RESEARCH ☄️
Comet 3I/ATLAS, only the third interstellar object ever seen, may be older than the Sun.
An international team measured its carbon and nitrogen isotopes with ESO's Very Large Telescope, revealing a chemistry that points to an ancient, low-metallicity star.

ICYMI The 3I/ATLAS comet might be older than the Sun itself.
Astronomers used our Very Large Telescope to study the composition of 3I/ATLAS, the brightest interstellar object ever spotted ☄️
They found that the comet likely originated in the outskirts of an old star system, indicating that it may be much older than the Sun.
