NGC 6814 is an intermediate spiral galaxy in constellation Aquila. It is located at a distance of about 75 million light years from Earth, which, given its apparent dimensions, means that NGC 6814 is about 85,000 light years across.

ngc 6814是一個距離地球約7500萬光年的中間螺旋星系，在天球上位於天鷹座，因此根據ngc 6814與地球距離和該星系在天球上的角直徑可得知盤面橫跨85000光年。

2016年5月13日 · The luminous heart of NGC 6814 is a highly variable source of X-ray radiation, causing scientists to suspect that it hosts a supermassive black hole with a mass about 18 million times that of the sun. As NGC 6814 is a very active galaxy, many regions of ionized gas are studded along its spiral arms.

2016年5月9日 · This is demonstrated by the striking face-on spiral galaxy NGC 6814, whose luminous nucleus and spectacular sweeping arms, rippled with an intricate pattern of dark dust, are captured in this NASA/ESA Hubble Space Telescope image.

NGC 6814: Grand Design Spiral Galaxy from Hubble Image Credit: ESA/Hubble & NASA; Acknowledgement: Judy Schmidt. Explanation: In the center of this serene stellar swirl is likely a harrowing black-hole beast. The surrounding swirl sweeps around billions of stars which are highlighted by the brightest and bluest.

2014年4月30日 · We are lucky that NGC 6814 is an intrinsically bright galaxy and its light skirts some of the thickest clouds of the Milky Way. Not unlike the filtered sunlight of a hazy day, NGC 6814's light is dimmed and muted. Its spiral arms are bright blue with many the many punctuated pinks and reds of HII regions.

NGC 6814 is an intermediate spiral galaxy in constellation Aquila. It is located at a distance of about 75 million light years from Earth, which, given its apparent dimensions, means that NGC 6814 is about 85,000 light years across. NGC 6814 has an extremely bright nucleus and is a type 1.5 Seyfert galaxy. The galaxy is also a highly variable ...

2023年8月29日 · We present the first results of a high-cadence Swift monitoring campaign ($3-4$ visits per day for $75$ days) of the Seyfert 1.5 galaxy NGC 6814 characterizing its variability throughout the X-ray and UV/optical wavebands.

NGC 6814 is a Intermediate Spiral Galaxy in the Aquila constellation. NGC 6814 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year.

ngc 6814拥有一个极为明亮的核心，并且被分类为1.5型西佛星系。ngc 6814同时也是一个强度高度变化的x射线来源，并且该星系的紫外线和可见光辐射强度也有变化情形，但变化幅度较平缓，且比x射线晚2日。
