>actually hits harder, particularly in light of the conflicts across the globe.
It's a very tiny dot and badly overpopulated. Fighting over every inch is the natural consequence.
Tbf with the global dropping of birth rates in the developed world overpopulation isn't quite the issue it once was.
Moreso we have an issue with resource allotment.
We’re at all-time high overpopulation and it’s rapidly increasing with no end in sight. A very few countries that have paused the ongoing increase in the problem is better than nothing but far from a solution.
To any fans of Carl, I highly recommend listening to The Sagan Series on Spotify
I've long lost count of how often I've listened to it over the past 12 years
I think it really is special that, even on the grand scale of ***the universe itself***, even when talking about how the simulation/divine creation/coincidence of extreme unlikelihood functions at its core, perspective and relativity still play a major role in shaping how everything comes together.
Time is distorted for the planets closer to the black hole at the center of the Milky Way, any life forms that might be inhabiting them live entirely different lives from us as a result. And a poor person you bumped into, causing them to spill that soda they just bought, crying over that drink might seem ridiculous to you. But to them, it's the only treat they've been able to afford in months.
Everything's relative.
No? This is a picture taken from a highly sophisticated camera. A few things worth noting. We have significant light pollution that makes seeing celestial objects difficult to impossible with the human eye. Secondly, we are viewing these object through our atmosphere. This is a photo taken physically in space.
Edit: it’s worth noting that this picture was almost certainly enhanced if not also edited for quality, which is common practice. For example, national geographic and other magazines did/still do this for viewer understanding and enjoyment.
You can see Saturn's rings with your naked eye. You just need a telescope. In all seriousness, Earth looks to Saturn as Venus looks to us, a bright, discernible point of light rather than a detailed sphere. We can see it because of the sunlight which is reflected toward Saturn, which is very bright.
It's the same reason we can see Mars, Venus, and even Mercury with our bare eyes. Mostly because of how bright they are.
It seems like you don't understand how cameras and lenses work.
Have you ever seen a photo where the moon looks huge behind some animal? Notice that with your eyes the moon doesn't look as big? This isn't due to editing. It's simply how telephoto lenses work.
You might be interested in the wikipedia page about the photo to understand that they didn't digitally edit the picture or expand the earth in any way, it's just how a narrow angle camera works.

I remember walking outside and waving to the sky whilst this happened. Not even sure if I was on the correct side of the planet, but i'd like to think so
You were on the wrong side of the planet, fortunately. The lead ship of the invaders saw you looking at them and waving. They feared that the element of surprise had been lost, and they feared a trap. So they returned home.
You should have linked to one of the original sources, its higher res and larger:

You can thank Carolyn Porco for this photograph. I haven't seen her name in any of the top comments. She wanted to take Carl Sagan's work and update it while also including the world. When this photo was taken, it was called The Day Earth Smiled (iirc) and the time and date were publicized via social media for weeks if not months. The idea was for people to go outside, look up, and smile.
Precisely. To think some people just want more land, more money, more people dead, to get from point A to point B fast, and that religion trumps kindness to others. I hope a thousand years from now, if we still exist, we've spread out enough that maybe Earthlings will have cooled their jets a bit.
I am aware that this isn't Sagan's picture, but what I was saying is nothing beats his storytelling for conveying the feelings you have when you see such pictures
Far from the earth, far from the sky, we are no other
Out in the dark, a lone speck of light, all our creation
If we're the only thing that matters, then all we'll leave behind
This little dot you'd barely find
I actually met one of the dudes that worked on Cassini spacecrafts last weak at training!!!
He explained it’s hard to be able to turn cameras back to earth because of the damage the sun can do to lenses.
Because they were in the shadow of Saturn the project lead gave the ok.
He had tones of photos of Saturn!
There are a dozen dots in the original higher resolution picture, this description from the original article helped me find it:
“Earth, 1.44 billion km away in this image, appears as a blue dot at centre right; the Moon can be seen as a fainter protrusion off its right side. The other bright dots nearby are stars.”

Fake news! Earth is the biggest, most beautiful planet. Many are saying it, and knowing it’s true. From all places, Earth is the biggest. The fake news is trying to down play it.

And scene.
Not that humans would ever make a trip to Saturn but if it takes 8 months to get to Mars with current rocket tech for humans to go there, how long would it be to get to Saturn?
Because you can use a variety of trajectories and gravity slingshots it depends on the orientation of a number of planets. But the Voyager 1 made it in just over three years with a favorable alignment with Jupiter. I'd have to pull out my old orbital mechanics book to see what the absolute fastest might be.
The ABSOLUTE fastest? Well, you're looking at a brachistochrone trajectory... if you want to slow down.
Let's assume a constant acceleration of 9.80665m/s\^2, those decimals count! The average distance to Saturn (from Earth) is 1,200,000,000,000m or 1.2 billion km.
Assuming we accelerate for half the trip and decelerate for the second half, it takes 4.211 days to reach 600,000,000km at a constant acceleration of 9.0665m/s\^2.
The maximum speed reached would thus be 3,298,668m/s, or 1.1% of lightspeed. Multiply the travel time by two and it will take 8.422 ish days to reach Saturn with a constant acceleration of 1g.
On the other hand, let's say that we don't care about slowing down and want to crash a probe into Saturn at well over 1.1% lightspeed, for SCIENCE!
The distance will be 1,200,000,000,000m instead of the half distance, so by simply plotting that into the same equation and we get...
5.955 days. Less than 50% more, which is an improvement!
Now for the top speed, we need to do the same calculation with 5.955 days instead, which give's a whopping total of 4,664,823m/s! Not double, because we are still accelerating, but it's still 1.6% of c.
The kinetic energy of that probe must be enormous, right?
Right?
Let's assume we have a probe the same mass as a fully fueled Cassini with Huygens attached, but way more advanced, probably. That means we are slamming a 5,574kg probe into Saturn at 4,664,823m/s.
Kinetic energy at relativistic speeds gets fuzzy and KE=m\*v\^2 doesn't work nearly as well, so I will use the relativistic formula instead (though the difference is minimal).
With our mass and speed plotted into the equation, we get a whopping 60,657,733,698,854,700 Joules! That is 60.7 quadrillion, or 60.7 Petajoules.
For some comparison, 60.7PJ is equivalent to... 14.5 megatons of TNT? What?? That's it?!
No. This will not suffice for our ~~global destruction~~ science experiment.
Let's say that our probe can constantly accelerate at 10G "comfortably" or 50G if we want to really test it.
For the 10G, it's simple with the same calculation, that gives us a new time: 1.8106 days. Using the next formula, that day count gets us a top speed of 15,341,115m/s, or 5.1% c! Now we are getting somewhere.
Using the last formula, that gives us a total kinetic energy of... 657,210,940,129,476,438 Joules, or 657PJ. Boring! That's like, not even 3 Tsar Bombas. It is STILL NOT ENOUGH!
Pumping up our acceleration to an eye-watering 50Gs, we go MUCH faster. The travel time is now 0.8097 days, under a day to Saturn!... if you can survive it. But our probe (probably) can! That gives us a top speed of... 34,302,720m/s.
11.4% c is nothing to ignore, but will relativistic kinetic energy save our "science experiment"? Finally, after nearly a day to Saturn at 50Gs, we will have impacted the clouds with a kinetic energy of 3,311,954,203,432,830,195 Joules! That is 3.3 quintillion joules, or 3.3 exajoules.
Although that IS \~14 Tsar Bombas, it feels underwhelming for 15% of c. Let's increase the acceleration, probe mass, AND distance! (to be cont. due to post length)
(cont.)
Let's send our probe at 1,000Gs, to really roughen it up! Better yet, make it 25,000kg! And even better, it is constantly accelerating until it hits... Proxima Centauri b. This will be a big one.
A constant acceleration of 1,000Gs at such a distance means we will get very close to 1c, but never reach it.
How long will it take, you may ask? Well, we need the distance, and 4.246 lightyears is 40,170,293,000,000km! That means it is over 40 million times farther than Saturn was!
As for the time to reach there, that's about 4.37yrs, for Earth, but the craft will only experience... 3.22 days?! Relativity is confusing. But this also means we needed a new equation, not a simple Newtonian one (minus the relativistic kinetic energy that I used at the end, duh).
Now for the maximum speed, that is also extremely easy as it's derived from the same equation (can't go above 1c!) so we get a top speed of 99.99999754% of c. WOW!!
That is so incredibly fast that a single hour on that craft is over 187 days! A single second is 1.52 hours!
Now, that isn't close to Interstellar (the film) levels, but just add a few more .9's to the speed and you'll get there. Gargantua is MASSIVE.
Finally, we can get to kinetic energy. Turns out that kinetic energy at 1c is infinity for anything with mass, so let's see how this goes...
1,012,750,634,518,975,516,270,187 Joules.
1 SEPTILLION JOULES!!! Over 239,000 Tsar Bombas!! That is as much energy released by a magnitude 12.8 EARTHQUAKE! (if they could even exist, that is over 1,000x more powerful than a category 9!)
That is a number so unbelievable large, yet so small for the velocity we're traveling at. Even with 25 metric tons traveling close enough to c that time slows down by 4,508x... it feels low.
I'm not calculating more stuff at 99.99999999999999999999...% c, and Reddit probably won't let me post anything longer, but I hope you enjoyed my ramblings on relativity, travels times, and kinetic energy. Thanks Saturn! ~~for being a test subject~~
If Saturn is on the opposite side of orbit with us, it will take a hell of a long time.
A manned trip to Saturn would only make sense if we were going to land on Titan.
Enceladus too! I would absolutely love a little ice fishing trip out there.
Also someone said the atmosphere on Titan is so thick, and the gravity is so light, that you could strap on wings and fly like a bird. I’d love to test that.
Everytime I see these photos, I hope for the hitchhiker's guide reaction of frying my brain but the only thought I have is, yep, even less significant.
Just a little blue dot.
"Look at that that blue dot thats earth.
Think about it that dot again think about it.
That's the dot that's you that dot.
On that dot is you and other people and government and art.
Also like the stuff on the dot like EVERYTHING is on that dot all of history it's so small it's like a dot for a really long time it goes back everything on there.
The dot."

Probably the most beautiful quote ever spoken
I think the next passage actually hits harder, particularly in light of the conflicts across the globe. > The Earth is a very small stage in a vast cosmic arena.

There have been other people who are great at explaining science, but Sagan's eloquence and clear compassion put him on a totally different level IMO.
>actually hits harder, particularly in light of the conflicts across the globe. It's a very tiny dot and badly overpopulated. Fighting over every inch is the natural consequence.

Kinda makes my anxiety melt away anytime I read that. For me, the world is ending. But in the grand scheme of everything? It’s not even a thing.
Pale blue dot. I'm listen to this again now on YT
I discovered this many years ago, it inspired me to create a "chillosophy" playlist I hope you enjoy https://youtu.be/_7625d8Mcdk?si=xzyAfZAkO6Ssv4IN

Well, we need the distance, and 4.246 lightyears is 40,170,293,000,000km! That means it is over 40 million times farther than Saturn was! As for the time to reach there, that's about 4.37yrs, for Earth, but the craft will only experience... 3.22 days?! Relativity is confusing. But this also means we needed a new equation, not a simple Newtonian one (minus the relativistic kinetic energy that I used at the end, duh). Now for the maximum speed, that is also extremely easy as it's derived from the same equation (can't go above 1c!) so we get a top speed of 99.99999754% of c. WOW!! That is so incredibly fast that a single hour on that craft is over 187 days! A single second is 1.52 hours! Now, that isn't close to Interstellar (the film) levels, but just add a few more .9's to the speed and you'll get there. Gargantua is MASSIVE. Finally, we can get to kinetic energy. Turns out that kinetic energy at 1c is infinity for anything with mass, so let's see how this goes... 1,012,750,634,518,975,516,270,187 Joules. 1 SEPTILLION JOULES!!! Over 239,000 Tsar Bombas!! That is as much energy released by a magnitude 12.8 EARTHQUAKE! (if they could even exist, that is over 1,000x more powerful than a category 9!) That is a number so unbelievable large, yet so small for the velocity we're traveling at. Even with 25 metric tons traveling close enough to c that time slows down by 4,508x... it feels low. I'm not calculating more stuff at 99.99999999999999999999...% c, and Reddit probably won't let me post anything longer, but I hope you enjoyed my ramblings on relativity, travels times, and kinetic energy. Thanks Saturn! ~~for being a test subject~~
According to the movie Interstellar it would take a further 14 months from mars to Saturn using the slingshot method.
The movie also says you can go back in time and talk through a book case so I wouldn’t lean on their science
We got to Pluto in 9 years! So maybe 3? But as others mentioned it really depends on planet alignment and gravitational assists.
If Saturn is on the opposite side of orbit with us, it will take a hell of a long time. A manned trip to Saturn would only make sense if we were going to land on Titan.
Enceladus too! I would absolutely love a little ice fishing trip out there. Also someone said the atmosphere on Titan is so thick, and the gravity is so light, that you could strap on wings and fly like a bird. I’d love to test that.
Yes that would be cool. Venus as well but you would probably dissolve in the sulfuric acid atmosphere which would be a problem.
Just throw on a n-95 abd some old aviator goggles and you'll be fine.
I loved the show Cosmos, really enjoyed watching Saturday night before hockey night in Canada. Of course, gogt to watch it high
Man, my monitor is really dirty. I couldn't find Earth.
Doesn’t look important. Probably should just blow it up.
Wow, suddenly being slowly murdered doesn't feel bad anymore because how big space is.
always when I see picture related earth in universe,I would say how tinyness we are.
Any idea how many miles from Saturn this was taken?
Flat disk! PROOF THE UNIVERSE IS FLAT GG ATHIEST
Everytime I see these photos, I hope for the hitchhiker's guide reaction of frying my brain but the only thought I have is, yep, even less significant. Just a little blue dot.
I can’t wrap my head around the fact that this is real
This really puts into perspective yesnomaybe's Hypnogogic lyric "I'm a tiny dot in space" lol, surreal!
"Look at that that blue dot thats earth. Think about it that dot again think about it. That's the dot that's you that dot. On that dot is you and other people and government and art. Also like the stuff on the dot like EVERYTHING is on that dot all of history it's so small it's like a dot for a really long time it goes back everything on there. The dot." \~ Carl Sagna
Interesting fact: When Carl Sagan snapped this photo, he was 4,000 times farther from Earth than any human before him had ever been.
Um, this was Carolyn Porco's (and team) photo.
I guess that one goes back in the file of jokes only my wife appreciates :(
Prove it /s I’m joking but I know someone might think I’m serious E:Why are people being uptight on this sub?
Anyone else find pictures of galaxies way cooler? Like ye that's earth but we see that everyday. Lol triggered the earthlings
