Meteors are a constant threat to the planet

Faith is small

This is February 2013. As a result of the meteorite falling in central Russia, the number of injured exceeded eleven hundred. The number of people injured in a single such incident in modern times was described as extraordinary. After the incident, the Russian authorities had sent special teams for cleaning and relief in the affected areas. It should be remembered that the ten-ton meteorite Saqib came towards the earth at a speed of four thousand kilometers. At a height of about fifty kilometers from the surface of the earth, it began to break. The speed of this giant meteorite can be estimated from the fact that it could cover the distance of seventeen hundred kilometers from Dubai to Jeddah in just one second. While modern passenger planes cover this distance in two hours.

Meteors are bright celestial objects that come from the atmosphere and fall to earth. They are also called Shahabiyyah and shooting stars in common Urdu. In fact, they are meteoroids or projectiles that enter the Earth’s atmosphere and create brightness due to pressure and friction. When a meteor thus enters the atmosphere of the Earth (or another planet) and shines, or passes through its atmosphere and falls on its surface, it is called a meteorite. Shahabiyyah is also called Sang Shahab in Urdu.

Small meteors are of no importance. But large meteors are certainly rare. Saqib is originally a word formed from the Arabic word for hole, which basically means hole or hole. When the meteors enter the earth’s atmosphere and produce light, the linear path created by them is compared to the light coming out through the hole, and the use of “saqib” in the sense of bright or shining with the hole is called “Shahab-e-Saqib”. The word is created.

According to experts, meteorites are actually debris left over from the creation of the solar system about four and a half billion years ago, and research on them can possibly reveal what the composition of the early solar system was and that How did Earth-like planets form?

Scientists say that there has been an increase in the number of meteorite collisions with the earth compared to before. According to American space scientists, a new meteorite could create a more dangerous situation than the meteorites, asteroids or asteroids that fell in Russia in February 2013. It is useful to have an early warning system in such situations.

It should be remembered that in Russia, when the shining pieces of the meteor fell on the ground, people in the Chelyabinsk region of Central Russia were panicked. According to the local time, at twenty minutes past nine in the morning, a shower of meteorite fragments was seen in the Ural mountain range. It was considered a miracle that no one was killed in the widespread disaster. At the time, Chelyabinsk regional governor Mikhail Yuryevich told reporters that most people suffered minor injuries. When the pieces of the meteor fell on the ground, as a result, various components flew in the air and caused injuries to people.

Children were also among the injured. About two hundred children were given medical aid after this incident. From this the severity of the incident can be estimated. On the other hand, Russian President Vladimir Putin issued orders to immediately help the affected people and officials of the Ministry of Emergency Situations said that a strong team of 20,000 people has been dispatched to the affected areas. Apart from helping there, she will also take part in the cleaning work.

The position of scientists

According to the Russian Academy of Science, this meteorite, weighing about ten tons, broke up before it hit the ground. According to reports, the large part of this meteorite fell in a lake located one kilometer away from Chelyabinsk. Chelyabinsk region is located fifteen hundred kilometers east of the capital Moscow. There are also several factories, a nuclear plant and a center for the decommissioning and storage of nuclear material.

As a result of this event, NASA and a team of global scientists gained a detailed understanding of the impact on Earth caused by a small asteroid impact four years ago for the first time in history. In a press release issued on November 6, 2013, NASA said that the unprecedented data obtained as a result of the impact and explosion of an asteroid over the Russian city of Chelyabinsk on February 15, 2013 will give scientists a better understanding of this natural phenomenon. It is a revolution in understanding.

The Chelyabinsk incident was also well-documented by citizen cameras and other sources. This gave researchers a rare opportunity to examine the phenomenon and study its implications for near-Earth objects and develop strategies to mitigate threats to Earth’s defenses. Now scientists from nine countries have set a new standard for modeling the impact of future planetary collisions.

According to Peter Jenskins, a meteorologist and co-author of the report published in the journal Science: “Our goal was to understand all the conditions that led to the shock waves.” Jenkins, a meteorologist at NASA’s Ames Research Center in California and the S.E.T.I. Institute, spent the weeks after the event at the Institute of Planetary Dynamics of the Russian Academy of Sciences in Moscow. I participated in a study led by researcher Olga Popova.

According to Olga Popova: “It was very important for us to meet many citizens who had personal experience of this.” “They recorded a spectacular video of it and the experience is fresh in their minds.” By examining the videos and photos using the positions of the stars in the sky, Jenskins and Popova estimated that the meteorite traveled 19 km/h. Hit at the speed of seconds. When the meteorite entered the (terrestrial) atmosphere, it scattered into fragments, whose velocity reached 30 km at the (terrestrial) surface.

To those who were up to 100 kilometers away at that time, the light of the meteor was more visible than the sun. As a result of the intense heat, many pieces of debris fell from the bright yellow cloud. They were already vaporized and dissolved in the atmosphere. Scientists believe that the small meteorites that fell on Earth weighed between 4000 and 6000 kg. Among them was the 650 kg fragment that was recovered from Lake Chebarkal on October 16, 2013 by professional divers with the help of researchers from Ural Federal University.

A 59-member team of NASA researchers, after their study, suspected that the abundance of shock cracks contributed to the rock breaking up in the upper atmosphere. Researchers at Chelyabinsk State University analyzed the provided meteorites to determine the source of shock cracks and their physical properties.

They said that the shocks from the collision that created these cracks may have happened 4.4 billion years ago. According to the research team, this must have happened 115 million years after the formation of the solar system when a very important meteorite collision took place.

According to Jenskins, events so long ago affected the way the Chelyabinsk meteorite broke up in the atmosphere, creating damaging shock waves. Research is being done. This indispensable study is necessary to improve the way to change the path of an object on a potential collision course with Earth.

It should be noted that NASA announced at the end of 2013 that the initial project of Shahab-Saqib will be the first mission to control and remove the meteorite. NASA said that the study of meteors and comets gives scientists the opportunity to learn about the origins of the solar system, the sources of water on Earth, and even the organic molecules that made life possible.

Shahab-e-Saqib or space creatures

After the incident in Russia, in September 2015, the power system was affected by a meteorite in the Yucatan region of Ischmal, Mexico. People in the same area have reported several incidents of flying saucers and meteorites. After that, a burnt human body has also been allegedly found, which is being described as a space creature. It also has 2 legs. The experts related to this incident had considered this mysterious creature and said that it is a burnt piece of Shahab-e-Saqib which has been molded into a special shape by heat.

However, alien researchers disagreed and Scott Wareing, an expert on flying saucers, said that it is not a structure of an alien, but a spaceship, robot or space suit, because the fall of the meteorite that As heat is generated, no body can survive in this state. After the Shahab-Saqib collision, local people reported that they found fragments everywhere, by which they meant a piece of technology or invention. A round object was also found at the site which was said to be an alien robot or a helmet.

Astronomers and engineers from the UK designed a mission in 2007 to observe a future near-Earth meteorite, Epophis. Will pass very close. Scientists at Stevenage-based Astrium want to accurately estimate the meteorite’s orbit.

The British scientists’ designs also included the development of a small spacecraft called ‘Apex’. According to scientists, Epophis is not a threat to the world at the moment, but if it hits the earth, it can cause a lot of deaths in the world. Scientists think that 65 million years ago, there were many animals and dinosaurs in the world. The cause of death was also the collision of such a huge space object with the earth.
