The TESS satellite, which is searching for planets outside the Solar System, has discovered an unknown dusty object orbiting a star. The source of radiation, periodically losing brightness due to strange dust, scientists noticed by chance. It was named TIC400799224, according to the Harvard-Smithsonian Center for Astrophysics. The brightness drop of TIC400799224 by almost 25% occurred very quickly — within just four hours. After observing, scientists soon noticed several more sharp changes in brightness, each of which could be interpreted as a kind of eclipse. Astronomers have concluded that TIC400799224 is probably a binary star system in which one of the stars pulsates with a period of 19.77 days. But the nature of the orbiting object, which emits clouds of dust obscuring the binary star, is puzzling to researchers. Usually, dust clouds are released by a decaying planet or a smaller object, for example, an asteroid. But the volumes of

In September, Director of the Russian Direct Investment Fund (RDIF) Vladimir Primak announced the start of bottling of the Sputnik Lite vaccine in Armenia. He noted that the drug will become available to the public after passing quality control. “The coronavirus vaccines available in Armenia have been replenished with the Sputnik Light drug, which in Armenia is intended to be used only for vaccination with a booster dose,” the message received by RIA Novosti reads. It is noted that citizens over the age of 18 will be able to get vaccinated with the Sputnik Lite vaccine. In Armenia, according to the Ministry of Health, as of December 30, 345,126 cases of COVID-19 infection were confirmed, 7986 people died. As part of the fight against COVID-19, quarantine has been declared in the country until June 20, 2022. The total population of the republic exceeds 2.9 million people.

The Chinese automatic interplanetary station “Tianwen-1” has sent new images of Mars, including the first full photo of the orbiter of the mission. The color photographs show the spacecraft flying in orbit around the Red Planet, the ice cover at the north pole of Mars and the spectacular landscape on the barren Martian plain. The photo of the probe, which is now about 350 million kilometers from Earth, was taken using a camera released by the apparatus, the National Space Administration of China said in a statement. Launched in July 2020 from the Wenchang Cosmodrome in Hainan Province, the Tianwen-1 robotic probe, named after an ancient Chinese poem, traveled a total of 475 million kilometers and performed several trajectory maneuvers before entering Martian orbit on February 10, 2021. After more than three months of preparation, the landing capsule released by the probe landed on the Red Planet on May 15.

People on Nastasya’s day were preparing for Christmas and watching the weather. It was thought that the weather on January 4 would be the same in October. The water level has dropped in the rivers — the summer will be dry. We watched the clouds: if they go against the wind, it will snow soon. Birds in flight make more noise with their wings than usual — they anticipate bad weather. During sunset, the sky is clear — the next day will be clear and sunny.

Per day in 834 patients died in Russia, which is less than yesterday (835). The total number of deaths reached 312,187. 24,037 people recovered during the day, a total of 9,575,147 people. Regions are leaders in the number of new cases: Moscow — 1335 (for all time – 2,036,375), Saint Petersburg – 1331 (856 251), Moscow region — 1180 (645,259), Sverdlovsk and Chelyabinsk regions – 445 each (200 040 and 146 573), Krasnodar Territory — 432 (119 993). Regions-leaders in the number of deaths: Moscow – 70 (since the beginning of the pandemic — 36,977), Saint Petersburg – 55 (28,204), Moscow region – 43 (12,235), Krasnoyarsk Territory — 37 (8,726), Nizhny Novgorod region — 29 (9,874). Earlier, Rospotrebnadzor said that they expect the situation with COVID-19 to worsen after the New Year. The head of the department, Anna Popova, noted that Russia is approaching the new year with a stabilizing coronavirus

According to the Forbes Real-Time list of billionaires updated in real time, Musk’s fortune increased by $ 32.6 billion per day and amounted to $ 304.2 billion. Thus, he continues to maintain leadership in the ranking of world billionaires. In November 2021, when Tesla stock prices updated the historical record, Musk became the first person in history whose fortune reached $ 300 billion. Last October, he became the richest man in the history of Forbes calculations with a fortune of $ 257.6 billion. Before that, Amazon founder Jeff Bezos was considered the person with the largest fortune in history — his wealth reached the $212 billion mark. Even more interesting things about people

“Clearly, in order to interpret the dependence of life on coronavirus infection, you need to have a fairly serious statistical basis for such statements. And today it is somewhat premature,” Associate professor of the Department of Infectious Diseases of the RUDN Sergey Voznesensky told RBC. “Too little time has passed [since the beginning of the pandemic] for us to assess life expectancy and how it has been affected by the disease people have suffered. Probably, we can talk about some forecasts,” Alexey Agranovsky added. So far, all the data suggest that coronavirus infection refers to “acute respiratory diseases, which in the vast majority of cases pass without a trace,” Voznesensky said. Here it is necessary to look at the fact that the coronavirus is often superimposed on any pathology that a person used to have. “For example, some pathologies of the vascular system in people who have had a coronavirus

“We are still working. In next year. We need to carry out all the tests so that it is safe, first of all, and effective,” he said. Chemezov added that there are already good research results, but there are things that still need to be finalized. Vaccination remains the most reliable way to protect against COVID-19. According to the head of the Russian Ministry of Health Mikhail Murashko, the proportion of vaccinated among those infected with coronavirus does not exceed four percent. Vaccination can be done in any Russian region. In August last year, the Ministry of Health registered Sputnik V— the world’s first drug for the prevention of COVID-19, developed by the Gamalei Research and Development Center. Also in Russia has created the vaccines “EpiVacCorona” from the Vector Center of Rospotrebnadzor and “KoviVak” from the Chumakov Center of the Russian Academy of Sciences. At the beginning of May 2021, it

“We will see a significant improvement in the situation in 2023,” he said. Voznesensky noted that in order to end the pandemic, in addition to the medical problem, financial, economic, and geopolitical issues must be stabilized. Vaccination remains the most reliable way to protect against COVID-19. According to the head of the Russian Ministry of Health Mikhail Murashko, the proportion of vaccinated among those infected with coronavirus does not exceed four percent. Vaccination can be done in any Russian region.

The processes taking place in the Pacific Ocean will lead to the fact that the air temperature in the world in 2022 will be lower than in 2020, and about the same as in 2021, he believes. “I am speaking on the basis of the fact that the phenomenon of La Niña is developing in the vast territory of the Pacific Ocean (the water surface is getting colder due to strong winds, which affects the climate. – Editor’s note), which means that an increased flow of heat will be directed from the atmosphere to the ocean,” Kokorin predicts. In 2022, the inhabitants of the Earth will face abnormal temperature changes and uneven precipitation falling in different periods of the year, the expert continued. “The long-term trend towards the formation of unstable and nervous weather will continue. That is, sharp temperature changes in 2022 will continue, as well as large-scale precipitation
