The SETI Institute has published a report on the interstellar object 3I/ATLAS, confirming that no technosignatures were detected. While the object was determined to be a comet, the study established new protocols for future interstellar object monitoring.
Why it matters
This research contributes to the scientific search for extraterrestrial intelligence and improves methods for analyzing objects entering our solar system.
On July 1st, 2025 , the Asteroid Terrestrial-impact Last Alert System (ATLAS) station announced the detection of another interstellar object (ISO) passing through our Solar System. Following on the heels of 1I/'Oumuamua in 2017 and 2I/Borisov in 2019, 3I/ATLAS became the third ISO to be witnessed by astronomers in the space of eight years. Like 2I/Borisov, this latest visitor began venting gas and dust as soon as it began approaching the Sun, indicating that it was clearly a comet.
