NASA has found new evidence that our Sun is not an ordinary star

NASA has found new evidence that our Sun is not an ordinary star 92

THE NASA Parker Solar Probe made the closest flight ever to the sun in August 2018, collecting vast amounts of data using cutting-edge scientific instruments at a distance of 24 million kilometers – a mission that also set the highest speed record ever achieved by a man made object. 

About two years ago, NASA launched the Parker space probe toward the Sun, which finally reached the distance closest to our star and transmitted the first results of its observations of the luminary. It turned out that the strangeness in the behavior of the magnetic field of the Sun, including its ultrafast turns, lasting only a few seconds, does not end there. How can our seemingly well-studied star surprise us?

Scientists are beginning to spread what they have learned from the collected data. Four new articles published in the Nature magazine reveal new discoveries that may rewrite the way we understand the way stars are born, evolve and die. They can also help us find new ways to protect astronauts from harsh space conditions while traveling long distances through the Solar System.

Our sun may be weirder than it seems

Why is the corona of the sun hotter than its surface?

According to the portal newsweek.com, the first results of the mission were published in four scientific articles of the journal Nature. Despite the fact that the Sun is a key factor in the existence of life on Earth, there are huge gaps in our understanding of the whole multitude of phenomena occurring in its vicinity. So, it is known that the corona – the outermost part of the atmosphere – is much hotter than the surface of the Sun, reaching about a million degrees Celsius compared to 5500 degrees. The reason for this phenomenon is still unknown to scientists. At the same time, our star also produces the so-called solar wind, which constantly bombards Earth’s magnetic field. However, how exactly and why does it arise?

In order to help specialists understand such difficult issues, the Parker probe was designed, which came closer to the Sun than any other artificial object in the history of mankind. During his last three flights, scheduled for 2024 and 2025, it will approach the surface of the Sun at a distance of 6 million kilometers. Currently, the solar probe rotates at an approximate distance of about 24 million kilometers from our star at its closest point from the star.

The solar corona is fraught with many mysteries

The first studies of the space probe were aimed at studying the solar corona and its magnetic fields. It is known that it is the corona that produces the electrons of the solar wind, which are noticeably accelerated, leaving the place of its appearance.

Stuart Bale, principal researcher of the instrument cluster on board the probe at the University of California, Berkeley, said:

The complexity was mind-boggling when we began to examine the data. Now, I got used to it. But when I show colleagues for the first time, they are impressed.

The most surprising finding that the teams made was that the magnetic fields emanating from our star seemed to unexpectedly spin back and forth, causing local disturbances – what scientists called ‘switchbacks’ – which might even make them point back to the sun a few times.

The cause of this is still a mystery to scientists, but they can enable us to understand how energy flows away from the sun and throughout the solar system.

Justin Kasper, principal investigator at the University of Michigan, said in announcement:

Waves have been seen in the solar wind since the beginning of the space age, and we assumed that closer to the sun the waves would get stronger, but we did not expect to see them organize themselves at these structured and coherent peaks of speed.

Using new observations, the team found that while a “fast” solar wind, whose speed can reach 900 kilometers per second, comes from large holes in the corona at the North and South poles of the Sun, a “slow” solar wind comes from smaller holes in that part of the corona, which is located near the equator. It is known that the fastest recorded solar winds moved at a speed of 1.8 million kilometers per hour.

A team from NASA has also proven that the solar wind revolves around the Sun 10 to 20 times faster than standard models predicted. Such impressive speeds can be associated with unexpected changes in the magnetic field of a star. Researchers have discovered that magnetic fields can be traced down to coronal holes, sometimes suddenly turning as much as 180 degrees in just a few seconds.

Nicola Fox, director of the Heliophysics Division at NASA headquarters, said in the statement:

The sun is the only star we can look at close. Getting source data is already revolutionizing our understanding of our own star and stars throughout the universe. Our small spaceship is facing brutal conditions to send home surprising and exciting revelations.

Currently, the Parker solar probe continues to revolve around our star, getting a little closer with each circle. Activity on the sun increases and decreases during the 11-year cycle, which is currently in the “solar minimum”, characterized by fewer sunspots than usual. In the coming years, the activity of the Sun will increase until it reaches the so-called “solar maximum”, which will occur at the end of the mission of the Parker probe in 2024.

The mystery of the “Mandalorian” with a Jetpack flying behind a plane is revealed

The mystery of the “Mandalorian”    with a Jetpack flying behind a plane is revealed 108

Documents have been released revealing the secret of a man with a rocket pack who flew behind passenger planes, according to The Drive.

The owner of The Black Vault, John Greenewald, took advantage of the US Freedom of Information Act to secure the publication of material relating to the rocket pack incident. From the records of the air traffic controllers’ conversations, which he received, it follows that the man maneuvering at an altitude of about 900 meters was noticed by several pilots. At the same time, the radars did not record a single object that would correspond to their description.

It also turned out that in early September 2020, government officials contacted David Mayman, the chief tester of the California-based company Jetpack Aviation, which develops rocket packs. Meiman said that the company had not flown for several months, and questioned the existence of rocket packs that would allow them to climb and hold at an altitude of 900 meters.

Another letter provided to Greenwald mentions that the FBI interrogated an American Airlines pilot who spoke of a man with a jetpack. During the conversation, he confirmed that the figure he noticed resembled a drone in the form of a man from a video filmed at the German Aircraft Modeling Festival in 2019.

This is a radio-controlled drone that was built by model aircraft designer Ralph Kayser. It resembles a life-size human figure, but weighs less than five kilograms. The Rotor Drone Pro website wrote that the device is made from a paintball suit stuffed with packing film and can stay in the air for up to eight minutes.

The incident leading to the investigation took place on August 30, 2020. According to press reports, an unidentified person with a jetpack flew approximately 270 meters from an American Airlines plane landing at the Los Angeles airport. In October, the man with the rocket pack was reported by several other pilots in southern California.

An abnormal phenomenon on Earth captured from space: NASA and ESA have never seen such lightning

An abnormal phenomenon on Earth captured from space: NASA and ESA have never seen such lightning 109

The Atmosphere-Space Interactions Monitor (ASIM) observatory has recorded five blue jets , an anomalous type of lightning that strikes from the top of a thundercloud into the stratosphere. This is reported in an article published in the journal Nature.

On January 20, a video filmed from the International Space Station was posted on the channel of the European Space Agency, which puzzled all academics who study the atmosphere and build theories about how everything works there:

The 10 microsecond jets were sighted on February 26, 2019, near Nauru Island in the Pacific Ocean. One of the lightning flashes produced a jet that reached the stratopause – the boundary between the stratosphere and the ionosphere at an altitude of about 50 to 55 kilometers. In addition to the jets, “elves” were recorded, which are expanding rings of optical and ultraviolet radiation in the stratosphere, lasting no more than a millisecond.

Electrical phenomena in the upper atmosphere are poorly understood and attract a lot of attention from physicists from around the world. They are short-lived and vary greatly with altitude. 

Blue jets occur during electrical breakdown between the positively charged top of a thundercloud and the negatively charged air layer above it. As a result, a leader is formed – a conducting channel of ionized air, through which the discharge propagates. However, in this case, the radiation from the leader was weak, which indicates that the leader itself was short compared to the conductive channels of conventional lightning.

The blue jets belong to streamers – branched filaments of electrical discharges, similar to those generated by Tesla coils. In addition, blue jets are more likely to occur as a phenomenon than previously thought.

Some of the most mysterious are the “elves”. Their name comes from the abbreviation ELVES , which stands for “Emission of Light and Very Low Frequency perturbations due to Electromagnetic Pulse Sources.”. These phenomena reach four hundred kilometers in diameter and occur at an altitude of about one hundred kilometers. The list of optical phenomena associated with electrical discharges in the upper atmosphere does not end there. There are also TROLL , Pixie , Ghost, and Gnome , but their nature is even less understood. 

There is nothing like this, that is, such strange huge lightning has never been observed before. Something is happening in the Earth’s atmosphere, and it started quite recently. How it will end and what will result in – we do not know, since people living today have no such experience.

Ancient asteroid sent dinosaur bones into moon

Ancient asteroid sent dinosaur bones into moon 110

The impact of the asteroid that destroyed the dinosaurs 66 million years ago was so powerful that it sent into space huge volumes of earth’s soil and rocks from the crash site. But together with them, he could send into orbit the remains of living beings, including dinosaurs.

Such a possibility is discussed in the book “The End of the World” by the scientific journalist and winner of several awards Peter Brannen, according to the Daily Mail.

It is known that an asteroid or meteorite about 10 km in size collided with the Earth 66 million years ago, forming the Chikshulub crater on the Yucatan Peninsula in Mexico. About 15 trillion tons of ash and soot were thrown into the air. Because of  this, during the day it was dark on Earth, like a moonlit night.

As a result of the lack of light in plants, photosynthesis slowed down, which could lead to a decrease in the concentration of oxygen in the atmosphere. Temperatures on continents dropped by 28 ° C, in oceans by 11 ° C. The disappearance of phytoplankton has led to the extinction of zooplankton and other marine animals. Other species died after them. 

This is one of the largest mass extinctions in the history of the Earth, which is called the Cretaceous-Paleogene. Brannen, trying to make the numbers more descriptive, points out that the asteroid (or meteorite) was larger than Everest and crashed into the atmosphere 20 times faster than a flying bullet. At the same time, the pressure of the atmosphere was so strong that a crater in the Yucatan began to form even before the asteroid fell.

The “response” release of soil into the atmosphere occurred only within a second or two after the impact and was incredibly powerful.

“So there are probably little pieces of dinosaur bones on the moon,” Brannen suggests.
