Its size is 1.5 times that of Jupiter… A gas giant with a density similar to cotton candy was found in outer space 1232 light years away from Earth. A gas giant with a density comparable to that of cotton candy was discovered in space 1232 light years away from Earth. Dubbed ‘WASP-193b’, the planet is 1.5 times larger in diameter than Jupiter, but has only one-seventh the mass (regarding 14%) of Jupiter. An international research team centered on the University of Liege in Belgium reported in a pre-published paper sharing collection that, as a result of analyzing the planet, the density is estimated to be 0.059g per cubic centimeter, similar to the density of 0.05g of cotton candy. This is regarding 1% of the Earth’s density, which is 5.51 grams per cubic centimeter. Jupiter, the largest gas planet in the solar system, has a density of 1.33 g. This is not the first time the so-called ‘cotton candy planet’ has been discovered. The first cotton candy planets discovered by astronomers were three planets in the Kepler 51 planetary system, identified in 2014. Analysis showed that the density of these planets at a distance of 2400 light-years from Earth was less than 0.1 gram per cubic centimeter. With an orbital period of 45 to 145 days and very close to the central star, these planets are believed to be composed mainly of hydrogen and helium. Discovered in 2019, the 212 light-year distance Virgo exoplanet ‘WASP-107 b’ is similar in size to Jupiter, but only one-tenth the mass of Jupiter. Until this time, astronomers thought that to be a gas planet the size of Jupiter, the planet’s core must be 10 times the mass of Earth to hold the gas. However, WASP-107 b’s core was found to be less than four times Earth’s mass, forcing us to revise our hypothesis. The newly discovered WASP-193b is 1.5 times larger than WASP-107 b. It is one of the largest cotton candy planets ever discovered. In addition, WASP-193b’s central star WASP-193 resembles the Sun in many ways. Above all, the mass is 1.1 times that of the sun, and the radius is also 1.2 times that of the sun, which is almost the same. In addition, the surface temperature of 1000 degrees and age of 6 billion years is not much different from the surface temperature of the sun of 1500 degrees and age of 4.6 billion years. In order for a celestial body with the density of cotton candy to be maintained, several conditions must be well matched. Provided by the University of Colorado Boulder Difficult to explain with existing planetary evolution models How did WASP-193b become a fluffy cotton candy planet? First of all, the fact that it is close to the stars can be cited as one factor. WASP-193b is closer to its central star than any other planet in the solar system. At a distance of only 10 million km from the star, it orbits the star every 6.25 days. Closer to the star, the atmosphere heats up and expands. This is especially true if the atmosphere is composed of the lightest elements, hydrogen and helium. This period doesn’t last very long. This is because the heat and stellar winds ejected from the stars blow away the planet’s atmosphere. Scientists believe that this condition might last for tens of millions of years at most. However, the problem is that the age of this star is estimated to be up to 6 billion years. It is difficult to explain with existing planetary evolution models. The researchers plan to focus future observations on solving this enigma. The research team said, “This planet is a very good observation candidate for the James Webb Space Telescope, which is taking analysis of the atmosphere of exoplanets as a major scientific mission.” Senior Reporter Kwak Nopil [email protected]

Fencing rules require a handshake at the end of the match.

At the world fencing championships, a Ukrainian athlete refused to shake hands with a warring Russian athlete and was disqualified even following winning. According to foreign media such as (AFP) and (BBC) on the 27th (local time), Ukraine’s Olga Harlan and Russia’s Anna Smirnova met in the Saber Round of 64 at the Fencing World Championships held in Milan, Italy. The win or loss was 15-7 and returned to Harlan’s victory. Harlan is a leading Ukrainian fencing player who has won many international competitions. Russia has been subject to sanctions such as banning participation in various international sports events due to the invasion of Ukraine, but Smirnova competed as an individual member of a neutral country, not as a national representative. The International Fencing Federation (FIE) granted this qualification to 17 players from Russia in May.

The problem arose following the game was over. After the match, Smirnova asked Harlan to shake hands, but Harlan held out her fencing sword and left the piste (fencing platform) without shaking hands. Smirnova sat for a long while in a chair on her piste, as if expressing her protest at the situation. The Guardian said Smirnova sat for 50 minutes. The rules of the International Fencing Federation specify that the two players should shake hands following the match results are out, but in the end, Harlan was disqualified following receiving a ‘black card’ (exit order) for unsportsmanlike behavior. Harlan told reporters at the scene that “the FIE president assured me that it is possible to touch the sword instead of shaking hands”. I’m not going to shake hands with them,” he said. Archyde.com said in a video that Harlan posted on his social network service (SNS) that day, “Today was a very difficult and very important day. What happened today raises a lot of questions,” he said. “I don’t want to shake hands with that player. So when he heard that he was disqualifying me, he screamed in pain.” “People need to understand that the rules have to change because the world is changing,” he said.

The Ukrainian government protested that the disqualification should be withdrawn. Ukrainian Foreign Minister Dmitro Kuleva told X (X, old Twitter), “Harlan competed fairly and won. We urge the FIE to restore his rights and allow him to continue competing.” The Ukrainian Fencing Federation is also considering a response. Elina Svitolina, who previously refused to shake hands with players from Russia and Belarus at the ‘2023 Wimbledon Championships’, an international tennis tournament, said, “She did the right thing for the people,” and she did not support Harlan’s actions. told Reporter Seungjun Lee [email protected]

Russia has said it will no longer extend the Black Sea grain export agreement, which has ensured the safe operation of cargo ships exporting grain through Ukraine. If grain export routes through the Black Sea are blocked, low-income countries in Africa and the Middle East, which have been importing wheat and corn from Ukraine, are expected to suffer food shortages. Dmitry Peskov, a spokesman for the Russian Kremlin (Presidential Palace), said on the 17th (local time) that the grain agreement, which expires on the 18th, will not be extended, news outlets reported. Peskov spokesman said at a press briefing that day, “The agreement has effectively ended today. “The grain agreement is over,” he said. “If Russia’s demands are implemented, Russia will immediately return to the agreement.” Russia’s announcement came hours following two people were killed in an attack on the Crimean Bridge connecting the Russian mainland and the Crimean Peninsula. Russian President Vladimir Putin also said in a phone call with South African President Cyril Ramaphosa on the 15th that the grain agreement might not be extended, saying that the conditions for extending the grain agreement were not met. After Russia announced its intention to terminate the agreement, wheat prices soared by around 4 percent on the Chicago Mercantile Exchange. Russia and Ukraine signed an agreement on July 22 of last year to guarantee exports of grain from Ukraine through the Black Sea through the mediation of the United Nations and Turkey as food shortages broke out in the Middle East and Africa following the war began at the end of February last year. This agreement has since been extended three times, and the deadline for the third extension was on the 17th. Whenever the agreement was extended, Russia has complained that the plan to promote Russian grain and fertilizer exports agreed between Russia and the United Nations is not being implemented. In March, the deadline for the agreement was cut in half from 120 days to 60 days. The West has refuted this, saying that Russia’s exports of grain and fertilizer are not disrupted. According to U.S. Department of Agriculture statistics, Russian wheat export shipments hit 45.5 million tons in fiscal year 2022-2023, and are expected to rise to 47.5 million tons in 2023-2024. After the grain agreement was concluded, Ukraine has exported 32.9 million tons of grain through three Black Sea ports including Odessa. The Food and Agriculture Organization of the United Nations said this would account for half of the food needs of 45 developing countries. Grain exports through the Black Sea peaked at 4.2 million tons in October last year, but fell steadily to 1.3 million tons in May. Before the war, Ukraine’s wheat and corn exports accounted for 10% of world total. Senior Reporter Jeong Eui-gil [email protected]

Revealing the Truth: The Most Popular Food Additives in Russia That Don’t Benefit Your Health
written by Alexandra Hartman Editor-in-Chief
2023-07-16 07:35:01
Most popular food additives among Russians do not have a positive impact on health.
Waste
In the family budget of many families there is a special item of expenditure – for vitamins. Taking dietary supplements has become as natural and habitual as brushing your teeth in the morning. For the sake of improving health, people do not spare money for the purchase of vitamin complexes. However, according to nutritionist Anastasia Solchnova, not all drugs have the characteristics stated on the package.
The expert listed the most popular “pacifiers” among the people.
Multivitamin complexes. They are usually bought to save money. Like, for one price, 5-10 useful trace elements at once. Alas, a miracle does not happen: a positive effect from them cannot be expected in the foreseeable future. It is easy to check this – just take a blood test for a number of trace elements.
Dietary supplements that give youth and slow down aging. All the promises of manufacturers regarding getting rid of toxins, improving skin elasticity, improving blood circulation and other changes are a complete myth. Even certified medicines cannot cope with such a voluminous task. And BADam – even more so. if you want to live longer and look good at the same time – eat less, give up bad habits and make friends with sports.
Vitamin D tablets. It is very poorly absorbed in this form. It is much more efficient to replenish supplies by walking in the fresh air and increasing servings of seafood, sea fish, eggs and other foods that definitely have vitamin D and are well absorbed.
Omega 3. As a rule, these are the most expensive dietary supplements in pharmacies. However, is it worth spending a lot of money if you can find fatty acids not only in expensive salmon, but also in ordinary herring, nuts, avocados, vegetable sunflower oil?
Vitamin C. Another myth on which people spend large amounts every month. Getting vitamin C from foods is easy: eat citrus fruits, as well as sauerkraut and bell peppers. They are tasty, healthy and are much cheaper than bright packages of incomprehensible dietary supplements.
