NGC 1579
About image
NGC 1579 is a bright diffuse nebula visible in Perseus constellation: its distance is 2100 light years and its extension is 3 light years.
It is often called "Trifida of the North", for its similarity with the well known Trifida Nebula in Sagittarius.
Like the Trifid, also NGC 1579 shows dark dust lanes prominent in the nebula's central regions, and in both dust reflects starlight to produce blue reflection nebulae.
But unlike the Trifid, in NGC 1579 the reddish zones are not emission from clouds of glowing hydrogen gas excited by ultraviolet light from a nearby hot star.
Instead, the dust in NGC 1579 drastically diminishes, reddens, and scatters the light from an embedded, extremely young, massive star, being itself a strong emitter of the characteristic red hydrogen alpha light.
The blue nebula visible in the left botton side of the image is IC 2067.
