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 briefly passing through the solar system, has been watched before, but this time the reading feels less like a routine update and more like a chemical surprise that refuses to sit neatly alongside local comets.

NASA's James Webb Space Telescope has uncovered unusual chemistry in interstellar comet 3I/ATLAS, including the first direct detection of methane on a visitor from another star…

Auf dem Kometen 3I/Atlas wurde Methan nachgewiesen. Es ist der erste Fund von Methan auf einem interstellaren Kometen.

El telescopio espacial James Webb identificó metano, agua y dióxido de carbono en el cometa interestelar 3I/ATLAS. Los datos muestran una composición química poco común frente a…

El observatorio espacial de la NASA localizó el hidrocarburo volátil concentrado cerca del núcleo del cuerpo celeste. El director del Proyecto Galileo sugirió la intervención de…

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

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

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

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…

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