"Stellar Populations in Metal-Poor Dwarf Galaxy Explored by Astronomers"

Astronomers have used the James Webb Space Telescope to study the stellar populations of the extremely metal-poor blue compact dwarf galaxy I Zwicky 18. Their observations revealed extreme populations of bright, recently formed massive stars, as well as candidate populations of dusty evolved stars and young stellar objects. The study provides important insights into the demographics of younger and older stellar populations in this galaxy, making it an ideal laboratory to study star demographics in an environment similar to that found shortly after the Big Bang.
