3I/ATLAS mystery deepens: Discovered on July 1 last year, study suggest the cosmic visitor may be older than the Sun, Earth or any other object in our solar system

An Oxford PhD student, Matthew Hopkins, analyzed 3I/ATLAS, an interstellar object possibly older than our Sun. This visitor, the third confirmed, may originate from a star system formed around 7 billion years ago, originating from the galaxy's thick disc. Its chemical composition offers a unique glimpse into the early universe, providing valuable data for scientists studying cosmic history.
