James Webb Space Telescope Observes Distant Jellyfish Galaxy
On February 18, 2026, astronomers using the James Webb Space Telescope identified a jellyfish galaxy named COSMOS2020-635829. This galaxy is located approximately 8.5 billion light-years away in the COSMOS field. It is undergoing gas stripping as it moves through a dense cluster environment, a process that offers new insights into early galaxy evolution. The discovery highlights the dynamic interactions affecting galaxies in the early universe.
The research involved astronomers including Dr. Ian Roberts from the University of Waterloo. Observations related to this discovery also have connections to Takanezawa, Japan. The findings were published on the same day, emphasizing the significance of this distant galaxy in understanding cosmic history.
