Radioastronomy New Findings

Radio astronomy could also be a subfield of astronomy that studies celestial objects at radio frequencies. The primary detection of radio waves from an astronomical matter was in 1932, when Karl Jansky at Bell Telephone Laboratories detected radiation coming from the Milky Way. The invention of the cosmic microwave background, considered evidence for the massive Bang theory, was made through astronomy. Radio astronomy is conducted using large radio antennas mentioned as radio telescopes, that are either used singularly, or with multiple linked telescopes utilizing the techniques of radio interferometry and aperture synthesis. The employment of interferometry allows astronomy to determine high angular resolution, because the resolution of an interferometer is about by the space between its components, rather than the dimensions of its components. Radio astronomers process the masses of data collected by a telescope. To help add up of the strings of numbers, they convert the numbers into pictures. Each number represents information from a specific point in space. Often they have colours assigned to the numbers corresponding to the amount of information they represent. Astronomers then combine the colours to make a picture, visualising the information to reveal some of the characteristics of objects in the Universe.
