One of the things that awes me is not a pic but Voyager 1.
Having operated for 37 years, 11 months and 28 days, the spacecraft still communicates with the Deep Space Network to receive routine commands and return data. At a distance of 132 AU (1.97×1010 km; 0.00209 ly) as of summer 2015, it is the farthest spacecraft from Earth.

On August 25, 2012, Voyager 1 crossed the heliopause to become the first spacecraft to enter interstellar space

About 34 years just to get away from the influence of the Sun.
Voyager 2 is not quite as far, but close.
 
If you've seen the Hubble Ultra Deep Field image - all those galaxies so far away, just wait until the James Webb telescope is operational. At the time they did the Deep Field image, a lot of people were upset that they were "wasting" so much of Hubble's time staring at such a non-descript section of space. Now, with Webb, that's one of the first missions - to stare off into the distance. It should be able to see a LOT more galaxies that are so far from us, that they're red shifted out of the visible spectrum and into the infrared (which it "sees") - Hubble was staring at visible light.

me too ...then my question was - what does the data from Vger1 look like 😕
A) 0's and 1' s

Doh!🙄

What's even more amazing is the universe is still expanding.

I wonder how many of those stars still exist in the deep field images? :hmm:

When I'm at the beach and look out across the ocean I feel humbled. When I think in the scale this topic talks about I feel like an atom but I doubt that is even close to an accurate description. Perhaps that is why were compelled to be part of something bigger than ourselves.

Lots of info here too:

#10 in the OPs link is pretty cool too.
You go outside at night & think "look at all those stars... look how big space is.. i can see forever".
Then the more you learn... all that stuff you see is right in your back yard basically.

Thanks for all the pics every one.
 
this one always gets me:

how unlucky Christians will be when they are sitting in heaven staring down on that dark era 😉

So going by the spatial volume of the Universe, matter is nearly nonexistant.
Looks like the same holds true when looking at the dimension of time.
Our "Big Bang" is more like a brief pop.

With eternity available, you've got time to see the birth and death of countless universes.
Though if your brain still has the same capacity and capabilities as your standard-issue primate brain, you'll eventually forget this universe completely.

Or cut the Dark Era short. After everyone's satisfied that everything in the Universe is dead, format&reinstall: Pop a fresh singularity out of subspace and see what what kind of universe splatters out of it.

The size and scope of the universe is truly humbling.

And we act like our petty little problems on Earth matter. They don't. ^_^

It's all a matter of perspective.

What is really crazy is there are probably thousands of other life forms out there doing their own thing, hell with FTL travel but they probably don't even know about all the other life forms just because there's no practical way to just "get there".
 
It's rather unfair that we can observe all this shit, but will never get to know more that what we can observe via telescopes and other observation devices. I'm of the belief that faster than light travel is, and always will be impossible, so we are akin to a fish peering through it's fish bowl. Whats on the other side might as well be nothing but a pretty picture to gawk at.

If the proton of a hydrogen atom was the size of the sun on this map, we would need 11 more of these maps to show the average distance to the electron.

Yes, as if it wasn't bad enough that the immense majority of the Universe's volume is empty space not occupied by matter, even matter itself is almost entirely empty space by volume.

I like the idea that you never need to move faster than light, if you start toying with spacetime itself - warp drive. That's what this project is hoping to find, at least at a microscopic level.

You don't need to move through space faster than light if you can move space itself.

Drake Equation.
That's looking at detectable signals. Not only would you need the included factor of civilizations that can release detectable signals, but also then factor in the number of those that would want to release them.

Maybe a civilization releasing signals into space is like a mouse wandering across an open field, wearing bright orange and banging cymbals together.

Large-scale natural selection rewards "quiet" civilizations by permitting them to remain out of view of predators. Loud, sociable ones like us draw attention, and are "selected."


That's just signaling. Then there's visiting.
"Yes, I could develop this technology and go visiting, but I just can't be arsed to do it."
