Study Reveals Interstellar Comet 3I/ATLAS Could Be The Oldest Object Detected In Solar System
The findings surprised researchers, who used the comet's composition to better understand the environment in which it formed.
-
Scientists May Have Solved the Missing Sulfur Mystery in Star-Forming Clouds
A new simulation suggests sulfur in star-forming clouds may be locked inside icy dust grains through previously overlooked chemical reactions. The findings offer fresh clues to a decades-old cosmic mystery and could improve our understanding of life's essential ingredients in space.

SETI Scientists Searched Interstellar Comet 3I/ATLAS for Alien Signals
SETI researchers used the Allen Telescope Array to scan interstellar comet 3I/ATLAS for artificial radio signals. No techno-signatures were detected, but the observations improved methods for future searches.
-
NASA's James Webb Space Telescope Detects Methane On Interstellar Comet For First Time, Reveals Unusual Chemistry
The observations further confirmed that comet 3I/ATLAS remains unusually rich in carbon dioxide.

European Space Agency's Spacecraft Captures Close-Up Image Of Interstellar Comet Releasing Dust
A recent image shared by the European Space Agency's Jupiter Icy Moons Explorer (Juice) reveals a close-up view of the interstellar comet 3I/ATLAS.
-
NASA Scientists Observe 'Dramatic' Increase In Brightness Of Interstellar Comet 3I/ATLAS
SPHEREx detected a mix of molecules streaming off the comet, including water ice, carbon dioxide, and rocky material.

SPHEREx Captures Dramatic Outburst of Interstellar Comet 3I/ATLAS
NASA’s SPHEREx telescope captured a dramatic outburst from interstellar comet 3I/ATLAS after its close solar flyby in October 2025. Infrared observations in December revealed water vapor, carbon dioxide, methanol, methane, and cyanide erupting from the comet’s nucleus. Scientists say the chemical makeup suggests formation in a relatively warm e...

NASA’s SPHEREx Spots Interstellar Comet Flaring With Gas and Organic Molecules
NASA’s SPHEREx telescope has observed interstellar comet 3I/ATLAS unexpectedly brightening as it leaves the solar system. The comet released water vapour, carbon dioxide, and organic compounds months after its closest solar approach. Scientists say the findings provide a rare chemical snapshot of material formed around another star, helping compa...

NASA’s TESS Captures First Images of Rare Interstellar Comet 3I/ATLAS
NASA’s Transiting Exoplanet Survey Satellite has captured rare images of interstellar comet 3I/ATLAS, only the third such object ever detected. Observations from January 2026 reveal the comet rotates every 15 hours and produces sunlight-driven jets, behaving much like Solar System comets. Scientists say studying 3I/ATLAS may unlock clues about th...
