Hubble Space Telescope reveals why some stars refuse to grow old
SMRTR summary
Hubble Space Telescope observations of over 3,000 blue straggler stars across 48 globular clusters have revealed why some ancient stars appear surprisingly young and bright. These "forever young" stars form when binary star pairs in low-density environments slowly exchange material, rejuvenating one star through mass transfer and making it shine hotter and bluer. Dense star clusters disrupt these delicate binary partnerships through gravitational interference, preventing the rejuvenation process and producing fewer blue stragglers.
