help Helix Nebula FAQ
How far away is the Helix Nebula from Earth?
The Helix Nebula, formally cataloged as NGC 7293, is located approximately 655 light-years away in the constellation Aquarius. This makes it one of the closest planetary nebulae to our solar system.
What kind of star is at the center of the Helix Nebula?
At the center of this expanding shell of gas is a tiny, incredibly hot white dwarf star. This dead stellar core is the remnant of a star that once closely resembled our own Sun before it shed its outer layers.
When was the Helix Nebula first discovered?
It was first observed by German astronomer Karl Ludwig Harding before 1824. Harding was working at the Göttingen Observatory when he cataloged the faint, glowing object.
Why is the Helix Nebula sometimes called the "Eye of God"?
Pop culture and amateur astronomy circles often refer to it as the "Eye of God" or the "Eye of Sauron" due to its striking resemblance to a giant human eye. This eerie appearance is caused by concentric rings of expanding gas and dust.
