What is Astronomy?
Astronomy is a natural science that deals with the study of celestial objects (such as stars, planets, comets, nebulae, star clusters and galaxies) and phenomena that originate outside the atmosphere of Earth (such as cosmic background radiation). It is concerned with the evolution, physics, chemistry, meteorology, and motion of celestial objects, as well as the formation and development of the universe (http://en.wikipedia.org/wiki/Astronomy).
Astronomy is one of the oldest sciences. Prehistoric cultures left behind astronomical artifacts such as the Egyptian monuments, Nubian monuments and Stonehenge, and early civilizations such as the Babylonians, Greeks, Chinese, Indians, Iranians and Maya performed methodical observations of the night sky. However, the invention of the telescope was required before astronomy was able to develop into a modern science. Historically, astronomy has included disciplines as diverse as astrometry, celestial navigation, observational astronomy, the making of calendars, and astrology, but professional astronomy is nowadays often considered to be synonymous with astrophysics (http://en.wikipedia.org/wiki/Astronomy).
What is Astonomy doing for Modren Technology?
According to Astronomy Magazine Vol. 40 no. 5 May 2012 issue, Astronomy has done many things for Technology, including:
- Developed wireless internet. John O’ Sullivan developed this signal for evaporating black holes. This signal is now used as the wireless internet system.
- GPS (Global Positioning System) comes from 24 of the 30 satellites being used for the general public.
- The James Webb Space Telescope (JWST) which is scheduled to launch 2018 is also used for optical mapping in technology.
- The study of the Sun’s Chemical composition is used for cancer treatment, X-ray and gold nanoparticle.
