An active region on the sun — an area of intense and complex magnetic fields — has come to the attention of the scientific community. Between July 5-11, 2017 the NASA’s Solar Dynamics Observatory captured a video of a black sunspot on the surface of our star and it seems to be growing rather quickly. The core is bigger than our planet Earth and it’s said there may be probabilities of damages to our satellites and therefore to our communication system (even if NASA’s Solar Dynamics Observatory said it’s “too early to predict”).
Why may we experience some communication blackouts?
Occasionally sunspots can release solar flares and eject clouds of solar material, accompanied by blasts of charged particles. While people are protected by Earth’s magnetic field, technology may suffer some disruption.
Is this an exceptional event that announces the “Armageddon”?
Not necessarily. Such sunspots are actually a common occurrence on the sun, but are less frequent as we head toward solar minimum, which is the period of low solar activity during its regular cycle.
For those who don’t know anything about the Solar Cycle, approximately every 11 years, the sun undergoes a complete personality change from quiet and calm to violently active.
During the solar maximum, the height of the sun’s activity, we cab record numerous sunspots, punctuated with profound eruptions that send radiation and solar particles out into the far reaches of space.
Well, the sun was spotless for two days until NASA recorded this black spot zone, appearing like freckles on the face of the sun, but it’s the only group at this moment.
You can judge by yourself by watching their official video:
