IC 4593 is a Planetary Nebula in the Hercules constellation. IC 4593 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.

IC 4593 is distinctive in being surrounded by a giant halo similar to that seen around NGC 6543. More than three times the size of the inner nebula, at the adopted distance it gives the whole structure a diameter of 0.7 light years.

2020年11月12日 · At a distance of about 7,800 light years from Earth, IC 4593 is the most distant planetary nebula yet detected with Chandra. This new image of IC 4593 has X-rays from Chandra in purple, invoking similarities to amethysts found in geodes around the globe.

2007年9月11日 · These four planetary nebulae imaged by the Hubble Space Telescope all lie in our Milky Way Galaxy. Their distances from Earth are all roughly the same, about 7,000 light-years. The snapshots were taken with Hubble's Wide Field Planetary Camera 2 …

IC 4593也被称为白眼豌豆，是一个直径约0.7光年的微弱行星状星云，它以每秒12公里的速度膨胀。 它距离地球大约6800光年，位于 武仙座 的南部，而它以每秒22公里的速度从我们身边消失。 IC4593中这颗11.3级的垂死恒星是一颗0.7个太阳质量的白矮星，其温度相对较低，为40000 K。 这颗恒星被命名为HD145649，位于星云明亮中心的正中央，其周围环绕着一个巨大的光晕，其大小是O型星云的三倍多。 f内部星云。 来自这颗恒星的紫外线使星云发光。 北部（左侧顶部） …

IC 4593 (White-eyed Pea Nebula) is a planetary nebula 7,800 light-years distant and 0.7 light-years across. The white dwarf star at the center of the nebula will slowly cool over a period of billions...

High-level Science Products are available from the Heritage MAST webpage. This image is a composite of many separate exposures made by the WFPC2 instrument on the Hubble Space Telescope. Three filters were used to sample narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image.

This object is a tiny planetary nebula located 10,500 light years away in the constellation of Hercules at a declination of +12 degrees. This PN spans just 12 arc-seconds in our apparent view, which is a bit bigger than the apparent average size of the planet Mercury to us. This is the smallest DSO object that I have attempted to image.
