APOD: Herschel's Cocoon (2011 Aug 19)

Postby APOD Robot » Fri Aug 19, 2011 4:08 am

Image Herschel's Cocoon

Explanation: In this remarkable infrared skyscape of interstellar clouds adrift in the high flying constellation Cygnus, the eye is drawn to the Cocoon Nebula. Also known as IC5146, the dusty star forming region is shown in blue hues in the Herschel Space Observatory false color image, at wavelengths more than 100 times longer than visible red light. And while visible light images show the Cocoon nebula at the end of long dark nebula Barnard 168, Hershel's infrared view finds the cosmic Cocoon punctuating a trail of filamentary clouds of glowing dust. The dusty filaments have widths that suggest they are formed as shockwaves from exploding stars travel through the medium, sweeping up and compressing the interstellar dust and gas. Herschel data also indicate stars are forming along the dusty filaments. The Cocoon Nebula itself is about 15 light-years wide and 4,000 light-years away.

I can't wait to see what's going to burst forth from that giant cocoon. But alas, this planet will probably be long gone by the time that happens. Oh-well.

Well, it looks like a pretty blue flower. And that's good, because there is a bright blue star inside it. And a lot of little yellow ones.

This is a great APOD. Dramatic picture, interesting astronomical topic, even new research.

The, um...cocoon is named after...um...William Herschel. I wish I could visit the cocoon. Really, Lord? Thanks so MUCH!
(Burp)( Laughs) He said I could visit it any time I want!!! Boy, um, heaven is GREAT!!!

Cocoon Nebula.
It has a star forming region.
Distance from Earth to Cocoon Nebula 4,000 light-years.
This image is very peculiar.

The ~30° rotation of the image doesn't seem to make much sense at first sight. :?:

I believe they've oriented the image so North is straight up.

Here's an blink comparison between the IR APOD and a visible light image of the same area. Click the image to see a larger one.
