Chinese astronomers have discovered that the Milky Way is not a simple, smoothly warped disk, but contains widespread "wrinkle-like" structures resembling ripples on a water surface, providing new clues to understanding the galaxy's 3D structure and evolutionary history.
The discovery was made by a research team from the Purple Mountain Observatory (PMO) under the Chinese Academy of Sciences, using data from the "Milky Way Imaging Scroll Painting" (MWISP) survey. The findings were published online titled "Widespread corrugations superimposed on the Galactic warp in the outer CO disk" in the journal Nature Astronomy on August 7.
For decades, astronomers have known that the Milky Way's disk is not perfectly flat. Instead, its outer regions are slightly bent upward on one side and downward on the other - a structure known as a galactic warp.
However, the latest study shows that this large-scale bending is not the whole story. Smaller-scale vertical fluctuations are also embedded within the warped disk, creating a more complicated 3D structure.
"In many illustrations and in the public imagination, the Milky Way looks like a flat vinyl record," Sun Yan, associate researcher at PMO and the first author of the paper, told the Global Times on Tuesday. "In reality, the outer part of the Milky Way is more like a record that has been heated and deformed, with one side lifted and the other side lowered. That is the warp. On top of this large-scale deformation, there are additional smaller waves, which we call corrugations," Sun explained.
Using a more everyday analogy, Sun compared the Milky Way's structure to a sea surface. The warp is like a large swell that changes the overall height of the ocean, while corrugations are smaller waves superimposed on that swell.
"The two structures exist together. In our data analysis, we first removed the large-scale warp model, which allowed us to reveal the smaller wave-like patterns hidden underneath," Sun said.
The research focused on the Milky Way's outer gas disk rather than the more familiar stellar disk. According to Sun, cold molecular gas and stars provide two complementary ways to study the galaxy.
"Molecular gas is a sensitive probe for studying the vertical structure and dynamics of the galactic disk because it is concentrated near the disk plane and responds strongly to disturbances," she said.
Molecular gas is also the raw material for star formation, meaning its distribution is closely connected with the formation of young stars. The researchers traced this gas through carbon monoxide (CO) emission, which can penetrate regions obscured by interstellar dust and provide a different perspective from optical observations of stars.
The breakthrough was made possible by the MWISP survey, conducted using China's 13.7-meter millimeter-wave telescope. 
"MWISP can be understood as giving the Milky Way a large-scale medical examination using millimeter-wave observations," Sun said.
Previous CO surveys were limited in sensitivity and coverage, making it difficult to accurately study the distant outer regions of the galaxy. In contrast, the latest study identified more than 30,000 molecular cloud samples, covering about half of the Milky Way's outer disk and extending to a distance of about 26 kiloparsecs from the Galactic center.
With such a large dataset, researchers were able to first establish a model of the overall warp and then separate subtle structures from the background. The newly identified corrugations have radial wavelengths of about 3.9-7.9 kiloparsecs and vertical amplitudes of about 100-200 parsecs.
The study also identified a corrugation structure extending about 40 kiloparsecs in azimuth at a distance of around 12.7 kiloparsecs from the Galactic center. In some spiral arm regions, vertical displacements can reach approximately 200 parsecs.
The researchers believe these large-scale vertical fluctuations are likely related to "bending waves" triggered by external gravitational disturbances, suggesting that the Milky Way might have experienced more complex interactions during its evolutionary history.
Although the newly discovered structures sound dramatic, they do not have any direct impact on Earth or the solar system. "Humans cannot directly sense these corrugations," Sun said. "Their scales reach thousands or even tens of thousands of light-years, and even if these structures are evolving, such changes would not be directly perceptible on human timescales."
The study focuses on the outer disk of the Milky Way and does not include the region around the solar system. "There is currently no evidence that these structures have any observable influence on Earth's environment," Sun said.
Instead, their significance lies in what they reveal about the past. Like geological layers recording Earth's history, these galactic structures preserve traces of the Milky Way's evolutionary journey, the researchers explained.
Researchers said future studies combining more precise motion measurements and numerical simulations could further reveal the origins of these structures and their role in the long-term evolution of the Milky Way.
。越南队将在北京时间今晚21点坐镇河内美亭国家体育场迎战老对手泰国队，进行2026年东南亚锦标赛决赛次回合的较量。

C | 在22日于泰国曼谷进行的决赛首回合中，越南队以2-0获胜，次回合越南队只要不输两球及以上，便能捧起冠军奖杯。作为上届赛事冠军，越南队正冲击队史首次两连冠，这一成就连前任主帅朴恒绪也未曾做到。目前，金相植执教的越南队正保持着国际A级赛事25场连续不败的骄人战绩，是本届赛事最接近冠军的球队，正向历史纪录发起冲击。

D | 在25日举行的赛前新闻发布会上，金相植表示：“现在只剩最后一场比赛了。过去两个多月里，我们的球员一直在为这场决战而拼搏。这场决赛将是一场永载越南足球史册的比赛，我相信主角将是我们的球员。

E | ”我们将全力以赴，用精彩的表现给越南球迷带来巨大的喜悦与美好的回忆。希望球迷们能坐满美亭体育场，为球员们送上鼓励与助威。

F | ”金相植也向韩国球迷传递了心声：“我知道很多韩国球迷也在关注并支持越南足球。明天大家也会观看比赛，我们需要用快乐、精彩且胜利的足球来回报韩国球迷的喜爱。球员们近期表现也非常出色，我认为越南队未来有望在世界舞台上大放异彩，希望大家也能多多支持。” 首回合客场取胜让越南队距离奖杯更近一步，但金相植丝毫不敢掉以轻心。

G | 他表示：“首回合艰难的客场胜利让我们占据了有利位置，但实际上我们手里什么都还没有。”接着，金相植突然从座位上站起来说：“我的口袋里也什么都没有。为了实现夺冠目标、捧起渴望的奖杯，我们必须毫不松懈、全力以赴去争取胜利。”在随后的越南记者提问环节中，有记者提到了“跳舞庆祝”的话题。金相植回应道：“如果球员和球迷们希望看到，我非常乐意跳舞。希望我们的球员能够进球，然后我们一起跳舞庆祝。

H | ”在河内举行的决赛次回合较量早已一票难求。在可容纳逾4万人的美亭国家体育场外，比赛前一天便已有黄牛扎堆蹲守。主帅金相植坦言：“我也接到了许多求票的电话，看来现在不得不关机了。”说罢，金相植便真的将手机关机，以此表明自己将摒弃外界干扰，全心投入备战。最后，金相植表示：“过去两个多月里，球员们放弃了休假，告别挚爱家人，一心一意为球队备战这场决赛。”“到了决赛舞台，主帅的战术部署与精神激励固然重要，但更关键的是每位球员都要在心理上做好充分准备。这是至关重要的收官之战，但我们会一如既往地保持平常心，从容备战。
