The Webb Telescope Has Captured Its First 'Bulge Fossil Fragment'
The funny-sounding name offers new insights into galaxy formation.
Many of the developments shared by astronomers using the James Webb Space Telescope and similar instruments center on trying to understand the history of the galaxy. The latest update from the Webb telescope researchers confirms the existence of a phenomenon known as "bulge fossil fragments" that can offer new insights on the Milky Way's formation.
The subject of this latest investigation is known as Terzan 5, a region in the center of the galaxy often dubbed "the bulge" that has been challenging for astronomers to study due to the density of stars and presence of dust. Between their observations with the Webb telescope and archival observations taken from the Hubble Space Telescope, the team was able to confirm that Terzan 5 is not a globular star cluster, as it was previously classified. Globular star clusters usually only have one ancient star...
