Starship Asterisk*

It's hard not to ask oneself the question, "Why is it dark at night?", when one sees all those little galaxies as crystal-sharp grains of salt richly sprinkled all over Euclid's field. Ann And they say visible material is less than 4% of universe.. I have a hard time even understanding sp...

Thank you Chris.

Still some questions unanswered (from my original 1st post), hoping someone can provide their thoughts if not answers.. 2) Also I wonder how many planets one can expect to form in this disk and 3) What's the width of disk and would it be similar in size (width) so that planets can form at wide dista...

I wonder why planet forming ring is seen brightest, even planet is seen brighter than the actual star? Is it the way the image is taken and processed to show most interesting things blocking/diffusing star's light/brightness ? I'm guessing so. Also I wonder how many planets one can expect to form in...

Huh? It says it's only 50000 ly across.. So not that big. And it says it's one of the large galaxies in Virgo cluster. Really? Not sure and can't imagine if other galaxies in Virgo cluster (or even otherwise) would be smaller than this..

The "star bar" looks almost vertical

Yep, I almost didn't realize it'd be vertical. Thanks.

I think, the galaxy is IC 2041! https://upload.wikimedia.org/wikipedia/commons/7/73/IC_2041_DSS.jpg https://de.wikipedia.org/wiki/IC_2041 Yup - that's almost certainly the same object/galaxy we see so clearly in this APOD! Sorry, shaileshs. I said to you that there were no galaxies there, because I...

I'm wondering if they are interacting with a bright galaxy visible towards lower left corner (7-7:30 position on a 12 hour clock dial) ?

Wow, beautiful image. I wonder what are different objects scene in this photo - e.g. 1) 4pm (within shells surrounding star) - orange/yellow object with circular dots around 2) 1 pm Orange object 3) 10am top left edge - 2-3 fuzzy galaxy like bluish objects I wish the photo was published in a way whe...

Ummmm... "Bar of stars" ? Where ?

Wow.. never imagined there's so many with their paths around Sun that close (relatively) to each other and all planets. We have decent idea about none of the PHA's (ones we have discovered/identified so far) colliding with Earth in next 100 years, I wonder, what's the probability of them hitting oth...

Very interesting and intriguing. I wonder - 1) how come this region seems to have sooooooooooooooooooooooo many "red shifted" (super old) galaxies behind the foreground galaxy cluster and what's their age (how old are they). Normally in other gravitational lensing photos, we tend to see lo...

When the Sun gets nova, our Earth will be eaten and that will happen in 3937 as prophesized by Nostradamus as the end of the world. This can be scientifically proven by Arthur Clarke's novel The Songs of Distant Earth. Lol.. Whole world was going to come to an end on 21st Dec 2012.. And we are here...

To be honest, didn't find this at all any interesting. Gas (planet) merging into gas (Star). No traces left behind.. What's the big deal ? Nothing spectacular, no dent.. like mixing river water into ocean.. Also not sure why in 8B years earth will fall into Sun, I thought the Sun was expected to die...

Thank you so much for your detailed response Ann.

Multiple things (questions) top of my head - 1) Why jet stream is visible only on 1 side ? 2) Why jet stream is only red in color ? 3) What's the while "halo" filled all around the center ? 4) With such distorted (mixed eliptical/circular) shape, how do we even know/how can we define edge ...

People talk about many possible galactic (non human made) reasons/ways of Earth getting destroyed (e.g. CME, Asteroid, Gamma Ray burst, Disruption of layers in atmosphere saving us from X-ray radiation, Sun getting bigger in 5B years and gulping earth.. etc etc etc). I wonder if anyone has thought a...

Oh, "stars digitally removed".. I thought they'll say "With JWST piercing through dust using lower infrared vs what Hubble saw in optical light"..

Huh? I'm confused. I thought we see such (planetary nebulae) when the star explodes and material is ejected out.. Here, it seems reverse (the material will be sucked in to form a star) ? Oh well..

I wonder what's the BIG deal NASA folks are other people are making about that "edge-on" galaxy seen at 10 o'clock position.. Within the external sprayed cloud (orange portion), I see *at least* a couple more between 8-9 o'clock.. maybe there are more.. And unfortunately the star that expl...

I like the APOD from 10th Jan 2008 (https://apod.nasa.gov/apod/ap080110.html) because it shows all 3 individual and composite. Seems Ann has given same image above. I guess back then we thought the black hole at center was only 10 million times Sun mass, now we feel it's billion times, who knows in ...

At least to me (to a naked eye, without zoom), comparing center of "right top" zoomed into "right middle" - I'm a bit challenged to see how they are same.. ?

What's the name of that "intruder" galaxy ? Seems to be that eliptical galaxy w/ no spehrical arms and no band at the center.. And, surprisingly, it passed through this main galaxy, triggered such violent destruction/displacement as well as creation but on looks almost untouched in it's o...

Maybe a point from where one has a view of "full earth shape* can be considered as a boundary ("beginning of space around Earth") ? Just a thought..I'm curious what others think.. I can do that from a ladder. It depends upon what percentage of a hemisphere you want to require to be v...
