Astronomers analyzing archival images from JWST have discovered an unexpectedly vast population of the smallest asteroids ever seen in the asteroid belt between Mars and Jupiter.

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

The James Webb Space Telescope has spotted five galaxy candidates dating to just 200 million years after the Big Bang, making them the earliest ever detected. And there could be many more.

This week, the James Webb Space Telescope zooms in on the iconic Sombrero Galaxy, revealing the first-ever mid-infrared observations of the hat-shaped wonder.

The James Webb Space Telescope and the Hubble Space Telescope recently released a chilling view of two spiral galaxies, IC 2163 and NGC 2207, merging into one.

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.

From nebulas and black holes to baby star nurseries and ancient collisions, the universe has never looked more beautiful thanks to NASA's $10 billion-telescope.

The James Webb Space Telescope has discovered lonely quasars in the early universe, with "empty larders" that defy theories surrounding their growth to monster sizes.

Some of the earliest galaxies found with JWST are also the brightest. That's a problem for our ideas about the universe.

Using the James Webb Space Telescope, astronomers have discovered carbon dioxide and hydrogen peroxide at the surface of Pluto's largest moon, Charon, potentially shedding light on its origins.
