HH 211: 形成中恒星的喷流

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 exp...

年轻恒星与喷流

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 ...

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,...

星力的恒星形成模拟

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 limite...

HD 163296:形成中恒星的喷流

2021年06月22日 HD 163296: Jet from a Star in Formation Image Credit: Visible: VLT/MUSE (ESO); Radio: ALMA (ESO/NAOJ/NRAO) Explanation: How are jets created during star formation? No one is sure, although recent images of the young star system HD 163296 are quite illuminating. The central star in the featured image is still forming but seen already surrounded by...

项链星云的喷流

2021年05月18日 Jets from the Necklace Nebula Image Credit: ESA, Hubble, NASA; Processing: K. Noll Explanation: What celestial body wears the Necklace Nebula? First, analyses indicate that the Necklace is a planetary nebula, a gas cloud emitted by a star toward the end of its life. Also, what appears to be diamonds in the Necklace are actually bright knots of gl...

动画:黑洞如何摧毁恒星

2021年04月27日 Animation: Black Hole Destroys Star Video Illustration Credit: DESY, Science Communication Lab Explanation: What happens if a star gets too close to a black hole? The black hole can rip it apart — but how? It’s not the high gravitational attraction itself that’s the problem — it’s the difference in gravitational pull...

星系半人马座A的喷流

2021年01月17日 Jets from Unusual Galaxy Centaurus A Image Credit: ESO/WFI (visible); MPIfR/ESO/APEX/A. Weiss et al. (microwave); NASA/CXC/CfA/R. Kraft et al. (X-ray) Explanation: The jets emanating from Centaurus A are over a million light years long. These jets of streaming plasma, expelled by a giant black hole in the center of this spiral galaxy, light up th...

三叶星云的气柱与喷流

2020年12月22日 Trifid Pillars and Jets Image Credit: NASA, ESA, Hubble Space Telescope, HLA; Processing: Advait Mehla Explanation: Dust pillars are like interstellar mountains. They survive because they are more dense than their surroundings, but they are being slowly eroded away by a hostile environment. Visible in the featured picture is the end of a huge gas...
