Starship Asterisk*

Oops! Yes, it looks like it! Thanks, Johnny! :ssmile: Ann Crazy! So by it's sheer size Andromeda still has a lot of stars compared to our galaxy. That's mind boggling! You can be fooled that seeing that picture you would think it's a ellipctical galaxy and not a spiral galaxy with arms. I wonder wh...

So, how many stars are there in M32? According to Hubblesite, there are roughly 400 million stars within a diameter of only 1,000 light-years in M32! That 's 400,000,000 ,000 stars. Therefore, if only one out of 400,000 stars is a red giant, there will still be 100,000 1000 red giants within a volu...

The second thing I want you to notice is the entire right part of the thick broad central dust lane, where absolutely no star formation appears to be taking place. Indeed, star formation in the Milky Way is winding down, and we are a "green valley" galaxy, transitioning from a richly star...

p.s. great close-up image AVAO! (but do you mean by "mirrored" that this is not the actual state of the galaxy but an optical effect? I'm not sure I understand) Astronomical images, by convention, should be presented with east counterclockwise from north. (And ideally with north up, but t...

Do they night skies actually look like that? That visually distinguishable. I saw the Milky Way bar once but it didn't looked that distinctive, it was much fainter but still impressive.

Nothing. The bubble is a hard vacuum.

Ok I see that's cool to know! What if we replaced the Alpha Centauri system with a Wolf Rayet star would we be impacted?

Can someone explain why we can't see any of the MANY satellites around the Earth in these photos from space? I'd think we would almost have a ring at this time as we have so many orbiting our world. Thanks! For the same reason we don't see any stars. It's a daytime image. Stars and satellites can't...

If one be in outer space just outside earth in a spacesuit would the surrounding looks exactly the same as in the picture? Or is it just a long exposure that makes everything so detailed? The atmosphere only makes a tiny difference in what the sky looks like. Being in space would make only a tiny v...

APOD 1 December 2023 annotated.png Milky Way rising. Image Credit & Copyright: José Rodrigues What I find most interesting about this APOD is the gray color of the main dust lane of the Milky Way. The color is due to a magnificent sprinkling of stars in front of the dark dust lane. Many of thes...

So the blue part over the red are full of quasars? How come they are blue instead of red? Shouldn't it be the other way around? Or is it because they are giving out so much blue light gamma, x-ray and uv light that they are more blue than the nearer galaxies?

How big is the explosion or the size of the nebula? If there's were a neighbouring starsystem with a earth like planet what would happen to it? The expanding cloud of material left over from the supernova now appears approximately 10 light-years (3 pc) across from Earth's perspective. That's the cu...

Beautiful image but you really see the galaxy disc and it's dust and H II regions so clearly?

As for the blue stars seen near the outskirts of NGC 2158, they are very, very likely outlying members of much younger (c. 175 million years old) and considerably more nearby (around 3,000 light-years) cluster M35. https://scx2.b-cdn.net/gfx/news/2020/1-openclustern.jpg M35 NGC 2158 Rolf Wahl Olsen...

How would it be living in that galaxy? Would the nightsky be black with lots of stars but no galaxy disc in it with an expeption of a big jet sticking out in the nightsky? add the boredom of red-and-dead star population: almost every star is a little smaller and yellower than Sun or is a red dwarf ...

Are the glowing waves from the most upper left reflections or bow chocks? Are you talking about these things? Part of APOD 29 December 2022 with arrows.png They are definitely not bow shocks. I don't think they are real, or rather: I think we are seeing some sort of reflections from inside the came...

What would happen if we were on the edges of that gas cloud? Would it have any effect on the solar system? It obviously would if it goes super nova.

The blue bright stars a top of the nebula are they also at the same 1400 light years distance? The bright blue star at the top of the nebula, SAO 10287 or BD+69 1231, has a Gaia parallax of 2.6998 ± 0.0139 milliarcseconds, which puts it at a distance of ~1,200 light-years. And yes, the nebula is at...

Would there be any sunlike stars in that tail? I do see a lot of blue stars. Imagine the view if the solar system would be in that location. The galaxies would take up a big chunk of the night sky.
