How China's Tianwen-1 Mars Orbiter Imaged Interstellar Object 3I/ATLAS

How China's Tianwen-1 Mars Orbiter Imaged Interstellar Object 3I/ATLAS

China’s Tianwen-1 Mars orbiter has successfully captured images of the interstellar object 3I/ATLAS using its high-resolution camera. CGTN Reporter Wan Hongjia speaks with experts from the Beijing Aerospace Flight Control Center to explain how the observation was carried out, the imaging strategy behind it, and the scientific significance of this achievement.

Discovered on July 1, 2025, by a survey telescope in Chile, 3I/ATLAS is the third known interstellar object to visit the solar system and marks the first interstellar object captured by a Chinese spacecraft.

During the observation, the spacecraft was about 30 million kilometers from 3I/ATLAS, making it one of the closest observations by a probe of this interstellar object.

Scientists believe this object likely formed around ancient stars near the center of the Milky Way, with an estimated age of between 3 and 11 billion years—possibly older than the solar system. This makes 3I/ATLAS a rare sample in studying the composition and evolution of exoplanets, and the early history of stars, holding significant scientific value.

Tianwen-1, China's first Mars mission, carries optical payloads originally designed to image the bright Martian surface. Capturing such a distant and faint object—between 10,000 and 100,000 times dimmer than typical Martian targets—represents the first attempt of its kind for the mission.

China's Tianwen-1 mission, consisting of an orbiter, a lander and a rover, was launched in July 2020. The probe entered Mars' orbit in February 2021 and has been operating stably for roughly four years and eight months.

China was the first country to successfully send an orbiter, lander, and rover to Mars on its first attempt. China is only the second country after the United States to successfully land and operate a spacecraft on Mars.

China's Tianwen-1 Mars Orbiter Captures Images of Interstellar Object 3I/ATLAS

China's Tianwen-1 Mars Orbiter Captures Images of Interstellar Object 3I/ATLAS

The orbiter of China's Mars mission Tianwen-1 has successfully captured images of the interstellar object, called 3I/ATLAS, using its high-resolution camera, according to the China National Space Administration (CNSA).

Discovered on July 1, 2025, by a survey telescope in Chile, 3I/ATLAS is the third known interstellar object to visit the solar system and marks the first interstellar object captured by a Chinese spacecraft.

During the observation, the spacecraft was about 30 million kilometers from 3I/ATLAS, making it one of the closest observations by a probe of this interstellar object.

Scientists believe this object likely formed around ancient stars near the center of the Milky Way, with an estimated age of between 3 and 11 billion years—possibly older than the solar system. This makes 3I/ATLAS a rare sample in studying the composition and evolution of exoplanets, and the early history of stars, holding significant scientific value.

Tianwen-1, China's first Mars mission, carries optical payloads originally designed to image the bright Martian surface. Capturing such a distant and faint object—between 10,000 and 100,000 times dimmer than typical Martian targets—represents the first attempt of its kind for the mission.

"Because 3I/ATLAS follows a hyperbolic orbit, unlike the elliptical orbits of objects around the Sun, it clearly originates from beyond the solar system and will eventually move away from it," said Liu Jianjun, chief designer of the ground application system for China's first Mars exploration mission.

Data received and processed by the ground application system showed clear cometary features in the images. Researchers created an animation from a series of images taken over 30 seconds, demonstrating the object's movement through space. These observations are now being used for further scientific study of 3I/ATLAS.

"From Oct 1 to 4, Tianwen-1 captured images each day and sent the data back to the ground. Using these consecutive images, we were able to create an animation that effectively shows its (3I/ATLAS) flight path," he said.

This successful observation represents an important extended mission for Tianwen-1. The detection of such a faint celestial object serves as a valuable technical test for China's Tianwen-2 mission, which was launched in May—aiming to collect samples from a near-Earth asteroid and explore a main-belt comet, according to the CNSA.

"The successful observation proves the long-term reliability of our orbiter. Tianwen-2 probe will also explore small, faint celestial objects, and we hope to build on this experience to test technology and accumulate expertise for future deep-space missions," Liu added.

The Tianwen-1 team began preparing for the observation in early September. After repeated simulations and feasibility assessments, they determined to use the high-resolution camera on the orbiter and designed optimal imaging strategies, ultimately achieving successful observation.

China's Tianwen-1 mission, consisting of an orbiter, a lander and a rover, was launched in July 2020. The probe entered Mars' orbit in February 2021 and has been operating stably for roughly four years and eight months.

China was the first country to successfully send an orbiter, lander, and rover to Mars on its first attempt. China is only the second country after the United States to successfully land and operate a spacecraft on Mars.

Perspectives on Spiral Galaxies: NGC 4302 (left) & NGC 4298 (right) | STScI

Perspectives on Spiral Galaxies: NGC 4302 (left) & NGC 4298 (right) | STScI

Spiral galaxies are pancake-shaped collections of billions of stars, along with vast clouds of gas and dust. This video illustrates how their observed shapes can differ greatly depending upon the angle at which they are observed. The spiral galaxies NGC 4302 (left) and NGC 4298 (right) are visualized in three dimensions and rotated to showcase how they might look if viewed from other perspectives. Each galaxy could be seen as a roughly circular face-on spiral, as a long, thin, edge-on spiral, or as any of the oblong shapes in between.

The galaxy models are based on observations by the Hubble and Spitzer space telescopes, as well as on the statistical properties of galaxies. Because NGC 4302 is seen nearly edge on, and its structure is not well-defined, its model was based upon observations of the spiral galaxy Messier 51.

NGC 4302 is an edge-on spiral galaxy located about 55 million light-years away in the constellation Coma Berenices. It was discovered by astronomer William Herschel on April 8, 1784 and is a member of the Virgo Cluster.

NGC 4298 is a flocculent spiral galaxy located about 53 million light-years away in the constellation Coma Berenices. The galaxy was discovered by astronomer William Herschel on April 8, 1784 and is a member of the Virgo Cluster.

Comet C/2025 A6 Lemmon & Messier 12 Star Cluster: View from New Mexico, USA

Comet C/2025 A6 Lemmon & Messier 12 Star Cluster: View from New Mexico, USA

Comet Lemmon is brightening and moving into morning northern skies. Besides Comet SWAN25B and Comet ATLAS, Comet C/2025 A6 (Lemmon) is now the third comet currently visible with binoculars and on long camera exposures. Comet Lemmon was discovered early this year and is still headed into the inner Solar System. The comet will round the Sun on November 8, 2025. It passed nearest to the Earth—about half of the Earth-Sun distance—on October 21.

Messier 12 or M12 (also designated NGC 6218) is a globular cluster in the constellation of Ophiuchus. It was discovered by the French astronomer Charles Messier on May 30, 1764, who described it as a "nebula without stars". In dark conditions this cluster can be faintly seen with a pair of binoculars

Distance from Earth: approximately 15,700 light-years

New Mexico is a state in the Southwestern region of the United States. It is one of the Mountain States of the southern Rocky Mountains, sharing the Four Corners region with Utah, Colorado, and Arizona. It also borders the state of Texas to the east and southeast, Oklahoma to the northeast, and shares an international border with the Mexican states of Chihuahua and Sonora to the south.

A Lunar Delight Deep in the Chilean Desert

A Lunar Delight Deep in the Chilean Desert | NOIRLab

A gorgeous gibbous Moon rests above a ridge line near Cerro Pachón, the home of four NOIRLab-operated telescopes including NSF–DOE Vera C. Rubin Observatory, jointly funded by the U.S. National Science Foundation (NSF) and the U.S. Department of Energy Office of Science (DOE/SC); Gemini South, one half of the International Gemini Observatory, supported in part by NSF; and the SOAR Telescope of Cerro Tololo Inter-American Observatory, a Program of NSF NOIRLab.

The particular beauty of the Moon and its features are visible in this delightful image. The dark splotches of ancient, basaltic flats known as maria splatter across our satellite. These features formed when basalt moved from the lunar interior to fill basins on the surface during a time of active volcanism on the Moon. On the left side of the Moon, as seen from this perspective, are the two famous maria: Mare Tranquillitatis (immediately above center left) and Mare Serenitatis (center left). These maria, respectively, were the landing sites for the first and last human visits to the Moon.

On the upper left-hand edge of the Moon, the slopes and edges of the Moon’s other distinct feature, craters, appear starkly against the dark blue sky. One of the most distinct lunar craters, the massive Tycho crater, is in the upper right quadrant of the Moon in this image, flipped almost 180 degrees compared to the view from the northern hemisphere. Craters on the Moon are younger than the maria, and Tycho crater is particularly young, as evident by its sharp appearance.

Expedition 73 flight engineer and Japan Aerospace Exploration Agency (JAXA) astronaut Kimiya Yui: "I took this photo while wondering if everyone in Japan also gazed at the supermoon. Whether you were able to gaze at it or not, please enjoy this video of the moon as seen from space!"

"It feels like a truly miraculous event that the beautiful Earth, with its water and atmosphere, is accompanied by the beautiful moon in addition."

The path the Moon takes as it orbits our planet is not quite a perfect circle. Sometimes the Moon is a little closer to Earth, and appears slightly larger, than average. Sometimes it's a little farther away, and appears slightly smaller.

A “supermoon” occurs when a full Moon coincides with the Moon’s closest approach to Earth in its elliptical orbit, a point known as perigee. During every 27-day orbit around Earth, the Moon reaches both its perigee, about 226,000 miles (363,300 km) from Earth, and its farthest point, or apogee, about 251,000 miles (405,500 km) from Earth.

Haven Demo on Orbit: Extended High-Definition Mission Footage | Vast

Haven Demo on Orbit: Extended High-Definition Mission Footage | Vast

"Haven Demo, our Haven-1 space station technologies test bed is now on orbit and healthy. Watch footage from our onboard cameras . . . [there is] more to come."

With NASA and its international partners set to decommission the International Space Station (ISS) in 2030, the private American space firm, Vast, is racing to launch the first commercial space station that it hopes will ultimately replace the ISS. The company has now completed an important milestone in the production of its first space station.

It launched its pathfinder, Haven Demo, aboard a SpaceX Falcon 9 Bandwagon-4 mission on Sunday, Nov. 2, 2025, from Space Launch Complex 40 (SLC-40) at Cape Canaveral in Florida. Vast is a space station company founded in 2021 by Jed McCaleb. 

The Haven Demo satellite has a mass of 515 kilograms and is expected to last for six months in orbit. With its solar array now deployed, the pathfinder will begin gathering crucial data for Vast's planned orbital station.

Haven Demo will "test radiation tolerant computers, power systems, software, sensors, reaction control systems, propulsion, radios, ground stations, and command and control to inform learnings for Haven-1, the world’s first commercial space station."

"Haven Demo achieved mission success after deploying from SpaceX’s Bandwagon-4 flight on Nov 2, 2025. Following nominal separation and stable sun-pointing, the spacecraft captured 4K video of its solar array deployment and is power-positive."

Vast’s first station, Haven-1, is due to launch no earlier than May 2026, also aboard a Falcon 9.

Haven-1 aims to help Vast beat other contenders for NASA Commercial LEO Destinations Phase 2 (CLD) funding. These companies include Axiom Space (Axiom Station) and Voyager Space/Airbus (Starlab), among others.

“Vast is moving forward at speed, building Haven-1 as the world’s first commercial space station. It is the stepping stone to kick off a larger, more capable multi-module space station and prove our technology, team, and facilities in space with crew,” said CEO Max Haot on X.

Vast’s Haven Demo will test out key capabilities, such as Reaction Control Systems (RCS), power systems, and propulsion, in preparation for Haven-1.

"Now is the time to meet NASA's call to transition its low-Earth orbit presence from the International Space Station (ISS) to a lower-cost commercial option. Vast is preparing to deliver for America and our international partners. We are working on the world's first, most affordable, commercial space station. Haven-1 will be Vast's first step toward a long-term commercial presence in orbit."

"Purpose-built for scientific research, in-space manufacturing, and extended human habitation, Haven-1 will ensure humanity’s continuous presence in space. Backed by a world-class team and built with speed, safety, and efficiency at its core, this marks the next era in human space exploration—not just reaching orbit, but staying there."

Vast Space's Haven-1 aims to be the "world's first commercial space station". "The era of commercial space stations begins with Haven-1, launching next year. Whether you are a sovereign nation, space agency, scientist, company, or private astronaut—the time is now. Join our mission and help pioneer the next giant leap in space exploration."

Flight Through The Orion Nebula in Visible & Infrared Light | STScI

Flight Through The Orion Nebula in Visible & Infrared Light | STScI

This visualization explores the Orion Nebula using both visible and infrared light. The sequence begins with a wide-field view of the sky showing the plane of our Milky Way Galaxy, then zooms down to the scale of the Orion Nebula. The visible light observation (from the Hubble Space Telescope) and the infrared light observation (from the Spitzer Space Telescope) are compared first in two-dimensional images, and then in three-dimensional models.

As the camera flies into the star-forming region, the sequence cross-fades back and forth between the visible and infrared views. The glowing gaseous landscape has been illuminated and carved by the high energy radiation and strong stellar winds from the massive hot stars in the central cluster. The infrared observations generally show cooler temperature gas at a deeper layer of the nebula that extends well beyond the visible image. In addition, the infrared showcases many faint stars that shine primarily at longer wavelengths. The higher resolution visible observations show finer details including the wispy bow shocks and tadpole-shaped proplyds. In this manner, the movie illustrates the contrasting features uncovered by multi-wavelength astronomy.

Interstellar Comet 3I/ATLAS: Galactic Cosmic Ray Effects—New Research Study

Interstellar Comet 3I/ATLAS: Galactic Cosmic Ray Effects—New Research Study

This schematic illustration shows the expected stratigraphy of the irradiated nucleus interstellar comet 3I/ATLAS. Galactic cosmic ray (GCR) irradiation over several circular motions (gyr) alters the outer ∼15–20 m, producing a carbon dioxide CO2-rich crust through CO-to-CO2 conversion, ongoing carbon monoxide CO release from the breakdown of irradiated organics, an organic-rich refractory mantle with a red spectral slope, and compact amorphous ice characterized by low diffusivity and high thermal conductivity. Beneath this layer lies a pristine, unprocessed interior shielded from GCRs, whose composition and structure remain unknown but are expected to differ markedly from the irradiated crust. 

Comet 3I/ATLAS is the third known object from outside our solar system to be discovered passing through our celestial neighborhood. Astronomers have categorized this object as interstellar because of the hyperbolic shape of its orbital path. (It does not follow a closed orbital path about the Sun.) When the orbit of 3I/ATLAS is traced into the past, the comet clearly originates from outside our solar system.

Comet 3I/ATLAS poses no threat to Earth and will remain far away. The closest it approached our planet was about 1.8 astronomical units (about 170 million miles, or 270 million kilometers). 3I/ATLAS and its closest point to the Sun was around Oct. 30, 2025, at a distance of about 1.4 au (130 million miles, or 210 million kilometers) — just inside the orbit of Mars.

The interstellar comet’s size and physical properties are being investigated by astronomers around the world. 3I/ATLAS remained visible to ground-based telescopes through September 2025, after which it will pass too close to the Sun to observe. It will reappear on the other side of the Sun by early December 2025, allowing for renewed observations.

Spectral observations of 3I/ATLAS (C/2025 N1) with NASA's James Webb Space Telescope (JWST) near infrared spectrograph (NIRSpec) and spectro-photometer for the history of the universe, epoch of reionization, and ices explorer (SPHEREx) reveal an extreme carbon dioxide (CO2) enrichment (CO2/H2O = 7.6+-0.3) that is 4.5 sigma above solar system comet trends and among the highest ever recorded. This unprecedented composition, combined with substantial absolute carbon monoxide (CO) levels (CO/H2O = 1.65+-0.09) and red spectral slopes, provides direct evidence for galactic cosmic ray (GCR) processing of the outer layers of the interstellar comet nucleus.

Laboratory experiments demonstrate that GCR irradiation efficiently converts CO to CO2 while synthesizing organic-rich crusts, suggesting that the outer layers of 3I/ATLAS consist of irradiated material with properties consistent with the observed composition of the 3I/ATLAS coma demonstrating observed spectral reddening.

Estimates of the erosion rate of 3I/ATLAS indicate that current outgassing samples the GCR-processed zone only (depth ~15-20 m), never reaching pristine interior material. Outgassing of pristine material after perihelion remains possible, though it is considered unlikely. This represents a paradigm shift: long-residence interstellar objects primarily reveal GCR-processed material rather than pristine material representative of their primordial formation environments.

Follow-up observations of 3I/ATLAS are critical to confirm the above interpretation and to confirm if GCR processing is a "fundamental evolutionary pathway" for interstellar objects.

🚀✨ An Arianespace Ariane 6 rocket lifted off from Europe’s Kourou Spaceport in French Guiana 🌍on Mission VA265, November 4, 2025, at 6:02 p.m. local time, carrying the 🛰 Sentinel-1D Earth observation satellite. Part of the European Union's Copernicus Program, Sentinel-1D will deliver all-weather, Earth day & night radar imagery.

With Ariane 6, Arianespace successfully placed into orbit Sentinel-1D, a Copernicus satellite for the European Commission within the scope of a contract signed with the European Space Agency (ESA).

The Sentinel-1D satellite has an advanced radar instrument to provide all-weather day-and-night imagery of the Earth's surface.

The VA265 mission represents the third commercial flight for Europe's heavy-lift launcher Ariane 6

With this successful launch, Arianespace supports a major environmental mission, while also carrying out its commitment to provide Europe with independent access to space.

With this third commercial flight, Ariane 6, the European heavy-lift launcher operated by Arianespace, successfully placed Sentinel-1D into Sun-synchronous orbit (SSO) at an altitude of 693 km. Spacecraft separation occurred 34 minutes after lift-off.
