As interstellar comet 3I/ATLAS began moving away from the Sun in December 2025, astronomers took the opportunity to turn NASA’s powerful James Webb Space Telescope in its direction and capture detailed measurements of its chemical components. The comet was freshly warmed from its closest pass by the Sun, and its ancient ice had been converted […]

This image, captured by NASA’s James Webb Space Telescope and released on June 5, 2026, shows just a small portion of one of the Orion Molecular Clouds, a long and massive filament of cold gas and dust beyond the Orion Nebula. Every stage of star formation — from the youngest stellar embryos to protoplanetary discs […]

That’s the latest from researchers analyzing NASA’s James Webb Space Telescope’s observations of HD 80606 b, an exoplanet four times the mass of Jupiter with an extremely elliptical orbit that sweeps close by its Sun-like star.

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 like our own form and evolve over time. A globular star cluster typically has only […]

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 up surrounding material and merge over time to form more massive entities. But it’s hard […]

This near-infrared image released on May 6, 2026, shows a section of one of the spiral arms of Messier 51 (M51). M51 is one of four nearby galaxies observed by NASA’s James Webb Space Telescope in a study of nearly 9,000 star clusters. Data from the study shows that more massive star clusters emerge more […]

The heart of galaxy M77 shines brightly in this May 7, 2026, image from NASA’s James Webb Space Telescope. The intense glow is due to gas being pulled by the strong gravity of the central black hole into a tight and rapid orbit around it. The motion of the gas causes it to heat up, […]

The interstellar comet 3I/ATLAS will soon leave our solar system, never to return, but the observations of the comet will live on in NASA’s public data archives. More than a dozen NASA science missions turned their instruments to observe the comet, which is only the third identified object to be visiting our solar system from […]
