Observations of a distant cluster of stars in our galaxy have led to the identification of a new class of objects that serve as galactic building blocks. Researchers utilized the Hubble Space Telescope (HST) and the James Webb Space Telescope (JWST) to examine Terzan 5, which has now been classified as a “bulge fossil fragment” rather than a typical globular cluster.
Observations of a distant cluster of stars in our galaxy have resulted in a new class of objects that turn out to be galactic building blocks. Researchers used Hubble Space Telescope (HST) and the James Webb Space Telescope (JWST) to study the stars that make up Terzan 5, long though to be a globular cluster. What they found puts that cluster into a very rare class of objects called “bulge fossil fragments.”
