This. I used to take a very active interest, but found the more I learned, the more it depressed me. Just more unanswered questions, and places we will never visit.

Hubble Vs JW

Bit sceptical about that one, source unknown. Thought the point was Hubble couldn't work in the infrared to see back that long ago. I think those images are someone doing an illustration rather than reality.

My brain exploded on trying to comprehend the scale of what I'm looking at.
Fantastic image.

The universe is full of life. It has many intelligent civilisations.
Or it doesn’t. There’s nothing else anywhere.

Either answer is irrelevant.

A great comparison with Hubble of the same spot

Ah ok, could well be. It does seem a rather 'exact' comparison.

There’s between 100 billion and 400 billion stars in our galaxy alone.

There's about 100B neurons in the human brain, [each with 15K connections], so about as many stars [lower limit] as in the galaxy. It's like the galaxy shrunk into your head.

Hows about them onions eh?

The fractal nature of the universe. The same patterns repeated ad infinitum.

[Roofless Toothless]

Would it be possible to repeat the Hubble Deep Field experiment with this new telescope and similarly rack up by a few notches our estimations of the number of galaxies out there?

Thanks for linking.

That is.....superb! And humbling....

Was there a particular reason for pointing it at that particular spot of the universe?

I think with the Hubble they deliberately picked an apparently empty patch of sky.

I liked the quote from the live feed, along the lines of "Hubble took two weeks for the deep field image, we took this photo before breakfast".

Nice try NASA




(I totally stole that)

[Pilotguy]

The Super Telescope documentary on BBC 2 is excellent.

If they pint either Hubble or the JWST anywhere else, do they see a similar field of ancient galaxies ?

Or have they deliberately looked towards the original location of the big bang (how would they know that anayway) ?

Scott Manley has posted his explanation of the pictures on YouTube. Highly recommend as always

There is no "original location". No matter what direction you look, you will be looking back at the origin of the universe. However, that does not mean that you can look in any old to see this evidence.

In most directions you look, your view is blocked by stars, galaxies, dust and gas which are all much closer to us. In order to be able to see back to REALLY old stuff, you need to explore through gaps in the closer material. It's a bit like trying took at distant hills when you are in the middle of a forest. In some places, the trees in your way will thin out and that is where you should point your binoculars to get a better look at the distant hills.
