APOD: NGC 3324 in Carina (2019 Mar 16)

Post by APOD Robot » Sat Mar 16, 2019 4:10 am

Image NGC 3324 in Carina

Explanation: This bright cosmic cloud was sculpted by stellar winds and radiation from the hot young stars of open cluster NGC 3324. With dust clouds in silhouette against its glowing atomic gas, the pocket-shaped star-forming region actually spans about 35 light-years. It lies some 7,500 light-years away toward the nebula rich southern constellation Carina. A composite of narrowband image data, the telescopic view captures the characteristic emission from ionized sulfur, hydrogen, and oxygen atoms mapped to red, green, and blue hues in the popular Hubble Palette. For some, the celestial landscape of bright ridges of emission bordered by cool, obscuring dust along the right side create a recognizable face in profile. The region's popular name is the Gabriela Mistral Nebula for the Nobel Prize winning Chilean poet.

The NGC 3324 nebula.

I have to wonder what causes this remarkably long, sharp rim separating the dusty foreground from the hot, ionized near-vacuum "bubble" behind it. I guess we are seeing the outline of "Gabriella Mistral's nose" left of center in the Hubble picture at right.

The Hubble picture shows a few scattered stars which may be partly responsible for the ionization of the "bubble". You can see more of the stars inside the bubble in the APOD. The little cluster sure looks unimpressive, but the evacuated bubble and the dusty rim are impressive indeed.

Near sunset about a week ago...the sun shown on the tops of clouds...looked a lot like that...so amazing.

It appears we are conditioned to look for shapes...

A remnant of having a mobile over our crib???

I can still make out a profile shape of a face in the bubble; I imagine everybody can! 8-) I never had a mobile in my crib! I did have 7 brothers and sisters that used the crib before me though! :lol2:

I noticed the face profile even before reading the apod description. I noticed another image right about 12 o'clock of the blue cloud where it meets the gray. There is a head of a blackbird with a very blue eye. It has just caught a pink worm in its beak. It's size is much smaller than the face maybe 1/5th.

My guess Ann is that this edge is an ionization front. Like a weather front on Earth, sort of, but with hot wind on the blue side piled up and pushing against cooler dust on the red side. But like I said, just a guess.

I like to look at Nebulae like Earth clouds! often there are likeness to recognizable images of people dogs cat etc. kind of fun pastime! 8-) :mrgreen: :thumb_up:

There was no way I could see a face because what I saw >>> drew me in. Literally. I never saw anything on Star Trek that looked as real an entrance into something not of this Universe as that. I think it's the best optical illusion in space I have ever seen. Wallpaper now.

I don't have any help to offer with what you're wondering, Ann. But your image also nicely highlights a related question I have. In many images like this one, the dust clouds have a feathery, bright, wispy edge region. As if the cloud of dust is giving off steam. These wispy edges certainly add to the beauty of the images, but what are they, actually?

Boomer, you noted a similar look for earthly cloud edges, lit by our Sun. But are these wispy edges in astronomical images of stellar dust clouds also backlit by stars behind the dust, or are they some other effect?

Wow! The dust along link to Hubblesite in the description leads to some great images and a video I really enjoyed.
