First Image ... 4.6 Billion Years Ago ... in a ... (Universe) ... long long ago ...

[doublethink]

President Joe Biden unveiled this image of galaxy cluster SMACS 0723, known as Webb’s First Deep Field, during a White House event Monday, July 11

Webb’s image covers a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground – and reveals thousands of galaxies in a tiny sliver of vast universe

Webb’s sharp near-infrared view brought out faint structures in extremely distant galaxies, offering the most detailed view of the early universe to date

NASA and its partners will release the full series of Webb’s first full-color images and data, known as spectra, Tuesday, July 12, during a live NASA TV broadcast

PS: James Webb will look back 13 billion years. Almost to the edge of time as we know it. Yeee ho ley !!!

1. Have to

37. *snerk*

Wow, Phil and Jerry are so young in this photo.

[Pluvious]

61. Silly Rabbit...

Trips are for kids !

Especially, the long, strange ones

[NewHendoLib]

2. Wow...life before any trumps!!!

Seriously, I am a huge astronomy buff. This is indescribable!

[FloridaBlues]

3. Yes it is . Mind blowing.

[speak easy]

4. .. far, far away ...

which one is Tatooine?

[doublethink]

7. Ha you are correct see post *6 in this thread ...

I love Tatooine !!! Hope the Webb Tele finds it ...

[speak easy]

11. 4.6 Billion Years Ago ...

maybe Alderaan is still there

[doublethink]

13. Hope so ... damn I love Alderaan too !!!

Alright plans canceled, I am watching the first 3 Star War movies tonight in my home movie theater. Great lead up to tomorrow morn. "May The Force Be With You" my friend.

[ShazzieB]

33. I hope they find Vulcan.

We could really use some of that Vulcan logic these days!

[ProfessorGAC]

42. That Shouldn't Be Hard

It's only supposed to be 16 light-years away, per Star Trek lore.
That can't be right though, because an ancient, but highly advanced culture would have had radio for so long that scientists would have picked them up in a heartbeat.
We would have known of their existence for 300 years by the timeframe of the classic series.
Sorry, kind of geeked out there.

[ShazzieB]

70. Oh, no apologies needed!

I love geekery, and Star Trek geekery is my favorite kind! 😁

5. All those streaks ...

are galaxy images that have been distorted by gravitational lensing by a massive object in the foreground; presumably that would be another galaxy. Gravitational lensing was one of the earliest pieces of evidence supporting Einstein’s general theory of relativity.

[denbot]

23. +1

Should have read down thread before my related post.

[doublethink]

6. Think I messed up the Star Wars quote though ....

think it was 'far far away' and not 'long long ago' but know it was a Galaxy that I changed to Universe. Seemed appropriate. Tomorrow with this and the J6 hearings ... wow.

[Wounded Bear]

15. I believe Far Far Away was Shrek...

[doublethink]

16. Alright I'm gonna start with "Pinocchio" 1940 tonight and work my way forward ...

to get the quote corrected okay lol. I'll get sidetracked of course with his growing lying nose and think of T&^*&P ! Naaa I'll pass ...onto Star Wars !!! But 'Sing a little whistle and always let your conscience be your guide!" Peace.

8. Yeah! I remember that. It was a Tuesday.

[2naSalit]

9. We're not alone.

Defining who the "we" is can be sticky though.

[fightforfreedom]

10. Look at all the aliens. who knew?

[brush]

12. Billions of galaxies, stars and planets, we are not the only ones.

[USALiberal]

17. Maybe there are, but no proof yet

[brush]

26. Not the other way either.

But with the billions of galaxies and trillions of stars and quadrillions of planets around those stars, it's a very good bet that conditions for life elsewhere has been sparked...and it may not be anything like what exists here on earth, or even carbon-based.

[USALiberal]

30. I wish we could get some signals at least Nt

[ProfessorGAC]

46. Just So Unlikely

Even an culture more technologically advanced than earth might only have started broadcasting 500 years ago.
The could be 600 lightyears away & we still wouldn't hear from them for a century.
It would be supercool, but the chances of us getting one is so small I quit considering it long ago.

[USALiberal]

47. Good points! Thanks!

[Shermann]

38. Most claims in the present tense regarding galaxies in that photo are unfalsifiable

You can make assertions about the light itself which emanated from them so long ago. But today, every galaxy in that photo has crossed over the Hubble horizon. Unless they magically reverse course and head back towards Earth, they will be forever causally disconnected from us.

94% of the visible universe's galaxies are permanently unreachable. We're more alone than many realize.

[Deuxcents]

14. Thinking of how Carl Sagan would be so delighted

[Sky Jewels]

18. Amazing

Photos like this make me wonder how any any human can think that the last few thousand years of the existence of one recently evolved species of primates on this one little planet amongst billions of galaxies are the main focus of some supernatural sky deity. Reality is so much more awe-inspiring than mythology.

20. I like that quote.

I actually find my insignificance very comforting.

[triron]

35. I know there is a god. It is the Higgs particle.

[Sky Jewels]

41. I'll bow down to Higgs

but I worship the Egyptian cat goddess Bastet as my lord and savior.

[Hermit-The-Prog]

21. It's raining galaxies! Duck and cover!

Actually, they're all being sucked into black holes and being sucked toward each other to make even bigger black holes so the whole universe is gonna die in a gravitational smush. Don't worry; it'll just result in another big bang.

See ya next go-around.

[brush]

27. Isn't it still expanding, not contracting?

[Hermit-The-Prog]

28. Give it just a little more time.

Maybe they're all just running away from us.

[Celerity]

29. yes, expanding, and will continue to do so until the last atom, last subatomic part of that last

atom, ceases any motion/energy, at which point EVERYTHING has thus ended, forever

at least that is one of the theories

I do not buy into any of them

we are far too unadvanced atm to even start to comprehend things of that magnitude

[triron]

36. I don't either. The Universe has a few surprises up its sleeves.

[keithbvadu2]

59. So many theories

[Celerity]

60. Yes. It is just not an area I have a lot of interest in. It's just not my cuppa.

I absolutely think it is vital work though.

More funding is needed for science, less for war.

[keithbvadu2]

62. Space and the human body and many more subjects. The more we learn, the more we find that we do no

Space and the human body and many more subjects.

The more we learn, the more we find that we do not know.

[denbot]

22. Look at all those gravitational rings.. Black holes everywhere..

Holy smokes..

[Sympthsical]

25. It's because of the supercluster

The one they used for this is considered one of the most powerful gravitational lenses in the known universe.

This was after only 12.5 hours of exposure. Hubble's deep fields took weeks.

I can only imagine what they'll find when they just aim JWST in some random direction for two weeks. So far, Hubble has gotten to 13.2 billion light years. In theory, we can go a lot farther. In theory.

So this will be really interesting.

[Act_of_Reparation]

32. Not much, actually.

There is a cosmological event horizon... the boundary beyond which light will never reach us because of the expanding universe. Right now, it's about 16 billion light years out.

[Sympthsical]

48. I might be wrong

Because trying to keep it straight is headache inducing. But my understanding is the cosmological horizon is at 45ish billion ly, meaning anything we observe now could be that far away at present. The event horizon means any light that leaves now that's 16 billion ly away or farther will never reach us due to expansion.

So all these things we'll observe when the universe was ~400,000 years old could be up to 45 billion ly away at present (13.6+ billion at the time).

At least, I think I'm understanding it right.

I very well could be wrong on it. When trying to understand the limits of the observable universe, I easily start getting things turned around in my noggin.

[doublethink]

63. Ha I know where you are ...

same as I. So the Universe is expanding, but expanding at a rate that our telescopes will never catch up with the outer edge of the event horizon, or the edge of our universe. We can't even with this Webb Tele and will not see the 'edge' of 'our' Universe ... ever?

Universe is what 13.what 8 billion years old and we can with the webb glance back 13 billion years? So close and yet so far. Last I checked before Webb we could reach out and see up to 40% of our known Universe. It's been awhile but the James Webb gets us a lot closer ... I'm blabbing now ha ... and ...


Just spewing things out in layman's terms. Watched a few videos from James Beacham the last few days. He works at the 'Cern particle accelerator' in Geneva, Switzerland. It's worth checking out some of his lectures, videos on youtube. Just type his name into the search engine at youtube and take your pick of what to watch, good stuff. Peace.

[Sympthsical]

66. I read astronomy textbooks for fun

And have a telescope in my yard (I really eventually want to get into astrophotography when time allows).

But when it comes to terms and articulating what is being discussed, the inside of my brain looks like that scene in Spaceballs where they try to grasp when things were filmed. So, "It was 13.7 billion ly away then, but it's 45 billion ly away now." And then my brain goes full this:

[Act_of_Reparation]

74. Ah, shit. You're right.

Except now I'm not sure how the distance of these objects is reported. If scientists are saying, "This Quasar is 13 billion light years away...", is that the actual distance at that location's present time or the observed distance from our perspective?

[Sympthsical]

24. Comparison to Hubble

[c-rational]

43. +1 Nice comparison- Thanks.

[doublethink]

52. Thank you for that. n.t.

[electric_blue68]

54. TY and I think I see more in the Webb photo

55. Thanks for that.

[Shanti Shanti Shanti]

31. Looks like the Hubble Deep Field, 4/6/8/13 billion who cares, I want to see Planets!

Turn the entire far side of the moon into a telescope, lets see solar systems.

[niyad]

39. Reminds me of the ending credits of "Men In Black".

[crickets]

40. So beautiful. nt

[c-rational]

44. WOW, Simply Wow!

[whopis01]

45. I was trying to figure out what this reminded me of.

Then it finally hit me.

[Pinback]

64. Now, THAT's the music they should've used

while we were waiting for the event to start today!

[Hiawatha Pete]

51. K&R for visibility

[getagrip_already]

53. If you look really closely....

You will see a 1968 Volkswagen beetle with an improbabilty drive signaling a left turn.........

[cloudbase]

56. How long before the fundies start

putting down critical space theory?

[Pinback]

65. DUzy!

… or claiming it was all created in the same studio where they filmed the fake moon landing?

57. All the way down almost in the bottom left of the picture....

If you look REAL hard, you can see Trump’s conscience.

Or maybe a cat sneezed on the camera.

[tavernier]

58. I love the spiral

on the right side of the picture.

[electric_blue68]

71. Zooms in. Look at that! Lovely! There's also a goldenish barred spiral towards the...

left corner that's pretty cool, as well.

67. What happens to black holes when they die?

What happens to black holes when they die?

They evaporate?

https://tinyurl.com/24emvvxj

[doublethink]

68. Nobody knows ...

maybe they just 'close up' and they were a former outlet to another universe. Like pluging a hole in a leaking tire for our universe to survive? Ha I have no clue. Some theories suggest we are all in a huge black hole presently ... how big who knows?

[Sympthsical]

73. They evaporate due to Hawking radiation

All very theoretical, but that's the current thought about them. I'm grossly oversimplifying the explanation, but paired particles around the event horizon pop up due to quantum fluctuations. One particle goes in, one particle is radiated out.

Of course, it would take a very, very, very, very, very . . . very long time for that to occur. 10^64 years for a black hole of the sun's mass to completely evaporate, and this assumes no more matter is going in during that time.

Mix in that supermassive black holes at the centers of galaxies can have billions of suns in mass . . . it would be a bit. Maybe order food first.

[SYFROYH]

69. My God, its full of stars.

[tavernier]

72. One of my earliest memories

is me floating toward earth, observing the planet as it came closer, and circling until I was about to land. I’m 75 so it wasn’t a memory or dream taken from a film or television show. Not many movies from space in 1946. But I’ve never forgotten it, and I’ve had a life long fascination with the universe ever since.
