NASA's James Webb Space Telescope shows off its capabilities closer to home with its first image of Neptune. Not only has Webb captured the clearest view of this distant planet's rings in more than 30 years, but its cameras reveal the ice giant in a whole new light. Most striking in Webb's new image is the crisp view of the planet's rings – some of which have not been detected since NASA's Voyager 2 became the first spacecraft to observe Neptune during its flyby in 1989. In addition to several bright, narrow rings, the Webb image clearly shows Neptune’s fainter dust bands. Webb’s Near-Infrared Camera (NIRCam) image of Neptune, taken on July 12, 2022, brings the planet’s rings into full focus for the first time in more than three decades.

An international research team will survey the stars, star clusters, and dust that lie within 19 nearby galaxies Spirals are some of the most captivating shapes in the universe. They appear in intricate seashells, carefully constructed spider webs, and even in the curls of ocean waves. Spirals on cosmic scales – as seen in galaxies – are even more arresting, not only for their beauty, but also for the overwhelming amount of information they contain. How do stars and star clusters form? Until recently, a complete answer used to lie out of reach, blocked by gas and dust. 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.

NASA's James Webb Space Telescope, built to give the world its first glimpse of the universe as it existed when the earliest galaxies formed, was launched by rocket early Saturday from the northeastern coast of South America, opening a new era of astronomy. The revolutionary $9 billion infrared telescope, described by NASA as the premiere space-science observatory of the next decade, was carried aloft inside the cargo bay of an Ariane 5 rocket that blasted off at about 7:20 a.m. EST (1220 GMT) from the European Space Agency's (ESA) launch base in French Guiana. Arianespace's Ariane 5 rocket, with NASA’s James Webb Space Telescope onboard, launches from Europe’s Spaceport, the Guiana Space Center in Kourou, French Guiana December 25, 2021 in a still image from video.
