| Description |
Webb scientists uncovered “buried treasure,” and the Cosmic Cliffs marked the spot. ☠️ You might remember this view, taken in the Carina Nebula, as part of Webb’s first images released. A deep dive into the data has newly revealed a hotbed of young stars in an elusive stage of development. This discovery may help us investigate how stars like our Sun form, as well as how radiation from nearby massive stars might affect the development of planets. Webb was able to detect the signatures of extremely young stars, never before seen. Stars at this early stage of development are hidden inside clouds of dust and gas, and are only visible in infrared light and with high resolution instruments. These young stars interact with their environments by taking in material and then ejecting some of it. The ejections, in the form of jets and outflows of matter, heat the surrounding hydrogen gas (H2, or molecular hydrogen), causing it to emit light.

Koekemoer (STScI) In this image: Insets on the right-hand side highlight three regions of the Cosmic Cliffs with particularly active molecular hydrogen outflows. Image description: The image is split into 4 boxes. On the left is a large box that takes up half of the full image. On the right are 3 boxes (2 boxes split vertically at the top, the third across the bottom). The right boxes are enlarged areas of the left image, labeled 1, 2, and 3 respectively, and are indicated by corresponding white outlines on the left image. The left image is divided horizontally by an undulating line between a cloudscape forming a nebula along the bottom and a comparatively clear upper portion. Speckled across both portions is a starfield. The upper portion of the image is blueish, and has wispy translucent cloud-like streaks rising from the nebula below. The orangish cloud-like structure of the nebula contains ridges, peaks, and valleys. The 3 pull-out images are close-ups of bright red, elongated splotches within the cloud, labeled as molecular hydrogen outflows. In box 2, a roughly horizontal line that ends in 2 c-shaped curves, labeled jet and bow shocks, is superimposed. |
