Astronomers pointed two of the world’s most sensitive radio telescopes at 3I/ATLAS, the third confirmed interstellar object ...

Comet 3I/ATLAS arrived from beyond the Solar System carrying a chemical story unlike anything astronomers had measured before. In the gas around it, they found isotope ratios that do not match the ...

Scientists at the SETI Institute recently searched for technological signals from 3I/ATLAS, the third interstellar object observed in our solar system. Using the Allen Telescope Array (ATA) at the Hat ...

A deep image of interstellar Comet 3I/ATLAS captured by the Gemini Multi-Object Spectrograph (GMOS) on Gemini South at Cerro Pachón in Chile, one half of the International Gemini Observatory and ...

JWST detected rising methane emissions from interstellar comet 3I/ATLAS, exposing ancient interior ice and offering new insights into material that may predate the Solar System.

A comet from another star system does not arrive every year. That is part of what made 3I/ATLAS so compelling when it appeared in July 2025.

The pre-perihelion and post-perihelion observations of the interstellar interloper by Earth-based observatories and ...

Astronomers studying the interstellar comet 3I/ATLAS have found fresh evidence suggesting the object may be more than twice ...

WASHINGTON, June 22 (Reuters) - Scientists studying the comet 3I/ATLAS have determined that this interstellar visitor is remarkably ancient – formed an estimated 10 to 12 billion years ago in a ...

In the latest research, telescope observations of 3I/ATLAS examine its chemical structure and suggest that it took shape in a peripheral region of a relatively calm planetary system ...
