The European Space Agency (ESA) has published an audiovisual representation of the Sun's activity over the past three years.. For this, data from the Solar Orbiter spacecraft was used, writes Space.

One of the main manifestations of solar activity are solar flares.. These are eruptions of energy and radiation that constantly occur on our star, but have different strengths. Solar flares arise as a result of the alignment of magnetic field lines and their appearance is associated with the appearance of sunspots on our star. These are dark areas on the Sun that are made up of cooler plasma..

When sunspots face the Earth, flares can negatively affect our planet, because as a result of such emissions of radiation, radio communications are often lost, and the operation of satellites in low Earth orbit is sometimes disrupted.

In total, scientists divide solar flares into five categories according to their relative power and the strongest are category X flares. Over the past couple of months, there have been many such flares on the Sun, because our star has entered the solar maximum phase. This is the period of greatest solar activity, which will last until about the beginning of next year..

Scientists from ESA took the last 3 years of solar observation data collected by the Solar Orbiter spacecraft and turned it into sound that humans can hear.. At the same time, the voiceover was combined with images of our star and a video was created.

In the video you can see blue circles appearing on the surface of the Sun and a sound associated with each of these circles. The closer we get to 2024, the frequency of blue circles will increase..

To create the video, scientists took images from two Solar Orbiter instruments: STIX (a spectrometry telescope for taking X-ray images) and EUI (an instrument for taking ultraviolet images).. STIX captured the location and size of the X-rays that the flares emit, and they are represented by blue circles. The EUI shows the Sun's outer atmosphere in yellow..

An increase in the frequency and size of solar flares is associated with the approach of solar maximum.

As for the change in scale in the video, when the Sun becomes larger in size, then smaller, this is due to the fact that Solar Orbiter has an elliptical rather than a circular orbit. Every six months, a spacecraft approaches the Sun. Scientists have reflected this approach with the help of a sound that becomes louder.

Focus has already written about the five greatest mysteries of the Universe that confuse scientists. Dark energy, supermassive black holes, dark matter - all this remains largely unclear to astronomers and physicists.

Focus also wrote that at the beginning of January, the first X-category flares of this year arose on the Sun, which negatively affected our planet.
