Some Facts

As of 2022, the oldest and most distant star that we were able to observe is Earendel. Its light traveled 12.9 gigalight-years to reach us.

With a mass between 50 and 100 solar masses, its lifespan was just a few million years. The star is long gone now and yet, its photons still wander through the cosmos, messengers of the beaming beacon of light it once was.
