Starship Asterisk*

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'm a bit confused (and yes, I'm going to read up relevant things online). I thought nebulae were mostly remnants after supernova explosion.. And here, the supernova hasn't happened yet (expected in next few thousand years) and the nebula is formed out of just "winds" blown from star's atm...

Beautiful view. Just wondering about all these blue stars seen adjacent to the plane of galaxy. Normally, with naked eyes or even the telescopic photos I've seen of our milky way plane, we see bluish hue background adjacent to the plane but the thousands of stars we see there are normally seen white...

Red colored is because of Hydrogen, i also see greenish tinged on left side (Oxygen ?).. Yellowish/brown in middle seems to be dust and visible yellow light around disc.. What about light blue? Spiral arms ? If no, what is it ? If yes, why are they seen so hazy cloudlike w/o any recognizable shape (...

3 questions top of my head - 1) Why multiple disks ? Can there be 1, 2, many ? How many and depends on what ? 2) Why opposite side of jet is disjoint (floating) as if it has no connection with source (jet coming towards us seems more uniform comparitively) 3) Any idea if plane of disks is determinis...

I wonder if those BIG bluish/white stars (some at inner circular boundary and towards outer circular boundary of photo) are part of this GC ? Are they seen much bigger and brighter because they are closer OR they are really big supergiants ?

I wonder why every encyclopedia is shy to tell the angle of this galaxy disk to our line of view. I found these 2 pages which say it's approx. 87-88 deg tilted - 1) http://www.nightskyinfo.com/archive/ngc4565/ "NGC 4565 is inclined to an angle of 87°, 3° from edge-on." 2) https://academic...

Background stars tooooooooooo faint to be seen (compared to bright light reflected from earth) I'm imagining .. ?

Sorry to say, today's APOD content might be "super cool and/or extraordinarily amazing" for some but for me (a lay person), honestly, I am not enjoying it much. Seems some *random imagination of super complex things we really don't know much about*.. And the music (background score) makes ...

I wonder - What's that bright light circular object seen at the center (where black hole is suggested) in base image which seems to have disappeared in inset at top right ? What was it? Where did it go? Why?

I'm assuming whatever is shown inside Einestien ring/circle are the copy images of real stuff outside because of gravitational lensing. If yes, after the merger is complete, I was thinking all that stuff will be cleared (copy images removed).. No ?

Over 5kms ? Means more than 5000m. Means more than half of Mt Everest here on earth. Does it look that high in picture (even if from distance) ? to me, it doesn't seems like even 5000ft high.. No ?

Chip in the camera lens?
Spacebug splattered on the "windshield"?
Or just a (boring!) processing glitch?

Yep, I was wondering exactly same.

To add to (or perhaps misunderstand!) Ann's posts, I like the pic of M53 from https://en.wikipedia.org/wiki/Messier_53 better, since it seems to more clearly show individual "blue stragglers": M53.JPG But are they actually "blue stragglers"? And frankly, I seem to see the same n...

>> If our Sun were part of this star cluster, the night sky would glow like a jewel box of bright stars. I'm wondering Is there a simulation video or even a photo of artist's imagination of this ? What a sight it'd be. What's the closest 2 stars are near the core of this cluster ? I'm guessing close...

It's beautiful (artistic, creative, imaginative, efforts to get it right) but thinking from "perfection" perspective, maybe they fell short? To me, the moon doesn't seem full seems a day before full moon. Yes ?

I wonder - 1) All objects without spikes are galaxies then ? 2) What's the blue spike/colored star towards top right corner ? The bright blue star is HD 205514. It is a star of spectral class A0, not unlike Vega. The star is located some ~ 1.000 light-years away, and at that distance, it is a faint...

I'm wondering about this statement - "Of course giant elliptical galaxy M87 dominates the Virgo cluster". To me, M86 seems larger than M87. No ? Both seem to be of similar brightness and at almost same distance.. I didn't search a lot to see size, I'm just going to by my eyes. Although M87...

I wonder what's the radius of the view shown here (360deg around).. i.e. Objects from how far distance are covered in this view.. The image is a projection of an all-sky survey. It shows every direction in the sky. There is no distance limit in the image. If you mean the view is of entire sky "...

So what's cooking for tomorrow: a TikTok video of someone dressing their cat as Spiderman to desperately get attention, or something actually educational? LoL.. So true! You captured thoughts (and disappointment/irritation) in my mind. Seriously, I have been huge fan of APOD for last 10 years, I ha...

I wonder if there is/was any satellite/shuttle that was in a perfect position and angle near Venus where it's cameras would see Venus blocking full Sun behind it causing a ring around it the way we see it during solar eclipses ? I'm surprised no one has any answer/comment on my query. Normally by n...
