James Webb Space Telescope

Galaxies sported disks and spiral arms as early as 3.7 billion years ago, according to new data from the James Webb Space Telescope.

The James Webb Space Telescope has observed galaxies defying the "cosmic rulebook" in the early universe, to the surprise of astronomers who hope to learn more about the evolution of the universe.

The James Webb Space Telescope has observed a source of carbon, a vital ingredient for life, on Jupiter's icy moon Europa.

Researchers have shown that if the James Webb Space Telescope was pointed at Earth from a distant star, it could detect the signatures of intelligent life in our planet's atmosphere.

NASA's James Webb Space Telescope captured stunning jets blasting out of a protostar, shedding light on the makeup of very young, sun-like stars.

A big telescope on the moon could peer deeper into the universe than the famed James Webb Telescope and perhaps even help find life on exoplanets, scientists say.

Scientists still can't nail down the rate at which our universe is expanding. New JWST observations didn't make things any easier.

The exploded guts of a supergiant star are giving up new secrets in a case of stellar CSI.

A James Webb Space Telescope image of M51 boasts amber hues and reddish streaks, capturing the galaxy's gravitational relationship with a neighboring realm.

The JWST team announced that a mode of one of the observatory's infrared sensors indicated a reduction in the amount of light registered by the instrument.
