The sun is so far from Earth that its light takes eight minutes to reach the surface of our planet. Despite the distance, its magnetic field is having is having on our world is a huge influence. For example, a strong electromagnetic pulse can cause the light on the whole continent, so scientists it is extremely important to know the power of the magnetic field. Unfortunately, to obtain accurate data, they have not yet succeeded, but researchers from Queen’s University in Belfast claim to have done it.
To obtain an accurate measurement of the magnetic field scientists interfered with the Earth’s atmosphere — it weakens the field lines, so its capacity may be much higher than previously thought. The researchers claim that they received accurate data due to the good for the circumstances — they turned his telescope to the area of the surface of the Sun, which is considered the most volatile.
We have very few measurements of force and spatial characteristics of the magnetic field of the Sun. It’s a bit like trying to study the Earth’s climate, not being able to measure the temperature in different geographical locations.

During the ten-day observation they recorded a powerful flash — analysis of its structure showed that the strength of the solar magnetic field 10 times greater than previously thought. If so, then the opening really means a lot. The magnetic field of the Sun determines the boundaries of the Solar system and protects us from cosmic rays. It also directly affects the climate of the Earth, and forms the Northern lights, and their changes are able to change the figures of compasses and GPS systems.
Discoveries concerning magnetic fields of the planets are still. In September 2018 the spacecraft “Juno” opened new features in Jupiter’s magnetic field. It turned out that it has a much complex structure — read about it in our material.
