fountains of plasma rain might explain one of the biggest mysteries of the sun - all in one solar led street light

fountains of plasma rain might explain one of the biggest mysteries of the sun  -  all in one solar led street light
Today's solar weather forecast requires a maximum temperature of 10,000 degrees Fahrenheit. (
5500 degrees Celsius)
Continuous supersonic wind, mysterious lava eruption-lamp-
And, oh, yes, light rain.
So, you know, take an umbrella.
Although it sounds strange, rain is a common phenomenon in the sun.
Unlike rain on Earth, where liquid water evaporates, condenses into clouds and then falls in droplets of water when it is heavy enough, solar rain is the result of rapid plasma heating and cooling. (
Electrically charged gas that makes up the sun.
Scientists expect to see hot plasma rainrings rise and fall along the sun's giant ring magnetic field, which heats plasma on the sun's surface from thousands of degrees Fahrenheit to nearly two million degrees Fahrenheit. (1. 1 million C).
Now, however, NASA scientists believe that they have discovered a completely new structure on the sun that could be created for many days. -
Even if there is no intense solar flare heat, there will be long rainstorms. [

In a new study published April 5 in the Astrophysical Journal Letters, NASA's team described the structure as zero rainfall. -
Point Topology(RNPTs)—
Super bright, relatively small magnetic rings up to 30,000 miles(
50000 km)
Above the surface of the sun.
Five months of solar observations at NASA's Solar Dynamics Observatory(SDO)
The team detected three clearly visible RNPT structures, each burned for several days at a time by the plasma rain.
"These structures are easily identified and the frequency of rainfall over all observation periods strongly supports the conclusion that this is a common phenomenon," the authors write in their study.
To find melting rain, NASA researcher Emily Mason was surprised by the discovery of these drizzle structures. She was searching SDO videos for signs of rain in a giant structure called the Helmet Ribbon. -1 million-mile-tall (1. 6 million km)
A magnetic ring named after a knight's pointed headdress.
During an eclipse, these ribbons clearly jump out of the corona or the outermost layer of the atmosphere, which seems to be a good place to look for rain from the sun, the researchers wrote.
However, Mason could not find any trace of plasma decline in any SDO towline video.
What she saw was many bright, low, mysterious structures that she and her team later identified as RNTPS.
Relatively low structural height may be the most interesting aspect of the results, the researchers wrote.
Maximum 30,000 miles(50,000 km)
On the surface of the sun, RNTPS is only 2% of the height of the helmet ribbon observed by Mason and her team.
This means that whatever process causes the plasma to warm up and rise along the magnetic line, it occurs in a much narrower region of the solar atmosphere than previously thought.
This means that the process of driving these ubiquitous fountains may help explain one of the mysteries of the sun's eternity. -
Why is the sun's atmosphere nearly 300 times warmer than its surface temperature?
"We still don't know what is heating the corona, but we know it has to happen in this layer," Mason said in a statement.
It was first published in the Journal Living Science.
