Disturbing news has been published in recent days after it was reported that a sunspot, a region of the Sun with a relatively low temperature in the king of stars, has increased ten times in size and is moving towards the Earth. That is why in this note we will tell you what is known about it, as well as other important information that you should know about this phenomenon.
The sun’s spot increases 10 times in size and goes toward the Earth
According to the original Live Science report, if sunspots It will continue to grow very rapidly in the coming days and will produce very intense flashes that will rush towards our planet. The effect of this energy release would jeopardize the satellites and communications systems of the world’s space agencies.
However, the agency itself indicated that this phenomenon does not currently represent a real danger to our planet.
What he mentioned is that the Sun’s activity has changed significantly in recent years and has led to the outbreak of Category X eruptions that have erupted on Earth since the spring of 2022. The number of such phenomena is likely to increase. Over time as we approached the next solar maximum.
What is the sun spot?
a sunspot It is a region of the Sun that has a lower temperature than its surroundings and has intense magnetic activity. a sunspot It usually consists of a dark central area, called the ‘umbra’, surrounded by a lighter ‘semi-shadow’. A single spot can measure up to 12,000 km (roughly the size of Earth’s diameter), but a group of tinctures It can reach 120,000 km in extension and sometimes more.
The semi-shade consists of a structure of light and dark threads that extend more or less radially from the shadow. Both (shadow and semi-shadow) appear dark in contrast to the photosphere, simply because they are colder than the average temperature of the photosphere; So the shadow temperature is 4000 K, while the semi-shade temperature is 5600 K, obviously less than the ~6000 K that the photospheric grains have.
Under Stefan-Boltzmann’s law, where the total energy radiated by a black body (such as a star) is proportional to the fourth power of its effective temperature, the shadow emits approximately 32% of the light emitted from an area of equal size.. the photosphere Likewise a semi-shadow has a brightness 71% of the photosphere.
dark sunspot It’s just a contrast effect; If we could see a spot of sorts, with an Earth-sized shadow, isolated and at the same distance as the sun, it would be about 50 times brighter than a full moon. The tinctures They are relatively immobile with respect to the photosphere and participate in the solar rotation. The area covered by the surface of the sun tinctures It is measured in terms of one millionth of the visible solar hemisphere.
