Some of that zooming in made me feel pretty damn uncomfortable. It really is f'ing massive out there huh. Makes me wonder what this is all about, I'm sure it's something, I wonder what. :)
I think that too. That it's surely meant to be something. But sometimes I think what does "meaning" even mean? Does universe really have any "meaning", the term that humans invented and that even they are unsure of? Then, I think it's a big randomness, a random accident, a big joke, just happening with nothing to make sense of.
So many rules, laws, and systems for all of this to be random. Seems a waste of good code if everything is random.
Is an ecosystem random? What happens when one outside force is added to an ecosystem? There's plenty of examples around the globe of this.
Life doesn't 'find a way' and balance. The ecosystem is damaged, and often times destroyed by adding a single non-native species. That doesn't seem random does it?
Randomness should have error correction, as it's random. Doesn't seem to though.
It's just so crazy to me to see a galaxy 420 million light years away. That is so much time for what we're seeing to have changed. I presume life can form within that window given the right conditions, so to some degree it just feels a bit sad that the distance is so great that we can't actually see what may exist in this moment that far away
Fun to imagine someone or something out there mapping us as well. What a cool video. I think one of the best things about space travel will be the loss of ego we go through when we really understand how vast the world is.
We are a necessary but insufficient part of the proof of life. One cannot say "no proof" when necessary proof has been achieved. All that remains is a second example -- the first took several billion years to achieve self awareness.
Something that involves "thinking capabilities" in a form we would recognise?
That's always what I consider when someone mentions the Fermi Paradox.
Humans tend to barely recognise "thinking capabilities" in other mammals. There is intriguing evidence that plants "communicate" and "remember", and have been doing so around us for at least as long as mammals have existed with humans barely noticing and usually ignoring or criticising researchers who suggest that perhaps plants may be "thinking".
If we don't even recognise "thinking capabilities" in the plants that have been around us for as long as we've been around as a species, what're the chances that we would notice and recognise "conclusive evidence of advanced extraterrestrial life" when we saw it?
What is the probability that two raindrops land at the same time?
It is pitch dark. Could one raindrop survive long enough to at least hear the sound of another landing before it disintegrates?
Is the time between the drop striking the plane and the drop smashing apart so short that no drop ever hears another, or even sees evidence that any drop other than itself ever existed?
If it is a machine that can reproduce itself, growth, collect energy, use energy, do actions based on events, etc, then animals match this profile (perhaps even plants), and also, at some point computer will probably reach that goal.
Despite that, computers won't have a "soul", so where this soul comes from is a big mystery.
I'm not even sure that two humans can prove with certainty that the other ones has a soul, this is still an unsolved problem.
Trying not to be negative, but statements like this completely disregard the degree of thought and evidence that needs to be accounted for to make a reasonable statement that isn't just pulling an ungrounded opinion out of the air. I mean why exactly is it doubtful? It doesn't seem doubtful to many other very intelligent people, so perhaps you should back it up with a bit of reasoning or evidence.
I think at the scale of the universe life even thinking capabilities life is almost certainly inevitable.
What's not inevitable is that it can thrive, and survive to a galactic scale. That's not even yet certain for us.
Universe is too big, we're all too far apart. Civilizations come, civilizations go. Some may not be on a planet where even rocket travel may be possible - no source of energy dense enough. Some can get wiped out by disasters. Asteroids. It's happened on this planet a bunch of times.
It's like the Birthday paradox. It's likely 2 people have the same birthday. It's not likely that someone else has YOUR birthday.
That’s hardly proof considering these examples all share a common ancestor. I ask you, can you communicate with a slime mold? Even the slime mold is more similar to ourselves than any potential life we’d find elsewhere, as we share a common ancestor.
And thats just how life on earth happened to iterate in recent terms. For most of the history of life on earth, it was unicellular. It could have just as easily remained a planet of unicellular life for another few billion years if it weren’t for a few chance mutations that happened to be slightly more competitive over the background.
"Astronomer Frank Drake created a formula to estimate the number of extraterrestrial civilizations in the Milky Way. Adam Frank and Woodruff Sullivan modified the equation to calculate the odds that Earth was the first intelligent life in the universe. They concluded that the odds of Earth being the first are less than one in 10 billion trillion, which suggests that other intelligent species have likely evolved."
1 in 10 billion trillion is some pretty serious odds.
It does get more complicated if we factor in life happening quickly enough without an extinction event.
But after looking at images like this there is just NO WAY we are the only ones.
I don't really doubt that life with human-level (or greater) intelligence has evolved at least a few times.
What I'm more pessimistic about is how long such intelligence might live. How many civilizations reached a point of harnessing nuclear power and then wiped themselves out with nuclear war?
I think even that's perhaps a warped anthropocentric view of intelligence?
Think about other earth-centric scenarios, and try and imagine if dolphins or octopuses or fungus or maybe even insect colonies or plant ecosystems had "won" and become the apex lifeforms on earth instead of humans. I wonder just how different concerns like "civilisations" and "war" and "nuclear power" would have played out in those cases? I wonder if assumptions like "industrial revolutions" and the inevitability of scientific discovery being used in detrimental ways like we have done with nuclear science actually correlate with "intelligence"?
That 600 times zoom-in on 1% of the eventual survey of 1/3rd of the non milky way sky... Shows a couple of galaxies, which if the milky way is "typical" represent a couple of billion stars.
Suddenly 1 in 10 billion trillion odds doesn't seem so (and I apologise in advance for this) astronomical...
Typical galaxies the size of the Milky Way have 100 to 2,000 billion stars and could have as many as ten trillion planets.
That’s about 100^5, so one way to think of this is that if you categories these by any four properties (temperature, stability, hydration, day length) then you’d expect about 100 samples for any point in that 4D space.
So even if you believe Earth is unique along four critical metrics, there are about a hundred planets per galaxy that also have those attributes within a percentage point. If you allow some wiggle room then you have tens of thousands or even millions.
We know conditions here on Earth varied significantly more than 1% over billions of years and life survived and even thrived.
I think there's a pretty compelling argument that could be made that matter assembling itself into conscious beings follows pretty naturally from life itself, given a long enough time horizon and assuming the properties of basic elements holds constant throughout the universe which seems pretty likely.
I think you fail to see the sheer probability just from the number of galaxies and the timeline itself where life can form and extinguish in even few million years. Every planet in the universe gets various amount of tries over eons
I agree. There is a huge bias in our culture that we imagine a human supremacy. We are the top of the food chain we think. The masters of our world we argue, despite simple bacteria being superior in all environments compared to fragile sickly humans. We not only assume that aliens would think like us, we think they would even look like us with more or less the same body plan. We think they would have the same cultural sensibilites of exploration aboard a ship, of making treaties and even sharing technology. Even in this thread you get pushback from replies and downvotes from people who are almost offended that this would not be the case.
If you ever study evolution on the other hand, you would realize how fantastical these assumptions all are. No, life elsewhere if anything is far more likely to look like how it did for most of the history of life on earth: unicellular. People forget that even multicellularity, let alone an organism with an entire bodyplan, emerged from pure chance, and could have easily been wiped out or outcompeted for resources as soon as it came if it didn’t have sufficient fitness. How lucky it was for us that our ancient eukaryotic ancestors enveloped that first mitochondria. How different life would look today if that never happened and we never had such an energy source to actually support these later iterations, considering all life that exists today are directly descended from this single line. How supremely unlikely it all is to tread even close to the same path. How many potential paths are lost along the way and how many paths only emerged as a result of previous paths.
The mosaic contains 260 observations made between 25 March and 8 April 2024. In just two weeks, Euclid covered 132 square degrees of the Southern Sky in pristine detail, more than 500 times the area of the full Moon.
This mosaic accounts for 1% of the wide survey that Euclid will capture over six years. During this survey, the telescope observes the shapes, distances and motions of billions of galaxies out to 10 billion light-years. By doing this, it will create the largest cosmic 3D map ever made.
So my question is, what comes after Euclid?
Will the next one capture better details further out (if further is possible)?
Since it's apparently a 3d map (?) I'd be curious if they will re-run the scan and compare between the scans? Pure speculation my part, but that would be pretty interesting, surely.
600x zoom didn't seem to help from the 150x zoom. Wonder if we will ever be able to see actual planet surfaces or we need some other technology to do that, i.e, we should have small satellites every 10 light years. but this map is amazing and a good step forward.
Edit:
Was just thinking that image does us tells us something i.e, there no large artificial structures or billboards anywhere we can see. Maybe I watch too much sci-fi but honestly would have expected someone to build some huge structure around a star or planet, would be disappointing if no one does.
> there no large artificial structures or billboards anywhere we can see.
I half suspect the aliens who can construct structures large enough to see from lightyears away are by far most likely to be building Dyson Spheres around stars which make them significantly less likely to be seen rather than something we'd notice.
Man I REALLY hope we solve Dark Energy/Matter in my lifetime. That'd be so cool. I put it up there with long term habitation on another world (moon or mars is fine to me!).
I can never truly wrap my head around the time component here, this is 400+ million year old light! in earth terms, that's when most life was still ocean-bound
Really impressive work, thanks for sharing. The video, that is -- the astronomy is indistinguishable from magic and thus way beyond the reach of words like "impressive", obviously. I do find it a little funny that physics is in such a jam that "look at more stuff" is an important next step, but godspeed nonetheless.
ETA: For those who love space but are similarly OOTL on the specifics of modern missions: this is from a telescope launched to the L2 point (next to Webb!) last July, and is currently a bit over 1/6th of the way through it's expected lifetime.
In comparison to Webb, it's focused on ~visible light surveys of the medium to far range, whereas Webb was built for ~infrared investigations of very distant objects. It was budgeted around 1/4th the cost of Webb (and ended up being ~1/20th due to Webb's costs running from $1B to $10B...) See https://www.jameswebbdiscovery.com/other-missions/euclid/euc...
If you're looking for a new wallpaper, it would be hard to beat this 8000x8000 pic it took of the Perseus galaxy cluster, casually depicting 100,000 galaxies: https://en.wikipedia.org/wiki/Euclid_%28spacecraft%29#/media... The discoverer of galaxies, Kant, would literally weep. We're lucky to live when we do!
> I do find it a little funny that physics is in such a jam that "look at more stuff" is an important next step
Observation is the most basic step of science. By viewing, we can find evidence of theoretical concepts or see something that conflicts those theories so they can be discarded or tweaked. It's not like there are experiments that could be used to test theories, so observing is all there is
Life on Earth is the same. If we are to get off Earth, we need to know what life to bring with us. We need to look a lot more, and much more closely at all the evolutionary products out there to make those decisions (if we arrogant humans can indeed even manage the intricacies of such an endeavor).
I agree wholeheartedly with all of your sentiments, but I don't think that Kant discovered galaxies or had much interest in them. That honor goes to Messier or Hubble, I believe.
Messier catalogued many objects, some of which were galaxies, but he did not know what they were. It was Hubble who first figured out (in the 1920s) that there were definitely separate galaxies.
We still have a long way to go to beat this draw distance, but we are on our way. The day will come when we have "sentient" beings, living in a massive world created by us. And they will ponder the same things as we do now.
And we will remain invisible and out of reach, but completely observant, and influential in their world. After all, we wrote the program.
And they will study the code and discover their own "natural laws" and invent their own things.
And they will progress until they create a completely simulated world of their own.
I wonder at which level are we. How many sims down from the original program...
But I'm not a brain in a jar. That is not my experience.
The benefit I get is knowing that this is not all one "big bang"
We are so quick to laud our own achievements, but fail to give credit where it is due.
We build nuclear power plants, waste water treatment plants and the beginnings of quantum computers. And we congratulate ourselves for a job well done, after spending an unspeakable amount of resources on them. We maintain them with a constant labour force, regular maintenance shutdowns and a ton of money.
Meanwhile the sun keeps shining, the clouds keep raining and your mind keeps minding.
And they do it on zero budget. No off days. No staff. Automatically.
And with all this engagement, the energy remains the same.
I wish there was a standardized way to let folks who run a website such as this one know how much a casual passer-by viewer enjoys the byproduct of their work.
If you're in the EU (particularly Germany, France and Italy, who are the three largest funders), you can let your representatives know you appreciate ESA's work.
You are of course right that there are lots of potential motivations for spending extra time on the page. But it will likely be interpreted as enjoyment in the absence of other feedback mechanisms.
If you'd prefer not to watch a video, try this page [1] that has images.
Hopefully there will be a zoomable image (like Google Maps) eventually.

it's not even clear what the edges are but I think it's fair to say that the bigger it is, the more complexity you can probably cram in there
The Cosmic Deep State went to great lengths to make all of this very.... big.
Too big to fail?
I think that too. That it's surely meant to be something. But sometimes I think what does "meaning" even mean? Does universe really have any "meaning", the term that humans invented and that even they are unsure of?

Randomness should have error correction, as it's random. Doesn't seem to though.
My money is on it just being a playing field for the game of life. A damn good one at that.
Wondering is the what.

That was said when we first orbited the Earth. Right now many things - space travel in particular - seems correlated with vastly increased ego.
To think that it's only been a touch over 100 years that we've even had confirmation that other galaxies besides our own exist.
Prior to that it was thought that the entire visible universe was around 100,000 parsecs across (what we know now to be just the Milky Way.)
So many solar systems out there, life evolved in many planets for sure. No proof but no doubt.
No, there's only one solar system in the entire universe. There's countless star systems though, but only one of those stars is named Sol.

I think the odds are that at least one of them does.
It depends what you call Life.

Sadly, that's looking less and less likely as time goes on.
One proof is that we are thinking, and so are dogs, cats and monkeys to a lesser extent.
That’s hardly proof considering these examples all share a common ancestor. I ask you, can you communicate with a slime mold? Even the slime mold is more similar to ourselves than any potential life we’d find elsewhere, as we share a common ancestor.
That's Earth. There is no model to say that life always goes on that way. We just have no clue.

There is zero way to optically resolve an exoplanet’s surface without something like a gravitational lens.
If light is hitting it, can you explain why not?
Can't we build a giant optical interferometer in space by sending multiple telescopes out there?
I’m still loooking for intelligent life on this planet!
Man I REALLY hope we solve Dark Energy/Matter in my lifetime. That'd be so cool. I put it up there with long term habitation on another world (moon or mars is fine to me!).

Aliens, but it's classified, so they redacted those parts.
