This is another piece of news about the black hole. We are talking about black holes frequently. There is new news that is forming related to the black holes. This is one such. That is not only a black hole. But it is a deep black hole. What are the specifications for that? We are here to talk about that. You know in the last year the picture of a black hole released to the public. I told you about that. Could you remember it??? Definitely you can.
First, we will see what the black holes are?? Before moving to the main topic, we have to take a rough idea.
We talked about the released picture of the black hole. Through that people saw the truth including things inside the black hole. Now it is not a secret in the future. I think the curiosity of the people relieved.
Now there is another special method to detect the above. Also, that is a new method. The name of that method is the x-ray echo. There is another black hole that came to the view. There is a certain location for that. The location is IRAS 13224 – 3809. There is a long-distance to it from us. I can tell you the length. That is approximately a billion light-years away. There is another important thing to tell you. There is a special thing around the black hole. That is the x-ray corona. I expect to tell you about the IRAS 13224 – 3809 and the x-ray corona. I’ll tell you both of them in the following.
Event Horizon and X-ray
Through the x-ray corona and the x-ray, echo scientists created a map. That is not only a normal map. That is a detailed map. Detailed map of the surrounding with the horizon. That is a special region. Through that light also cannot travel. There is even another way to describe it. That is the light cannot escape from the above area. Yes, that area is as powerful as that. That is known as the black hole’s event horizon.
We can’t find black holes through light. We can find that only by the materials. That only observation can be made when materials fall into the black hole. For that scientists have to wait very calmly and patiently. That is a great thing
These above things are more accurate than the above-received details. The second time details give clues about the evolution of the expansion of the black hole. Even though the above measurements, scientists can get an idea about the formation of the galaxies. In the above, I told you about a special galaxy. That is IRAS 13224 – 3809. There is a spacecraft assigned to observe the above galaxy. That is the MXM Newton spacecraft. The above spacecraft is to make observations about the cosmos rays.
You know that the above tests are done by the x-ray detectors. From the black holes, the x rays can be emitted. Most of the x rays directly travel to the cosmos. While some of the others travel in other directions. Some others move to the accretion disk.
There is a name for the name of that measurement. There is a time delay here. That is called the reverberation. Such a special name. The above incident helps to find the materials around the black hole. Especially these are gassy materials. Using the reverberation process the mapping has taken place. Using the above mapping the objects in very far also detected.
Scientists also need to measure another thing. That is the mass of the black hole. For that one thing had to be found. That is the origin place of the gas and the departure place of the above gases. According to the details of the above mapping. That is the mass. The mass of the above black hole is equal to the total mass of the two million suns. You know in one opportunity every experiment cannot be successful. Scientists tried this test about 16 times. The features of the scientists are like that. They didn’t stop until the success of their experiment.
We will discuss something for today. That ia an important topic.
This is a greek word. There is even a connection between the Latin term even. That means the crown. This is a cover. I mean this is like a cover. This above cover will cover the stars and the sun. It is very hot. Even that is hotter than the surface of the sun. The above corona is not uniformly covered the surface of the earth. In 1973 the above corona was captured by a special satellite. That is the satellite skylab.
The above are some brief details about the corona. I told you many important details. I think you are happy to hear the above. You can use the above details in a positive way. If there are new such types of facts I will tell you those related to them.
