See a Solar Snake Slither Across the Sun’s Surface – At 380,000 Miles per Hour

 


A "tube" of cooler atmospheric gases that is rapidly weaving its way through the sun's powerful magnetic field has been observed by the Solar Orbiter. The Solar Orbiter mission, which is led by the European Space Agency (ESA), has discovered a slew of fascinating new features. This is a fascinating new discovery. The fact that the snake was a forerunner to a much larger eruption makes it even more intriguing. 


On September 5, 2022, the Solar Orbiter spacecraft was making a close pass of the Sun on October 12, when the snake was seen. The "snake" is a tube of cool plasma suspended in the hotter plasma of the sun's atmosphere by magnetic fields. 


Plasma is a form of matter similar to the more common solid, liquid, and gas states. Because plasmas are so extremely hot, electrons leave their atoms and form a gas of charged particles. They are therefore susceptible to magnetic fields because they are charged particles. Plasma makes up all the gas in the sun's atmosphere because its temperature is more than a million degrees Celsius. 


The snake's plasma is following a particularly long segment of the sun's magnetic field that extends from one side to the other


Plasma is flowing from one side to the other, but the magnetic field is twisted very badly. "As a result, we're looking down on a twisted structure, which is why you're seeing this change in direction," explains David Long of the Mallard Space Science Laboratory (UCL), UK, who is leading the investigation into the phenomenon.


The images from the Solar Orbiter's Extreme-Ultraviolet Imager (EU I) were used to create the time-lapse video at the top of this page. In fact, the snake traveled for approximately three hours. That indicates, however, that the plasma must have traveled at approximately 170 kilometers per second (106 miles per second) or 612,000 kilometers per hour (380,000 miles per hour) for the distances required to cross the surface of the sun. 


The snake's origin in a solar active region that later erupted, releasing billions of tonnes of plasma into space, is what makes it so fascinating. This raises the possibility that the snake was a kind of forerunner to this event and that the Solar Orbiter's instruments caught it all


The eruption was one of the most intense solar energetic particle events that the spacecraft's Energetic Particle Detector (EPD) has detected thus far. 


According to David, "it's a really nice combination of datasets that we only get from the Solar Orbiter". 


Even more intriguing is the fact that NASA's Parker Solar Probe was able to measure the contents of the eruption thanks to the plasma from this eruption, which is called a coronal mass ejection. 


One of Solar Orbiter's primary scientific objectives is to observe an eruption and then sample the ejected gases using either its own instruments or those of another spacecraft. It will make it possible to develop a deeper comprehension of solar activity and the process by which it produces "space weather", which has the potential to disrupt satellites and other technology on Earth 


ESA is in charge of the international ESA-NASA space mission known as Solar Orbiter. It sent off on February 9, 2020, and celebrated its 1000th day in space recently

What Is Difference Between Chia Seeds And Flaxseed

Image
  Certain seeds have gained a reputation as superfoods in recent years. Examples include the well-known chia and flax seeds. Both have been linked to health benefits such as a healthier heart, lower blood sugar levels, and protection against certain types of cancer. However, many people wonder which of the two seeds is actually the healthiest. Both are extremely rich in nutrients. To answer this question, this article looks at the scientific evidence that supports each The Saliva Hispanic plant, more commonly referred to as the chia plant, is the source of the tiny oval-shaped chia seeds. Chia seeds are slightly larger and flatter than flax seeds. Flax seeds, on the other hand, have a slightly nuttier flavor than chia seeds. However, incorporating both kinds of seeds into a variety of dishes is simple Nutrition comparison Comparative analysis of the nutrients present in chia and flax seeds The major nutrients contained in a 1-ounce (28-gram) serving, or approximately 4 tablespoons,...

Overconsumption of Common Red Food Dye May Lead to Inflammatory Bowel Disease

Image
  Allure Red AC, a synthetic dye found in popular foods like Skittles, Doritos, Gatorade, Jell-O, and Fruit Loops, has been linked to an increased risk of developing inflammatory bowel diseases (I-B D S) such as Crohn's disease and ulcerative colitis if consumed frequently. The dye, also known as FD & C Red 40 and Food Red 17, is thought to have negative effects on gut health and increase inflammation, according to a small study done on laboratory mice. The study, which was recently published in Nature Communications, found that the additive directly breaks the gut barrier, which helps keep bacteria from getting in, and that it also makes more serotonin, a hormone and neurotransmitter in the gut. According to the report, this reaction alters the microbiome of the gut, making people more likely to develop inflammatory bowel conditions. What we have found is striking and alarming, as this common synthetic food dye may be a dietary trigger for I-B D S, said senior author W-A L-I U...

Border violence displaces 76,000 in Lebanon: Hezbollah

 The International Organization for Migration (IOM) of the United Nations reported on Friday that nearly three months of nearly daily fighting along the border with Israel had resulted in the displacement of more than 76,000 people in Lebanon. The boundary region has seen a flood of viciousness since early October, with blow for blow trades of fire forging ahead with Friday between Israeli powers and Hezbollah. In a report distributed on Thursday, the IOM said that the heightening had uprooted 76,018 individuals, predominantly in areas of southern Lebanon lining Israel. More than 80% of the dislodged Lebanese are remaining with family members, as per the report, and just two percent housed in 14 aggregate sanctuaries spread across the south of the country, predominantly in the seaside city of Tire and in the Hasbaya locale. The remainder, according to the UN agency, have relocated to homes or apartments further from the border. Cross-line brutality has left 175 individuals dead in ...
