武汉夜生活027

At nearly 30 hours and 20,000 kilometers away from Beijing, Buenos Aires in Argentina is one of the furthest destinations in the world from the Chinese capital. In a popular 2024 stand-up comedy show, Yan Hexiang, a Chinese actor and crosstalk performer, humorously pointed out that the antipodal point to Beijing is located in the Pampas grasslands of Argentina. However, the distance between Argentina and China doesn't seem so far. Just about 38 kilometers from Ministro Pistarini International Airport in Buenos Aires, is a largely commercial section about five blocks long in the district of Belgrano, where a towering Chinese-style archway greets you, inscribed with the words "China Town."

The Global Times has visited many "Chinatowns" around the world, including those in Washington, London, and Nagasaki. However, Buenos Aires' "Chinatown" is quite different from the rest. This is immediately apparent upon entry: On a Sunday evening, the streets bustle with activity, restaurants have long wait times, and shops attend to numerous customers. Upon closer inspection, the Global Times noticed that non-Chinese diners and shoppers actually outnumber Chinese ones.

In Chinese, the word "foreigner" is used to refer to anyone who is not Chinese, therefore within the context of Buenos Aires, it is used to refer to non-Chinese locals. In many other "Chinatowns" in the world, Chinese nationals are surrounded by their own, and while the occasional less-than-authentic Chinese cuisine might remind them that "this is not China," the presence of Chinese nationals gives a sense of belonging. In contrast, in Buenos Aires' "Chinatown," surrounded by countless local faces, the "Chinese nationals" seem more like visitors passing through.

Famous Chinese hotpot restaurant brands like Little Sheep Mongolian Hot Pot, Shoo Loong Kan Hot Pot, and Haidilao Hot Pot, commonly found in American "Chinatowns," are conspicuously absent. However, Chinese culture, cuisine, and products are everywhere, and even bubble tea has become a favorite among the youth in the "Chinatown." A capybara in a shop window observes the comings and goings, much like its counterpart in the trendy toy area of Chaoyang district's Joy City mall in Beijing, 20,000 kilometers away.
In addition to Chinese elements, graffiti in the style of Japanese animator, filmmaker, and manga artist Hayao Miyazaki features the Chinese characters for "Visited Here," and posters of South Korean idols appear in shop windows, indicating that this "Chinatown" not only spreads Chinese culture but also incorporates East Asian elements. A few steps further, a street magician interacts with the audience, with a prominent image of "Guanyin" on the wall behind him, as if everything before us is being witnessed by the bodhisattva.
Why are there so many "foreigners" in Buenos Aires' "Chinatown"? Locals provided various answers. Most people's first response was that "Chinatown" is an important social media hotspot in Buenos Aires. If you plan a day trip to the city, this is a must-visit location. "You visited on the last day of a long weekend, so of course, there were many people shopping and dining; people love going to Chinatown," a local Chinese national told the Global Times.

Another local explained that unlike many other "Chinatowns," Buenos Aires' "Chinatown" has a significant number of Chinese residents, but it is not the main gathering place for the local Chinese community. With its trendy atmosphere, it naturally attracts a lot of young people, making the "foreigners" seem particularly popular.

What is it that attracts so many "foreigners" to this "Chinatown"? "Chinese cuisine" topped the list of mentions, with Chinese products and culture also frequently cited among those interviewed by the Global Times. "Yufu" is a relatively authentic Cantonese restaurant in Buenos Aires' "Chinatown," where Chinese food is on the pricier side compared to local dining options. Yet even at 2:10 pm on Sunday, the restaurant was still packed, and the number of Chinese diners was visibly less than half of all patrons.

"Exquisite, compact, and easy to explore," said Nora, director of a research company in Buenos Aires, when asked about the "Chinatown". She added, "I love the dim sum in 'Chinatown'; I enjoy the exotic atmosphere there. The shop owners are very friendly, and the products are diverse; you can find many things you want in one store."

Liu Jialong, a 19-year-old local of Chinese descent, told the Global Times that "Buenos Aires also has a 'Koreantown,' which is only one street and much smaller than 'Chinatown.' It used to be very popular, but its popularity has declined. In contrast, 'Chinatown' is booming now."

If China were not becoming stronger and developing so rapidly, would people be increasingly interested in China? he asked.

On the diplomatic front, the Milei administration made some comments about China that were deemed newsworthy by some Western media outlets before taking office. However, Argentines, including scholars and businesspeople, that the Global Times reporter met here during the trip place great importance on China-Argentina relations. China is Latin America's second-largest trading partner and holds the top position in several countries. In a recent survey released by the Global Times Institute (GTI), in collaboration with the Latin American Council of Social Sciences (CLACSO) and the China-Latin America Education and Culture Center, on the "China-LAC mutual perception" conducted in both regions found that the most prominent impression left by China on Latin Americans was "technology." When asked to fill in keywords that represent their primary impressions of China, a Gen Z respondent from Argentina mentioned "DeepSeek."
Of all those interviewed by the Global Times, Wu Ditai, a young Argentine scholar who studied at Peking University, was the most knowledgeable about China. Watching him mimic the distinct drawl common among Beijing's taxi drivers was as impressive as it was comedic.

"It's not just 'Chinatown'; if you look deeper, Argentines are very curious about China. They want to know why China is developing so quickly and what experiences Argentina can learn from," Wu Ditai said. He has plans to return to China soon and hopes to travel across all provinces to gain a deeper understanding of the country.

Of course, the reality is that many Argentines do not have a sufficient understanding of China. Most of their information comes from the media, especially Western media sources and social media.

An Argentine journalist told the Global Times that while there is considerable coverage of China in local media, the current lack of understanding among Argentines about China is unlikely to change in the short term.

"'China Travel' is a trending topic now, and Argentina has visa-free access. The real China is right there, and everyone is welcomed to learn about it," the Global Times told Wu Ditai.

The nucleus of a comet discovered in 2014 is the largest ever spotted.

The “dirty snowball” at the center of comet C/2014 UN271 is about 120 kilometers across, researchers report in the April 10 Astrophysical Journal Letters. That makes this comet — also known as Bernardinelli-Bernstein, after its discoverers — about twice as wide as Rhode Island, says David Jewitt, an astronomer at UCLA.

Though the comet is big — and vastly larger than Halley’s comet, which measures a little more than 11 kilometers across — it will never be visible to the naked eye from Earth because it’s too far away, Jewitt says (SN: 12/14/15). The object is now about 3 billion kilometers from Earth. At its closest approach in 2031, the comet will come no closer to the sun than 1.6 billion kilometers, about the same distance as Saturn.
Jewitt and colleagues sized up the comet with the help of new images from the Hubble Space Telescope, combined with images taken by another team at far-infrared wavelengths. The analysis also revealed that the comet’s nucleus reflects only about 3 percent of the light that strikes it. That makes the object “blacker than coal,” Jewitt says.

Comet Bernardinelli-Bernstein takes about 3 million years to circle the sun in a highly elliptical orbit. At its farthest, the comet may reach about half a light-year from the sun — about one-eighth of the distance to the next nearest star.

The comet is likely “just the tip of the iceberg” as far as undiscovered comets of this size go, Jewitt says. And for every comet this size, he suggests, there could be tens of thousands of smaller objects circling the sun undetected.

Two mysterious galaxies, devoid of dark matter, could have a smashing origin story.

About 8 billion years ago, researchers propose, two dwarf galaxies slammed into one another. That cosmic crash caused the gas within those two galaxies to split up and form multiple new dwarf galaxies, including the two dark matter–free ones.

A newfound row of dwarf galaxies, more than 6 million light-years long, could have formed in the aftermath of the hypothesized crash, researchers report in the May 19 Nature. If correct, the finding could help solve the mystery of how such unusual dark matter–free galaxies form, and reveal new details about the nature of dark matter.

But other scientists are skeptical that there’s enough evidence to support this backstory. “If this is true, I think it would be really exciting. I just don’t think the bar has been met,” says astronomer Michelle Collins of the University of Surrey in Guildford, England.

In 2018, Yale University astronomer Pieter van Dokkum and colleagues reported a dwarf galaxy with no dark matter (SN: 3/28/18). The invisible, mysterious substance is typically detectable in galaxies via its gravitational effects on stars. When a second dark matter–free dwarf galaxy was found in the vicinity in 2019, it raised an obvious question: How did the two oddball galaxies form? Dark matter is generally thought to form the foundation of all galaxies, gravitationally attracting the gas that eventually forms stars. So some process must have separated the dark matter from the galaxies’ gas.

Scientists have previously seen dark matter and normal matter separate on a very large scale in the Bullet Cluster, which formed when two clusters of galaxies rammed into one another (SN: 8/23/06). Other researchers had proposed that something similar might happen with colliding dwarf galaxies, what van Dokkum and colleagues call “bullet dwarfs.”

In such a collision, the dwarf galaxies’ ethereal dark matter would continue on unperturbed, because the dark matter doesn’t interact with other matter. But the gas from the two galaxies would slam together, eventually forming multiple clumps that would each become its own galaxy, free of dark matter.

Now, van Dokkum and colleagues say that the bullet dwarf idea explains the two previously reported dark matter–free galaxies — and several other galaxies nearby. The two galaxies are moving away from each other as if they had come from the same spot, the researchers say. What’s more, the two galaxies are part of a chain of 11 galaxies aligned in a row, a structure that could have formed in the aftermath of a bullet dwarf collision.
“It’s super satisfying to finally have an explanation for these weird objects,” van Dokkum says.

But, Collins says, “there could be much more done to make it convincing.” For example, she says, the scientists didn’t measure the distances of all the galaxies from Earth. That means some of the galaxies could be much farther away than others, and it could be a coincidence that the galaxies appear to be lined up from our viewpoint.

And the researchers haven’t yet measured the velocities of all the galaxies in the trail or determined whether those galaxies are also missing their dark matter, which would help confirm whether the scenario is correct.

Other scientists are more optimistic. “The origin story is very plausible in my opinion,” says astrophysicist Eun-jin Shin of Seoul National University in South Korea. Shin cowrote a perspective article on the discovery with astrophysicist Ji-hoon Kim, also of Seoul National University, that was also published in Nature.

Computer simulations performed by Shin, Kim and others have shown that bullet dwarfs can produce such dark matter–free galaxies. If confirmed, the bullet dwarf idea could help pin down dark matter’s properties, in particular whether dark matter interacts with itself (SN: 4/5/18).

Van Dokkum and colleagues are planning additional measurements that could confirm or refute the case. But so far, he says, “It has, to me, the ring of truth.”
