📌 MAROKO133 Breaking ai: The Milky Way has a Colossal Wave Rippling Through It, As

The Milky Way galaxy is like a gigantic ocean gyre or eddy that spins and wobbles around its center.

But our home galaxy also has a colossal wave rippling through it, pulling and pushing an ocean of stars and cosmic dust in its wake, according to newly released images from the European Space Agency’s Gaia space telescope.

The images show that this wave of motion emanates from the center of the Milky Way and takes up a large portion — a little less than half — of the galaxy’s entire body, which itself is warped in the outer edges. Looking at the galaxy in a vertical sideways view, you see that stars float above or below the disc’s dusty central body, as if they were fish bobbing up and down in a wave of water after a boat passes by.

The new images, publicly disseminated on Tuesday by the European Space Agency, are based on a study by European and American scientists published in the journal Astronomy & Astrophysics earlier this year; more discoveries are forthcoming in the future as astronomers continuously examine data from Gaia, which ceased operations earlier this year.

“The intriguing part is not only the visual appearance of the wave structure in 3D space, but also its wave-like behavior when we analyze the motions of the stars within it,” said Eloisa Poggio, an astronomer at Italy’s Istituto Nazionale di Astrofisica and first author of the study, in a statement about the research.

The scientists detected this pattern after analyzing the position and velocity of more than 20,000 young stars and saw that these glittering bodies “exhibit both radial and vertical systematic motions,” reads the study. They are caught in a wave of motion that spans 30 to 65 thousand light years of spacetime real estate, while rippling away from the Milky Way’s nucleus.

The scientists are not sure what’s causing this wave pattern to manifest, but a possible explanation is that a dwarf galaxy either passed by or was devoured by our much larger galaxy in the past, leaving traces of this violent encounter in the wave formation, according to the study. Previous simulations of this cannibalistic scenario affirms that this could result in a wave pattern.

Another possible explanation is that this wave is somehow connected to the Radcliffe Wave, a gaseous region of the Milky Way that’s about 500 light years away from our solar system, but the scientists in the study said they are likely not connected because Radcliffe is smaller and is located in a different part of the galaxy from the big wave.

Analysis of additional data from the Gaia telescope and others may yield reasons why the galaxy has this intriguing wave pattern; whatever the reason, each research project brings us deeper understanding of the glittering and mysterious Milky Way, our cosmic home.

📌 MAROKO133 Eksklusif ai: Robot that reads wind direction, offers accuracy compete

Spectators witnessed a unique showdown: South Korea’s elite archers facing off against Hyundai Motor Group’s cutting-edge shooting robot.

The face-off happened during the 2025 Hyundai Motor Chung Mong-koo Cup Korea Archery Championship that happened on October 3.

The robot is fitted with sensors to read wind direction and speed, adjusts its launch angles with millimeter accuracy. During the competition, after a storm, it recalibrated and delivered a streak of perfect 10s, but still fell short of the national team by a single point.

Adding to the spectacle, Spot, the robot dog from Boston Dynamics—Hyundai’s robotics affiliate—took on the role of transporting arrows during the competition.

Archery’s tech duel

Despite heavy rain sweeping across Gwangju’s famous 5·18 Democracy Square in South Korea, spectators stayed on to witness an extraordinary exhibition at the 2025 Hyundai Motor Chung Mong-koo Cup Korea Archery Championship.

The much-anticipated highlight was a “clash of the century” that pitted South Korea’s elite national archers against a state-of-the-art shooting robot developed by Hyundai.

According to Chosun, equipped with advanced sensors, the robot continuously measured wind direction and speed, adjusting its shots with millimeter-level accuracy. A sudden downpour initially disrupted its performance, but after recalibration, it delivered a streak of perfect 10s. Even so, the human competitors proved stronger under pressure. The men’s team—Kim Woo-jin, Lee Woo-seok, and Kim Je-deok—joined forces with the women’s trio—An San, Kang Chae-young, and Lim Si-hyeon—to outscore the robot by the slimmest of margins, 55 to 54.

In the compound bow category, the national team again displayed remarkable consistency, with all six archers hitting 10-point targets to surpass the robot’s 58 points. Adding to the show, Boston Dynamics’ robot dog Spot, operated by Hyundai’s robotics affiliate, played a supporting role by transporting arrows, reports Donga.

The event was designed to mirror the conditions of international tournaments, from venue layout to athlete movement routes, giving domestic archers a setting comparable to global competitions. It also doubled as a test of South Korea’s preparedness ahead of the 2026 Aichi-Nagoya Asian Games next September and the 2028 Los Angeles Olympics.

Robotics refines archery

Hyundai, a long-time supporter of South Korea’s national archery team since 1985, has introduced advanced robotics and engineering tools to enhance training and performance.

In 2024, the company unveiled the self-adjusting archery robot capable of firing arrows with such precision that identical shots can be reproduced repeatedly, allowing athletes to sharpen their skills. This robot can adjust its launch angle and intensity, while also identifying defective arrows.

To further aid performance, Hyundai has introduced a multi-camera posture analysis system that records athletes from unique angles, including overhead and front views, providing detailed insights for posture correction and training.

In addition, the company has applied 3D printing to create custom bow grips, tailored to each archer’s hand shape with ultra-fine accuracy, enabling greater comfort and unifying the bow with the athlete’s grip. These customised grips are already in use by South Korea’s archery team during competitions.

Another innovation is a camera-based heart rate sensor that detects subtle skin colour changes to measure blood flow. Capable of monitoring athletes from more than 10 meters away, it allows stress-free, unobtrusive tracking of heart rates during training, with the potential to display real-time data to audiences during major sporting events.

South Korea’s archery team had made a clean sweep at the 2024 Olympic Games in Paris, grabbing gold in all five men’s and women’s competition categories.
