James Webb Space Telescope takes 1st look at interstellar comet 3I/ATLAS with unexpected results

Description:

The James Webb Space Telescope has observed the interstellar comet 3I/ATLAS for the first time, using its infrared instruments to study the comet’s size, composition, and outgassing. Discovered in July 2025, 3I/ATLAS is the third known interstellar visitor, and JWST detected unusually high levels of carbon dioxide along with water, carbon monoxide, and carbonyl sulfide in its coma. The comet’s composition may reveal the conditions of its formation around another star, possibly near a “carbon dioxide ice line,” and its low water vapor suggests heat struggles to penetrate its icy core, Space.com has reported. At an estimated 7 billion years old, 3I/ATLAS is the oldest comet ever observed, and ongoing JWST observations aim to uncover more about its origin and structure before it exits the solar system. read more: 👍 Like this video to stay updated on James Webb’s groundbreaking study of the interstellar comet 3I/ATLAS. 💬 Comment below—What do you think this discovery tells us about other star systems? 🔗 Share this video to spread the wonder of space exploration. 💰 Support the channel by hitting the YouTube Thanks button, helping us keep delivering exciting astronomy updates. 👉 Don’t forget to subscribe for more coverage of James Webb discoveries and interstellar science.
