#interstellar comet atlas

Astronomers using ESO’s Very Large Telescope (VLT) have measured carbon and nitrogen isotope ratios in 3I/ATLAS, the third known interstellar visitor to sweep through the Solar System.

The interstellar comet 3I/ATLAS carries a chemical fingerprint unlike anything in our Solar System, and it may have formed 10 to 12 billion years ago, before our Sun even existed, according to two papers published in the journal Nature.
