AI Reveals New Galaxies in James Webb Space Telescope Images
Known as ASTERIS, the AI network removes noise from images to reveal features a full magnitude fainter than before.
Webb Space Telescope Spies Baby Planetary System
Astronomers have found a baby system that’s just beginning to build planets — and it can tell us about how and where planet formation starts.
Cosmic Fog Lifted Earlier Than Expected
New observations show that the universe's first light penetrated the fog of the cosmic dark ages just 330 million years after the Big Bang.
Flame Nebula Images Show Star Formation Turnover for the First Time
For the first time, researchers have identified a turnover in the initial mass function of a star cluster.
Supernovae Shaped the Early Universe, Webb Telescope Finds
Astronomers have discovered one of the earliest supernovae yet and found that exploding stars may have contributed to the enrichment of the young universe.
Mysterious “Little Red Dots” Give Clues to Early Black Holes’ Formation
A new look at small red galaxies known as “little red dots” reveals that they’re surprisingly abundant in the early universe.
The Webb Telescope Reveals a "Featherweight Giant" Planet
When JWST looked at what was supposed to be a hot Jupiter, it found something else instead: a fluffy, shrinking planet that’s more like Neptune.
Webb Telescope Shows Unexpectedly Crowded Asteroid Belt
A new analysis of archival Webb telescope data reveals small asteroids in the main asteroid belt are far more numerous than thought.
New Views of Vega’s Dusty Disk
High-resolution images reveal the debris disk around Lyra’s brightest star to be exceedingly smooth. If any planets lurk therein, they must be small.
Webb Telescope Images Massive Early Galaxies, Still Finding More Than Expected
Webb Telescope data are still turning up more massive galaxies in the early universe than astronomers expect.
Trio of Early Galaxies Test Our Ideas of Cosmic Evolution
Some galaxies hailing from the infant universe may already hold vast populations of old stars.
Webb Telescope Unveils 19 Galaxies in a New Light
A James Webb Space Telescope survey known as PHANGS has revealed exquisite, just-published details in 19 nearby galaxies.
The Milky Way Might Have Started Out Shaped Like a Pickle
Faraway dwarf galaxies in the universe's distant past — which will become modern Milky Ways — have an unexpectedly stretched-out appearance.
The Webb Telescope's Grand Tour of the Solar System
The James Webb Space Telescope has revealed galaxies in the early universe, hidden star formation, and sniffed the atmospheres of exoplanets. But it's also exploring closer to home, imaging each of the giant planets in detail. The telescope can see aspects of the planets' compositions in ways that passing satellites…
Webb, Hubble Telescopes Team Up to Create "Most Colorful View of the Universe"

Images capture the birth of stars and planets in multiple results from space- and ground-based telescopes.
Another Early-Universe Mystery: JWST Spies Dust at Cosmic Dawn
Dust is usually the product of generations of star formation. So what is all this dust doing in the early universe, just a few hundred million years after the Big Bang?
James Webb Space Telescope Uncovers Hundreds of Galaxies in Early Universe
In the JWST version of the Hubble Deep Field, astronomers are discovering what galactic life was like in the earliest years of the universe.
Red Galaxies at Night, Astronomers' Delight: A Look at the “Hubble-Dark” Universe
JWST images of early galaxies have turned up a population of flat, red disks that may have been entirely missed by previous surveys.
