Starship Asterisk*

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...

Who could have identified moon in that picture without hovering mouse over the image ? I bet not a single person. Right ? I'd say chances are higher that someone would say "why/how come that human being is holding a moon in his hands ?" ;-) .. Jokes apart, I have never ever seen moon in su...

It looks so beautiful. One thing I'm wondering - Closest to Earth on May 13 (so good chance we can see it during our night time), closest to Sun around May 27 (means we can't see it in our night time) but then someone predicts it'll be brightest in June means it'll get brighter after going around Su...

No mention of the size differences in the images? APOD-Soponyai-PenumbralEclipse_size.jpg And we are supposed to believe the green lines drawn along the edges are really perfectly parallel ? Not just drawn at the edges and tapering slightly ? ;-) Ha ha ha.. Just kidding! I know it's just a visual p...

A bit tangential question/topic - Do we really know how big is our own milky-way galaxy and how many stars and planets there are ? There is so much of ambiguity or variance, it feels it's such a wide guess (at times giving impression of such *wild* guess).. Some reliable sites say diameter is 100,0...

Something I've always wondered in large-scale galaxy images like this; are the groups of blue specks we see individual hot blue stars, or complete compact clusters of hot blue stars? There was an APOD some time back featuring a massive multi-megapixel image of the Andromeda galaxy, and I was never ...

There's a mention of another (thinner) galaxy - https://apod.nasa.gov/apod/ap141105.html It's not only thin but more interestingly it lacks dust (dust lanes/patches) which we are used to see+imagine in most galaxies. I wonder, what's the reason for lack of dust lanes/patches in such galaxies ? Is it...

Absolutely amazing and beautiful. I don't recall ever seeing such spotless (I mean, absolutely spotless!) Sun.

In "view from Saturn", why does the sky is seen bluish (like we see on Earth) ? In the past, in famous "pale blue dot" photos, the sky was always seen dark black. Similar to how it's seen for "view from Mercury". Why blue in this photo ? Thanks in advance for all commen...

I wonder why it's sooooooooo difficult (takes 3 years and several processing efforts) to figure out how it'd look to an unaided human eye.. If the spacecraft has regular camera (similar to what an ordinary cellphone has now-a-days) then an image taken in natural light (i mean, visible light, not inf...

Sorry if I've already asked this in the past. Whenever I look at such photos, I always wonder, which one of the bright objects (of various sizes, shapes and colors) we see are stars and which ones are galaxies. There are some photos wherein every object (almost every) is a galaxy. But, some have a m...

I wonder - How long does it take for ISS to orbit (complete 1 pass) across earth ? I thought it'd be 90min, today's APOD says 93min, but many other websites (including wikipedia, cool cosmos etc.) say it's 92min. In the day and age of precision in measuring time (x ray clock pulses from pulsars help...

I wonder what keeps the stuff in place on such objects ? Most bigger objects will have some core (like molten iron etc) to create gravity but what about these light and floating/wandering/drifting objects ? No core, no molten iron, then where's the gravity coming from ? Why the crust/surface objects...

Hello, I wonder - 1. why tidal tail of left galaxy and drawn out spiral of right bottom galaxy are not towards eachother ? Their direction gives no clue if there was any interaction between them.. 2. Stars with spikes visible are in our own milky way but - a. the objects without spikes - are they s...

I checked the "zoom" tool.. what a view at 2nd most zoomed level.. stars are next to eachother as if they are sand grains on a beach.. I wonder what's the smallest distance between any 2 stars in the densest region.. and, will there be darkness on any planet in one of those star's solar s...
