HAM-nomy is a term where HAM and astronomy combines. Astronomy is the study of the moon, sun, stars, planets, comets, gas, galaxies, gas, dust and other non-Earthly bodies. Observing the space by listening to invisible radio waves that are produced by celestial objects is called ham radio astronomy. Continue the reading to get immersed in hamnomy.
The use of radio waves in studying the heavens is more effective than the use of visible light as the radio waves penetrate through earth’s dense atmosphere and interstellar gas and dust. A big advantage of radio astronomy from optical astronomy is that observations can be done on objects or events that are located in the far reaches of the universe.
The optical telescopes collect visible light, bring it to a focus, amplify it and make it available for analysis by various instruments, so do radio telescopes collect weak radio light waves, bring it to a focus, amplify it and make it available for analysis. Radio telescopes come in different shapes and sizes – as large round curved discs like satellite dishes, as frames constructed like fences or as a cluster of small vertical structures.
– Existence of neutron stars, dark matter and extrasolar planets
– Violent universe of quasars and radio galaxies
– Presence of supermassive black holes
– Cosmic microwave radiation from the big bang
– Evolution of quasars and radio galaxies
Several outstanding discoveries have been made in the field of radio astronomy during the last six decades. These have revolutionized our understanding of the mysteries of the Universe. Observations of radio galaxies and quasars that emit extremely powerful radio waves indicate presence of supermassive black holes at their center. in the interstellar medium, over 150 molecules have been discovered giving details about the physics and chemistry of the interstellar space; these are also ingredients of life in the Universe.
