Hear me out, a little thought exercise. If the Holographic Principle states that our universe could be a hologram formed from 2D information on a lower plane, then it's entirely plausible for a black hole's event horizon to be that 2D plane, thus explaining the theory that we are living inside a black hole. But you might say that's impossible because the black hole would have to be more massive than our brains can comprehend. This thought process is not entirely true because we don't know what's inside a black hole or how big it is, but we do know that its event horizon stores information. All that would need to happen is for that information to be highly condensed, and then you no longer need a massive black hole. Thoughts?

For example; could I see a band of the Milky Way? I've never been able to see the Milky Way, but recently moved to a slightly more rural area 2 years ago, out of town. I'm not sure how to see it other than look in the sky from February-October. P.S. I'm in the Northern Hemisphere.

Hi there,

I saw an object (probably a satellite) steadily moving across the sky just below the Moon towards the North. Location: Navi Mumbai Time: approx 7:50 pm today I checked the Heavens-Above app but it only showed a couple of Starlink satellites but they seem off as per attached screenshot.

Any ideas if I'm missing anything?

This is by far one of my best images since I started my astrophotography hobby. It also demanded a lot from me, as capturing panoramas at minus 8 degrees Celsius with strong winds was quite challenging.

The image showcases the winter Milky Way arc during the current planetary alignment. Visible in the photo are Mars, Jupiter, and Uranus. Additionally, you can admire intensely red-glowing regions filled with hydrogen alpha, such as Orion’s Belt and the California Nebula.

Above my silhouette, the Andromeda Galaxy shines brightly, slightly veiled by some red airglow.

An unnecessary heads up Is that this image wasn't desaturated, just that I used AWB and it turned out gray like

First pic of Jupiter never taken one before and this is on an iPhone 16 (this is for all those who asked on my previous post)

What you guys think

Recently heard that the Earth is an oblate spheroid. However, when I look at other planets, they are spherical. Sorry if this is a weird question, but how accurate is it to actually call Earth an oblate spheroid.

Managed to get this picture of Jupiter tonight through the standard iPhone camera! Ik it’s not the best but can anyone help me with finding an app that is better for exposure and whatnot on iPhone so I can take more detailed imagery because anytime I try using the exposure on the iPhone camera it just appears as a line almost as if the planet is a line I will link a picture in the comments. But yeah let me know what you think of my first picture as it would mean a lot to hear from everyone. Any advice is appreciated thank youuu

my question was; could a rogue planet or celestial body, far from any other celestial body or stars, have zero or near zero spin? if the answer is yes, what would the effects be and what would we feel different if we were on it? lastly, if the planet had an atmosphere, would it impact anything about that?

now im guessing it would be perfectly spherical (at least much much more spherical than spinning planets) and that we would feel the same gravity anywhere on the surface of the planet at the same altitude. but i can't really think of much about it, i don't even know if a planet like that is possible.

I’m fairly novice at this hobby so I have a cheaper setup. Shot with a canon t3i dslr camera from 2011. 6.10 hours worth of quality exposures reveals gas and dust around Orion’s Belt. Questions or advice always welcome.

Being a Trekkie who just got a new smart scope, I would like to get an image of the fateful system from Trek lore, but on the Dwarflab App, Starwalk, Stellarium, every app, every website I've gone on to look for its location (which is supposed to be somewhere in the vicinity of Leo) its not listed ANYWHERE. It's not listed as CN Leonis either. I understand its a star with a lot of motion, so its position has changed a fair bit over the years, so I wonder if the coordinates on wikipedia are even accurate. I know there's nothing much to see, just an orange dot, but It's something I've set my mind too and am finding it to be quite challenging.
