The Latest Breaking News from James Webb

After 11 years mapping the Milky Way, the European Space Agency's Gaia space telescope has retired. Scientists hailed it as "the discovery machine of the decade."

The James Webb Space Telescope has taken its first look at the near-Earth asteroid 2024 YR4 before a perilous close approach in 2032. The telescope confirmed Earth is safe, but there is a 3.8% chance that our moon may be in trouble.

Scientists studying one of the earliest known galaxies using the James Webb Space Telescope have found that the universe's Era of Reionization may have occurred much earlier than previously thought.

Trained on the spectacular Flame Nebula, the Hubble and James Webb Space Telescopes went hunting for the smallest stars in the universe.

The legendary Hubble Space Telescope has turned its gaze to the Ursa Major-adjacent galaxy UGC 5460, revealing spiral arms, star clusters and a possible supernova "imposter".

In world-first observations, the James Webb Space Telescope is watching two distant alien planets "spilling their guts into space" as they rapidly disintegrate — and scientists are elated at what they've found.

Scientists have traced a repeating fast radio burst (FRB) to the edge of an ancient galaxy where star formation has drastically dropped. Researchers are struggling to explain what caused it.

A space rock dubbed 2024 YR4 has a roughly 2.3% chance of smashing into our planet, NASA scientists announced.

The enormous near-Earth asteroid (887) Alinda has made its closest approach to our planet in decades, and it's about to peak in brightness in a rare once-in-a-decade event. Here's how to watch it live this weekend.

Photos from the James Webb Space Telescope have revealed more than 40 stars within the gravitationally lensed "Dragon Arc" galaxy, 6.5 billion light-years from Earth. It is the largest group of individually imaged stars ever seen at such a distance.

Created by a young star, the bipolar star-forming region Sharpless 2-106 in this Hubble image depicts how intense the star-formation process can get.
