Red Spider Nebula

Using its Near-InfraRed Camera (NIRCam), NASA’s James Webb Space Telescope captured never-before-seen details of the Red Spider Nebula, a planetary nebula, in this image released on Oct. 26, 2025. NIRCam is Webb’s primary near-infrared imager, providing high-resolution imaging and spectroscopy for a wide variety of investigations.

View Interstellar Comet 3I/ATLAS Through NASA’s Multiple Lenses 

This article was updated to include the full range of dates from the SOHO image. Lee esta historia en español aquí. NASA is in the midst of an unprecedented solar system-wide observation campaign, turning its spacecraft and space telescopes to follow comet 3I/ATLAS, the third known interstellar object to pass through our solar system. Twelve […]

Webb First to Show 4 Dust Shells ‘Spiraling’ Apep, Limits Long Orbit

NASA’s James Webb Space Telescope has delivered a first of its kind: a crisp mid-infrared image of a system of four serpentine spirals of dust, one expanding beyond the next in precisely the same pattern. (The fourth is almost transparent, at the edges of Webb’s image.) Observations taken prior to Webb only detected one shell, […]

Mapping Dark Matter

This image released on June 30, 2025, combines data from NASA’s James Webb Space Telescope and NASA’s Chandra X-ray Observatory to visualize dark matter. Researchers used Webb’s observations to carefully measure the mass of the galaxy clusters shown here as well as the collective light emitted by stars that are no longer bound to individual […]

NASA’s Webb Explores Largest Star-Forming Cloud in Milky Way

NASA’s James Webb Space Telescope has revealed a colorful array of massive stars and glowing cosmic dust in the Sagittarius B2 molecular cloud, the most massive and active star-forming region in our Milky Way galaxy.  “Webb’s powerful infrared instruments provide detail we’ve never been able to see before, which will help us to understand some […]

NASA’s Webb Observes Immense Stellar Jet on Outskirts of Our Milky Way

A blowtorch of seething gasses erupting from a volcanically growing monster star has been captured by NASA’s James Webb Space Telescope. Stretching across 8 light-years, the length of the stellar eruption is approximately twice the distance between our Sun and the next nearest stars, the Alpha Centauri system.

NASA Study: Celestial ‘Accident’ Sheds Light on Jupiter, Saturn Riddle

An unusual cosmic object is helping scientists better understand the chemistry hidden deep in Jupiter and Saturn’s atmospheres — and potentially those of exoplanets. Why has silicon, one of the most common elements in the universe, gone largely undetected in the atmospheres of Jupiter, Saturn, and gas planets like them orbiting other stars?

NASA Webb Looks at Earth-Sized, Habitable-Zone Exoplanet TRAPPIST-1 e

Scientists are in the midst of observing the exoplanet TRAPPIST-1 e with NASA’s James Webb Space Telescope. Careful analysis of the results so far presents several potential scenarios for what the planet’s atmosphere and surface may be like, as NASA science missions lay key groundwork to answer the question, “are we alone in the universe?”  […]

NASA’s Webb Scratches Beyond Surface of Cat’s Paw for 3rd Anniversary

It’s the cat’s meow! To celebrate its third year of revealing stunning scenes of the cosmos in infrared light, NASA’s James Webb Space Telescope has “clawed” back the thick, dusty layers of a section within the Cat’s Paw Nebula (NGC 6334). Focusing Webb’s NIRCam (Near-Infrared Camera) on a single “toe bean” within this active star-forming […]
