NASA Hubble Space Telescope Uncovers One of the Youngest Known Blue Straggler–White Dwarf Systems

Italian astronomers using the Hubble Space Telescope have discovered a white dwarf orbiting a blue straggler star in the globular cluster 47 Tucanae, located 15,300 light-years away. The rare system, among the youngest detected, sheds light on stellar mass transfer and offers vital clues to the evolution of binary stars in dense clusters.
