James Webb Telescope Reveals Insights into Early Galaxies

The James Webb Space Telescope has significantly advanced our understanding of the universe by capturing images of galaxies that mirror the Milky Way. Notably, the galaxy known as 'Firefly Flare' emerged approximately 600 million years post-Big Bang, showcasing ten distinct star clusters.

These findings, led by Lamiya Mowla from Wellesley College, offer valuable insights into the formation and evolution of galaxies, particularly the Milky Way. Additionally, the telescope has uncovered ultra-massive galaxies like Zhúlóng, which displays characteristics of early galaxy formation and challenges previous notions about the timeline of mature galaxies.

Such discoveries underscore the telescope's pivotal role in exploring the cosmos and enhancing our comprehension of stellar development in the early universe.

Astronomers discover an ultra-massive grand-design spiral galaxy

Zhúlóng is an ultra-massive spiral galaxy at redshift ~5.2, serendipitously discovered in the JWST PANORAMIC survey field. It has a classical bulge, large stellar disk with well-defined spiral arms spanning 62,000 light years, and a quiescent-like core with high stellar mass surface densities. Spectral energy distribution analysis points to a quiescent core and star-forming disk, consistent with inside-out galaxy growth and quenching. The star-forming disk has a relatively low star formation r..

James Webb Space Telescope Captures Twin of Milky Way Galaxy

The James Webb Space Telescope has imaged a galaxy called 'Sparkler Galaxy' that closely resembles the Milky Way. This galaxy formed about 600 million years after the Big Bang and contains 10 distinct star clusters. Astronomers say these images provide a unique perspective on the early stages of the Milky Way.
