Although the solar wind is an essential feature of the Sun, understanding how and where it is generated by the Sun has proven elusive, and has thus been a major focus of study by scientists for decades.
Recently, a recent study published in the journal “Science” – the European Space Agency and NASA’s “Solar Orbiter” spacecraft revealed numerous small jets of material ejected from the Sun’s outer atmosphere.
Each burst lasts between 20 and 100 seconds, and releases plasma at speeds of around 100 kilometers per second. These jets could be the source of feeding the solar wind, something scientists have been waiting to discover for a long time.
The solar wind typically consists of charged particles called plasma, which are constantly ejected from the Sun and spread outward through interplanetary space, hitting anything in its path, creating the aurora borealis when the solar wind collides with Earth’s magnetic field. .
Thanks to its excellent instrumentation, the Solar Orbiter has taken an important step forward in understanding the source of the solar wind. The data came from the Extreme Ultraviolet Imager (EUI) instrument on board the Solar Orbiter.
According to a press release published on the European Space Agency’s website on August 24, images of the Sun’s south pole taken by the instrument on March 30, 2022, revealed faint, short-lived features associated with small jets of plasma. Atmosphere to Sun.
“We were only able to detect these tiny jets because of the unprecedented high-resolution, high-frequency images produced by the ultrasound imaging instrument,” says Lakshmi Pradeep Chetta of the Max Planck Institute for Solar System Research in Germany. Paper describing this work. Ultraviolet”.
The instrument detected solar plasma at a wavelength of 17.4 nanometers at one millionth of a degree, and analysis of the images showed that the faint features revealed by the imaging are caused by the ejection of plasma from the solar atmosphere.
Flow is discontinuous and not always constant
Researchers have known for decades that much of the solar wind is associated with magnetic structures called coronal holes, which are regions where the magnetic field does not return to the Sun, but instead, extends deep into the solar system, where plasma flows with the magnet. Field lines travel to the open, solar system, forming the solar wind. But the question is: “How is plasma fired?”.
The traditional assumption is that as the corona heats up, it naturally expands and exits along some of its magnetic field lines, but new findings challenge the assumption that the solar wind is formed solely as a result of the corona’s steady, steady flow.
Within the corona, there is a difference between large-energy solar flares, billions of times larger than so-called nanoflares. As for the smaller jets detected by the solar tracker, they are less active than that.
These tiny jets emit about 1,000 times less energy than a nanoflare, and much of that energy dissipates into the plasma. The ubiquity of these small, faint jets suggests that they eject much of the material we see as the solar wind.
“Finding something in the disk that definitely contributes to the solar wind is an important step,” says David Bergmans of the Royal Observatory of Belgium and principal investigator of the Super Imaging Tool about what the new images reveal.
Currently, the Solar Orbiter is orbiting the Sun near the equator, with the Superior Imager imaging across the South Pole.
As the mission continues, the spacecraft will gradually adjust its orbit around the polar regions. At the same time, the Sun’s activity will progress during the current solar cycle and coronal holes will begin to appear at different latitudes, providing a unique new perspective.
So researchers are eager to see what new they can glean about solar activity, a research mission that extends beyond the solar system.
Only the Sun can observe its atmosphere in such detail, and this could be reflected in understanding what is happening in other stars as well. This makes these observations the discovery of a fundamental astrophysical process.
If you were expecting to see a revolutionary design for next year’s Samsung Galaxy S24, this news might disappoint you. Unofficial images released by the upcoming phone reveal SmartPrix With the cooperation of the leaker OnLeaks About a phone that looks a lot like the current Galaxy S23, with a square design and three raised camera lenses, minus the obvious protrusion.
Based on this leakage, the visible changes will be small. SmartPrix says the Galaxy S24 is slightly longer and thinner than its predecessor, the S23, and the overall screen size is said to be slightly larger at 6.17 inches instead of 6.1 inches. According to the website, three more camera lenses are visible on the back of the phone SamMobile, and it is said to come with the same resolution as the S23; 50-megapixel main camera, 12-megapixel wide-angle camera and 10-megapixel telephoto camera with 3x optical zoom.

The leaker claims that the Galaxy S24’s display will be 1080p with a brightness of 2,500 nits. The battery size is said to be 4,000 mAh and the maximum charging speed is 25W.
Replicas of the phone in the US are likely to get a 2024 flagship processor from Qualcomm called Snapdragon 8 Generation 3. Exynos processor in other global markets after using Snapdragon exclusively for Galaxy S23.
Rumors also suggest that Samsung might launch the Galaxy S24 a little earlier in the year compared to its previous two flagship phones that were released on February 1, 2023 and February 9, 2022. Galaxy S24.
Apple also applies the same strategy to the design of the phone, as it tries to maintain the shape of the design while adding very small improvements, and we can start to notice the effect after several generations of the same phone.
The planet Uranus is one of the outer planets in our solar system. Uranus is considered the seventh planet after the Sun, and the third gas planet in the Solar System after Jupiter and Saturn.
Here are some interesting facts about the planet Uranus:
1. Its location and size: The planet Uranus is located in the solar system and is the seventh planet after Saturn. Uranus is the third largest planet in the Solar System in terms of diameter and size, four times the diameter of Earth.
2. Its peculiar spin axis: Uranus has an unusual spin axis because it is strongly tilted at approximately 98 degrees, meaning it spins on its side. This means that Uranus’ north pole and south pole experience longer periods of darkness and longer periods of light during the year.
3. Its icy composition: Uranus is believed to consist mainly of hydrogen and helium gas, with an outer layer of clouds containing ammonia and methane. These icy gases are responsible for Uranus’ cool blue color.
4. Discovery of rings: The rings of Uranus were discovered by observation from Earth in 1977. These rings consist of small particles of dust and ice. Unlike Saturn’s rings, Uranus’ rings are faint and difficult to see.
5. Space exploration: Uranus has not been visited by any human space mission, but it was visited by the Voyager 2 probe in 1986. Voyager 2 provided many detailed images of the planet and transmitted useful data about its atmosphere and rings.
