On December 25, UPI’s website reviewed five shocking scientific breakthroughs and discoveries related to space in 2020, as follows: < / P > < p > it is reported that scientists have a deep understanding of the internal operation of the sun, but there are still many questions about this star, such as why its atmosphere is hotter than its surface and why the coronal mass is thrown away Why does shooting start. < / P > < p > in 2020, scientists have studied some of the most puzzling phenomena of the sun more carefully, thanks to two astronomical observatories: NASA’s high-resolution coronal imager, which is a suborbital telescope, or Hi-C for short; NASA’s solar orbiter, which is a space probe jointly managed by the agency and the European Space Agency. < / P > < p > this spring, scientists on the Hi-C mission released the clearest picture of the sun ever, revealing the fine lines of the epithermal plasma that make up the outer layer of the sun. NASA and European Space Agency researchers, who are responsible for the observation of the solar orbiter, are not lagging behind. They have released the most recent pictures of the sun so far. “These amazing images will help scientists understand what the sun’s atmosphere looks like,” Holly Gilbert, a scientist at NASA’s Goddard Space Center, said in a press release It is reported that in 2020, researchers will publish the first scientific research paper based on the data collected by NASA insight. Since the beginning of scientific research mission at the end of 2018, the seismograph on insight has detected hundreds of Mars earthquakes. “Insight” instruments frequently detected seismic waves, indicating that the landing location of a few feet below the surface is a large area of sand. < / P > < p > according to the analysis of researchers from NASA and the Federal Polytechnic University in Zurich, the composition under the Martian sandy topsoil is similar to the crystalline crust of the earth, but there are more cracks. Researchers have linked some of Mars’s earthquakes to a volcanic active area called the seebler trough, which contains two deep trenches formed by lava flows about 10 million years ago. “It’s almost the youngest structural feature on the planet,” Matt golonbeck, a planetary geologist at NASA’s Jet Propulsion Laboratory, said in a press release. The fact that we see signs of earthquakes in this area is not surprising, but it’s really great. ” According to the report, the exploration of life continues to dominate the field of planetary science. It has inspired all kinds of scientists from geochemists to astrobiologists to carry out a series of research, but it also focuses on the endless pursuit of outer star water. < / P > < p > this summer, NASA scientists used complex mathematical models to predict whether there is water on earth like planets near the solar system. Linda quack, a planetary scientist at Goddard Space Center, found that a quarter of the 53 exoplanets they analyzed are likely to have oceans. That means they have huge bodies of water wrapped in ice, like Saturn’s moon Enceladus and Jupiter’s moon Europa. “The next space mission will give us a chance to see if the satellites with oceans in the solar system can support life,” quack said in a NASA press release < / P > < p > researchers believe that more than a dozen exoplanets may exist in the same underground ocean as Enceladus. This is a picture of Enceladus. < / P > < p > last year, China became the first space country to deliver spacecraft to the back of the moon. It is the first month of this year to collect rock samples from the earth and send them back to China. In early December this year, China’s chang’e-5 lander landed on Mount lumuke in the northern part of the frontal storm ocean of the moon, with a history of 1.2 billion years. After collecting 4.4 pounds of lunar rock and lunar soil samples, the lander launched from the lunar surface and rendezvous with the spacecraft’s orbiter. Chang’e-5 capsule separated from the main spacecraft about 3000 miles above the South Atlantic Ocean and landed in Inner Mongolia on December 17. At the beginning of October, NASA’s “Pluto” probe completed the mobile sampling immediately after landing during its flight around the “Benu” asteroid. < / P > < p > the rock sample was successfully sealed in a capsule ready to go home. The journey back to earth will begin next year, but rock samples are not expected to land until 2023. < / P > < p > scientists hope that these samples will help them decipher the early history of the solar system and help Planetary Defense engineers protect the earth from asteroids. < p > < p > while NASA is waiting for its own asteroid rocks to return, the Japanese space agency announced that its asteroid sampling and return mission – “falcon 2” asteroid probe has achieved success. In early December, the Japanese aerospace research and development agency successfully recovered the capsule carrying rock samples from the asteroid “Dragon Palace” and deep space gas. gather and watch!
