<u />
Explanation:
The most important electromagnetic radiation is the one that comes from the Sun. <em>It is the one that we can measure more accurately</em>. It is very important to have detectors to be able to deepen the knowledge of the Sun <em>and the surrounding atmosphere and how they influence the environment in which they are immersed.
</em>
<em>Within the electromagnetic radiation is the</em> "<u>Cosmic microwave background</u>", <em>a background of light in the spectrum from which it comes from all directions, has a very low energy, has no impact on everyday life. </em>Today it is known that it is a reflection of how the Universe was born, what happened after the Big Bang, which started in a very hot spot and expanded very quickly, gradually cooling.
