Life? Probably. Something that has thinking capabilities? Much more doubtful.

So you're saying out of the trillions upon trillions of stars that the chances are no life can think but us? I think the odds are that at least one of them does.

There may be countless other planets with intelligent life right now, but... if it took them millions of years to evolve... and they're millions of lightyears away... we might have to wait millions of years for signals to reach Earth from the eldest civilizations in the closest galaxies.

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

In another way it's really cool to be able to "see the past" even if all we see is always the past. At this level it is like a super power. If only some aliens had put a mirror somewhere far so we could see ourselves too. Or multiple mirrors at different distances. With enough mirrors and light bouncing around the size of the universe itself can be a "storage media" of the past with different photons all around carry…

Well that sounds like a good premise for a scifi book or movie.

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.

Humans are great at turning a new insight into a way to feel better about themselves compared to others that haven't had the insight. We are driven by our ego, so I find that very unlikely.

Why would we have to wait? Why would you assume that they're only sending signals now? Why would you not assume that they had a head start on sending signals before us?

One proof is that we are thinking, and so are dogs, cats and monkeys to a lesser extent.

That's Earth. There is no model to say that life always goes on that way. We just have no clue.

FOH with that solipsistic nonsense

Wir mussen wissen. Wir werden wissen.

We're multiplying a very large number (number of planets) with a very small number (chance of intelligent life). The margin can make the answer go either way.

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 bill…

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.

You're not going to see like galaxies moving, only very very close stars.

But you would spot transient phenomena like supernovae.

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. :)

It’s ridiculous. That final zoomed in image that showed one galaxy has maybe 300 million stars in it. Just that one. The scope is… unbelievable silly.

Watching this is ... hard to find the words to describe it. It's insane!

It shows us how mind bogglingly vast the universe is and how we're literally nothing compared to it. Paradoxically, it also makes me feel incredibly potent and capable as a human being in that being this small we can know so much!

Your size is to the distance of that distant spiral galaxy (420 Mly - 10e24m) as a neutrino is to you (effective cross section of a 1MeV neutron = 10e-24m: https://en.wikipedia.org/wiki/Orders_of_magnitude_(length))
