James Webb Space Telescope

An artist's concept of a simulated view from the rough, icy surface of the moon Europa with Jupiter looming over the horizon.

Jupiter's Moon Europa May Contain Carbon, a Crucial Ingredient for Life

The James Webb Space Telescope found carbon dioxide on Europa's surface, and astronomers say it likely originated in the moon's vast ocean

The James Webb Space Telescope will help scientists look for signs on life on other planets.

What Would Signal Life on Another Planet?

Astronomers have long debated what kind of chemistry might serve as a bona fide alien biosignature

An artist's rendition of exoplanet K2-18 b and the dwarf star it orbits. New observations from the James Webb Space Telescope support the idea that the world, discovered in 2015, has a hydrogen-rich atmosphere and water ocean.

This Exoplanet May Be a Distant Ocean World, James Webb Telescope Finds

The observatory detected evidence of methane and carbon dioxide—and tentatively observed a molecule that, on Earth, is only made by living things

What Is This 'Cosmic Question Mark' Captured by the James Webb Space Telescope?

Astronomers say the distinct, punctuation-like shape could be a result of galaxies merging

An image of the Ring Nebula captured by the James Webb Space Telescope. The interior of the ring is filled with hot gas and the ring itself is a complex structure made up of thousands of dense clumps of hydrogen gas.

The supernova, known as Cassiopeia A, is located roughly 11,000 light-years from Earth and could offer insights into cosmic dust and star death

A zoomed-in image of Uranus captured by the James Webb Space Telescope. Eleven of the planet's 13 rings are visible, though some are so bright they appear to blend into one ring.
