Subaru Telescope Reveals New Data on the Interior Composition of 3I/ATLAS
The Subaru Telescope observed the interstellar comet 3I/ATLAS (C/2025 N1) on January 7, 2026 (UT), after it made its closest approach to the Sun. By observing colors in the coma around the comet, astronomers could estimate the ratio of carbon dioxide to water. This ratio is much lower than that inferred from earlier observations by space telescopes. These findings suggest that the chemistry of the coma is evolving over time and offers clues to t…
A study conducted by the Subaru Telescope revealed new information about the internal composition of comet 3I/ATLAS, the third interstellar object detected in the Solar System. The observations, carried out on January 7, 2026, allowed for a more detailed analysis of the comet's chemistry, especially after its approach to the Sun, which intensified the phenomenon of gas release. Observations of Comet 3I/ATLAS The observations of comet 3I/ATLAS, c…
Subaru Telescope on Maunakea Helps Reveal Changes in Interstellar Comet 3I/ATLAS
Subaru Telescope Public Information and Outreach Subaru Telescope on Maunakea Helps Reveal Changes in Interstellar Comet 3I/ATLAS HILO, Hawaiʻi — Astronomers using the Subaru Telescope on Maunakea have found new clues about the makeup of 3I/ATLAS, a rare interstellar comet that originated outside our Solar System. Their observations suggest that the comet’s chemistry changed as it passed near the Sun, providing new clues to how material in i…
