Webb Captures Stellar Gymnastics in The Cartwheel Galaxy

NASA’s James Webb Space Telescope has peered into the chaos of the Cartwheel Galaxy, revealing new details about star formation and the galaxy’s central black hole. Webb’s powerful infrared gaze produced this detailed image of the Cartwheel and two smaller companion galaxies against a backdrop of many other galaxies.

Gravity Assist: Meet a Webb Scientist Who Looks Back in Time

The James Webb Space Telescope awed the world on July 12 with its first images and data. And it’s just getting started with its exploration of the cosmos. Dr. John Mather, the observatory’s senior project scientist, has been working toward this milestone for more than 25 years.

NASA’s Webb Reveals Steamy Atmosphere of Distant Planet in Detail

NASA's James Webb Space Telescope captured the most detailed measurements of starlight filtering through the atmosphere of a planet outside our solar system to date. Distinct water signatures were observed, as was evidence of haze and clouds that previous studies did not detect.

NASA’s Webb Captures Dying Star’s Final ‘Performance’ in Fine Detail

NASA’s James Webb Space Telescope has revealed details of the Southern Ring planetary nebula that were previously hidden from astronomers. Planetary nebulae are the shells of gas and dust ejected from dying stars.

NASA’s Webb Sheds Light on Galaxy Evolution, Black Holes

The new image of galaxy group "Stephan's Quintet" from NASA's James Webb Space Telescope shows in rare detail how interacting galaxies trigger star formation in each other and how gas in galaxies is being disturbed. The image also shows outflows driven by a black hole in Stephan’s Quintet in a level of detail never seen before.

NASA’s Webb Reveals Cosmic Cliffs, Glittering Landscape of Star Birth

This landscape of “mountains” and “valleys” speckled with glittering stars is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. Captured in infrared light by NASA’s new James Webb Space Telescope, this image reveals for the first time previously invisible areas of star birth.

NASA’s Webb Delivers Deepest Infrared Image of Universe Yet

NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail.

NASA Shares List of Cosmic Targets for Webb Telescope’s First Images

NASA’s James Webb Space Telescope will soon reveal unprecedented and detailed views of the universe, with the release of its first full-color images and spectroscopic data. The targets, selected by an international committee, will be released July 12: Carina Nebula, WASP-96 b (spectrum), Southern Ring Nebula, Stephan's Quintet, and SMACS 0723.

NASA’s Webb to Uncover Riches of the Early Universe

NASA’s next flagship observatory, the James Webb Space Telescope, is poised to add new riches to our wealth of knowledge not only by capturing images from galaxies that existed as early as the first few hundred million years after the big bang, but also by giving us detailed data known as spectra.

NASA’s Astronomy Picture of the Day Recognized for Decades of Outreach

NASA's APOD has been honored by the International Astronomical Union for decades of outreach.

NASA Telescope to Help Untangle Galaxy Growth, Dark Matter Makeup

NASA’s Nancy Grace Roman Space Telescope will study wispy streams of stars that extend far beyond the edges of many galaxies. Astronomers will use these observations to explore how galaxies grow and the nature of dark matter.

First Images From NASA’s Webb Space Telescope Coming Soon

NASA’s James Webb Space Telescope, a partnership with ESA (European Space Agency) and the Canadian Space Agency (CSA), will release its first full-color images and spectroscopic data on July 12, 2022.

Geology from 50 Light-Years: Webb Gets Ready to Study Rocky Worlds

Researchers will train Webb’s high-precision spectrographs on two intriguing rocky exoplanets.

NASA Goddard Astrophysicist Awarded 2022 LGBTQ+ Scientist of the Year

Dr. Jane Rigby, an astrophysicist at the NASA Goddard Flight Center in Greenbelt, Maryland was recently awarded 2022 LGBTQ+ Scientist of the Year by Out to Innovate.

Webb Telescope’s Coldest Instrument Reaches Operating Temperature

NASA’s James Webb Space Telescope will see the first galaxies to form after the big bang, but to do that its instruments first need to get cold – really cold. On April 7, Webb’s Mid-Infrared Instrument (MIRI) – a joint development by NASA and ESA (European Space Agency) – reached its final operating temperature below 7 kelvins.

NASA’s Roman Mission Will Test Competing Cosmic Acceleration Theories

NASA’s Nancy Grace Roman Space Telescope will analyze millions of galaxies strewn across space and time. The mission’s enormous, deep panoramas will provide the best opportunity yet to discern between the leading theories about what’s speeding up the universe’s expansion.

How NASA’s Roman Could Help Find Other Earths by Surveying Space Dust

A team of scientists has found that NASA's Roman Space Telescope will be able to measure a specific kind of space dust littered throughout the habitable zones of 74 nearby planetary systems. Finding out how much of this material these systems contain would help astronomers learn more about planet formation and guide the search for habitable worlds.

NASA’s Webb Reaches Alignment Milestone, Optics Working Successfully

Following the completion of critical mirror alignment steps, NASA’s James Webb Space Telescope team expects that Webb’s optical performance will be able to meet or exceed the science goals the observatory was built to achieve.

NASA Invites Media to 59th Annual Robert H. Goddard Memorial Symposium

Media are invited to meet leaders in space exploration at the 59th annual Robert H. Goddard Memorial Symposium, taking place on the campus of the University of Maryland, College Park, from March 23 to 25. Attendees also have the option to watch the symposium online.

Studying the Next Interstellar Interloper with Webb

One of the most exciting findings in planetary science in recent years is the discovery of interstellar objects passing through our solar system. So far, astronomers have confirmed only two of these interlopers from other star systems — 1I/'Oumuamua in 2017 and 2I/Borisov in 2018 — but many, many more are thought to exist.

Capturing All That Glitters in Galaxies With NASA’s Webb

Within the first year of operations, NASA’s James Webb Space Telescope will help researchers complete a more detailed sketch of the stellar life cycle with high-resolution infrared-light images of 19 galaxies.

One Year into the Biden Administration, NASA Looks to Future

Over the past year, NASA has made valuable contributions to Biden-Harris Administration’s goals – leading on the global stage, addressing the urgent issue of climate change, creating high paying jobs, and inspiring future generations.

Simulated Image Shows How NASA’s Roman Could Expand on Hubble’s Deepest View

A team of astrophysicists has created a simulated image that shows how the Nancy Grace Roman Space Telescope could conduct a mega-exposure similar to but far larger than Hubble’s celebrated Ultra Deep Field Image.
