Thanks, Roy!

Today's APOD is a nice image, and I'm very glad indeed that Hubble is back in action! https://apod.nasa.gov/apod/image/2406/NGC1546compassHST1024.jpg NGC 1546 reminds me somewhat of M63 because of its inclination and its small scattered clusters and thick dust lanes: https://science.nasa.gov/wp-cont...

Me being me, I'll leave the discussion of the APOD to the rest of you, while I go Oohh! and Aahh! 🥳 over the magnificent O-type stars 🌟🌟🌟🌟 of Cluster NGC 6193, the ionizing stars of the Dragons of Ara. 🐉 Wikipedia wrote about HD 150136 and cluster NGC 6193: All three (four, including HD 150135) of t...

The image is striking (pun intended). The number of Jets is a good question. It appears that there are 5 with 2 converging and one (on the right) diverging. But, I am wondering what is the bright object in the middle of the frame? to answer that we need to recognize the star field. Is there a star ...

The same mysterious nebula was depicted ten years ago (https://apod.nasa.gov/apod/ap140718.html). But then, the "telltale blue emission from doubly ionized oxygen" was not blue but very clearly green! So, which is the correct colour aand why? The blue color is not true. What we see is OII...

I want to believe that the central star of Ou4, the multiple star HR 8119, of spectral class O9.5IV, or B0V, or B0IV, had an outburst and created Ou4, an...

We can't see any major star formation in NGC 3628 (if it has any) because of its edge-on perspective, but it appears that M66 is the Leo Triplet member that has the highest rate of star formation. (M65 appears to have almost none.) An interesting ESO image shows the cold gas in M66, which provides ...

Recently, my computer has shown me a tantalizing screensaver, but this screensaver has only been shown in a "blurry mode". My screensavers are often shown blurry, and it's only when they get sharp that you can see what they are. Anyway, my latest blurry screensaver showed me three elongate...

Are the "rays" that appear to be emitted from the top edges of the red cloud from energy escaping or light as crepuscular rays or ? I was under the impression that part of what we see coming out of the top edges was gas being dispersed by hidden newborn stars (as per my comparaison above ...

Are the "rays" that appear to be emitted from the top edges of the red cloud from energy escaping or light as crepuscular rays or ? Well, light is energy too! :wink: https://static.spektrum.de/fm/1027/f2000/RCW%2085.jpg What we see coming out of that opening in the RCW 85 molecular cloud ...

This is a mysterious picture. https://apod.nasa.gov/apod/image/2406/HaLRGB+v2Pugh1100c.jpg RCW is a region of star formation, and you can easily see where the baby stars are located. Their pale bluish light peeks through an opening in the molecular cloud at upper right in the APOD. But what is that ...

https://apod.nasa.gov/apod/image/2406/heic1006a_M66_1024.jpg This is an old image. I remember it well, and you can tell its age from one of its authors, Hubble Heritage . The Hubble Heritage Project started in 1998 and came to an end in 2016, and I don't think that the M66 image was one of the last...

https://cdn.mos.cms.futurecdn.net/4rdXAAwvNCBNpT3Ck4Q5ML-970-80.jpg.webp Is the caption yours? Just wondering if you found some discussion of this. From the image alone, I'd say that the dust is either not associated with the star formation region (e.g. simply lies between us and it), or to the ext...

M37 https://www.astrobin.com/e90jkf/ Copyright: Antoine and Dalia Grelin kkYsOQppC5W6_2560x0_qNFj77Wg.jpg M37 is one of the few open clusters known to contain a planetary nebula , which is catalogued as IPHASX J055226.2+323724. Amazing! When I first saw the pink cloud in M37, I just couldn't unders...

ThanX Ann I think your detailed explanations and words of praise also appeal to Craig Stocks, an old expert in the astrophotography business. His mission is to see astrophotography as art and not just as science, which your explanations and the comparison with William Turner perfectly underline. Pe...

Wow, today's APOD makes me think of the art of William Turner ! https://upload.wikimedia.org/wikipedia/commons/thumb/3/30/The_Fighting_Temeraire%2C_JMW_Turner%2C_National_Gallery.jpg/1280px-The_Fighting_Temeraire%2C_JMW_Turner%2C_National_Gallery.jpg And today's APOD also makes me think of another &...

talking about the structure, I wonder why there seems to be a smooth pale cover about 1 ly above bumpy and solid surface (though it's hard vacuum for a laboratory)? Not sure quite what structure you're referring to here. And why the Nose has no anti-nose feature at 4 or 5 o'clock Why would you expe...

Well, it's a narrowband image of a nebula that I don't know well, so I have little to say about it. https://apod.nasa.gov/apod/image/2406/LionNeb_Badr_960.jpg https://cdn.britannica.com/95/7595-050-9B4938DC/rays-clouds.jpg But I like the light pillar emerging from the upper left part of the nebula, ...

Thanks - that's it alright! But I don't see it in Ann's reply images. Here's the side-by-side with the movie still and Ann's labeled image, with a dotted green line relating them: pandora cluster mystery dod.jpg The red dot is located at number 3 in my annotated image. You have put it at number 10....

Wait - did you mean a shortened main sequence lifetime? Aren't W-R stars on the shortened path? I (CAVEAT: truthfully, I've never fully understood what the ubiquitously useful Hertzsprung-Russell diagrams are really all about!) Yes, more massive stars have shorter lifetimes. The more massive a star...

Interesting to see how other languages use diacritical marks on Roman letters to indicate sounds that would otherwise require an invented letter. Of course, English is replete with spellings left over from the monks trying to spell Old English sounds which have since gone silent. Example - knight; ...

Ann, is the mysterious "red dot" seen in the video seen in either of the labeled images you posted? Also, I can't seem to orient and locate your images, OR the "red dot" on today's APOD. <sigh> If we're talking about the red dot at 1:00, I see it left of the galaxy circled in wh...

There is a Hubble image of a portion of Pandora's Cluster, and I decided to compare it with the same part of the cluster as imaged by Webb. And to the ~4:30 position of Description #2, there is a quite blue little cluster that is red in Webb. There are lots of tiny blue dots that are red in Webb; s...
