James Webb Space Telescope
Webb is the premier observatory of the next decade, serving thousands of astronomers worldwide. It studies every phase in the history of our Universe.
Key Facts
Featured Image/Article
Astronomers have long tried to track down how elements like carbon, which is essential for life, become widely distributed across the universe. Now, NASA’s James Webb Space Telescope has examined one ongoing source of carbon-rich dust in our own Milky Way galaxy in greater detail: Wolf-Rayet 140, a system of two massive stars that follow a tight, elongated orbit.
As they swing past one another (within the central white dot in the Webb images), the stellar winds from each star slam together, the material compresses, and carbon-rich dust forms. Webb’s latest observations show 17 dust shells shining in mid-infrared light that are expanding at regular intervals into the surrounding space.

Webb Watches Carbon-Rich Dust Shells Form, Expand in Star System
Astronomers have long tried to track down how elements like carbon, which is essential for life, become widely distributed across the universe. Now, NASA’s James Webb Space Telescope has examined one ongoing source of carbon-rich dust in our own Milky…
NASA Research To Be Featured at American Astronomical Society Meeting
From new perspectives on the early universe to illuminating the extreme environment near a black hole, discoveries from NASA missions will be highlighted at the 245th meeting of the American Astronomical Society (AAS). The meeting will take place Jan. 12-16…
NASA’s Webb Finds Planet-Forming Disks Lived Longer in Early Universe
NASA’s James Webb Space Telescope just solved a conundrum by proving a controversial finding made with the agency’s Hubble Space Telescope more than 20 years ago. In 2003, Hubble provided evidence of a massive planet around a very old star,…
NASA Successfully Integrates Roman Mission’s Telescope, Instruments
NASA’s Nancy Grace Roman Space Telescope team has successfully integrated the mission’s telescope and two instruments onto the instrument carrier, marking the completion of the Roman payload. Now the team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, will…
Webb's Latest Blog
Webb's Blog offers an insider's point of view covering a variety of topics that include on going operations as well as exciting Webb science images/spectra that are not yet peer reviewed and therefore not released as NASA feature articles ( IE the above official Webb News Feed). Blog posts are often co-authored by scientists and engineers and offer unique insights.

The James Webb Space Telescope is a giant leap forward in our quest to understand the Universe and our origins. Webb is examining every phase of cosmic history: from the first luminous glows after the Big Bang to the formation of galaxies, stars, and planets to the evolution of our own solar system. Learn about the 4 main science themes for Webb.

The Webb Space Telescope is the largest, most powerful and most complex telescope ever launched into space . It's design and development history stretches back before the Hubble Space Telescope was launched. Learn about the design, the major components and subsystems of Webb and see Webb in 3d in a 3d Solar System.
Learn MoreThe International Webb Team
Webb is for the world, and from the world. Thousands of skilled scientists, engineers and technicians from 14 countries (and more than 29 U.S. states, and Washington, D.C.) contributed to the design, build, test, integration, launch, commissioning and operations of Webb. It is a joint NASA/ESA/CSA mission. Assembly and testing of the mirror and instruments occurred at NASA Goddard (GSFC).
