The Latest Breaking News from James Webb

In today’s newsletter: Astronomers have detected chemical signatures on ​distant exoplanet K2-18 b that could hint at biological activity, though debate remains

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."

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.

It's been a big year for science news.
