Amateur footage has captured China's Tiangong space station as it crossed the Moon's face near the prominent Tycho Crater. The stunning transit, recorded by a hobbyist astronomer, shows the station as a bright, fast-moving silhouette against the lunar surface.
The video highlights the visual impact of Tiangong, which orbits Earth at roughly 340 to 450 kilometers in altitude. Transits like this require precise timing and alignment, as the station travels at around 7.8 kilometers per second, making its lunar passage a matter of seconds.
The footage was captured and shared by the astrophotographer, whose expertise in tracking low-Earth orbit objects allowed for the successful recording. Such transits are rare because they depend on the exact position of the observer relative to the station's orbital path and the Moon's location in the sky.
Tiangong, China's permanent space station, has been operational since 2022 and typically hosts three astronauts for extended missions. The station is a key part of China's growing space ambitions, alongside lunar exploration programs.
While the video showcases remarkable amateur astronomy, it also underscores the increasing visibility of spacecraft in orbit as low-Earth orbit becomes more crowded. Tiangong's crisp silhouette reflects both the station's size—about 55 tons—and the improving quality of consumer astrophotography gear.
