Astronomers using the James Webb Space Telescope unveiled obscured galaxies in the Spiderweb protocluster, reshaping theories about galaxy formation.
The Spiderweb protocluster shows galaxies in their “teenage” phase, offering insights into how vast cosmic structures assemble over billions of years.
Webb’s infrared capabilities pierced cosmic dust, revealing galaxies previously hidden, enhancing our understanding of the early universe’s structures.
Astronomers discovered more galaxy members in the cluster than anticipated, challenging long-held assumptions about star formation and dust levels.
Findings suggest star formation in these galaxies is fueled by gas accumulation rather than collisions or gravitational mergers as previously thought.
In just 3.5 hours of observing time, Webb revealed significant details about hydrogen gas and galaxy composition within the protocluster.
Astronomers note that as the Spiderweb protocluster grows, the physical traits of its galaxies are transforming, shaping the future of cosmic cities.
Galaxies like the Milky Way in the protocluster were found to be less dust-filled than expected, altering the understanding of their developmental triggers.
Next steps involve spectroscopic observations using Webb to confirm and analyze the newly discovered galaxies, potentially unlocking more cosmic secrets.
