A water vapor plume from Saturn’s moon Enceladus spanning more than 6,000 miles – nearly the distance from Los Angeles, California to Buenos Aires, Argentina – has been detected by researchers using NASA’s James Webb Space Telescope.
Four composite images deliver dazzling views from NASA's Chandra X-ray Observatory and James Webb Space Telescope of two galaxies, a nebula, and a star cluster. Each image combines Chandra's X-rays — a form of high-energy light — with infrared data from previously released Webb images, both of which are invisible to the unaided eye.
The heart of NASA’s Nancy Grace Roman Space Telescope was recently delivered to Ball Aerospace for integration into the WFI (Wide Field Instrument). Called the FPS (Focal Plane System), it serves as the core of Roman’s camera.
Using Webb’s NIRSpec (Near-Infrared Spectrograph) instrument, astronomers have confirmed gas – specifically water vapor – around a comet in the main asteroid belt for the first time, indicating that water ice from the primordial solar system can be preserved in that region.
Awe-inspiring NASA visuals combined with the might of a live symphonic orchestra last week in “Cosmic Cycles,” a multimedia collaboration among the agency’s Goddard Space Flight Center in Greenbelt, Maryland, the National Philharmonic, and composer Henry Dehlinger.
Astronomers used NASA’s James Webb Space Telescope to image the warm dust around a nearby young star, Fomalhaut, in order to study the first asteroid belt ever seen outside of our solar system in infrared light.
Astronomers used NASA’s James Webb Space Telescope to study a rocky exoplanet known as GJ 486 b, and their observations using Webb’s Near-Infrared Spectrograph (NIRSpec) show hints of water vapor.
The primary structure that serves as the “bones” of NASA’s Nancy Grace Roman Space Telescope just moved into the clean room at the Goddard Space Flight Center. The rest of the spacecraft will be built up on this skeletal structure.
NASAs James Webb Space Telescope has confirmed, for the first time, a protocluster of seven galaxies at a distance that astronomers refer to as redshift 7.9, or a mere 650 million years after the big bang.
Vice President Kamala Harris and Republic of Korea (ROK) President Yoon Suk Yeol will visit NASA’s Goddard Space Flight Center in Greenbelt, Maryland, on Tuesday, April 25, to see firsthand the agency’s climate change work. NASA Deputy Administrator Pam Melroy and Goddard Center Director Makenzie Lystrup will join them on tour.
Astronomers are celebrating NASA's Hubble Space Telescope's 33rd launch anniversary with an ethereal photo of a nearby star-forming region, NGC 1333. The nebula is in the Perseus molecular cloud, and located approximately 960 light-years away.
A vital subsystem for NASA’s Nancy Grace Roman Space Telescope was recently installed in the spacecraft’s Wide Field Instrument. Called the Simplified Relative Calibration System (sRCS), this component will allow astronomers to measure the total light output of cosmic objects like galaxies and supernovae with extreme accuracy.
Shining like a brilliant beacon amidst a sea of galaxies, Arp 220 lights up the night sky in this view from NASA’s James Webb Space Telescope. Actually two spiral galaxies in the process of merging, Arp 220 glows brightest in infrared light, making it an ideal target for Webb.
A new mid-infrared image from NASA’s James Webb Space Telescope shows the supernova remnant Cassiopeia A (Cas A), created by a stellar explosion seen from Earth 340 years ago. Cas A is the youngest known remnant from an exploding, massive star in our galaxy.
Following in the footsteps of the Neptune image released in 2022, NASA’s James Webb Space Telescope has taken a stunning image of the solar system’s other ice giant, the planet Uranus. The new image features dramatic rings as well as bright features in the planet’s atmosphere.
On Sunday, Oct. 9, 2022, a pulse of intense radiation swept through the solar system so exceptional that astronomers quickly dubbed it the BOAT – the brightest of all time. After spending months combing through the data, astronomers now better understand its scientific impact.
Researchers observing with NASA’s James Webb Space Telescope have pinpointed silicate cloud features in a distant planet’s atmosphere. The team, led by Brittany Miles of the University of Arizona, also made extraordinarily clear detections of water, methane and carbon monoxide with Webb’s data, and found evidence of carbon dioxide.
The rare sight of a Wolf-Rayet star – among the most luminous, most massive, and most briefly detectable stars known – was one of the first observations made by NASA’s James Webb Space Telescope in June 2022.
Scientists have created a gargantuan synthetic survey that shows what we can expect from the Nancy Grace Roman Space Telescope’s future observations. Though it represents just a small chunk of the real future survey, this simulated version contains a staggering number of galaxies – 33 million, along with 200,000 foreground stars in our home galaxy.
A new simulation shows how NASA’s Nancy Grace Roman Space Telescope will turn back the cosmic clock, unveiling the evolving universe in ways that have never been possible before.
Researchers using NASA’s James Webb Space Telescope are getting their first look at star formation, gas, and dust in nearby galaxies with unprecedented resolution at infrared wavelengths.
