NASA’s Webb Snaps Supersonic Outflow of Young Star

NASA’s James Webb Space Telescope’s high resolution, near-infrared look at Herbig-Haro 211 reveals exquisite detail of the outflow of a young star, an infantile analogue of our Sun. Herbig-Haro objects are formed when stellar winds or jets of gas spewing from newborn stars form shock waves colliding with nearby gas and dust at high speeds. The image showcases a series of bow shocks to the southeast (lower-left) and northwest (upper-right) as well as the narrow bipolar jet that powers them in unprecedented detail. Molecules excited by the turbulent conditions, including molecular hydrogen, carbon monoxide and silicon monoxide, emit infrared light, collected by Webb, that map out the structure of the outflows.

Explanation: Do stars always create jets as they form? No one is sure. As a gas cloud gravitationally contracts, it forms a disk that can spin too fast to continue contracting into a protostar. Theorists hypothesize that this spin can be reduced by expelling jets. This speculation coincides with known Herbig-Haro (HH) objects, young stellar objects seen to emit jets -- sometimes in spectacular fashion. Pictured is Herbig-Haro 211, a young star in formation recently imaged by the Webb Space Telescope (JWST) in infrared light and in great detail. Along with the two narrow beams of particles, red shock waves can be seen as the outflows impact existing interstellar gas. The jets of HH 221 will likely change shape as they brighten and fade over the next 100,000 years, as research into the details of star formation continues.

Discovery Alert! In a new discovery released on September 14, 2023, James Webb Telescope reveals A Close-Up of Stellar Birth in HH 211. Read full article here

Prepare to be captivated by the breathtaking beauty of space! NASA's James Webb Space Telescope has gifted us with a mesmerizing glimpse into the birth of celestial bodies, courtesy of Herbig-Haro 211 (HH 211). This cosmic wonder resembles the early days of our own Sun and offers invaluable insights into star formation.

🌟 Herbig-Haro objects are cosmic masterpieces born when stellar winds and gas jets from newborn stars collide with nearby interstellar matter at astonishing speeds. In Webb's high-resolution, near-infrared image, HH 211 shines with exquisite detail, showcasing a series of dazzling bow shocks to the southeast and northwest. But that's not all—this image unveils a slender bipolar jet that powers these shocks in unprecedented detail.

💫 What makes this image even more fascinating is the dance of molecules within this turbulent environment. Molecular hydrogen, carbon monoxide, silicon monoxide, and more become electrified, emitting infrared light that Webb artfully captures. This light provides a map of the intricate structure of the celestial outflows.

Webb captures a prominent protostar in Perseus

This new Picture of the Month from the NASA/ESA/CSA James Webb Space Telescope reveals intricate details of the Herbig Haro object 797 (HH 797). Herbig-Haro objects are luminous regions surrounding newborn stars (known as protostars), and are formed when stellar winds or jets of gas spewing from these newborn stars form shockwaves colliding with nearby gas and dust at high speeds.

HH 797, which dominates the lower half of this image, is located close to the young open star cluster IC 348, which is located near the eastern edge of the Perseus dark cloud complex. The bright infrared objects in the upper portion of the image are thought to host two further protostars.

This image was captured with Webb's Near-InfraRed Camera (NIRCam). Infrared imaging is powerful in studying newborn stars and their outflows, because the youngest stars are invariably still embedded within the gas and dust from which they are formed. The infrared emission of the star's outflows penetrates the obscuring gas and dust, making Herbig-Haro objects ideal for observation with Webb's sensitive infrared instruments.

Molecules excited by the turbulent conditions, including molecular hydrogen and carbon monoxide, emit infrared light that Webb can collect to visualize the structure of the outflows. NIRCam is particularly good at observing the hot (thousands of degrees Celsius) molecules that are excited as a result of shocks.

Using ground-based observations, researchers have previously found that for the cold molecular gas associated with HH 797, most of the red-shifted gas (moving away from us) is found to the south (bottom right), while the blue-shifted gas (moving towards us) is to the north (bottom left). A gradient was also found across the outflow, such that at a given distance from the young central star, the velocity of the gas near the eastern edge of the jet is more red-shifted than that of the gas on the western edge.

Astronomers in the past thought this was due to the outflow's rotation. In this higher-resolution Webb image, however, we can see that what was thought to be one outflow is in fact made up of two almost parallel outflows with their own separate series of shocks (which explains the velocity asymmetries). The source, located in the small dark region (bottom right of center), and already known from previous observations, is therefore not a single but a double star. Each star is producing its own dramatic outflow. Other outflows are also seen in this image, including one from the protostar in the top right of center along with its illuminated cavity walls.

HH 797 resides directly north of HH 211 (separated by approximately 30 arcseconds), which was the feature of a Webb image release in September 2023.

IMAGE....In the lower half of the image is a narrow, horizontal nebula that stretches from edge to edge. It is brightly colored with more variety on its right side. In the upper half there is a glowing point with multi-colored light radiating from it in all directions. A bright star with long diffraction spikes lies along the right edge, and a few smaller stars are spread around. The background is covered in a thin haze. Credit: ESA/Webb, NASA & CSA, T.
