Pretty amazing. From what I can gather that's 1/32 millionth of the sky.


Also interesting is the Hubble Ultra Deep Field (2003):

It looks like a blurrier, grainier version of ultra deep field.

That constellation near the top that looks like it has two eyes... I doubt they've named it yet. I hereby name it Constellation DrPizza.

Two crossed eyes



Its already been named the Vienna constellation by Joe Mchale

 

[clamum]

Cool shit for sure.

i can see my house!

This is the same pic as from 2009 but just enhanced? I don't get what they did because I agree it looks grainier.

Anyway...this pic always blew my away. Looking at it makes me think if we truly are alone in all this....scratches head...then wtf?

Well it essentially is. The UDF was done over the course of a year or so. This one is an aggregate of 10 years of images

Those photons are like, old.

i think this kind of stuff proves we arent alone. i think mathematically it would work out to near 0% chance that we are the only ones here. the universe is bigger then all of our imaginations combined times a few thousand trillion. its just insane how big it is.

 

[Jeff7]

The XDF is a small fraction of the angular diameter of the full Moon.

Ah. Excellent. That's very specific. :\



Edit: Here we go:
"The image is 2.3 arcminutes by 2 arcminutes in size."

Google says....the full Moon appears a little over 30 arcminutes.

And a helpful link.

We're not alone. That line of thinking was propagated by people without access to the knowledge that we have now of the world. Why people still take stock in such outdated wonderings is confusing to me.

:thumbsup: Very cool!

what's with the new picture, pinky?

Actually, it doesn't. Those galaxies looked like that 12 or 13 billion years ago. The majority of stars back then would have been first generation stars. It isn't until after stars go supernova that we have elements such as what's found on Earth to actually make a solid planet. That is, most of those stars would not have planets around them at all, let alone have planets that could support life.

Of course, we do know that stars go boom, and from that material, we end up with new stars that have planets around them. That picture, nonetheless, provides zero proof that this happens.

13.2 billion like years old

13.2 billion like years old

Depends on the perspective. To the photons themselves, they are not nearly that age.

Actually no. Those are mostly going to be 2nd gen stars. First gen stars were very short-lived, and we may never see one.

Wikipedia says the James Webb telescope won't be ready until at least 2018.

it's beautiful.

http://en.wikipedia.org/wiki/Chronology_of_the_universe#Structure_formation

the universe is 13.7 billion years old
these stars are seen as they were 13.2 billion years ago
the first stars formed 150 million to 1 billion years after the big bizang

The youngest galaxy found in the XDF existed just 450 million years after the Big Bang.

As I sit here in my plain ranch home, I realize my plain home is part of a beautiful universe that is beyond comprehension.

That will be so exciting!

 

[mizzou]

Soooo...if you magnify to a certain extend...you should see what happened before the big bang?


The way I've always pictured FTL travel is, like you are watching a football game and you see your team about the score a touch down. On some TV channels, the play is already in progress, when you are seeing a more delayed broadcast. But if you instantly traveled to the football field, you would probably watch your team already celebrating the touchdown.

So what we see isn't what is actually existing, it's just a ghost or transmission of what happened.

It's also why I don't understand how FTL travel will also enable time travel.
