NASA Webb, Hubble Reveal History of Relic of Milky Way’s Formation
Researchers using two of humanity’s most powerful observatories — NASA’s James Webb and Hubble Space Telescopes — have definitively shown that Terzan 5 is not a globular star cluster as it was once classified, offering new insight into how galaxies…

NASA Webb Finds Strongest Evidence Yet for ‘Black Hole Stars’
The complex puzzle known as little red dots has become more complete since their initial discovery by NASA’s James Webb Space Telescope in 2022. Now a particular little red dot’s spectrum is helping connect many of the pieces.

NASA’s Webb Reveals Black Hole That Formed Before Its Galaxy
Which comes first, the galaxy or the black hole? We don’t know, but scientists have long thought it could be the galaxy: Large stars within an existing galaxy consume their fuel and collapse to form black holes, which can gobble…

NASA’s Webb Redefines Dividing Line Between Planets, Stars
Planets, like those in our solar system, form in a bottom-up process where small bits of rock and ice clump together and grow larger over time. But the heftier the planet, the harder it is to explain its formation that…

NASA Webb, Hubble Share Most Comprehensive View of Saturn to Date
NASA’s James Webb Space Telescope and Hubble Space Telescope have teamed up to capture new views of Saturn, revealing the planet in strikingly different ways. Observing in complementary wavelengths of light, the two space observatories provide scientists with a richer,…

Artifacts From NASA’s Webb, Parker Solar Probe on View at Smithsonian
A testing replica of the “backbone” of NASA’s James Webb Space Telescope and a full-scale model of the agency’s Parker Solar Probe are now on permanent display at the Smithsonian’s National Air and Space Museum, Steven F. Udvar-Hazy Center in…

NASA’s Webb Examines Cranium Nebula
Two heads are better than one in the latest images from NASA’s James Webb Space Telescope, which reveal new detail in a mysterious, little-studied nebula surrounding a dying star. Nebula PMR 1 is a cloud of gas and dust that…

NASA’s Webb Telescope Locates Former Star That Exploded as Supernova
Forty million years ago, a star in a nearby galaxy exploded, spewing material across space and generating a brilliant beacon of light. That light traveled across the cosmos, reaching Earth June 29, 2025, where it was detected by the All-Sky…

NASA Webb Pushes Boundaries of Observable Universe Closer to Big Bang
NASA’s James Webb Space Telescope has topped itself once again, delivering on its promise to push the boundaries of the observable universe closer to cosmic dawn with the confirmation of a bright galaxy that existed 280 million years after the…

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…
