Astronomers using Gaia data have discovered GDR3_526285, an ultra-metal-poor star in the Milky Way's halo with one of the lowest iron abundances ever measured, providing insights into early universe conditions and possibly linked to the Magellanic Clouds.
The James Webb Space Telescope has provided new insights into the Universe's first galaxies, shedding light on the impact of Population III stars and their supernovae. Research suggests that these early stars, through their explosions, injected metals into the surrounding gas, leading to faster formation of subsequent Pop II stars with lower masses. This challenges the notion that the first galaxies were filled with extremely metal-poor stars, providing a clearer understanding of the early Universe.
