If 3I/ATLAS isnt an alien probe, its discovery may be even more important. Scientists detected no radio signals from the interstellar comet despite an extensive search for technosignatures. Instead, the James Webb Space Telescope found unusually high methane and carbon dioxide levels. Those findings suggest 3I/ATLAS formed in a vastly different star system. More than a space mystery, this methane-rich interstellar object acts as a cosmic time capsule, carrying rare clues about planetary formation, comet chemistry, and the hidden diversity of worlds beyond our Solar System.

The view coming back from NASA’s James Webb Space Telescope has a way of turning familiar categories of comet science slightly awkward. 3I/ATLAS, an interstellar object only…

NASA spacecraft observed the celestial iceball as it swung past Mars last October, venturing within 19 million miles

The SETI Institute said Wednesday that extensive radio scans by its telescope in Northern California found no signs of otherworldly technology from our solar system’s latest…

There were no ‘technosignatures’ from comet 3I/ATLAS, the third known object from a faraway star.

Even though astronomers didn’t detect alien tech signals from a rare interstellar visitor, the results are worthwhile, they say

Das SETI-Institut hat auf einem breiten Bereich von Frequenzen bei 3I/ATLAS nach Spuren außerirdischer Technik gesucht. Das Ergebnis habe man erwartet.

"The results from 3I/ATLAS show how realistic it is to detect a signal with the technology we have today."

Scientists at the SETI Institute searched for technological signals from 3I/ATLAS, the third interstellar object observed in our Solar System. Using the Allen Telescope Array…

3I/ATLAS is the third known interstellar object – leading to suggestions that it could be an alien spacecraft

After comet 3I/ATLAS reached perihelion, JWST took another look and detected methane on an interstellar object for the first time.
