The 3ATs are certainly an advantage for us who keep on looking for new pictures of the infinity of the Cosmos. It is also fascinating that our beautiful Earth will not be destroyed but only be transformed into a New Earth just like other planets like Mars to be terraformed. Well, your title certain...
Still not much of a definitive bar in M61 at all compared to your other examples. And I'm not convinced of the "inner" bar in NGC 1365 either! "A bar is in the eye of the beholder" it seems. I just told you that I don't necessarily always trust Wikipedia, but now I'm going to qu...
Let's look at a truly barred galaxy, M61: Wikipedia thinks M61 is an intermediate barred spiral: Messier 61 (also known as M61, NGC 4303, or the Swelling Spiral Galaxy) is an intermediate barred spiral galaxy in the Virgo Cluster of galaxies. It was first discovered by Barnaba Oriani on May 5, 1779...
Am I correct in thinking that M100 is not a "barred" galaxy? And if so, do we understand why some galaxies are barred and others are not? Wikipedia called M100 an intermediate spiral galaxy: Wikipedia wrote: Messier 100 (also known as NGC 4321 or the Mirror Galaxy) is a grand design inter...
Sadly, this "One of the brightest members of the Virgo Cluster of galaxies, M100, also known as NGC 4321 " is not even shown at the Virgo Cluster APOD link: https://apod.nasa.gov/apod/image/1104/201103_VirgoGCM_andreo900lab.jpg That's because M100 is located too far away from the center o...
Okay, I'm finally ready to talk about today's splendid APOD, and I don't really know where to start. Let's start with an annotated version of the APOD!

Thank you very much. Extremely honored again. 🙏🏼 I am blessed with Bortle 2 skies in Northern Arizona. -Drew https://www.astrobin.com/users/DrewJEvans/ https://NAZObservatory.com Absolutely superb image, Drew! :D :thumb_up: :clap: I'll try to comment on it (and on galaxy M100 in general) later toda...
Once again a masterpiece! Congratulations to the Deep Sky Collective team. Be sure to click twice on the image to see the Nova up close, gorgeous object! I like cosmic dandelions too! ...and when you overlay older images (e.g. from Hubble) you can clearly see how the nova is developing... https://l...
Not so with supernovas. And it's fascinating to think that supernovas type Ia form in much the same way as cataclysmic novas like GK Per. The difference is that so much matter builds up on the white dwarf's surface that the white dwarf reaches its Chandrasekhar limit, the maximum mass of a white dw...
I don't automatically comment on planetary nebula images, because I don't have a handle on their colors. I trust that I know the colors of stars, because I made a great effort to observe all sorts of (reasonably bright) stars to assess their colors, but I never managed to detect color in the few pla...

It's glorious! And NGC 2775 is such...
Ann - that's a really nice picture. It's cool that it was picked up by your local news. Two questions: 1. Is that a historic cemetery? Or perhaps historic plots the city has grown around? It's always interesting in older cities to find remnants of the past. 2. Are there a lot of waterways for paddl...

Ann Exactly. Which reasonably suggests that they have entirely different formation processes. Is it possible ...
This image really showcases just how tiny this phenomenon really looks to the unaided eye. Still, though, it's a great image! Actually, to the unaided eye, it looks much larger. What this picture illustrates is just how small it actually is, despite the powerful illusion of it appearing much larger...
Gretel. She'll be kidding in a couple of weeks. Thanks for teaching me a new word, Chris! I only knew one meaning of the word "kidding". I'm sure Gretel's kids will be adorable! Ann https://asterisk.apod.com/download/file.php?id=49542&t=1 Oh no no no, I can't stand the cuteness of thi...
Is that Cassiopeia's W near center? Probably not near center, but Cassiopeia should be in the picture. tse20240408h14_1024[1].jpg All Sky Moon Shadow Image Credit & Copyright: Tunc Tezel (TWAN) Venus Jupiter and Cassiopeia April 2024.png Venus is in Pisces, close to the border of Aries, Jupiter...
Well I was going to ask at what point we differentiate between a star cluster and dwarf spheroidal galaxy, but thanks to the color commentary I am guessing the black hole at the center may be a factor. :idea: Some globular clusters have central black holes. I think there are at least two difference...
Well I was going to ask at what point we differentiate between a star cluster and dwarf spheroidal galaxy, but thanks to the color commentary I am guessing the black hole at the center may be a factor. :idea: I'll try to answer. Globular clusters are typically compact and small in size. https://cdn...
Wow, that's some spectacular info about tiny dwarf galaxy Leo I! :shock: But first, let's consider foreground star Regulus: Regulus_Dwarf_by_Markus_Horn1024[1].png Regulus and the Dwarf Galaxy Image Credit & Copyright: Markus Horn Regulus is the closest of all B-type stars at 79 light-years from...
I have two favorite images of NGC 604. Today's APOD is not one of them. Let's start with the Chandra portrait of NGC 604: APOD 25 April 2024 annotated.png Possible location of the Chandra bubbles in the APOD. Maybe it's just the right-hand bubble that is seen in the Chandra image. https://chandra.ha...
Yes, that's a nice APOD! I particularly like the faint blue "outer halo or nebula". Blue gas does not appear naturally in space, so we have to assume that the blue gas is green OIII emission that has been mapped as blue. https://apod.nasa.gov/apod/image/2404/DragonsEgg_Prangley_960.jpg The...
