Right click on image and select "view image" for full size.

Nice video that explains the image, too.

I could not find the video on their site.

Not related at all.

It’s an embedded video about half way down the page. It might just look like a black picture. It’s there - it shows how the picture was created.

Space and stuff ping

Thanks for the reply but I still could not find the video. I clicked on both photos without success.

Less spectacular but perhaps more intriguing is the mottled backdrop at the top and bottom.

Even more intriguing to me is the dark area outside the oval. As I have always wondered, since hearing about it in the 8th grade, if the universe is expanding, into what exactly is it expanding?

Did you see the video on how the picture was generated? The picture shows a composite of pics taken at the center of sphere. As if you could put a rotating, spinning camera in the inside of a beach ball and have it take pictures of the inside of the ball. Then open the sphere to show the shape you see.

It's not that the satellite has left the Universe, turned around and took the picture.

THX for the ping.

What are your reactions to this?

It's not that the satellite has left the Universe, turned around and took the picture.

I completely understand that. By definition the satellite could not leave the universe and turn around for a snap. The oval-shaped sphere obviously represents the limited area from which the satellite can gather light (in a given period of time).

However, the question of what the universe is expanding into is still reasonable.

What, ya mean I have to *read* everything before I ping it? Just wow. ;')

Immediately striking are the streamers of cold dust reaching above and below the Milky Way. This galactic web is where new stars are being formed...

IOW, we live in a swarm of crud.

Less spectacular but perhaps more intriguing is the mottled backdrop at the top and bottom. This is the 'cosmic microwave background radiation' (CMBR). It is the oldest light in the Universe, the remains of the fireball out of which our Universe sprang into existence 13.7 billion years ago.

Hey, at least they put it in quotes. When I was a kid, it seemed as if every couple of years someone on grant money pointed a radiotelescope in several directions over the course of a few observation seasons and discovered CMBR.

Sorry, at first I thought that's what it was but quickly realized that that was impossible. I mistakenly thought you had, too.

I agree. It does beg questions and, to me, incomprehensible dimensions.

I thought you’d have an interesting response.

which, being translated means, it was &

thanks.

-- if the universe is expanding, into what exactly is it expanding? --

It boggles the mind, but there isn't even a nothingness outside the universe. Space itself is supposed to be self-contained, and limited. Sort of like the earth, limited area, but no edge to fall off of. Space, limited volume, but no "edge" to nothingness.
