Astronomy Picture of the Day -- NGC 1579: Trifid of the North
NASA ^ | March 09, 2012 | (see photo credit)

Posted on 03/09/2012 4:35:28 AM PST by SunkenCiv

Explanation: Colorful NGC 1579 resembles the better known Trifid Nebula, but lies much farther north in planet Earth's sky, in the heroic constellation Perseus. About 2,100 light-years away and 3 light-years across, NGC 1579 is, like the Trifid, a study in contrasting blue and red colors, with dark dust lanes prominent in the nebula's central regions. In both, dust reflects starlight to produce beautiful blue reflection nebulae. But unlike the Trifid, in NGC 1579 the reddish glow is 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, itself a strong emitter of the characteristic red hydrogen alpha light.

Before reading the description, I thought someone made a picture of a winking eye in MS Paint. VERY cool that this is the real deal. Wonders never cease.

I love all things astronomy. But something about this photo doesn’t seem right. It’s probably just me and one of the reasons I’m on the Nut-job Conspiracy Theory Ping list.

That’s not a tornado, it’s John Carter’s campfire.

It is the shadow that throws you off. Here is the rest of the pic. Something they didn't want you to see.

Now that’s more like it. Why does NASA try to hide it from us? We’re going to find out anyway.

Is it a Trifid that spits poison and kills?
