But what is like a sponge scrub Daddy, it is not as cute as it appears. For us here on Earth, it could produce a solar emoji a beautiful dawn sight — or it could mean problems for the planet’s telecommunications systems.

The sun is essentially “the largest nuclear reactor in our solar world,” he said Brian Keatingprofessor of physics at the University of California at San Diego. A flurry of activity occurs every second in a mass, a mass, a ball of hot steam – from the conversion of hydrogen into helium, which has as much heat as some nuclear bombs, in electrical storms and the movements of the sun.
Some of that solar activity was photographed on Wednesday by a NASA satellite, Keating told The Washington Post.
In the image, a trio of uneven patches that make up the “face” — which cannot be seen by the human eye because they are in the ultraviolet spectrum — are known as coronal holes, or slightly cooler sections in the sun’s stratum. which usually has a temperature of about 10,000 degrees Fahrenheit.
“We’re talking about a few hundred steps, so it’s not like some skis,” Keating said. “But because they are so dark and because we see them in the ultraviolet rays, which the naked eye cannot see,” [NASA satellite] he sees them in the dark holes.

Not only coronal holes interesting figures revolving around the surface of the sun. Areas of high magnetic field activity are constantly sending the solar wind – or the flow of protons, electrons and other particles – into the universe.
“More than just a face, its eyes are like laser beams shooting bright particles that can cause serious disturbances to the atmosphere on Earth,” said Keating.
When particles that carry an electric charge hit the planet minute by minute doses, colorful dawns, could follow, inducing brilliant displays from the vapors of the air interacting with the energy packs of the sun. The problems come if a large number of teeny-ear particles hit Earth, Keating said. Instead of being cut into the Earth’s magnetic field, radio antennas could pick up and transmit radio, television and other means of communication. Severe solar storms can also damage electrical grids and cause power outages, Keating added.
while Photos of the smiling sun have been taken before – for example, in 2013 after it ate a “comet” or in 2014 when NASA called it the “Cucumber Sun” – the worst case scenario described by Keating did not happen for almost two centuries. . The most recent violent geomagnetic storm to affect Earth was the 1859 Carrington Event, which caused fires at several telegraph stations as auroras appeared in tropical regions.
Until it was time, he said.
“Scientists expect that to happen on average, probably two percent, every year, and all these magnetic bullets have been fired for so long,” Keating said. “Yes, it can be really scary, and the consequences can be much more dramatic, especially in our technology-dependent society today.”
The sun’s particles from the most recent laughter events can reach the Earth at the time of the night of the ghost year.
“There might be something on our way for Halloween night for everyone,” Keating said. “Pretty spooky, but hopefully not too spooky.”
The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center has issued a Saturday watch for a minor geomagnetic storm, warning that conditions could change from “unsettled” to “active.” Flare ups of coronal holes are expected to continue through Wednesday.
