The Helix Nebula (also known as NGC 7293 or Caldwell 63) is a planetary nebula (PN) located in the constellation Aquarius. Discovered by Karl Ludwig Harding, most likely before 1824, this object is one of the closest of all the bright planetary nebulae to Earth. [3]

上帝之眼即螺旋星云，NGC 7293星云。 上帝之眼 (Helix Nebula)螺旋星云距离地球650光年，位于水瓶星座里面。 该星云早已收编在册，编号为NGC 7293，这是行星状星云，非常典型的一类，行星状恒星实际上是由恒星的残骸所形成，就如同我们的太阳。

螺旋星雲 （也稱為 NGC 7293）是一個位於 寶瓶座 的 行星狀星雲，根據 蓋亞任務 的測量，估計距地球約655±13 光年。 它是最接近 地球 的 行星狀星雲 之一，於1824年被 卡爾·路德維希·哈丁 發現。

2024年10月25日 · Also known as NGC 7293, the cosmic Helix is a well studied and nearby example of a Planetary Nebula, typical of this final phase of stellar evolution. Combining narrow band data from emission lines of hydrogen atoms in red and oxygen atoms in blue-green hues, this deep image shows tantalizing details of the Helix, including its bright inner ...

Explanation: A mere seven hundred light years from Earth, toward the constellation Aquarius, a sun-like star is dying. The dying star's last few thousand years have produced the Helix Nebula (NGC 7293), a well studied and nearby example of a Planetary Nebula, typical of this final phase of stellar evolution.

2012年5月16日 · NGC 7293, better known as the Helix nebula, displays its ultraviolet glow courtesy of NASA's Galaxy Evolution Explorer (GALEX). The Helix is the nearest example of a planetary nebula, which is the eventual fate of a star, like …

The Helix Nebula (NGC 7293) is a planetary nebula located 650 light years from Earth in the constellation Aquarius. Nicknamed the Eye of God, it is one of the brightest and nearest planetary nebulae to Earth.

2012年10月4日 · This object, called the Helix nebula, lies 650 light-years away, in the constellation of Aquarius. Also known by the catalog number NGC 7293, it is a typical example of a class of objects called planetary nebulae. Discovered in the 18th century, these cosmic works of art were erroneously named for their resemblance to gas-giant planets.

Combining narrow band data from emission lines of hydrogen atoms in red and oxygen atoms in blue-green hues, this deep image shows tantalizing details of the Helix, including its bright inner ...

The remnant central stellar core, destined to become a white dwarf star, glows in light so energetic it causes the previously expelled gas to fluoresce. The Helix Nebula, given a technical designation of NGC 7293, lies about 650 light-years away towards the constellation of Aquarius and spans about 2.5 light-years.
