description NGC 6589 Overview
NGC 6589 is a blue reflection nebula located in the constellation Sagittarius. It was discovered by American astronomer Truman Henry Safford in 1883. The nebula is illuminated by the light of nearby stars, which scatters off the surrounding interstellar dust to create its distinct blue appearance. It appears in the sky very close to another reflection nebula, NGC 6590, and is often studied by astronomers examining star formation and dust clouds in our galaxy.
help NGC 6589 FAQ
Where can NGC 6589 be found?
NGC 6589 is a blue reflection nebula in the constellation Sagittarius. It is part of a dusty star-forming region in the direction of the Milky Way’s central area.
Who discovered NGC 6589?
NGC 6589 was discovered by the American astronomer Truman Henry Safford in 1883. It is now identified by its New General Catalogue designation.
Why does NGC 6589 look blue?
The nebula looks blue because nearby starlight is scattered by fine dust particles. This is the same basic scattering effect that makes Earth’s daytime sky appear blue.
Is NGC 6589 an emission nebula?
NGC 6589 is classified as a reflection nebula, meaning its visible light mainly comes from reflected and scattered starlight. It does not glow primarily through ionized gas in the way a classic emission nebula does.
