Astronomy is a field of science that studies the nature and motions of celestial bodies. This includes studying objects such as stars, planets and entire galaxies.
The pursuit and study of astronomy as a science can be difficult at times, but the degree of difficulty is subjective to different individuals. Advancing through astronomical studies leads to questions and problems of greater difficulty.
Math is used in astronomy to calculate routes for satellites, rockets and space probes. In addition, math is used in the global positioning system, for transmitting messages when data is compressed, and for coding the images and element modeling to build spacecraft.
People have practiced the science of astronomy since ancient times and the discipline has no formal inventor. Knowledge of astronomy stretches back prior to recorded history, as evidenced by such ruins as henge circles, sky disks, moon calendars and sun dials.
Most astronomers are employed by universities and colleges either directly or by association through a laboratory or observatory. Other career options include federally funded research laboratories, private businesses and the public industry.
Astronomy is a branch of science that studies objects outside the atmosphere of Earth, and the motions and nature of these objects. According to the e-Science Portal for New England Librarians, the two main branches of astronomy are optical and non-optical.
Some good sources for astronomy news include ScienceDaily and Space.com. As of 2015, both of these websites offer recent articles concerning space and astronomy to read for free.
According to teach-nology.com, geometry is used in astronomy to determine the properties of stars and other objects in space. It is developed to be a practical guide in measuring the velocity, area, volume and length of heavenly bodies. Astronomy is the study of these objects, and geometry assists i
Trigonometry is used to measure the distance to stars in the solar system, and the motion of nearby stars compared to more distant stars. The method of measuring distance in space is called trigonometric parallax.
Radio telescopes are important in astronomy because optical telescopes can only observe objects that emit or reflect light. As light comprises only a narrow range of the electromagnetic spectrum, radio telescopes have played a vital role in obtaining knowledge of the universe.
