On the Easter weekend, when people were heading out to soak up some sun as spring approached, the sun erupted in a spectacular volcanic eruption. according to Interesting geometrythe explosion rated X1.1 on the NASA Solar Storm Rating Scale, placing it in the strongest category of solar flares by NASA.
A few days later, another explosion on the Sun was even more powerful, earning a rating of X2.2 on the NASA scale. Sunbursts are rising.
When the sun explodes
As we head into summer, the good news for beachgoers—not to mention life on Earth—is that these solar flares pose no immediate threat to human life or other life. A sunburst won’t make you a worse sunburn.
What it can do is disrupt radio communications and hit orbiting satellites. A similar eruption occurred earlier this year, interesting engineering suggests, shrinking more than 40 satellites right after they were launched into orbit.
as such Live Science He explains that the general term for solar flares or explosive eruptions on the Sun is “solar flares,” and they are closely related to sunspots. The basic story here is that huge amounts of energy are constantly being produced by nuclear fusion in the core of the Sun. This energy gradually works its way outward until it reaches the visible solar surface, where the energy is liberated and flows into space like sunlight.
This energy flow is turbulent—think of a tea kettle that’s bubbling and beeping, and it’s been expanded about a trillion times. The turbulent and extremely hot gas generates strong magnetic fields, which leads to further turbulence.
All this activity is producing (relatively) cooler regions on the Sun’s surface, darker than its surrounding very bright surface, which can be seen from Earth – with proper precautions! – Like sunspots. However, these cooler regions are counterbalanced by the hotter regions nearby, where magnetic fields twist, pick up, and repair. And every time they do, the result is an explosive eruption on the Sun: a solar flare of X-rays and other rays, and a protrusion, or stream of electrically charged gas, thrown into space.
Solar storms and the solar cycle
Dramatic time-lapse footage of the solar prominence shows that most of this glowing material falls on the Sun. But some of them are blasted outward with enough force to overcome even the massive gravitational field of the sun, and are thrown out into space as Coronal mass ejectionor CME.
If it happens to be blown outwards in the right direction, the result in a day or so will be a stream of fast-moving charged particles passing through the Earth. Trapped by Earth’s magnetic field, some will deflect in the upper atmosphere, particularly at polar latitudes, resulting in a beautiful auroral display in the night sky.
Sunspots and their accompanying eruptions tend to rise and fall in numbers and intensity over a cycle of about 11 years, according to interesting geometry, a fact that’s been known for 18 years.The tenth century. The sun is currently rising from 25The tenth A cycle since astronomers started counting: NASA BlogRegularly updated, tracks and reports for each eruption as it is discovered.
Solar storm measurement
The strength of each eruption is measured and reported with a scale similar to the scales used to measure ground storms and earthquakes. A decade ago, during the last solar cycle, NASA Produce a more detailed account of this measurement scale. Less active solar flares are assigned to Class A, with more powerful flares categorized respectively as Class B, C, M and X, being the most powerful class.
As with the Richter scale of seismicity, each class is ten times more active than the layer below it, as measured by the intensity of the X-rays produced by an explosion on the Sun. Thus, categories A, B, C and M are divided into 10 subcategories. Since Class X is the strongest, it is the only class with more than 10 subclasses.
Classes A to C do not have near-ground disrupting effects, while Class M flares can cause minor disturbances to radio signals. Class X flares, which are the most powerful, can lead to more widespread disorders.
The last double eruptions were powerful enough to reach Class X (X1.1 and X2.2), while the most powerful explosion on the Sun recorded with modern technology, in 2003, overloaded the sensors when it hit X28.
It kind of makes you want to go to the beach, put on your shade, put on some sunscreen and have a nice, warm blast in the sun.
