As 3I/ATLAS Makes A Close Approach To Jupiter, Astronomers Find It May Be Far More Ancient Than We Thought

The team attempted to pin down the visitor's origins, finding it is "unlike any Solar System body" and came from a different part of our galaxy altogether.

Isotopic Evidence For A Cold And Distant Origin Of The Interstellar Object 3I/ATLAS - Astrobiology

Interstellar objects provide the only directly observable samples of icy planetesimals formed around other stars, and can therefore provide insight into the diversity of physical and chemical conditions occurring during exoplanet formation. Here we report isotopic measurements of the interstellar comet 3I/ATLAS, which reveal an elemental composition unlike any Solar System body. The water in […] The post Isotopic Evidence For A Cold And Distant …
