JWST Spies Once-hidden Treasures in the W51 Starbirth Crèche

Star formation is a dramatic and complex process that erupts throughout the Universe. Yet, a lot of the action gets hidden by clouds of gas and dust. That's where observatories suc...

Where's the Dividing Line Between A Star and A Planet? Ask the JWST.

It's obvious that Earth is a planet. It's obvious that the Sun is a star. But for substellar objects like brown dwarfs, it's not so clear. Researchers are using the JWST to find a...

JWST Studies a Dark and Airless Super-Earth

There's a planet out there called LHS 3844 b, orbiting a star about 48 light-years away. The Transiting Exoplanet Survey Satellite (TESS) found it in 2018 when the planet transited...

Astronomers find an exo-Jupiter, and it seems to have clouds

JWST studied a massive Jupiter-like exoplanet's atmosphere, finding surprising water-ice clouds that simpler models missed - a key test run for future Earth-like world searches.

James Webb Telescope Reveals the Universe’s Hidden Cosmic Web in Stunning Detail

JWST has unveiled the sharpest-ever map of the universe’s hidden cosmic web, reaching back nearly to cosmic dawn. Astronomers using NASA’s James Webb Space Telescope (JWST) have cr...

JWST maps cosmic web in record detail back to universe's first billion years

Using data from NASA's James Webb Space Telescope (JWST), astronomers led by researchers at the University of California, Riverside have produced the most detailed map of the cosmi...

Webb eyes a pair of planet-forming disks

This month's NASA/ESA/CSA James Webb Space Telescope Picture of the Month offers us a two-for-one on brand new stars—with some potential planets thrown in as well. This visual hi...

ALMA and JWST investigate giant disk galaxy's formation and evolution

European astronomers have used the Atacama Large Millimeter Array (ALMA) and the James Webb Space Telescope (JWST) to observe a recently discovered giant disk galaxy known as ADF22...

New JWST images reveal cosmic question marks and buckyballs in a planetary nebula

New James Webb Space Telescope images could shed fresh light on how dying stars evolve over time

JWST spots methane on a giant exoplanet, but its star may be distorting the signal

Using the James Webb Space Telescope (JWST), astronomers from Johns Hopkins University (JHU) and elsewhere have observed a giant exoplanet known as HATS-75 b. Results of the new ob...

This Alien Planet Has Rock Clouds That Vaporize Before Sunset

JWST has revealed a surprising daily cloud cycle on a distant hot Jupiter, giving scientists a clearer look at its atmosphere. On WASP-94A b, the forecast changes fast. Clouds made...

New NASA Telescope = Hubba Hubba

JWST sees partly cloudy skies on a distant, giant exoplanet

An out-of-this-world weather report from NASA’s James Webb Space Telescope reveals how clouds move across a giant planet hundreds of light-years from Earth

JWST maps the weather on a hot gas giant 700 light-years away

The differences seen here could be throwing off how we study planetary atmospheres.

This exoplanet weather forecast by the James Webb Space Telescope calls for sandy skies and a clear (alien) sunset

Thanks to the James Webb Space Telescope, astronomers have witnessed a cloudy morning dissipating to leave a clear sky by dusk on a distant hot Jupiter.

NASA’s Webb Space Telescope Reveals a Dark Airless Super-Earth That Looks Like Mercury

A nearby “super-Earth” is giving scientists a rare look at the bare surface of a distant world, and it’s far from Earth-like. Using MIRI (Mid Infrared Instrument) on board the Jame...

JWST pins down the origins of a planetary odd couple

Across the Milky Way galaxy, a planetary odd couple is circling a star some 190 light years from Earth. A normally "lonely" hot Jupiter is sharing space with a mini-Neptune, in a r...

James Webb telescope captures star formation "factory" in fine detail

Westerhaut 51 is the unassuming name of a vast "star factory" 17,000 light years from Earth. 350 light years across, it contains numerous O-type stars, the rarest on the main seque...

James Webb Space Telescope peers into a dying star surrounded by mysterious buckyballs: 'The structures we're seeing now...

The James Webb Space Telescope captured the first detailed images of planetary nebula Tc 1, revealing new details of what happens after a sun-like star dies.

James Webb Space Telescope Brings Details Of Nearby 'Super-Earth' Into Focus

This one telescope is enabling us to deduce not just the chemical and mineral compositions of distant worlds, but their terrain and features as well.

Both Hemispheres of 3I/ATLAS Observed Simultaneously by JUICE and Europa Clipper

The Southwest Research Institute-led Ultraviolet Spectrograph (UVS) instruments aboard ESA’s Jupiter Icy Moons Explorer (Juice) spacecraft and NASA’s Europa Clipper made unique obs...

Astronomers explore the surface composition of a nearby super-Earth

Using MIRI (Mid-Infrared Instrument) on board the James Webb Space Telescope (JWST), a team of researchers led by former MPIA (Max Planck Institute for Astronomy, Heidelberg, Germa...
