Interstellar Comet 3I/ATLAS Displays Bright Green Glow in New Photos

Quick Summary

• Comet 3I/ATLAS, an interstellar object, may be turning radiant green as it approaches the sun, according to astrophotographers Michael Jäger and Gerald Rhemann.
• The comet was first spotted in July, traveling at over 130,000 mph from beyond Jupiter’s orbit and is thought to originate from outside the solar system.
• Currently growing a traditional cometary tail due to its increased proximity to the sun, it is releasing ice, gas, and dust from its core.
• spectroscopic analysis did not detect “dicarbon,” a molecule responsible for similar green hues in other comets. Cyanide has been identified as another potential cause of the coloration.
• More observations are needed to confirm this rare coloration. The comet will temporarily be out of view after passing behind the sun but reappear for closer Earth observation in December.

Indian Opinion Analysis

The potential green transformation of Comet 3I/ATLAS adds scientific intrigue with direct relevance to astronomy’s understanding of interstellar visitors. If confirmed by further observations following its flyby near Mars next month or later during Earth’s observation window in December, this discovery could help refine theories around how ancient interstellar objects interact with solar radiation.

For India-a spacefaring nation investing heavily in planetary exploration through missions like Chandrayaan and Aditya-L1-the study of such phenomena aligns with broad goals aimed at advancing cosmic understanding. Collaboration between global observatories reinforces India’s role within international dialogues centered on space science while increasing opportunities for educational engagement around celestial events like this.
