First x-ray of the universe(e-ROSITA) taken

Scientists taken first X-ray of the universe
Russian and German experts have released the primary X-ray image of the universe obtained from an X-ray space telescope called E-ROSITA. Over 1,000,000 astronomical objects can be seen emitting X-rays in this X-ray.
E-ROSITA stands for Extended Roentgen Survey with an Imaging Telescope Array. eROSITA is the most important part of the telescope Spectrum Roentgen Gamma (SRG) which was sent into space in 2019. Although the aim of this space observatory telescope is to conduct research on "dark energy", for this purpose it exclusively include X-rays emitted from various astronomical objects.
It should be noted that X-rays are literally electromagnetic (electromagnetic) rays, but firstly, their energy is extremely high and secondly, the human eye can't see them. The sun emits X-rays, together with many other rays, which the protective layer of the earth's atmosphere prevents from reaching us and thus we are protected against the harmful effect of those rays.
The use of X-rays in diagnosis has been around for over a century and is common practice today. However excessive use of  X-rays may result in cancer.
In addition to the stars, when black holes "consume" matter scattered around them, they emit even more powerful X-rays, which are called the "last scream" of matter falling into the region.
This image shows many of the identical stars and black holes that are given different colors to create them visible to the human eye.
Remember that the e-ROSITA / RSG project covers a period of 4 years and will be completed in 2023. Its purpose isn't only to spot the supermassive black holes within the centers of galaxies, but also to have a better look at the thousands of galaxy clusters that are considered to be bound very tightly by weak gravitational force.
By learning thoroughly about the structure and motion of galaxy clusters, we'll be ready to know something about "dark energy", also called a "mysterious" energy that's cosmic. This is causing an increase of  the speed of spreading of the universe.
It will be interesting to read that in exactly some months,  eROSITA has observed a minimum of twice as many observations of the universe as X-rays have made within the last 60 years.
However, the work of eROSITA has just begun and it's expected that soon we'll see even more beautiful and detailed X-ray images of the universe.

which scientists born on June 4??

Scientists born on June 4 Robert F. Furchgott Born June 4, 1916; Died May 19, 2009 at the age of 92. Robert Francis Furchgitt was an American pharmacologist who shared the 1998 Nobel Prize in Physiology or Medicine (along with Louis J. Ignacio and Fred Murad) for his discovery that nitric oxide (NO) acts as a signaling molecule in the cardiovascular system. Is. Their joint work revealed a brand new mechanism by which the blood vessels in the body relax and dilate. Nitric oxide (NO), produced by a cell, works by penetrating membranes and regulating the function of other cells. Nerves and hormones are known as signal carriers, but this discovery was a completely new signaling principle in the biological system. Sir Christopher Cockerell Born June 4, 1910 Died June 1, 1999 at the age of 88 The English inventor of the hovercraft. He was an electronics engineer at the Marconi Company (1935-50) where he worked on aircraft carriers and radar. Then he started a boat rental business. ...

6 Misconceptions About Coronavirus Treatment

  6 Misconceptions About Coronavirus Treatment Coronavirus is spreading very fast in different countries of the world and so far no proven cure has been found.

In an Africa country a religious leader asked his followers to drink Dettol for coronavirus treatment. As a result about 80 people died. Some tips are useless but harmless but some are very dangerous.  Lets look what science says about some common misconceptions. 1-Garlic A number of posts have been shared on the social networking site Facebook suggesting that eating garlic can help prevent infections. The World Health Organization says that although garlic is "a healthy food with some antimicrobial properties", there is no evidence that eating garlic protects people from the coronavirus. This type of treatment is not harmful to health unless you trust it and ignore th...

Top 7 rivers where people can search gold

Top 7 rivers where people can search for gold  Most of the rivers of the world have gold deposits in their paths and contain dissolved gold particles in their waters. Due to geological changes many rivers still contain gold particles and large lumps in them. The race for gold search which began in the 19th century is now over. But there are still some places near rivers where ordinary people can find gold. Such rivers abound in the United States, and on some shores, ordinary people can try their luck for a golden treasure for a small fee. Earlier, the largest gold bar in California was discovered by an ordinary person. Many of the world's rivers are still famous for gold. The list includes many American rivers. 1.Reed Gold Mine, Charlotte, USA The Reed Gold Mine is located in Cabaret County, Midland, North Carolina, and is the first documentary commercial gold mine in the United States. In 1799, Conrad Reid found a 17-pound yellow "rock" in Little Meadow Creek. For thre...
