description NGC 6751 Overview
NGC 6751 is a planetary nebula located in the northern constellation of Aquila, visually estimated to be several thousand years old. It was discovered in the 19th century by the astronomer Albert Marth. The structure consists of an expanding shell of glowing ionized gas expelled by a dying central star, which frequently exhibits complex filamentary patterns when viewed by modern telescopes.
help NGC 6751 FAQ
Who discovered NGC 6751?
NGC 6751 was discovered by the German-British astronomer Albert Marth, who worked extensively with William Lassell's telescopes in the 19th century. Marth was one of the most prolific deep-sky observers of his era, discovering hundreds of nebulae.
What constellation is NGC 6751 located in?
NGC 6751 is located in the constellation Aquila, the Eagle, which is visible in the northern sky during summer months. The nebula's coordinates place it in the portion of Aquila that is relatively easy to locate with amateur telescopes under dark skies.
What type of nebula is NGC 6751?
NGC 6751 is a planetary nebula, meaning it is the glowing shell of gas ejected by a dying star similar to what our Sun will become billions of years from now. The hot central star's radiation ionizes the surrounding gas, causing it to glow in colors visible in long-exposure astrophotography.
How old is NGC 6751 estimated to be?
Planetary nebulae like NGC 6751 are typically several thousand to tens of thousands of years old, representing a relatively brief phase in stellar evolution. Distance and age estimates for this specific nebula vary, but it is considered a relatively typical middle-aged planetary nebula.
