How are gas giant exoplanets born? James Webb Space Telescope provides new clues

Relatedly, astronomers may have just pushed the upper size limit of what counts as a planet.

James Webb Space Telescope finds precursors to ‘building blocks of life’ in nearby galaxy

“We found an unexpected chemical complexity, with abundances far higher than predicted by current theoretical models.”

James Webb Space Telescope finds most distant galaxy ever detected: ‘It looks nothing like what we predicted’

“There is a growing chasm between theory and observation related to the early universe, which presents compelling questions to be explored going forward.”

James Webb Space Telescope reveals new origin story for the universe’s 1st supermassive black holes

Recent James Webb Space Telescope data confirms a decade-old theory that the universe’s earliest supermassive black holes formed without stars.

NASA’s James Webb Space Telescope has spotted a young star flinging heat-formed crystals outward on a cosmic conveyor belt, offering a new clue to how comets evolve.

This is the sharpest view ever seen of a black hole’s dusty disk

“Instead of Webb’s 6.5-meter diameter, it’s like we are observing this region with a 13-meter space telescope.”
