JWST Captures Formation of Earliest Known Galaxies

New observations reveal galaxies forming 400-600 million years after the Big Bang, surrounded by dense gas.

Astronomers used JWST to observe galaxies from 13.3 to 13.4 billion years ago.
These galaxies are enveloped in hydrogen and helium gas, crucial for star formation.
The findings mark the first direct images of galaxy formation during the Cosmic Dawn.
Researchers aim to build larger statistical samples to understand these early galaxies better.
The study provides insights into the Era of Reionization, when the universe became transparent.
