🏜️ Xinjiang: Science Across the Dryland | EP2 Desert management is about more than stopping the sand. Deserts may look static, but they are constantly changing. To manage them, we need to understand how they evolve and how wind, water, soil and vegetation interact. From water-saving afforestation to sand control and salt-tolerant plants, we are exploring ways to combine sand control, salinity management and ecological development. 🎬 Watch EP2 and discover how science is helping us understand Xinjiang's changing deserts. #ThirdXinjiangScientificExpedition #Drylands #Ecology #Deserts

Could a real-life "Three-Body Problem" exist? 🌌 In The Three-Body Problem, three stars create a fascinating cosmic puzzle. In real life, we've found a rare triple-star system containing a pulsar, a white dwarf and a Sun-like star. How did these three stars end up in a rare triple system? 🎬 Watch the video to follow their journey through stellar evolution. #ThreeBodyProblem #Astronomy #Pulsar #StellarEvolution #SpaceScience #SciFi

🌌 We've identified the first known pulsar triple system still evolving! Chinese and European teams independently confirmed the system. By combining publicly available data from multiple space missions, we precisely determined its orbital parameters and the masses of all three members. The system contains: 🔭 Pulsar PSR J0435+3233 — ~1.16 or 1.34 solar masses, from two solutions within the same model ⚪ White dwarf — ~0.3 solar masses ⭐ Sun-like star The Sun-like star orbits the inner binary (8-days period) every 73.5 years on an eccentric orbit.

🔭 10 Years of FAST: Keeping Our Eyes on the Universe Ten years ago, on September 25, 2016, FAST was completed in Guizhou, China. Since then, the world's largest single-dish radio telescope has been listening to the Universe, helping scientists explore pulsars, galaxies, interstellar matter and more. 🌌 Ten years on, the journey of discovery continues. Happy 10th anniversary, FAST! 🎉 #FAST #RadioTelescope #RadioAstronomy #Astronomy #Space #Universe

🌕✨ On September 25, FAST celebrates the 10th anniversary of its completion — and this year, the milestone falls on the Mid-Autumn Festival, when families and friends gather to celebrate under the full Moon. For the past decade, FAST has been listening to faint signals from deep space and helping scientists uncover new stories about the universe. FAST is open to scientists worldwide, and we can’t wait to see what the next decade will bring. 🔭🌌 Happy 10th anniversary since FAST’s completion, and Happy Mid-Autumn Festival! 🌕 #FAST #RadioTelescope #Astronomy #MidAutumnFestival #HappyAnniversary

🌕 One Moon, Many Stories: Celebrating Mid-Autumn Festival at Science Island We invited international researchers and students at Science Island to celebrate the Mid-Autumn Festival with us.

Different cultures, shared stories, and one Moon brought us all together to celebrate. 🌕🏮 #MoonStories #CulturalExchange #ScienceIsland #CelebratingTogether

🌌 We've traced the journey of high-energy cosmic particles across 42 light-years. Using joint observations from the Einstein Probe (EP) and the Large High Altitude Air Shower Observatory (LHAASO), we’ve discovered an extraordinarily long X-ray tail near a pulsar about 4,600 light-years from Earth. Stretching about 42 light-years, the tail aligns with ultrahigh-energy gamma-ray emission detected by LHAASO, providing new evidence that high-energy particles can travel through interstellar space along a preferred direction.

🌌 We've discovered the lowest-mass double neutron star system known to date! Using FAST, we identified PSR J1856-0039, with a total mass of just 2.488 Suns and an orbital period of 2.36 hours. The system offers a rare test of general relativity, showing effects including gravitational redshift, time dilation and orbital decay caused by gravitational-wave emission. The pair is expected to merge in ~82 million years. 🔭✨ #CAS #FAST #NeutronStars #Astronomy #GeneralRelativity #GravitationalWaves

⚡ This isn't CGI. We actually triggered lightning — on purpose! A rocket trails a thin metal wire into the sky, triggering an imminent natural lightning strike a fraction of a second early and guiding it to a designated location — like a thin thread pulling lightning down from the clouds. Why do this? Natural lightning is unpredictable and fleeting. Artificial triggering allows scientists to observe lightning up close, develop detection technologies and test lightning protection. 🎬 Hit play and watch us bring lightning down from the sky! #CAS #IAP #AtmosphericScience #LightningResearch #Thunderstorm

🔭 What if AI could help run a telescope? The StarWhisper Telescope, developed by the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC), was featured among the "Selected AI Agents 2025 in Physics, Astronomy, Chemistry and Materials Science" in Stanford HAI's AI Index Report 2026. We're exploring how AI agents can go beyond data analysis to help plan and execute astronomical observations, while a digital simulation environment allows us to test observation strategies and optimize telescope operations—without using valuable observing time. 🤖🌌 #CAS #StarWhisperTelescope #AIForAstronomy #Astronomy #AIAgents #SpaceScience

✨ We've uncovered a 100-million-year-old "firefly" revealing the early evolution of insect communication. 🐞 Preserved in Burmese amber, the newly discovered firefly-like beetle Icaroramusretains unusual antennae and light-producing organs. Its antennae may have helped detect chemical signals and find mates. Its light-producing organs may have served defense functions, while possibly representing an early step toward light-based communication. This tiny insect shows that ancient firefly relatives had already evolved complex sensory systems over 100 million years ago.

🌌 We've observed how matter travels through the cosmic web. Using SDSS data, we found that satellite galaxy motions are linked to cosmic filaments, providing observational evidence for a two-stage process: 1/ Matter first flows into filaments. 2/ It then travels along them toward galaxy groups and clusters. Cosmic "highways" leave "tire tracks" in galaxy motions. ✨ Read more: english.cas.cn/newsroom/rese… #CosmicWeb #Astronomy #Galaxies #SpaceScience #Universe #Cosmology #GalaxyEvolution

🔬We've made the most precise measurement yet of the Λ hyperon's electric dipole moment (EDM), improving precision by about 1,000× over the 1981 result. 🌀The Λ hyperon is a short-lived subatomic particle containing a strange quark. Its EDM describes a tiny imbalance in how positive and negative charge is distributed. ⚛️Using quantum entanglement between Λ and anti-Λ hyperons, we found no significant EDM signal—but demonstrated a new way to study fleeting particles and probe new physics.

🌌 The universe's star factory is slowing down—but it's not running out of fuel. We analyzed 2.5 million galaxies with data from FAST & DESI and discovered that fewer stars are forming not because galaxies lack neutral hydrogen, but because they are becoming less efficient at turning this gas into star-forming molecular hydrogen. ✨ A new clue to why galaxies fade over cosmic time.

🌌 We've identified the most powerful cosmic particle accelerator ever found. Using LHAASO, we confirmed Cygnus X-3 as the first variable PeV gamma-ray source, accelerating particles to at least 30 PeV.

🎉 A 50-year mystery in particle physics, solved! Using the Beijing Electron Positron Collider, we and our collaborators have identified that X(2370) is a glueball‑dominated state—a unique form of matter whose main component originates from gluons, the carriers of the strong force.

HIAF's first physics result during commissioning: the observation of hafnium-153, an extremely rare nuclide. Using storage-ring-based isochronous mass spectrometry—a high-precision technique for "weighing" atomic nuclei traveling at high speed—we identified 10 hafnium-153 ions, a remarkable achievement given how rare this nuclide is. The observation expands the known chart of nuclides and provides valuable data for testing models of nuclear structure. More importantly, it demonstrates HIAF's capability to explore previously unknown atomic nuclei.
