Scientists have uncovered the mysterious source of a key solar phenomenon that has long-puzzled experts.

The Solar Orbiter spacecraft, developed by the European Space Agency (ESA) with contribution from NASA, discovered numerous tiny jets of material escaping from the sun's atmosphere.

Each of the tiny jets lasts between 20-100 seconds and expels plasma—a stage of matter consisting of superheated, charged particles—at a speed of around 224,000 miles per hour. The jets could be a long-sought-after source of the solar wind, according to a study published in the journal Science.

Our sun's outer atmosphere, or corona, constantly spews out a stream of plasma, known as the solar wind, that can reach speeds of more than 1 million miles per hour. This stream, which contains embedded solar magnetic field, expands throughout the entire solar system reaching far beyond the orbit of Pluto before it meets the interstellar medium.

The solar wind and magnetic field inflate a vast "bubble" in the surrounding interstellar material, which is known as the heliosphere.

Variations in the solar wind can produce several space weather phenomena that affect Earth. For example, under certain circumstances, it can interact with the Earth's magnetic field in a way that produces auroras.

Meanwhile, particularly high-speed streams of solar wind can result in geomagnetic storms that have the potential to disrupt navigation systems and produce harmful currents in power grids and pipelines, among other impacts.

"Understanding the solar wind is a key prerequisite for understanding space weather. Results like these are steps towards understanding the dynamic nature of the solar wind," ESA solar physicist Daniel Müller told Newsweek.

The solar wind is a fundamental feature of the sun but understanding exactly how and where it is generated has proven elusive, even though scientists have been studying the question for decades.

But the advanced instrumentation on the Solar Orbiter, considered the most complex scientific laboratory ever sent to study our star, has now shed new light on what drives the generation of the solar wind.

For the latest study, scientists examined data collected by the Solar Orbiter's Extreme Ultraviolet Imager (EUI) instrument.

In March 2022, this instrument took images of the sun's south pole, which researchers then analyzed. This revealed numerous short-lived and tiny jets, each one expelling plasma into space.

"We could only detect these tiny jets because of the unprecedented high-resolution, high-cadence images produced by EUI," Lakshmi Pradeep Chitta with the Max Planck Institute for Solar System Research, Germany, and the principal author on the paper, said in a press release.

The tiny jets that the researchers observed could be seen emanating from a structure on the sun known as a coronal hole. These vast holes are regions where the sun's magnetic field does not turn back down into the star. Instead, the magnetic field stretches out deep into the solar system.

It's been known for decades that some of the solar wind that the sun produces is generated in these regions. (Coronal holes which are most prevalent and stable at the sun's north and south poles, produce solar wind of relatively high speed. The solar wind that emanates from the equatorial regions of the sun, where there are fewer coronal holes, on the other hand, tends to be slower in speed).

But while scientists knew that high-speed solar wind originated from coronal holes, how exactly the plasma was launched remained something of a mystery. Now, the latest findings suggest that the tiny jets may be responsible for launching the plasma that feeds the solar wind as they travel away from the sun.

The study also challenges previous assumptions that the high-speed solar wind from coronal holes emerges in flows that are relatively steady. The researchers found that to a large extent, this flow is not actually uniform but is instead highly intermittent.

"This paper shows that also the fast solar wind is much more dynamic than originally thought," Müller told Newsweek.

The jets that the team discovered produce relatively little energy in the grand scheme of solar activity. For context, the most powerful corona phenomena, known as X-class solar flares, produce around a billion times more energy than so-called nanoflares. But the tiny jets are even a thousand times less energetic than these nanoflares.

The fact that the scientists saw so many of the tiny jets in the recent observations indicates that they are expelling a substantial fraction of the material that can be found in the solar wind.

"I think it's a significant step to find something on the disc that certainly is contributing to the solar wind," David Berghmans, principal investigator for the EUI instrument with the Royal Observatory of Belgium, said in the press release.

But it is possible that there could be other even smaller and more frequent events that could be contributing further.

Future research will be able to shed light on this issue. Currently, the Solar Orbiter is circling the sun close to the star's equator. This means that the tiny jets at the South Pole could only be seen edge-on, making it harder to measure some of their properties.

But as the Solar Orbiter mission continues, it will gradually incline its orbit toward the uncharted polar regions

"In a few years, we will see them from a different perspective than any other telescopes or observatories so that together should help a lot," Müller said in the press release.

The latest findings, alongside other observations being made by the Solar Orbiter, have implications for our understanding of space weather, according to Müller.

'With the Solar Orbiter mission, which is also sampling the solar wind at the location of the spacecraft, we can measure the variability of the solar wind at different distances between the sun and Earth," he told Newsweek. "This will help scientists build better computer models to forecast the solar wind and space weather conditions near Earth based on solar observations."

BIGHUGE SKETCHDUMP TIME as promised! These are doodles from 2021 or so, inside joke stuff with some friends, the context for half of these though was this really dumb idea for a "Tiny Titans" game mode where you run around as a pilot-sized titan that is about as strong as the full sized ones but also really zoomy A good idea? Probably not, but it's a contender for an "april fools'" concept or whatever Anyway, enjoy the chaos!

Betrayal (An ATLA analysis)

It's really important to me, how, in the Avatar universe, the person who's at the right side of the throne (essentially the right hand), always betrays the one sitting on the said throne.

Exhibit A:

Long Feng, kept the King oblivious to the Hundered Year War and handled all matters that are not partying or charity events, making him the de facto ruler of Ba Sing Se without even the King's knowledge, essentially paving a way for his betrayal.

Exhibit B:

Zuko, said it himself, that he was literally at his father's right hand. Even Azula got only the second best seat. And the next thing Zuko does? He betrays his father. I know what you're all thinking. But didn't Zuko already betray him before? Well, he did when he released Aang from Zhao as the Blue Spirit. But, the important point is, his explicit orders were to capture the Avatar to restore his honour. It didn't matter which methods he used to do it. He only ever openly betrayed his father during the eclipse and that was after he was placed at the right hand in the war meeting.

Exhibit C:

Mai, a betrayal that was a turning point in Azula's declining mental health. But hey, Ty Lee betrayed Azula too, right? Yes. But that doesn't change the fact that Mai did it first and she was sat at Azula's right hand. Mai never really feared Azula. She only followed her around out of her own will. Ty Lee on the other hand, when Azula recruits her at the circus, is found showing fear. She only had the guts to betray Azula after Mai did.

It really puts into perspective how Ty Lee couldn't betray Azula until provoked because she feared her, and Mai betrayed Azula because she didn't fear her enough. It further solidifies Azula's stellar line, "You should've feared me more!", insisting that if Mai had feared her more, she wouldn't have betrayed her. This especially holds true because it's later explained by Azula herself that, "Fear is the only reliable way." Fear kept Ty Lee in line but liberalised Mai cuz she didn't fear Azula more.

But all that goes out the window because Ty Lee betrayed Azula too. This is also one of the main reasons why Azula banishes most of the people around her. Because, "None of them can be trusted", and she trusted Mai as she knew Mai never feared her. It hurts her deeper because she trusted Mai and let her mantra of "Fear is the only reliable way" go, and guess what happens? She betrays her.

This solidifies three things in her brain: 1. Trust doesn't work, and, 2. Fear doesn't work either. 3. Nothing works, really.

Therefore, her action of banishing everybody with, "Sooner or later they all would've betrayed me."

This works for Exhibits A and B too. Long Feng never feared King Kuei and King Kuei completely trusted him until he learned of his betrayal. Trust didn't work, and fear didn't work either.

Zuko had never trusted his father. He only feared him. He has a physical scar on his body to prove it. But once that fear starts to deteriorate, he openly confronts his father and betrays him, letting go of his fear with, "It was cruel, and it was wrong!". Trust didn't work, and fear didn't work either.

So, what does work?

Well, the answer is pretty simple.

Love.

Love works. Any number and different kinds of love, be it platonic, or sibling, or romantic, it doesn't matter. It is foolproof!

Genuine care and affection for a person, doesn't let you betray them that easily. It's what made Sokka decide they should help Aang in Book 1. It's what made Yue turn into the moon. It's what made Toph come back to the Gaang again after she stormed off in Book 2. It's what made Aang come back for Bumi in Omashu in Book 2. It's what made Zuko find his path to Iroh again in Book 3.

The lack of love (from her own parents) is what made Azula's mental health deteriorate, as she thought nothing worked; it's depressing because she doesn't know that love actually works, cuz she's never known or experienced love her entire life, so she doesn't even consider it as an option.

The lack of love is what made the Dai Li betray Long Feng. The lack of it drove Zuko's betrayal to Ozai, Mai and Ty Lee's betrayal to Azula and even Jet's betrayal to Katara.

This could go on and on, but the end point here is that Azula's words on betrayal are true, but only when love is taken out of the equation. Love is the 'X' factor. Without it, there really is no equation, as all leads to zero.

Zuko and Sokka try to tell Katara that Jet is a jerk, but she won't listen. She's decided that Sokka has been hanging out with Zuko for too long.

Snowflakes! Dice is guarding the scissors... as he should.

*sigh* Mine looks stupid. I think I made it wrong... why is it a triangle

Oh no, Sarge turned his back...

Aughhhk help they're trying to kill me!

CT-6273, this is why we cannot have nice things. If you can't behave, then you can't participate.

*ignoring the scene* Heh it's finished.

~ Wing decided that he cannot, in fact, behave. Time out 😏~

Oh, hey Wing. Have you decided to join the party again?

Luck: *sighs*

Wing! We worked so hard on those!

The heck... is happening...

Dice: *just doesn't even care anymore*

“Jet House,” Zala County, Hungary,

The project was initiated by an undaunted 12-year-old client named Lujzi, who dreamed of a playhouse she could retreat to with her friends. From Lujzi’s vision, the design team emerged with a functional tiny home which, in their words, is “more reminiscent of a beautiful design toy than a building.”

Lucky Girl!
