SETI’s 3I/ATLAS Search Found No Signs of Technology

3I/ATLAS is the third interstellar object observed in the Solar System.
Researchers scanned it for over seven hours from 1 to 9 GHz.
The team reported no signals that warranted additional follow-up.

Subaru Telescope Data Suggests 3I/ATLAS Has a More Complex Interior Than Earlier Readings Indicated

Subaru observed 3I/ATLAS after perihelion and analyzed light from its coma.
The team found a lower carbon-dioxide-to-water ratio than earlier space-based observations suggested.
Researchers say the result points to evolving coma chemistry and offers clues about the object’s interior structure.

JWST Data Suggest Interstellar Comet 3I/ATLAS Is Rich in Methane Ice

3I/ATLAS became the third known interstellar object detected in the Solar System on July 1, 2025.
A new JWST-based analysis says the comet is rich in methane ice.
Its composition could reveal how small bodies form in other planetary systems.

JUICE spots interstellar comet 3I/ATLAS ejecting water at extreme rates

ESA's JUICE spacecraft observed interstellar comet 3I/ATLAS ejecting about two tons of water per second.
The object is only the third known interstellar visitor detected passing through the solar system.
Its activity could help scientists study material linked to planet formation around another star.

NASA Releases Full Interstellar Comet 3I/ATLAS Dataset for Science

NASA has released the full observational dataset for interstellar comet 3I/ATLAS as it exits the solar system permanently
Interstellar comets are material from other planetary systems, the only way to study extrasolar chemistry in situ
The dataset includes spectroscopic, photometric, and imaging data gathered from multiple observatories during the comet's transit
Open access allows the global research community to analyze the data and make discoveries beyond those of the original observing teams

Third Interstellar Comet 3I/ATLAS Marks New Era of Detection

Three interstellar objects detected since 2017 after millennia of none, due to better telescopes
Vera Rubin Observatory could detect dozens of interstellar visitors during its decade of operations
Each visitor carries unique chemical data about the planetary system that ejected it

A white, glowing egg-shaped object lies in the centre of the black-and-white image, on a dark, starry background. Glowing streaks spread upwards from the object. In the top left, a yellow arrow marked ‘Sun’ points straight down, and a blue arrow marked ‘Velocity’ points towards the 7 o’clock direction. In the bottom left, an inset shows the same object on a lighter grey starry background, filled with ragged-edged, concentric egg shapes gradiented black-to-white

JUICE Spacecraft Captures First Image of Interstellar Comet 3I/ATLAS

Third interstellar object ever detected, imaged by ESA's JUICE spacecraft
Shows glowing coma and sweeping tail confirming cometary nature
May help trace the comet's origin to a specific star system
