Spaceweather.com according to, shortwave radio blackouts disrupted communications between ham radio operators and mariners. In the last year and a half, the activities in the Sun have increased. The American space agency NASA says that the Sun is going through its 11-year cycle and is in a very active phase. Because of this, explosions will continue to happen in the Sun till 2025.
A new solar cycle begins every 11 years. During this the Sun becomes very active. There are explosions in it. During this, coronal mass ejections and solar flares are emitted from the Sun. If their direction is towards the Earth, then geomagnetic storms occur on our planet, which can affect the satellites and the power grid on the Earth. The incident that happened on Sunday could also be the result of this.
NASA’s Solar Dynamics Observatory (SDO) monitors these events and alerts us. On the other hand, talk about solar flares, when the magnetic energy of the Sun is released, solar flares are formed from the light and particles coming out of it. These flares are the most powerful explosions ever observed in our solar system, releasing energy comparable to billions of hydrogen bombs.
what is sunspot
A sunspot is a dark region on the Sun that is visible on the Sun due to its magnetism. Sunspots can last from a few hours to a few months. Not all sunspots cause solar flares, but when they do, their effects can be felt on Earth. Apart from this, the Sun itself also releases a lot of flares into space.
