Satellite imagery has confirmed that China’s newest aircraft carrier remains stationed at its naval base in Qingdao, contradicting a recent social media claim that the vessel had deployed to waters near Taiwan. The European Space Agency’s Sentinel-2 satellites captured images showing the 1,036-foot ship docked far to the north, refuting assertions by a military-focused X account that the Fujian and its carrier group had moved into the Taiwan Strait. The claim, which garnered over 91,000 views, sparked mixed reactions online. Some users viewed the assertion as plausible, citing U.S. military actions in the Middle East as a potential context for China’s movements. Others dismissed the post as speculative or fake news. Meanwhile, analysts emphasized the need for caution in interpreting short-term military activity. Ben Lewis, an independent defense analyst and co-founder of PLA Tracker, warned against drawing firm conclusions from fleeting changes in military operations. China’s military has intensified pressure on Taiwan in recent years, with frequent flights over the Taiwan Strait’s median line and simulated blockades. A deployment of an aircraft carrier near Taiwan’s coast would represent a significant escalation, though the satellite evidence suggests no such movement has occurred. The claim emerged amid renewed speculation about China’s military activity following a brief lull in PLA Air Force flights into Taiwan’s air defense identification zone. Flights resumed last week at a reduced pace, with none reported on Monday. Taiwan’s Defense Ministry confirmed that 28 PLA aircraft, including fighter jets and an early warning aircraft, were tracked in the Taiwan Strait on Tuesday.#european_space_agency #people_s_republic_of_china #sentinel_2 #fujian #taiwan_strait
NASA accidentally altered an asteroid’s solar orbit during its 2022 DART mission, marking the first time humanity has changed an asteroid’s path around the sun. A new study reveals that the mission’s impact on the moonlet Dimorphos also shifted the trajectory of its parent asteroid, Didymos. The DART mission, designed to test planetary defense by altering an asteroid’s path, targeted Dimorphos, a 525-foot-long moonlet orbiting the 2,550-foot-long asteroid Didymos. Neither object posed a threat to Earth, but the experiment aimed to demonstrate how a spacecraft could nudge an asteroid away from a potential collision. The mission succeeded in shifting Dimorphos’s orbit around Didymos by 33 minutes, far exceeding the 73-second target. However, the force of the impact also caused Didymos to move slightly along its solar path. Researchers explain that the collision’s energy disrupted Dimorphos, a rubble-pile asteroid, releasing debris that acted like a rocket’s jet, propelling Didymos backward. While the change in Didymos’s orbit was minuscule—equivalent to moving the asteroid the length of the Eiffel Tower over a year—the discovery highlights the unintended consequences of planetary defense experiments. Astronomers used stellar occultation observations to track the asteroid pair’s movement, finding that Didymos’s speed decreased by 22 millionths of a mile per hour. Though the shift was tiny, it underscores how even subtle changes in asteroid trajectories can accumulate over time. The study’s authors emphasize that the Didymos system remains safely distant from Earth, posing no immediate threat. The findings also provide insights into asteroid density. Dimorphos, with a density similar to water, behaved like a fluid during the impact, while Didymos, a denser, mountain-like object, resisted fragmentation.#nasa #dimorphos #didymos #dart_mission #european_space_agency
European Space Agency's Jupiter Icy Moons Explorer (Juice) Captures Images of Interstellar Comet 3I/ATLAS The European Space Agency's Jupiter Icy Moons Explorer (Juice) recently captured new images of the interstellar comet 3I/ATLAS, which made a brief appearance in our solar system in late 2025. These images, transmitted from the spacecraft’s distant vantage point, provide a rare glimpse into the comet’s fleeting journey through our cosmic neighborhood. The comet, first detected in July 2025 as the third known object originating outside our solar system, has become a subject of intense scientific interest due to its unusual origin and trajectory. NASA officials and scientists have consistently emphasized that 3I/ATLAS is not extraterrestrial in nature but rather a naturally occurring celestial body that formed elsewhere in the galaxy. However, its unique path and composition have sparked fascination among astronomers. The comet’s brief visit to our solar system has allowed researchers to study planetary material that formed under different stellar conditions, offering insights into the diversity of objects in the universe. The Juice orbiter, en route to Jupiter, observed 3I/ATLAS between November 2 and November 25, 2025, during a period when the comet was in a highly active state. This activity followed its closest approach to the sun on October 30, 2025, which likely triggered the release of gas and dust. Due to the spacecraft’s position on the opposite side of the sun from Earth, scientists did not receive the data until February 2026. The first images released by the European Space Agency in late February showed the comet spewing gas and dust from a distance of 41 million miles, with a bright coma and a long tail visible.#nasa #3i_atlas #european_space_agency #jupiter_icy_moons_explorer #jet_propulsion_laboratory
European Space Agency Captures Detailed Image of Interstellar Comet 3I/ATLAS The European Space Agency has released a new image of the interstellar comet 3I/ATLAS, captured by its Juice spacecraft as it traveled toward Jupiter. The image shows the comet near the Sun, where it was ejecting dust and gas, revealing a bright halo of gas surrounding its nucleus, known as the coma. A long tail is also visible, along with jets, streams, and filaments emanating from the comet. The image was taken by the Juice spacecraft’s science camera, JANUS, on November 6, 2025, seven days after the comet passed its closest point to the Sun. At the time, Juice was approximately 66 million kilometers away from the comet. This marks the second image of 3I/ATLAS captured by Juice, following a previous one taken with its Navigation Camera in November 2025. The new image, however, allows scientists to study the comet’s structure in greater detail. 3I/ATLAS, discovered on July 1, 2025, is one of only three interstellar comets ever identified. It is believed to be the oldest comet ever found, potentially older than the Sun itself. Formed in another part of the galaxy, it is passing through the Solar System as part of its journey. Scientists suggest it may originate from a region beyond our Solar System, making it a rare object for study. Juice’s mission to Jupiter includes investigating the icy moons of the gas giant, which are thought to harbor subsurface oceans and could be potential habitats for life. The spacecraft used five science instruments—JANUS, MAJIS, SWI, PEP, and UVS—to analyze 3I/ATLAS during November 2025. These tools collected data on the comet’s composition, behavior, and interactions with solar radiation.#3i_atlas #european_space_agency #juice_spacecraft #janus_camera #jupiter_mission
