A dark starfield is dominated by a red cone-like nebula with its base on the bottom right and extending diagonally through the image. At the peak of the cone toward the upper left is a background spiral galaxy. Please see the explanation for more detailed information.
一片暗淡的星场被一个红色的锥形星云所笼罩，其底部位于右下方，并沿对角线延伸穿过图像。在圆锥顶端的左上方是一个螺旋星系背景。有关更多详细信息，请参阅说明。

A dark field has a single, colorful, blurry structure in its center. Red-colored jets extend out from the center toward the top and bottom of the frame. A dark disk covers the center. Blue outflows appear on both sides of the horizontal disk. To the lower left, a larger blue outflow extends. Please see the explanation for more detailed information.
暗场中央有一个单一的、色彩鲜艳的模糊结构。红色喷流从中心向画面的顶部和底部延伸。一个暗盘覆盖了中心。水平盘的两侧出现蓝色外流。在左下方，有一个更大的蓝色外流延伸。有关更多详细的信息，请参阅说明。

2023年9月19日 HH 211: Jets from a Forming Star Credit: NASA, ESA, CSA, Webb; Processing: Tom Ray (DIAS Dublin) 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…
2023年7月28日 Young Stars, Stellar Jets Image Credit: NASA, ESA, CSA, Processing: Joseph DePasquale (STScI) Explanation: High-speed outflows of molecular gas from a pair of actively forming young stars shine in infrared light, revealing themselves in this NIRcam image from the James Webb Space Telescope. Cataloged as HH (Herbig-Haro) 46/47, the young stars are lodged within a dark nebula that is largely opaque when viewed in visible light. The pair lie at the center of the prominent reddish diffraction spikes in the NIRcam image. Their energetic stellar jets extend for nearly a light-year, burrowing into the dark interstellar material. A tantalizing object to explore with Webb’s infrared capabilities, this young star system is relatively nearby, located only some 1,140 light-years distant in the nautical constellation Vela….
2021年8月4日 EHT Resolves Central Jet from Black Hole in Cen A Image Credit: Radboud University; CSIRO/ATNF/I.Feain et al., R.Morganti et al., N.Junkes et al.; ESO/WFI; MPIfR/ESO/APEX/A. Weiss et al.; NASA/CXC/CfA/R. Kraft et al.; TANAMI/C. Mueller et al.; EHT/M. Janssen et al. Explanation: How do supermassive black holes create powerful jets? To help find out, the Event Horizon Telescope (EHT) imaged the center of the nearby active galaxy Centaurus A. The cascade of featured inset images shows Cen A from it largest, taking up more sky than many moons, to its now finest, taking up only as much sky as an golf ball on the moon. The new image shows what may look like two jets — but is actually two sides of a single jet….
2021年06月23日 STARFORGE: A Star Formation Simulation Video & Text Credit: Michael Y. Grudić (Northwestern U.) et al., STARFORGE Collaboration; Music: Prelude, Op. 28, No. 4 in E Minor (Frédéric Chopin) Explanation: How do stars form? Most form in giant molecular clouds located in the central disk of a galaxy. The process is started, influenced, and limited by the stellar winds, jets, high energy starlight, and supernova explosions of previously existing stars. The featured video shows these complex interactions as computed by the STARFORGE simulation of a gas cloud 20,000 times the mass of our Sun. In the time-lapse visualization, lighter regions indicate denser gas, color encodes the gas speed (purple is slow, orange is fast), while dots indicate the positions of newly formed stars. As…
