"Unveiling Cosmic Nurseries and Tombs in Distant Galaxies"

Observations using ALMA have identified the sites of star formation and a possible site of star death in a galaxy located 13.2 billion light-years away. The high-resolution observations of MACS0416_Y1 revealed the intricate relationship between dust and oxygen emissions within the nebulae, suggesting the ionization of surrounding gas by newly formed stars. Additionally, a massive cavity, potentially a superbubble created by successive supernova explosions, was discovered in the dust-dominated regions. These findings provide insights into the birth and death of stars within nebulae and may be further explored with future high-resolution observations using instruments like the James Webb Space Telescope.
