The first anniversary image from NASA’s James Webb Space Telescope displays star birth like it’s never been seen before, full of detailed, impressionistic texture. The subject is the Rho Ophiuchi cloud complex, the closest star-forming region to Earth. It is a relatively small, quiet stellar nursery, but you’d never know it from Webb’s chaotic close-up. Jets bursting from young stars crisscross the image, impacting the surrounding interstellar gas and lighting up molecular hydrogen, shown in red. Some stars display the telltale shadow of a circumstellar disk, the makings of future planetary systems. The young stars at the center of many of these disks are similar in mass to the Sun, or smaller. The heftiest in this image is the star S1, which appears amid a glowing cave it is carving out with its stellar winds in the lower half of the image. The lighter-colored gas surrounding S1 consists of polycyclic aromatic hydrocarbons, a family of carbon-based molecules that are among the most common compounds found in space. For more detail on what is happening where in Webb’s image of Rho Ophiuchi, watch the video tour and read the press release.

What looks like craggy mountains in moonlight is actually the edge of NGC 3324, a young star-forming region in the Carina Nebula, captured in infrared by Webb's NIRCam. Nicknamed the "Cosmic Cliffs," the region is the edge of a gigantic cavity carved by intense ultraviolet radiation and stellar winds from hot, massive young stars, revealing hundreds of previously hidden stars and background galaxies for the first time.

To celebrate NASA’s James Webb Space Telescope’s third year of highly productive science, astronomers used the telescope to scratch beyond the surface of the Cat’s Paw Nebula (NGC 6334), a massive, local star-forming region. This area is of great interest to scientists, having been subject to previous study by NASA’s Hubble and retired Spitzer space telescopes, as they seek to understand the multiple steps required for a turbulent molecular cloud to transition to stars. With its near-infrared capabilities and sharp resolution, the telescope “clawed” back a portion of a singular “toe bean,” revealing a subset of mini toe bean-reminiscent structures composed of gas, dust, and young stars. Webb’s view reveals a chaotic scene still in development: Massive young stars are carving away at nearby gas and dust, while their bright starlight is producing a bright nebulous glow represented in blue. This is only a chapter in the region’s larger story. The disruptive young stars, with their relatively short lifespans and luminosity, will eventually quench the local star formation process. The Cat’s Paw Nebula is located approximately 4,000 light-years away in the constellation Scorpius. To dive deeper into Webb’s image of the Cat’s Paw, embark on a narrated tour, get closer to the image, or read the press release.
