Image Processing of Big Data

Discussing computers, computers are of course used to reconstruct the images recorded by observatories, whether terrestrial or orbital, space probes as well as to build images from the radio signals picked up by radio telescopes. A space telescope has a sensor consisting of a CCD camera (Charge Transfer Device) cooled near absolute zero to reduce …

Astronautics

Astronautics covers an extremely wide range of scientific and technical studies, from the chemistry of propellant mixtures (pergols), the study of materials and fluid mechanics to experiments in space biology, physics and physics. astronomy without ignoring the disciplines developed above. Multi-disciplinary, astronautics represents a whole of great interest by the discoveries it entails in our …

Radioastronomy

It has been known since the discovery of Heinrich Hertz in 1887 that radio waves are of the same nature as light waves. In particular they propagate in a vacuum in a straight line (geodesic) at a constant speed of 299792.45 km / s. It is by their wavelength (or their frequency) that the hertzian …
