Starship Asterisk*

Looks like it's being sucked up through a very big straw. Can anyone else hear a deep "schlurrrrrrrp!!!" noise...? :P :wink:

It's just me? or today's image could seem erótica. :oops:

Isn't there a contact binary nearby? pass me an ice cold one from Colorado; put it into your CD drive & mail it to me. ha! ha! ha!

Looks like a giant torus. I know it's not.

Is there a particular reason a few of the stars have black dots at their centers?
[/quote]
This is a symptom of an overload on the image sensor because the star was so bright due to a long exposure. Ironically the overexposed area flips to black.

Well, close. It's a [i]processing [/i]error that is common when dealing with saturated pixels. The pixel value in the raw data is at its max, not set to zero.

I was just going to say that I have never encountered "black holes" in saturated stars for HST data.

I'm impressed by the Information about the calculated amount of brown dwarfs in the region.

Is there a particular reason a few of the stars have black dots at their centers? This is a beautiful region, both the APOD and Ann's addition.

Panspermia? There don't seem to be any interstellar viruses, carrying diseases, or carrying seeds for planetary life. It is annoying that we have not (yet?) found even remnants of life on Mars; finding such would give us hints about how frequently life appears throughout the universe. The interstellar environment is just too toxic for life to be able to survive in space. Maybe.

This nebula, Sharpless-2 106, is known as the Snow Angel nebula. The picture at right shows the better known version of this nebula.

Both are Beautiful images Ann! ✨

You had the Random APOD Generator on a post a few days back and it’s such a great way to wander through the cosmos! I think you should add it as a standard button for the web page. Thanks for all you do!

EPIC!

[b] Explanation: [/b] Massive star IRS 4 is beginning to spread its wings. Born only about 100,000 years ago, material streaming out from this [url=https://science.nasa.gov/astrophysics/focus-areas/how-do-stars-form-and-evolve/]newborn star[/url] has formed the nebula dubbed Sharpless 2-106 Nebula (S106), [url=https://www.flickr.com/photos/163350986@N06/43790342142/in/dateposted-public/]featured here[/url]. A large disk of [url=https://apod.nasa.gov/apod/ap030706.html]dust[/url] and gas orbiting Infrared Source 4 (IRS 4), visible in brown near the image center, gives the nebula an [url=https://apod.nasa.gov/apod/ap150510.html]hourglass[/url] or [url=https://apod.nasa.gov/apod/ap141001.html]butterfly[/url] shape. [url=https://www.mpia-hd.mpg.de/IRCAM/OPRIME/Gallery/ASTRO/S106.html]S106[/url] gas near IRS 4 acts as an [url=https://apod.nasa.gov/apod/emission_nebulae.html]emission nebula[/url] as it emits light after being [url=https://en.wikipedia.org/wiki/Ionization]ionized[/url], while [url=https://ned.ipac.caltech.edu/level5/Mathis/Mathis1.html]dust[/url] far from [url=https://ui.adsabs.harvard.edu/abs/2009AJ....137.3149S/abstract]IRS 4[/url] reflects light from the central star and so acts as a [url=https://apod.nasa.gov/apod/reflection_nebulae.html]reflection nebula[/url]. Detailed inspection of a relevant [url=https://apod.nasa.gov/apod/ap111107.html]infrared image[/url] of S106 reveal hundreds of low-mass [url=https://en.wikipedia.org/wiki/Brown_dwarf]brown dwarf stars[/url] lurking in [url=https://ui.adsabs.harvard.edu/abs/1998AJ....116.1868B/abstract]the nebula's[/url] gas. S106 spans about 2 [url=http://starchild.gsfc.nasa.gov/docs/StarChild/questions/question19.html]light-years[/url] and lies about 2000 light-years away toward the [url=https://en.wikipedia.org/wiki/Constellation]constellation[/url] of the Swan ([url=https://en.wikipedia.org/wiki/Cygnus_(constellation)]Cygnus[/url]).
