James Webb Space Telescope

A dazzling new James Webb telescope image of the region near the Milky Way's central black hole reveals thousands of newborn stars among the "most extreme cosmic environment" in the galaxy.

The James Webb and Hubble space telescopes have combined forces to image a cluster of galaxies 4.3 billion light-years away in one of the most colorful pictures of the universe ever taken.

The James Webb Space Telescope has discovered a cosmic 'peanut' and 'fluff ball' that happen to be two of the four oldest galaxies in the known universe.

The James Webb Space Telescope has discovered a massive chain of 20 galaxies in the early universe, raising questions about the formation of the largest structures in the cosmos.

The James Webb Space Telescope has revealed the most detailed image so far of the Crab Nebula, a gorgeous supernova remnant of a star that exploded 1,000 years ago.

A Milky Way doppleganger discovered in the early universe suggests some key physical ingredient is missing from cosmological models.

The universe's early galaxies are way brighter than they should be. The James Webb Space Telescope's discovery of brightly glowing gas around 90% of primordial galaxies may explain why.

The newly identified quasar, observed 13.7 billion light-years away by the James Webb Space Telescope and Chandra X-ray Observatory, could be an example of a heavy black hole "seed" in the early universe.

The hellish super-Earth '55 Cancri e' may be constantly losing and re-growing its atmosphere, a new study of the planet's strange transit signals suggests.

New James Webb Space Telescope observations might be able to explain why clusters of young stars keep turning up near the Milky Way’s central black hole.
