Briefing: DESI maps C-19, an extremely metal-poor Milky Way stellar stream

The C-19 stellar stream, located within the Milky Way's halo, has been the subject of recent observations by an international team of astronomers.

Using the Mayall 4-meter telescope at Kitt Peak National Observatory, the team focused on the stream's composition, which is characterized by extremely low metallicity.

The findings contribute to our understanding of stellar formation and evolution in the early universe, emphasizing the importance of such metal-poor structures in cosmic architecture.
