Interstellar comet 3I/ATLAS's tail is still growing, new image shows
A staggering modern picture of interstellar comet 3I/ATLAS (C/2025 N1 Chart book) uncovers the enormous visitor’s particle tail has developed significantly longer and more organized — a sign of powers movement as it proceeds its travel through the inward sun based system.
The picture, captured by the Virtual Telescope Venture at 11:31 p.m. EDT on Nov. 10 (0431 GMT on Nov. 11), is composed of 18 partitioned 120-second exposures, remotely taken by mechanical telescopes found in Manciano, Italy. In spite of the comet being fair 14 degrees over the eastern skyline and a shinning 61% moon sparkling approximately 70 degrees absent, a strongly characterized, glowing particle tail is seen.
“Exploiting the abnormal great climate of this season, we imaged the interstellar comet 3I/ATLAS (C/2025 N1 Map book) once more, recording a much more created particle tail,” Gianluca Masi, Virtual Telescope Extend author and cosmologist, said in a post sharing the modern picture. “Looking at the picture, we see how the particle tail of 3I/ATLAS is clearly appearing way better and way better.” An particle tail shapes when the sun’s bright radiation strips electrons from gas atoms discharged by the comet, turning them into charged particles. These particles are at that point cleared absent by the sun powered wind — a steady stream of charged particles streaming outward from the sun — making a long, regularly somewhat blue tail that continuously focuses specifically absent from the sun in any case of the comet’s heading of travel. This tail varies from the clean tail, which tends to show up yellowish-white and bends delicately along the comet’s orbital path.
In the modern picture, the comet’s shinning center is encompassed by a compact coma and a strongly characterized particle tail extending generally 0.7 degrees over the sky. A black out anti-tail — a highlight caused by the observer’s point of view as tidy trails along the comet’s circle — can too be seen expanding in the inverse heading. The picture appears a clear increment in movement compared to prior perceptions, recommending that 3I/ATLAS is venting gas and tidy more enthusiastically as it responds to sun based heating.3I/ATLAS is as it were the third affirmed interstellar protest ever identified, taking after 1I/’Oumuamua in 2017 and 2I/Borisov in 2019. Not at all like its forerunners, this guest from another star framework is shinning sufficient to be considered in detail by ground-based telescopes, advertising cosmologists a uncommon opportunity to watch how an interstellar comet carries on beneath the impact of our sun.
The developing length and brightness of the tail recommend expanding sublimation of unstable materials — likely counting carbon dioxide and clean — that are at that point cleared into space by the sun oriented wind. Early information recommend that 3I/ATLAS may contain a tall division of carbon dioxide ice, advertising potential clues to the conditions in the removed planetary framework where it shaped, as well as important knowledge on how comets advance past our sun oriented neighborhood.
The Virtual Telescope Extend will proceed to screen 3I/ATLAS as it voyages through the inward sun based framework. You can check out past pictures of the comet taken since it was to begin with identified in July of this year.
