What is the use of the “high-resolution image of the sun ’s surface” recently taken by humans to study the sun?
As the largest energy source in the solar system, the energy released by the sun per second is equivalent to burning 130 million tons of standard coal. The energy released by the earth is equivalent to 5 million tons of standard solar radiation energy per second.
So the energy absorbed by the earth only accounts for one-two billionth of the total solar energy, but it is one of the "insignificant" one-two billionth that allows the earth to evolve and support thousands of souls.Even the fossil fuel consumed by human civilization today is, in a sense, solar energy stored in ancient times.
The National Science Foundation announced the clearest image of the solar surface taken by the Daniel Inoue Solar Telescope to date.
This astronomical device named after Japanese-Americans is currently the largest-caliber solar telescope on the planet.It has captured details of the "scale" or "cell" -like structure on the surface of the sun, and has seen the surface of the sun in the past. "The turbulent heat wave is different. The surface of the high-definition sun looks like "flowing gold" and it seems to be "quiet." But astronomers tell us that the area of each scale or cell is about 700,000 square kilometers. They are essentiallyThere is still a surging high-temperature plasma. The so-called "calmness" is just the illusion we have on the earth 150 million kilometers away.
The high-resolution images of the solar surface currently released are just a small test before the official operation of the Daniel Inoue Solar Telescope. In June 2020, after the telescope was officially completed, astronomers will let it make an official observation of the sun and hope to pass itDecipher the formation of solar storms and the changes in solar magnetic fields.
The Parker Solar Detector launched on August 12, 2018, completed its fourth near-day flight on January 29, not long ago. By 2024, the distance between the Parker and the Sun will be shortened to 616.Ten thousand kilometers, by then it will be much closer to the sun than Mercury.
Parker's mission is to better detect the solar wind and try to crack the formation mechanism of the solar wind. At the same time, with the help of high-energy particles emitted by the sun, it provides a new perspective for high-energy physicists on Earth.
Although the sun has accompanied the evolution of the entire life of the earth, humans did not understand the energy of the sun until the beginning of the last century. It originated from the nuclear fusion reaction of hydrogen at high temperature and pressure. Therefore, the history of human studies of the sun is notIt's a long time, and there are still a lot of mysteries waiting for scientists to solve the plasma fireball 150 million kilometers away.

Doctor's latest reminder: New crown virus may have new transmission channels, what must be paid attention to?In the course of fighting the epidemic, everyone's understanding of the new crown virus continued to deepen. A Shenzhen hospital detected positive viral RNA in the stool of confirmed patients. Experts believe that this suggests that the new coronavirus has the possibility of fecal-oral transmission.What should we pay attention to?Read 591027
