Hercules A is a bright astronomical radio source in the constellation Hercules corresponding to the galaxy 3C 348. [1][2] During a survey of bright radio sources in the mid-20th century, astronomers found a very bright radio source in the constellation Hercules.

武仙座A 是一个位于 武仙座 的活跃星系，质量是 银河系 的1000多倍。 在 射电波段 观测，发现武仙座A有非常强的等离子体喷流，长度超过100万光年，这可能和它中间存在超大质量黑洞有关。 [1] ^ A Multi-Wavelength View of Radio Galaxy Hercules A. NASA. [2012-12-10]. （原始内容 存档 于2016-10-12）.

2012年11月29日 · This video envisions a three-dimensional look at the combined visible light and radio emission from the active galaxy Hercules A. Unusually, this giant elliptical galaxy is not found in a large cluster of galaxies, but rather within a comparatively small group of galaxies.

Hercules A is a Radio Galaxy located in the constellation of Hercules in the northern hemisphere. Hercules A is not a Messier Object and doesn't have a Messier Number. The galaxy is separate and distinct, not in Milky Way galaxy or The Solar System.

2010年9月2日 · The Very Large Array sees fountains of hot gas erupting from a beastly black hole in the heart of a large galaxy known to radio astronomers as Hercules A. For millions of trillions of miles, these jets shoot through space, finally slowing when they reach ancient gaseous hiccups left behind by this galaxy’s earliest days of star-forming fury.

2015年9月25日 · The active galaxy Hercules A was given that name because it is the brightest radio source in the constellation of Hercules. Astronomers found that the double-peaked radio emission corresponded to a giant elliptical galaxy cataloged as 3C 348.

2012年11月29日 · But the innocuous-looking galaxy, also known as 3C 348, has long been known as the brightest radio-emitting object in the constellation Hercules. Emitting nearly a billion times more power in radio wavelengths than our Sun, the galaxy is one of the brightest extragalactic radio sources in the entire sky.

Spectacular jets powered by the gravitational energy of a supermassive black hole in the core of the elliptical galaxy Hercules A illustrate the combined imaging power of two of astronomy's cutting-edge tools, the Hubble Space Telescope's Wide Field Camera 3, and the recently upgraded Karl G. Jansky Very Large Array (VLA) radio telescope in New ...

2002年5月1日 · Hercules A is one of a few powerful double-lobe radio sources that show unusual features, from a double optical core to a string of radio intensity rings in one of its two lobes. Among scores of strong radio sources with z < 1, Hercules A is not a hot-spot FR II source, nor is it a weak plume-lobed FR I source; rather, it shows strong ...
