A pair of new studies has revealed that the hellish skies of exoplanet WASP-121b contain silicon monoxide gas, which has never been found in any planetary atmosphere to date.

The James Webb Space Telescope has broken its own record once again, spotting the most distant, early galaxy in the known universe. The new contender is MoM-z14, a galaxy visible just 280 million years after the Big Bang.

The discovery of water ice around a distant star is allowing scientists to study how the key ingredient for life is delivered to young planets beyond our solar system.

Scientists looked at Jupiter's massive auroras using the James Webb and Hubble Space Telescopes — and found a mystery they can't fully explain.

Using the James Webb Space Telescope, astronomers have peered into galaxies that existed at cosmic noon to hunt ravenously feeding black holes and bursts of starbirth.

Astronomers have used the James Webb Space Telescope (JWST) to revisit a misunderstood black hole thought to be gulping matter 40 times faster than the theoretical limit. It turns out, dust may have obscured the truth.

The James Webb Space Telescope has pointed its infrared optics at the 'Crystal Ball Nebula' NGC 1514, a planetary nebula studied since the late 1800s.

The James Webb Space Telescope has discovered Zhúlóng, a candidate for the most distant spiral galaxy in the universe. The perplexing Milky Way 'twin' dates to 1 billion years after the Big Bang, and appears too big to explain.

Scientists thought they saw a distant star swallow a planet for the first time ever. But new observations from the James Webb Space Telescope suggest something very different, but equally rare, may have happened instead.
