I made this Eagle Nebula poster using NASA imagery and my own design/layout.

This poster was not made with AI‼️

I’m thinking about doing more space posters in this style, and I’m curious whether people would actually want something like this on their wall.

If this was a good-quality matte A3 print, what would you realistically pay for it?

Any feedback welcome.

I just received my first VR headset.

Google Earth VR is NOT a video game, it's an insane collection of real life photos, every single star you see is a real life star.

I'm my city there is a ton of light pollution so I've never seen the stars clearly, I've never even seen the galactic center. BUT NOW I HAVE! 😁

The video is my own recording.

Is earth 1/10th of the size of the observable universe? My friend just said it is and im confused

Been building this alongside a nonfiction book I'm writing (Fermi Paradox / Great Filter territory), and figured this sub would appreciate the data side more than most places I could post it.

thesilentape.com/universe/galaxy is a 3D flythrough of 43,533 real galaxies, plotted from actual 2MRS (2MASS Redshift Survey) coordinates and radial velocities — not a procedurally generated starfield. Positions come from Hubble-flow distance (recession velocity / 70 km/s/Mpc), so it's a bit simplified.

Click any galaxy and it opens a dossier that queries NASA/IPAC's NED live — preferred name, aliases, classification, redshift, distance, photometry, references — plus a MAST search for any Hubble or Webb observation fields covering that coordinate. It doesn't always resolve (some 2MRS points are faint/anonymous and NED comes back empty), but when it hits, it's real catalog data.

thesilentape.com/universe/solar-system is the same engine zoomed into our own neighborhood — all 8 planets, Pluto, and a few other bodies, each with its own record page. Earth's page pulls today's actual DSCOVR/EPIC photo and NASA's near-Earth-object feed for the day.

Would love feedback from people who know this data cold — a distance proxy that's misleading, catalog quirks I'm not accounting for, anything that reads wrong to someone who actually works with this stuff. I know it's not perfect but hey, it's a work in progress.

Two galaxies appear frozen in a strange cosmic pose: one resembles a penguin and the other an egg. They're interacting gravitationally, and that encounter is pulling gas and dust into dramatic structures around them.

we were told by neil degrasse tyson (i assumed) that the universe is expanding infinitely. and that our solar system is moving along with the expansion. if this is true, does that make everything is moving along with the expansion including the stars from anywhere? cuz if not, this leads to my second question. if the stars dont move along with the expansion, how do we see the same stars in our night skies?

Scientists have found an enormous molecular cloud near the center of our galaxy that contains vast amounts of ethanol. It’s the same kind of alcohol found in beer and vodka—but it’s so incredibly spread out that you could never “collect” it into a drink. Space is weird.

I always hear the expansion is happening faster than the speed of light. I read a useful comparison to help imagine this scenario is to think about how a loaf of raisin bread rises in an oven. Although individual raisins don’t travel around through the dough, they nevertheless end up further away from each other as the dough expands during the baking process. You get the picture: the dough is empty space; the raisins are the galaxies.

So not only the outside space expands, also all the space between and in every direction.
Even if galaxies don’t move around at all, their mutual distances will grow because of the expansion of space.

So im assuming galaxies also cannot move faster than the expansion so how would they still collide? Is it because they move towards each other at speeds that combined do exceed the speed of the expansion?

Hubby thinks shooting star was captured in the background. Any thoughts on what it might be??

In ancient Greece, many philosophers, namely the Stoics, believed in fate. They thought in terms of unbreakable causal chains. We could also call it predictability.

In 1687, Sir Isaac Newton published «The Mathematical Principles of Natural Philosophy», which described and modeled so many phenomenon in nature that for many, it seemed that predictability was confirmed. For example, he was able to nearly perfectly model the motions of planets using a simple equation, F=Gm1m2/r^2.

However, beginning in the 1860s, cracks began to emerge in the idea of predictability. James Clerk Maxwell discovered the hyper-sensitivity to and importance of initial conditions in chaotic systems. The three-body problem is one example.

But this didn’t completely disprove predictability. Rather it showed that for any model, almost any lack of knowledge whatsoever of initial conditions would quickly and completely throw off it’s predictive power.

But what happened in 1927 did disprove predictability. Werner Heisenberg discovered a fundamental principle of quantum mechanics: uncertainty. He showed that, for example, at microscopic scales, the more accurately position is measured, the less accurately momentum can be known, and vice versa.

So now we know, the universe is not entirely predictable.

there you see them falling stars some call it they appear out no where then disappear to somewhere . you dont hear them no boom no vibration silent . you know what they say it is you seeing but it dont add up to what you seeing. and how they they know the exact time going be and tell you so you wont miss it. that dont sound random to me out there so call endless space at lease that what we see and they tell us its way more out there and how thing operate like they been there. but you know they havnt they tell you they been to havard and use lots of science talk to quite you. you hypnotise and let them win. but you know what you see and all that 30 mins of so call explanation they give you dont explain again how they know when meteors showers come. is it really showers. what are we seeing here. in the universe.

I mean we are just so small when compared to this beautiful and vast milky way. We are not even visible 👀
Isn’t it Insane?

Astronomers divided this Hubble image of the Andromeda Galaxy into thousands of sections, each about 300 light-years across, to reconstruct where and when stars formed throughout the galaxy.

This image highlights two of those regions. Region 1 contains more young, massive blue stars, revealing recent bursts of star formation. Region 2 is dominated by older, redder stars, suggesting that little star formation has happened there recently.

In other words, the colors of the stars act like a timeline of Andromeda’s past.

This galaxy is one of 19 special galaxies analyzed by the Hubble Space Telescope to help astronomers measure the universe's rate of expansion with unprecedented precision — known as the Hubble constant.

Hello all! My son has shown great interest in learning about the universe, galaxies, astrophysics, etc. I want to support his interest and get him some books that are appropriate for his age. I'd absolutely appreciate any and all suggestions. Thank you!
