomy?
Most early astronomy consisted of mapping the positions of the stars and planets, a science now referred to as astrometry. From these observations, early ideas about the motions of the planets were formed, and the nature of the Sun, Moon and the Earth in the Universe were explored philosophically.
astronomy zenith
What is the zenith of the sky?
The zenith is the point in the sky vertically straight above the observer. It is the point where the observer’s sight-line is perpendicular to the Earth’s atmosphere, and hence where the smallest amount of air – termed the airmass – lies along it.
What is the zenith and why is it important?
The zenith is the point in the sky vertically straight above the observer. It is the point where the observer’s sight-line is perpendicular to the Earth’s atmosphere, and hence where the smallest amount of air – termed the airmass – lies along it. For this reason, objects close to the zenith are subject to less atmospheric distortion…
What is the zenith angle of the Sun?
The zenith angle θz (also called the zenith distance) is the angle between the local zenith and the line joining the observer and the sun. It is an angle between 0° and 90°. The solar altitude α (also called the solar elevation) is the sun’s angular height above the observer’s celestial horizon.
Why is the zenith the best place to view the stars?
For this reason, objects close to the zenith are subject to less atmospheric distortion than those anywhere else on the sky, and astronomers usually try to observe objects when they are as high in the sky as possible. Specifically, an object makes its closest approach to the zenith at the moment when it culminates .
astronomy z
What is Z in astronomy?
In astronomy, it is customary to refer to this change using a dimensionless quantity called z. If λ represents wavelength and f represents frequency (note, λf = c where c is the speed of light ), then z is defined by the equations:
astronomy zero point
What is a zero point in photometry?
Zero Point (photometry) In astronomy, the Zero Point in a photometric system is defined as the magnitude of an object that produces 1 count per second on the detector. The zero point is used to calibrate a system to the standard magnitude system, as the flux detected from stars will vary from detector to detector.
