The peek at the black hole

  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

Blackhole image – black hole and the event horizon is visible in this picture

    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. 

 The corona 

fantasy of blackhole

    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.

SpaceX launch the crew vehicle to the higher orbit

You know more details about the crew vehicles by SpaceX. Those are the vehicles meant to travel to the universe. They are especially helping the ISS or the international space station. That is to crew transportation. Also, that will become like a journey. That means people can travel to outer space. We are going to the outer cities for picnics. Like that one day, people went to the universe. From that, they can see the planets and stars. On other days we see them in images. But think about how you can feel when you can see them real. 

   Here the above topic means the vehicle that means a mode of transportation of private citizens. That means the idea that I told. Also, that can go to the higher orbit. That distance means the distance that hadn’t ever before. The crew members can go for higher orbits. The scientists made their crew vehicle comfortable for four members. You know this is an excellent creation by SpaceX. 

Crew Dragon is in the space

  Not only SpaceX but also another member participated in this creation. It is the U. S based space adventures Inc. Yes, they are difficult to handle such a huge project. Therefore recently, both organizations announced the above crew vehicle could perform its activity. But the cost or the definite date had not been announced yet. 

   But this experience was previously done by seven crew members. Those tourists went to the ISS or the international space station. There is another one. That is the Russian Soyuz rockets. Only the crew members, such as scientists, can go to the International Space Station. But normal tourists could not go there. As I said above, they can go to higher orbits. That means the distance above the earth from 800 km and 1200 km. 

     This is previously planned for the transportation of the NASA crew members. Such a nice combination. NASA with SpaceX. As their plan, they will transport the above crew members to the International Space Station within this year. That will be later in the month. Also, I think you know that. In the last year, they have performed a test by using this above crew vehicle. That was successful. We can state that as another successful step in space history. There are no crew members there. 

   Then after that, approximately at the end of next year, that crew vehicle will perform its first flight with tourists. Sometimes on this occasion, there may be many customers expecting this valuable opportunity. Usually, a commander needs to perform such a flight. The commander can be a pilot. But for this kind of crew vehicle, there is no need for such a person. What is that?? Then how can such an instrument be operated?? That means the above crew vehicle is fully automatic. But if needed, the passengers can control the crew vehicle. 

Crew Dragon by SpaceX

  One of the customers has paid $35 million for the ten-day space tour. The first person to go to space is Dennis Tito. He is a Californian businessman. In 2001 he was lucky to have that experience. He paid $20 million for eight hours. He stayed inside the international space station. These are some main details about the crew transportation to the International Space Station or to the higher orbits. 

  Then you all know about SpaceX. But today I would like to tell you more about that. 

Something about SpaceX… 

   Actually, SpaceX means what?? That is the Space exploration technologies corporation. That name became SpaceX in the short form. You know this is a private organization while Elon Musk is the Head of this private company. 

  Their main goal is to colonize the planet Mars. They have produced several launch vehicles. Actually, there are many. They have succeeded in many chances. As in the above, sometimes they are working companions with the NASA organization. This organization started on the 6th of May 2002. They have created the first liquid-propellant rocket. 

SpaceX satellite

   The above SpaceX organization achieved many things for the first time. Some of them are SpaceX succeed in the launching of the Dragon spacecraft. Then they sent the same spacecraft to the International Space Station. Including the above, there are many other achievements. 

    At that movement, even they are trying another new project. Currently, SpaceX is in the project of the starship and the Starlink. Starship is a reusable rocket. Then the Starlink is the network of the global telecommunication system. There is another important fact. Usually, SpaceX is producing reusable rockets. Do you know the reason?? That is in order to minimize the production cost. 

  Now you know all the essential details of the SpaceX recent project. That is about the crew vehicle. And you know some important facts about SpaceX. You can expect some more in the future too. Do you like to know about Nasa, Click here

NASA stated that Antarctica is melting

 That is amazing news. Because we can’t believe it. Antarctica is a region that is not facing such a condition very easily. You know both regions Antarctic and Arctic are covered with ice glaziers. The coldest temperature was maintained there. Actually human beings can’t live in an area like the above. Now according to the explorations of the NASA scientists, they said that Antarctica faced a danger of melting. We can’t tell if that is good or bad. That is good for other people. Because they can even migrate to those areas to live. 

  But that is unfortunate for some animals. That means animals that live in cold conditions. Examples for polar bears and penguins. What can happen after the melting down of the whole Antarctica region? 

  Now we will see their proof and facts put forward for the melting down of Antarctica. 

Melting down of Antarctica 

At now, Antarctica is melting down

   The melting of Antarctica was recorded because of the heat waves. Definitely there has to be a reason for some incident. Therefore heat waves are the causing agent for the melting. Antarctica experienced that heatwave earlier in February. From that season there is a high temperature recorded under Antarctica. That means a temperature greater than the normal temperature. The recent proof of satellite shows some important details. That shows how heat waves affected the ice caps and the glaziers. 

   Do you know the special satellite that made these special images? That is the Landsat 8 satellites. Also, that shows the northern tip of the Antarctic peninsula. That recent closeup was done on the 4th of February this year. It showed there are ice caps in Antarctica the same as before. But later the next closeup was done on the 13th of February. There are blue items in there. Actually that means there are melted ponds. There are no ponds there. So those are surely the melted lands. 

   Not only us but also scientists are excited about this. They can’t believe even these ice glaciers melted so soon. Eagle Island is the research base of these conditions. Scientists didn’t see this condition as an advantage. They see this as a symbol of a hazardous situation. They worry about the future. 

  I told the reason for the above warm conditions. That heat waves are not difficult to recognize. They are capable of identifying the change in the temperature pattern when the note down the varying temperature. The heat waves liquefied around 20% of Eagle ‘s island. That is the seasonal snow accumulation. 

   Those are some main facts related to the melting down of Antarctica. Then we will see the founder of such a big secret. That is the worldwide famous institution NASA. We will see some facts about NASA. 

NASA & Antarctica

One of Nasa astronaut in the space, he is capturing images of Antarctica

   NASA means the national aeronautics and space administration. This is a worldwide famous company in the space science field. This is owned by the United Nations government. This was started on the 29th of July 1958. The above company has the motto of the for the benefit of all. NASA had performed the projects including the Apollo moon landing mission, Skylab Mission. Mainly NASA is helping the ISS. ISS is the international space station. Plus they are producing the crew vehicle. You know about that. One day humans can go to a universe similar to the journeys we are going on.

  Currently, NASA is continuing the research about Mars 2020. That is by the insight rover. Other than Mars NASA is continuing investigations of Saturn and the Jupiter. 

  Those are the main facts about the worldwide famous space authority. Then after that, we will see about the special instrument that made investigations of the Antarctic secret. That is, 

Landsat 8 imagined Antarctica

World’s Map by NASA 2018, Antarctica is in the bottom part of the image

    This is a production of the American earth observation satellite. On the 11th of February 2013, the satellite was launched first. Landsat is the short form of the Landsat data continuity mission. To make this NASA and the USGS cooperated with each other. This is an earth imaging Mission. During that Mission, it imagined the region of Antarctica. 

   Landsat has an estimated Mission time of about 5- 10 years. There are mainly two payloads in this Landsat. Those are the operational land imager and the Thermal infrared sensor. Those two collect data for the short wave thermal band and the longwave thermal band. 

    You know there is a ground system. That has certain functions. Those are controlling the satellite and commanding. And the management of the satellite. 

   So I described all the related details about the Antarctica mission. Sometimes this condition can disappear after some time. That can be because of this dry condition. However, NASA and the Landsat 8 will continue their work in the future too. We can expect more from them. We can know them.
