Summary
At the Big Bang 13.8 billion years ago, only the light elements hydrogen, helium and a little lithium were initially formed. All the other, heavier elements formed only by nuclear fusion in stars. From the frequencies of various isotopes measured at 3l/Atlas, the researchers were therefore able to determine the age of the comet over nine billion years.
Furthermore, After the asteroid Oumuamua and the comet Borisov, it is only the third interstellar object detected by astronomers while traversing our solar system. Unusual Comet: Visitors to another star are older than our Sun. Discovered a year ago, Comet 3l/Atlas not only comes from another planetary system, but is also at least twice as old as our Sun.
In addition, This showed that 3l/Atlas has different isotope ratios than the comets of our solar system, especially in the elements carbon and nitrogen.
