The big bang- how the universe began

Question 1 a) infr ared light astronomy Infrared Astronomy is a study of the Infrared Radiations emitted from aerial objects. All objects from trees, buildings on the earth to distant galaxies emit infrared radiation. The cosmic remains particles block the view of the telescopic instauration such as the center of the Milky Way just these cosmic circulate particles are transparent in the Infrared Radiation wavelengths. It is ripe intacty signifi tooshiet for studying asteroids, comets, planetary satellites and interstellar dust clouds where stars are forming. as well because of the expansion of the foundation which shifts dexterity to pineer wavelengths, most of the visible radiations emitted by stars and galaxies during early stages of the formation of the universe are this instant shifted to Infrared Radiation wavelength range. b) intercommunicate Waves radio set waves spend a penny the longest wavelengths in the electromagnetic spectrum. intercommunicate wave s can be either very long or very short. wireless waves are extremely useful because they can go finished the earths atmosphere. Radio waves are produced by charged particles pathetic venture and forth. Objects in space, such as planets and comets, giant clouds of shoot a line and dust, and stars and galaxies, emit light at many unlike wavelengths. well-nigh of the light they emit has very large wavelengths. These long waves are in the radio region of the electromagnetic spectrum.

Radio telescopes put together and focus the radio waves from an object in space; the omen then returns to earth in profuse deta il dig astronomers valuable information abo! ut the planet or star. Radio astronomy has the advantage that sunlight, clouds, and rain do not regard observations. Question 2 Due to the detail that 75% of the universe is filled with Hydrogen and 25% is helium it is showing that there was a stage when the universe was the right density and temperature to create these since...
