China has become the first nation to capture and publicly release detailed close-up images of the interstellar object 3I/Atlas, overtaking NASA and other space agencies. The images mark a significant scientific achievement, showing the object’s comet-like characteristics.
The Tianwen-1 Mars orbiter, launched by the China National Space Agency (CNSA), captured the images from roughly 30 million kilometres away on October 3. Notably, the orbiter’s camera system was originally designed for mapping Mars, not for tracking faint interstellar bodies.
3I/Atlas is the third confirmed interstellar object ever detected, following 1I/‘Oumuamua and 2I/Borisov. Its observation provides rare data for scientists studying materials from beyond the solar system.
According to the CNSA, the images reveal "distinctive features of a comet," showing a luminous nucleus surrounded by a diffuse halo of dust and gas.
Officials from the Chinese space agency emphasized that capturing these images was extremely demanding because 3I/Atlas was estimated to be between 10,000 and 100,000 times dimmer than any Martian surface area previously mapped by Tianwen-1. Despite this, the mission’s optics and precise navigation enabled the successful capture.
While NASA has also tracked the object, China’s team was the first to produce and share a comprehensive visual record, underlining the growing sophistication of the nation’s space program.
Author’s summary: China’s Tianwen-1 probe became the first to photograph and release high-resolution images of the interstellar body 3I/Atlas, highlighting its comet-like form and advancing deep-space exploration.
