The galaxies, each as vast as the Milky Way, are baffling because most scientific models for galaxy evolution suggest processes that would have been slow and inefficient, said Stijn Wuyts, an astronomer from the University of Bath in the United Kingdom.

Check out these 8 images of galaxies, star clusters, supernovas and others captured by NASA James Webb Space Telescope in 2024.

From the mysterious pillars of creation to the mesmerizing images of the deep universe, check out these 7 rare discoveries made by NASA's James Webb Space Telescope.

The James Webb Space Telescope (JWST) is a powerful tool for exploring space, launched in December 2021. It can see faraway objects using infrared light. One important part of the telescope is the Mid-Infrared Instrument (MIRI),

This image by the James Webb Space Telescope showcases a spiral galaxy IC 5332 located 29 million light-years from Earth. The image consists of five galaxies of Stephan’s Quintet which are known as Hickson Compact Group 92 (HCG 92).

If another gravity theory is correct, "then the broader implications are enormous," astrophysicist Stacy McGaugh told Newsweek.

The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming the popular hypothesis that invisible dark matter helped the earliest stars and galaxies clump together.

With highly capable instruments James Webb Space Telescope (JWST) was able to capture the image of a distant galaxy. Arp 107: This image reveals facts about how two galaxies collided hundreds of million years ago and star formation.
