Sun It is one of those essential elements of life that we often do not think about until the heat bothers us or we need it for some task. In fact, when we look at the sky we only see the yellow or red stain of the light that reaches us, and we do not think about what that celestial body in the center of our body actually looks like. galaxy. It is an essential part of life and without it our history would not be being written. Now, as a way to show us a little more about what the Sun looks like sitting in its space, the NASA has released an incredible video timelapse that portrays the last 10 years of solar activity.
Of course, many of the reasons we don’t see the sun as much are because of the damage that can be done to the eyes if done long-term, so experts had to find ways to be able to observe it without the need for the retina. One of those is the Solar Dynamics Observatory (SDO) NASA, a project whose mission has been to observe the sun since 2010, which is part of the program Living With a Star (LWS, Living with a star).
The purpose of the LWS program is to “develop the scientific knowledge necessary to understand the aspects of the system connected between the Sun and the Earth and how it affects society ”. It also seeks to study the solar atmosphere and the impact on nearby bodies, in addition to trying to understand how the body’s magnetic field is generated and how it makes other planets float in its orbit.

He SDO has instruments that allow you to capture images of the Sun every 12 seconds with 10 different wavelengths of light. In this way, this video could be created.
The images that we can see in the video are from the Sun’s corona, which is its most visible atmospheric layer that, according to NASA, was captured at the wavelength of 17.1 nanometers. What we see are all the images that the project captured over 10 years.
The NASA explains that in one part of the video you cannot see the light because the Earth or the Moon they passed the SDO and behind the Sun preventing the photographs from being taken, in addition to the fact that in 2016 there was an error that caused the imaging to stop, but it was resolved in a week.
The video is quite impressive and shows the Sun as we have never seen it before. At some points the energy of the light that comes out of it can be appreciated and it seems that it is focused on only one side. With just over an hour in duration, it is remarkable how the body does seem to have changes over time although they seem minimal, which will serve as a reason for analysis for the experts and thus achieve a better understanding of the celestial body.
More than 400 years have passed since Galileo Galilei He made a description of the sunspots, which he observed with the naked eye, in addition to stating that both the sky and the Sol they were “corruptible”, that is, they were neither eternal nor static.
Sun it is described as an almost perfect sphere of fiery plasma whose internal movement creates a magnetic field under which the rest of the planets rotate. Its diameter is around 1.39 million km, 109 times larger than Earth. It is believed to have been around for 4.6 billion years, and that one day its light could be extinguished like any other star.
