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.

二 | 文中还提到了对 PlayStation 5 Pro 的支持，以及 Xbox Play Anywhere 和尚未明确的 Nintendo Switch 2 “专属特性”。
三 | 此版本将包含游戏的前两个资料片，而 The Witcher 3 的第三个资料片 Songs of the Past 也即将推出。
四 | 昨日已确认，Songs of the Past 将包含更多 巫师之昆特牌 内容，这是该系列中令人着迷的卡牌游戏。正如之前所确认的，今晚没有 巫师4 的消息——尽管这也在意料之中。
五 | 昨天，我们得到确认，这款备受期待、由希里主演的续作目标是在 2028 年发布，目前仍处于开发阶段。“我们 CD Projekt Red 总部的团队正在努力开发一个全新的传奇故事，由希里担任主角，”CD Projekt Red 联合首席执行官 Michał Nowakowski 此前表示。“我们有 500 多名才华横溢的开发人员致力于为您打造真正特别的作品。巫师4 拥有巨大且沉浸的开放世界、紧张且充满动作感的玩法，以及我们希望能在您心中长久留存的深刻且具有影响力的故事。简单来说，这是我们迄今为止规模最大、最大胆、最雄心勃勃的游戏。”“我知道大家很想知道它什么时候发布。这是我们一直被问到的问题。
六 | 虽然我们没有在活动中展示 巫师4，也没有准备好分享确切的日期，但我可以告诉大家：巫师4 的目标发布窗口是 2028 年。”“我知道这需要一段时间的等待，大家希望能早点玩到它，但请让团队继续磨炼。这段等待是值得的。在此之前，还会有更多 The Witcher 相关内容推出，包括将于 2027 年上线的 Songs of the Past。您可以确信，Gamescom 也在我们未来几年的计划之中。
