New observations with the James Webb Space Telescope reveal the most distant pair of merging black holes ever spotted. The discovery further challenges leading theories of cosmology.

Using the James Webb Space Telescope, scientists have discovered evidence of a carbon-rich atmosphere around the hellish world 55 Cancri e. This marks the best evidence yet of an atmosphere around a rocky exoplanet.

Astronomers using the James Webb Space Telescope have separated the light of a quasar from the light of its surrounding stars, offering unprecedented insight into how the universe's oldest black holes grew.

JWST's surprise discovery of methane emissions and likely aurorae over a distant brown dwarf could indicate this "failed star" is orbited by an active moon.
