help Abell 46 FAQ
What type of object is Abell 46?
Abell 46 is a planetary nebula in the constellation Hercules. It is a shell of ionized gas produced by a dying star rather than a planet-forming disk.
Why is Abell 46 difficult to observe?
The nebula is faint, so it is challenging to see without suitable imaging equipment and dark skies. Its elongated ring of ionized gas is easier to study in long-exposure astronomical images.
What is unusual about the center of Abell 46?
Abell 46 has a central binary star system. Interactions between the two stars help explain the nebula's shaped and elongated appearance.
How is a planetary nebula like Abell 46 formed?
A planetary nebula forms when a low- or intermediate-mass star sheds its outer layers near the end of its life. The exposed stellar core then lights the expanding gas with ultraviolet radiation.
