Leaked 3I/ATLAS Footage From Russia and China Reveals What NASA Tried to Erase From History!

On July 1, 2025, the Atlas Telescope Network in Chile, part of the Survey Telescope Network Asteroid Terrestrial Impact Last Alert System, detected an object designated Three-ey Atlas. Soon after, astronomers confirmed that it was an interstellar comet, only the third known to pass through our Solar System, following ‘Oumuamua and 2I/Borisov.

Interstellar objects are bodies whose orbits are not bound to the Sun, with orbital eccentricities greater than one. This means they pass through the Solar System only once and then leave, instead of orbiting repeatedly like planets or typical comets. Their speed and trajectory indicate an origin outside our Solar System.

Astronomers devoted many hours to observing Three-ey Atlas, measuring its brightness, tracking its coma—the cloud of gas and dust surrounding the comet’s nucleus—and capturing its spectrum. The object was moving extremely fast, with an estimated heliocentric speed of approximately 209,000 km/h. However, during a critical 36-hour window in late September, several major Western observatories were simultaneously offline. Hubble was undergoing gyroscope calibration, the James Webb Space Telescope (JWST) shifted mission priorities, the Very Large Telescope (VLT) in Chile performed mirror maintenance, and both Gemini North and Gemini South were paused.

Individually, each of these events was routine, but together they created a gap in Western optical and infrared coverage. During this period, Three-ey Atlas moved into a part of the sky close to the Sun’s glare, making timely observations crucial to track its activity. For comets, activity includes outgassing and dust emission, which usually peak as they approach the Sun. Missing data during this time meant losing vital information about the timing and intensity of these peaks.

Meanwhile, several observatories in China, including high-altitude stations in Tibet, Ching Hai, and Yunnan, remained fully operational. Their schedules and daylight-night cycles did not overlap with Western maintenance periods. These continuous observations became the only source of data during this blackout, underscoring an important technical reality: global coverage is only as strong as its weakest link. Even with world-class telescopes, simultaneous downtime in one hemisphere can leave fast-moving objects unobserved.

As this observational gap occurred, astronomers focused on measuring the comet’s physical signs: its coma, tail development, and outgassing signature. The coma is the diffuse cloud of gas and dust surrounding a comet’s nucleus when ices sublimate directly from solid to gas under solar heating. The tail is the stream of dust and gas pushed away by solar radiation and the solar wind.

From mid-July onward, multiple instruments began collecting key data. Hubble provided high-resolution imaging, helping constrain the nucleus size, estimated between 300 meters and 5.6 kilometers, depending on the coma’s brightness. JWST and the Spherex mission detected a coma dominated by carbon dioxide, with smaller amounts of water and other volatiles. The CO2 cloud extended hundreds of thousands of kilometers from the nucleus.

This is significant because, in typical Solar System comets, water sublimation dominates near the Sun. The high CO2-to-H2O ratio in Three-ey Atlas suggests a different thermal or compositional history, possibly forming in a colder outer region of its parent star system or having its ices processed before ejection. Continuous monitoring by Chinese observatories recorded the comet’s response to solar radiation—the so-called “echo”—capturing brightness increases, coma expansion, and tail growth.

Measurements of the nucleus’s size were inferred by subtracting dust-scattered light from coma brightness. Comparing Hubble and JWST data with scattering models allowed scientists to estimate dust grain size distributions, crucial for calculating the dust-to-gas mass ratio and understanding the comet’s physical structure and origins. The “echo” is not just a poetic term—it represents how the comet’s molecules and particles responded to the Sun.

During the Western blackout, high-altitude Chinese observatories functioned as continuous “data factories.” Ali Observatory, Ching Hai, and Yunnan transmitted raw files to local high-performance servers before sending them to central archives in Nanjing and Beijing. Thin air and low humidity reduced atmospheric noise, improving optical and near-infrared signal quality. Observations were recorded with 1–2.5 meter mirrors onto CCD or CMOS detectors cooled with liquid nitrogen, calibrated with dark frames, bias frames, and flat fields, and stored in the FITS format.

These observatories captured hundreds of gigabytes of images and spectra during the 36-hour period, providing uninterrupted photometric sequences. When Western systems resumed, these data formed the definitive baseline for the comet’s position and brightness. The gap was caused not by technical failure but by routine scheduling and maintenance cycles across multiple observatories.

Combining data from Western and Chinese telescopes required careful calibration. Photometry was standardized to the AB magnitude system, spectra were wavelength-calibrated, and astrometry was referenced against Gaia DR3, achieving sub-arcsecond precision. This confirmed that Three-ey Atlas remains on a hyperbolic trajectory with an eccentricity of ~1.19, verifying its interstellar origin. Cross-checks by teams in Hong Kong and Taiwan strengthened international confidence in the results.

The story of Three-ey Atlas illustrates that in astronomy, “aperture” represents not just the size of a telescope’s mirror but also access, capability, and opportunity. While most large telescopes are concentrated in the Americas and Europe, smaller, automated telescopes with widespread geographic coverage—like those in China—can rival or surpass the effective cadence of giant instruments for fast-moving or transient objects. Duty cycle, automation, and geographic distribution often outweigh raw mirror size for these purposes.

In short, Three-ey Atlas demonstrates that continuous observation requires both technological capability and global coordination. Distributed networks of smaller telescopes can provide coverage that even the largest observatories cannot achieve when scheduling gaps occur. In astronomy, as in governance, aperture is both power and opportunity.
