Gorgeous and upsetting that I'll never be able to visit it. 13 billion years before me, potentially trillions of years after me. Seems like such a waste of the spark of awareness that I can't take that awareness and experience the galaxy in all its glory.

I have reservations for the restaurant at the end of the universe.

There's a frood who really knows where his towel is.

> Of course there are other lifeforms out there, it's statistically implausible for it to be otherwise. I'll grant you that once we have found a single other planet with life. Until then we're doing statistics on a single data point and no, the number of planets and galaxies etc are not sufficient to statistically determine the prevalence of life because as yet none of them are confirmed to have life. This is wishful…

This is only true if we believe Earth is special, which we have no bases. So I'll stick to statistics for now, thank you very much.

Statistics is a very precise science. Can you show your work or is it just a gut feeling?

The youtube link to a 'zoom' in video to the image: https://www.youtube.com/watch?v=TkVprNB5XbI What is really, really neat to notice isn't just the detail in that final image.... look behind it, and there are whole edge-on spiral galaxies in the distance. Not stars. Galaxies. The nebula is about 1375 light years away. Those galaxies in the distance.... are billions of light years away. It's hard to comprehend.

There really is a lot of stuff left to see for the first time

"A lot" is the number of fish in a swarm maybe.

This is so far away from our concept of counting things that the mind just gives up. There's no comparison, no dumbing down to X amount of football fields, just nothing.

I find it depressing, confusing but also inspiring and fascinating at the same time.

I know nothing compared to people who work in the field, so I don't have my own work, I trust theirs.

How much of the pictures in the article are processed? What does the unprocessed photo look like?

All of the Webb observations are done in infrared light, which is invisible to us humans.

So the smartass answer is that it looks all black :)

Whose work exactly? I'm always eager to read about this fascinating question.

Isn't a nebula a cloud of dust? I'm not sure how dense it gets, but would someone even notice if they were inside of the nebula?

The zoom-in video at the end is utterly unbelievable, don't miss it. What an engineering and scientific triumph.

I wonder how fast an observer would need to be traveling for it to look like that!

99.x% the speed of light, but the image would be blueshifted and highly distorted.
