“It doesn’t just come from everywhere in a coronal hole, it’s substructured within coronal holes to these supergranulation cells. “The big conclusion is that it’s magnetic reconnection within these funnel structures that’s providing the energy source of the fast solar wind,” Bale said. Parker Solar Probe detected highly energetic particles traveling between 10 and 100 times faster than the solar wind, leading the researchers to believe that the fast solar wind is created by the reconnection of magnetic fields. And the spatial separation of those little drains, those funnels, is what we’re seeing now with solar probe data.” It’s kind of a scoop of magnetic field going down into a drain. The magnetic field becomes very intensified there because it’s just jammed. “Where these supergranulation cells meet and go downward, they drag the magnetic field in their path into this downward kind of funnel. Bale, a professor of physics at the University of California, Berkeley, in a statement. “The photosphere is covered by convection cells, like in a boiling pot of water, and the larger scale convection flow is called supergranulation,” said lead study author Stuart D. ![]() The spacecraft’s data revealed that the coronal holes act like showerheads, where jets appear on the sun’s surface in the form of bright spots, marking where the magnetic field passes in and out of the photosphere.Īs magnetic fields pass each other, moving in opposite directions within these funnels on the solar surface, they break and reconnect, which sends charged particles flying out of the sun. “That’s going to affect our ability to understand how the sun releases energy and drives geomagnetic storms, which are a threat to our communication networks.” “Winds carry lots of information from the sun to Earth, so understanding the mechanism behind the sun’s wind is important for practical reasons on Earth,” said study coauthor James Drake, distinguished professor of physics at the University of Maryland, College Park, in a statement. Understanding the source of the solar wind can help scientists better predict space weather and solar storms that can affect Earth.Īlthough they can cause beautiful auroras, the solar storms can also impact satellites and Earth’s electrical grids. ![]() This flip causes the coronal holes to appear across the sun’s surface and release bursts of solar wind directly toward Earth. But during the maximum of the solar cycle, an 11-year period over which the sun’s activity gradually increases, the sun’s magnetic field flips. The fast solar wind doesn’t usually impact Earth. The slower solar wind, located in the same plane of the solar system as Earth, flows at a calmer 249 miles per second (400 kilometers per second). The faster solar wind streams from holes in the corona at the sun’s poles at a peak speed of 497 miles per second (800 kilometers per second). The far-reaching phenomenon also includes part of the solar magnetic field and extends well beyond the corona, interacting with planets and the interstellar medium. Solar wind is a continuous outflow of plasma, which contains charged particles like protons and electrons. It’s a test, and watching them pull it together amidst the chaos is what makes the series so captivating.The spacecraft was specially designed to eventually fly within 4 million miles (6.4 million kilometers) above the solar surface, and in late 2021, it became the first mission to “touch” the sun.Ī study detailing the solar findings was published Wednesday in the journal Nature. ![]() Pressure from within, like with Kaylie, or pressure from someone that doesn’t necessarily have your best interests in mind, like Ellen’s vendetta against Emily. While the competitions obviously come with a great amount of pressure, this episode depicts the pressure that these girls are constantly under from all sides. When Marty ( Erik Palladino), the National Team Coach, does, he’s fired, replaced by the nightmare that is Ellen Beals ( Michelle Clunie). However, no one is willing to listen to him, as they only see that Kaylie is getting better with her gymnastics, blind to the fact that she’s hurting herself to do so. ![]() And, after weeks of this, Kaylie’s coach, Sasha Belov ( Neil Jackson), is taking notice and becoming more concerned. Kaylie’s deep in her eating disorder, starving herself to be able to “perfect” moves that only Genji Cho can do. However, none of the girls are in the best head space to deal with this. The pressure is rising as the girls attend their last practice before World Trials, where there is a surprise announcement that not all the girls on the National Team will be able to perform at Trials, making the practice another competition.
