In a fresh twist, comet 3I/ATLAS, which is believed to be a comet from outside the solar system, is likely changing color and may be turning bright green as it nears the halfway point on its journey through the solar system. If this surprising transformation turned out to be true, it would possibly be because of the comet's increasing proximity to the sun, Science.com reported, citing experts.
The latest observation about the comet 3I/ATLAS visitor surfaced from new photos of the interstellar visitor, which were taken on September 7, 2025 during the "blood moon" total lunar eclipse by astrophotographers Michael Jäger and Gerald Rhemann, according to media reports.
The new shots of the comet were snapped in the dark skies over Namibia. These images were taken when the full moon passed through the darkest part of Earth's shadow, meaning that the skies were darker than normal for that time of month.
What did new images reveal about the 3I/ATLAS
The fresh set of images of the comet revealed that its increasing proximity to the sun has caused it to "turn green" as new rarer chemicals are expelled from its core, according to Spaceweather.com.

It is however too soon to comment with certainty with a handful of images as no other photographers or observatories have so far witnessed this change. The new observations claimed that the object's coma has now transitioned from giving off red light to green.
What did Harvard astronomer Avi Loeb say about the comet's color change
Harvard astronomer and noted alien hunter Avi Loeb highlighted in his recent blog post on the findings, this could be due to a "steep rise in the production of cyanide," according to media reports.
According to ATLAS telescope team’s data, the object's "anomalous evolution" is shifting from "scattering of sunlight by dust lifted from a reddened surface to the production of small, optically bright icy grains, which changed the opacity of the plume of materials shed off by 3I/ATLAS," Loeb explained, according to Futurism. It was the ATLAS telescope team which first spotted the object and after which the space rock is named.
The object, known as Comet 3I/Atlas, was discovered on July 1, 2025 by the Asteroid Terrestrial-Impact Last Alert System (ATLAS) survey telescope in Río Hurtado, Chile. It is only the third known interstellar object to pass through our solar system.
