The James Webb Space Telescope has taken its first look at the near-Earth asteroid 2024 YR4 before a perilous close approach in 2032. The telescope confirmed Earth is safe, but there is a 3.8% chance that our moon may be in trouble.

If such worlds exist, they could be among the most common life-bearing planets in the galaxy.

Scientists studying one of the earliest known galaxies using the James Webb Space Telescope have found that the universe's Era of Reionization may have occurred much earlier than previously thought.

The spectacular image shows a "cosmic tornado" being burped out from a baby star.

Astronomers using the James Webb Space Telescope have discovered an object they've dubbed 'Big Wheel,' a gargantuan galaxy spinning through the early universe and growing larger by the second.

Scientists have made the record-breaking detection of oxygen in an ancient galaxy that existed just 300 million years after the Big Bang. The detection is prompting astronomers to rethink how quickly stars and galaxies formed in the young universe.

Trained on the spectacular Flame Nebula, the Hubble and James Webb Space Telescopes went hunting for the smallest stars in the universe.

The James Webb Space Telescope has spotted a 'rogue' cosmic object barrelling through our galaxy without a star, and covered in clouds of iron and magnesium minerals.

Such a dramatic cut to a flagship space telescope still in its prime will be felt across the mission's entire operations, affecting science.

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.
