NASA Webb Finds Young Sun-Like Star Forging, Spewing Common Crystals

Astronomers have long sought evidence to explain why comets at the outskirts of our own solar system contain crystalline silicates, since crystals require intense heat to form and these “dirty snowballs” spend most of their time in the ultracold Kuiper Belt and Oort Cloud. Now, looking outside our solar system, NASA’s James Webb Space Telescope […]

Intricacies of Helix Nebula Revealed With NASA’s Webb

NASA’s James Webb Space Telescope has zoomed into the Helix Nebula to give an up-close view of the possible eventual fate of our own Sun and planetary system. In Webb’s high-resolution look, the structure of the gas being shed off by a dying star comes into full focus. The image reveals how stars recycle their […]

NASA’s Webb Delivers Unprecedented Look Into Heart of Circinus Galaxy

The Circinus Galaxy, a galaxy about 13 million light-years away, contains an active supermassive black hole that continues to influence its evolution. The largest source of infrared light from the region closest to the black hole itself was thought to be outflows, or streams of superheated matter that fire outward.  Image: Circinus Galaxy (Hubble and […]

NASA’s Pandora Satellite, CubeSats to Explore Exoplanets, Beyond

A new NASA spacecraft called Pandora is awaiting launch ahead of its journey to study the atmospheres of exoplanets, or worlds beyond our solar system, and their stars. Along for the ride are two shoebox-sized satellites called BlackCAT (Black Hole Coded Aperture Telescope) and SPARCS (Star-Planet Activity Research CubeSat), as NASA innovates with ambitious science […]

Scientists Identify ‘Astronomy’s Platypus’ with NASA’s Webb Telescope

After combing through NASA’s James Webb Space Telescope’s archive of sweeping extragalactic cosmic fields, a small team of astronomers at the University of Missouri says they have identified a sample of galaxies that have a previously unseen combination of features. Principal investigator Haojing Yan compares the discovery to an infamous oddball in another branch of […]

NASA Webb Finds Early-Universe Analog’s Unexpected Talent for Making Dust

Using NASA’s James Webb Space Telescope, astronomers have spotted two rare kinds of dust in the dwarf galaxy Sextans A, one of the most chemically primitive galaxies near the Milky Way. The finding of metallic iron dust and silicon carbide (SiC) produced by aging stars, along with tiny clumps of carbon-based molecules, shows that even […]

A Dance of Galaxies

NASA’s James Webb Space Telescope captured two nearby dwarf galaxies interacting with each other in this image released on Dec. 2, 2025. Dwarf galaxies can give us insights into galaxies in the early universe, which were thought to have less mass than galaxies like the Milky Way, and also contain a lot of gas, relatively […]

NASA’s Webb Observes Exoplanet Whose Composition Defies Explanation

Scientists using NASA’s James Webb Space Telescope have observed a rare type of exoplanet, or planet outside our solar system, whose atmospheric composition challenges our understanding of how it formed.  Officially named PSR J2322-2650b, this Jupiter-mass object appears to have an exotic helium-and-carbon-dominated atmosphere unlike any ever seen before. Soot clouds likely float through the […]

NASA’s Webb, Curiosity Named in TIME’s Best Inventions Hall of Fame

Two icons of discovery, NASA’s James Webb Space Telescope and NASA’s Curiosity rover, have earned places in TIME’s “Best Inventions Hall of Fame,” which recognizes the 25 groundbreaking inventions of the past quarter century that have had the most global impact, since TIME began its annual Best Inventions list in 2000. The inventions are celebrated […]

NASA’s Webb Detects Thick Atmosphere Around Broiling Lava World 

Researchers using NASA’s James Webb Space Telescope have detected the strongest evidence yet for an atmosphere on a rocky planet outside our solar system, as NASA leads the world in exploring the universe from the Moon to Mars and beyond. Observations of the ultra-hot super-Earth TOI-561 b suggest that the exoplanet is surrounded by a […]
