Unlike massive stars, red dwarfs burn hydrogen so slowly that their lifespans can exceed the current age of the universe, sometimes reaching trillions of years.
Studying red dwarfs offers insight into the long-term evolution of galaxies.
It also highlights that most stars in the universe will outlive us by orders of magnitude.
Some red dwarfs born today could still be shining when the universe is trillions of years old.
