The Latest Breaking News from James Webb

The James Webb Space Telescope has confirmed 20-year-old Hubble observations that could finally explain how ancient stars can host massive planets.

Galaxies in the early universe tend to be clumpy, but the new JWST discovery of a "grand design" spiral galaxy just 1.5 billion years after the Big Bang has scientists stumped.

The James Webb Space Telescope has captured an image of a baby, Milky Way-like galaxy that formed more than 13 billion years ago. This "Firefly Sparkle" galaxy could reveal how our own galaxy evolved.

A new theory explains how dozens of mysterious planet pairs discovered by the James Webb Space Telescope, dubbed "JuMBOs," may have formed.

A dense cluster of bright stars, each with six large and two small diffraction spikes, due to the telescope’s optics.

A new JWST study has revealed the true origins of a luminous quasar that has been duplicated six times as its light "zig-zags" through space-time via a phenomenon first predicted by Albert Einstein. The unusual light show could help tackle one of cosmology's biggest problems, experts claim.

The nearby bright star Vega is surrounded by a surprisingly smooth, 100 billion-mile-wide disk of cosmic dust, confirming that it is not surrounded by any exoplanets, JWST images reveal. And scientists cannot explain its lack of alien worlds.

Astrophysicist Ethan Siegel explained why government investments have made great scientific discoveries possible

The light from the most distant galaxy in the known universe suggests that there's something off about our current cosmological models, a new James Webb Space Telescope study finds. The explanations remain elusive.

The James Webb Space Telescope revealed that the hot Jupiter exoplanet HD 189733 b, located just 64 light-years from Earth, has an atmosphere full of hydrogen sulfide, meaning it likely smells of rotten eggs.
