This collage compares images of the Flame Nebula: the left shows a near-infrared view from NASA's Hubble Space Telescope, while the right features near-infrared images from NASA's James Webb Space Telescope, revealing a more translucent cloud and highlighting young stars and brown dwarfs. Webb’s images offer a deeper look into this star-forming region. The Flame Nebula, located approximately 1,400 light-years from Earth, is a vibrant and dynamic region where stars are still in the process of being born. Within this cosmic nursery, astronomers have discovered objects that are too small to ignite hydrogen fusion—the defining characteristic of stars—called brown dwarfs. These so-called “failed stars” are cooler and dimmer than full-fledged stars, which makes them notoriously hard to detect, especially from vast distances. However, when these brown dwarfs are young, they are still relatively bright and warm, making them easier to observe, even through the dense dust and gas that ...
Shimmering ejections from two forming stars shape Lynds 483 (L483), with NASA's James Webb Space Telescope revealing stunning new details, including asymmetrical lines that intersect, located 650 light-years away in the constellation Serpens. NASA’s James Webb Space Telescope has captured extraordinary new images of Lynds 483 (L483), a star-forming region located within a vast molecular cloud. These high-resolution near-infrared images offer unprecedented views of two actively forming stars at the heart of the nebula. Their luminous ejections of gas and dust, visible in a stunning blend of orange, blue, and purple hues, have been intricately revealed by Webb’s powerful instruments. Over tens of thousands of years, these central protostars have periodically expelled dense gas and dust in the form of tight, fast jets and slightly slower outflows. When more recent ejections collide with older material, the interaction creates intricate patterns of crumpling and twisting. This proces...
