    A black hole has appeared on the Sun: a plasma stream will go to the Earth at a speed of 2.9 million km/h

    In the coming days, a huge stream will fall on the Earth solar particles in the form of solar wind, which will cause a geomagnetic storm.

    A huge black hole has appeared on the Sun, which is located in the very center of our star. Scientists believe that already on December 1 or 2, a stream of solar wind will break out of this hole, which will cause a geomagnetic storm on the planet, writes Live Science.

    The black spot on the Sun that has recently appeared is a coronal hole. Such holes are regions in the Sun's upper atmosphere where the plasma is not as hot and dense as the surrounding regions, so they appear black.

    Due to changes in the position of the magnetic field lines around these coronal holes, the Sun throws huge streams of plasma into space, which sometimes rush towards the Earth in the form of a solar wind. This stream of solar particles should escape from this hole already on December 1 or 2 and fly to the Earth at a speed of 2.9 million km/h. As a result, in about a day it will reach the planet.

    Basically, such a stream of solar particles absorbs our magnetic field, but as a result of a collision with it, geomagnetic storms arise on Earth. Some particles break through the Earth's magnetosphere near the poles, where it is thinner, and penetrate into the upper atmosphere. There, they interact with oxygen and nitrogen molecules, releasing energy in the form of light and creating beautiful auroras.

    According to scientists, the geomagnetic storm that may occur in the first days of December will not be very strong. However, it can cause slight fluctuations in the power grid and interfere with some functions of satellites, including GPS systems.

    Stronger geomagnetic storms can have much more serious consequences. They can not only deform the Earth's magnetic field so much that even satellites can begin to fall on the planet, but also disrupt all power systems and even disable the Internet.

    Such geomagnetic storms on Earth also cause solar flares and coronal mass ejections, which are also huge streams of plasma being carried away into space. According to NASA, some ejecta from the Sun can reach Earth in 15 hours, but especially strong eruptions on our star result in streams of particles that travel at the speed of light and reach Earth in 8 minutes.

    Scientists are still trying to understand the exact nature of eruptions on the Sun and what happens on our star during its increase in activity . By the way, such an increase in the activity of the Sun is already gradually beginning, because the star enters the stage of its maximum activity during the 11-year solar cycle.

    As Focus already wrote, China built the largest in the world's solar telescope, which consists of 313 dishes, and it is designed to study solar activity and predict the occurrence of geomagnetic storms.
