The black hole has always been a mystery to man. The availability of photographs of Sagittarius A is an important milestone in space research. This photographic study illuminates the ‘dark’ lilies in the center of our galaxy.
Looking at the moonlit sky it is hard to find a person who will not go anywhere. But there are many other elements in the sky besides the stars. The most mysterious of these elements is the black hole. What is a black hole? Some more information is needed to answer this question. Just as humans have a life cycle, so do stars. That is, he is born, grows very slowly, grows up, ages and eventually dies. This is the real interesting part. We do not know what happens after the death of man; But after much research, scientists have discovered what happens to a star! There are four possibilities for what happens when a star dies. One of them is the black hole.
In short, a black hole is the state of a dying star. It has tremendous contraction as it is formed. Massive mass is small in size. This creates massive density and gravity. No matter how intense this gravitational force is, if an object gets some distance around the black hole, it will be pulled towards it with tremendous speed. Not only objects, but also light are drawn. That is, light does not come to us from such a hole. So it looks black. That is why it is called ‘Krishna’ Weaver. We still do not understand exactly what is inside the black hole and what happens to the objects inside. Many miracles take place in the area around him. For all these reasons, the subject of black holes has become a mystery not only to scientists but also to the general public.
There are billions of such groups in space. Such a group is called a galaxy. Our galaxy is called the Milky Way. Researchers have long believed that there should be a large black hole in the center of the galaxy. This is logical. See how- the reason the moon revolves around the earth is the gravity of the earth. The earth revolves around the sun due to the gravitational force of the sun. Now the next question is, is the sun also orbiting ‘something’? The answer is yes. The sun and all other stars revolve around the center of the galaxy. That is, there must be something at the center of gravity. This object is a giant black hole. The existence of such a statement has now become universal. A similar hole is in the center of our Milky Way galaxy, which has recently been proven with the help of mathematics and observations. It was named ‘Sagittarius A’. This research won the 2020 Nobel Prize in Physics. But still, without seeing an element – at least without looking at its photographs, you will not be satisfied and you will not believe in its existence. This is scientifically correct. In the case of a black hole, the biggest problem with taking such a photo is not only the light coming out of it, but how to take a photo of it? But how do you become a scientist if you succumb to such difficulties?
To overcome this challenge a massive system was set up and examined at length on the ‘Sagittarius’. Researchers have recently succeeded in capturing his photographs and there is no doubt that this phenomenon will be a milestone in astronomy. Scientists have wondered if this is the first photograph of a hole in the center of our Milky Way galaxy.
This crater in the center of our galaxy is called the ‘Giant’. Because if it is placed on one side of the scales, it will take 40 million suns on the other side to balance it. This enormous mass (relatively) lies in a sphere with a radius of about 2,400 km.
How far is Sagittarius A from Earth? This distance is 26,000 light years. So the photograph we have today is 26,000 years old! There are a large number of stars at some distance around this crater. When the gas in it pulls that hole towards you, it emits radio waves. The black hole image was created with the help of those waves. It took more than a decade of research to accomplish this very difficult task. The brightness in this image is created by radio waves to external opacity. The middle part is black because the waves trying to get out of that part are pulled through the details. In that sense the film is truly a ‘shadow’ film.
How did you come up with this film? The researchers developed a large system called the Event Horizon Telescope (EHT). The system is a network of eight radio telescopes. These telescopes are arranged in six locations away from each other on Earth. Telescopes have been installed at various locations in the United States, from the state of Arizona to the South Pole and from the island of Hawaii to Spain. This unique design created a dish antenna with an area of approximately 12,000 km in diameter. The system operates at the same resolution as a dish antenna with a diameter of 12,000 km.
Getting a black hole picture is a very difficult task. Using all of the radio telescopes mentioned above, scientists have collected huge amounts of Veda. How big? So 100 Million TickTalk Videos Can Be Made! Technically three and a half petabytes. This release is too large to be sent via Google Drive or similar. So each telescope stores this release on its own hard disk and sends those disks directly to the main hub. There all these factors are put together and how they are related to each other is determined. Thousands of such images were formed. Their ‘average’ accompanying film.
This hole in the heart of our galaxy is not ‘silent’. There is always something going on. Hot air bubbles are drawn in from nearby stars, causing a sensation. As a result, the waves emanating from those gases also undergo major changes. Fast moving electrons create a magnetic field. That area is also constantly changing. This makes it even more difficult to get a picture of the black hole. Also, you can not clearly see the ERV in the center of your galaxy. Because it is surrounded by a variety of gases and dirt. Therefore, observing a black hole in such a center is even more challenging. So many sophisticated computers and many advanced algorithms were used in this experiment. It is important to note that this figure proves that Einstein’s mathematical theory of relativity 100 years ago was correct in determining the approximate diameter of the sides around a hole. Einstein’s supernatural intelligence came to the fore once again. A detailed study of this film is now underway. This study sheds light on the ‘dark’ lilies in the center of our galaxy.
What is the use of such research in astronomy for the common man? A separate article will be written to give a detailed answer. Turtas cites only one example – if Einstein had not proposed the theory of relativity, GPS, Google Earth, Google Maps, etc. would not have been born today!
