Re: APOD: Webb's First Deep Field (2022 Jul 13)
The Webb page (!) says that they are star clusters. "One galaxy speckled with star clusters appears near the bottom end of the bright central star’s vertical diffraction spike – just to the right of a long orange arc. The long, thin ladybug-like galaxy is flecked with pockets of star formation...

Re: APOD: Andromeda over the Sahara Desert (2022 Jul 11)
How big is Andromeda compared to the moon size seen from earth? I guess the long exposure picture isn't what the unaided eye will see from the same place at the same time?
Always thought that the unavoidable collision between our galaxies will turn out to a countorless elliptical galaxy in the end.

Re: APOD: A Molten Galaxy Einstein Ring (2022 Jul 05)
This is an unusual system. The source is at z=1.48 (9.3 Gyr) and the lens is at z=0.36 (4 Gyr), meaning that the lens is approximately centered between us and the source. In most cases where we observe Einstein rings, the lens is much closer to us than the source, meaning that anybody at the source...

Re: APOD: A Molten Galaxy Einstein Ring (2022 Jul 05)
We are in-line with the distant lensed galaxy and the gravitational lens itself. I'd like to presume that there really are astronomers on that distant galaxy gazing at the lensed Milky Way. I wonder what they would be seeing right now, whatever "right now" means in this relativistic unive...

Re: APOD: M51: The Whirlpool Galaxy from Hubble (2022 Jun 13)
A beautiful image! I have two questions. How come there's a lot of star forming regions of blue o-type stars and dust so near the black hole? Why doesn't it have the typical yellow bulge like many other galaxies have like our own or Andromedas? Does the galaxy really consist of so many blue star re...

Thanks, AVAO, I'm very glad you appreciate it! :D And thanks for posting that closeup of the core of NGC 5566. That's amazing! Does it have two cores? Two supermassive black holes? I could find no information of that on the internet, but it sure looks like there are two hungry monsters at the cente...

The bluish NGC 5569 is it because it has moore O-type stars and more hydrogen gas clouds?

Re: APOD: Two Black Holes Dancing in 3C 75 (2022 Jun 05)
How would it be for anyone living in a solar system system like ours in between these black holes? Would the radition make life impossible? I wonder how it would look like from the night sky. Is it two black holes spinning around each other in one galaxy called NGC 1128? Or is it two ellipical galax...

I find this very fascinating but two things bothering me. Why are there more blueish galaxies that shows them much farther away for exampel billions light years more distant than more reddish galaxies? I also see plenty of green galaxies. How come they look green? https://upload.wikimedia.org/wikip...

Re: APOD: NGC 4565: Galaxy on Edge (2022 May 26)
How come NGC 4631 have so much higher star formation? How come it does have so much more bright pink emission nebulas? Dustlanes and the gas within them combine to create stars but not as effeciently as the pink nebulas which contains much more hydrogen and less dust? That is a good question that i...
