Absolutely wild that we're looking at a picture of galaxies we haven't seen before. Like aren't we talking about trillions upon trillions of stars that we're seeing for the first time in that picture?

Watching the universe form in the details of gravity lensing.

Infinite space & infinite stars showing fine details in curves of light.

Here's where you can view all the full-res pics as they're posted tomorrow https://webbtelescope.org/news/first-images
Here's the full res PNG of today's photo, 4537x4630, 28.51MB. It's maddeningly beautiful.

NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail.
Thousands of galaxies – including the faintest objects ever observed in the infrared – have appeared in Webb’s view for the first time. This slice of the vast universe is approximately the size of a grain of sand held at arm’s length by someone on the ground.
This deep field, taken by Webb’s Near-Infrared Camera (NIRCam), is a composite made from images at different wavelengths, totaling 12.5 hours – achieving depths at infrared wavelengths beyond the Hubble Space Telescope’s deepest fields, which took weeks.
The image shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago. The combined mass of this galaxy cluster acts as a gravitational lens, magnifying much more distant galaxies behind it. Webb’s NIRCam has brought those distant galaxies into sharp focus – they have tiny, faint structures that have never been seen before, including star clusters and diffuse features. Researchers will soon begin to learn more about the galaxies’ masses, ages, histories, and compositions, as Webb seeks the earliest galaxies in the universe.

Many “Whelps”! Handle It!
I thought there was a problem with the stream I was watching. Turns out it ended like the final episode of The Sopranos.

Can they zoom in on actual planets with these telescopes?

As in see skyscrapers of an alien world? No

It'll detect the materials that make that planet via emited wavelengths when it passes over a sun and it can be a solid lead to find life forms that would emit non natural gas. But not like details of the planet, they don't or barely emit light.
 
Hundreds/thousands of galaxies in a view of space roughly the size of a grain of rice held at arm's length and people complain 🤣

Can't wait for all the images tomorrow and the years beyond.

Been looking at that for 20 minutes.

Text says it all though. JWST did this in 12,5 hours where Hubble needed Weeks and still couldn't observe certain wavelengths. (One could argue that JWST is about 30times better at least then Hubble)

JWST work is just beginning, I'll be glad to see more of its work in the future.

I was right. Stars behind stars. Galaxies behind galaxies. It's a huge step up for science and discoveries for detail but come on if the marketing department didn't fuck up by not going for one close up object for that wow factor on the first image. I wonder when they'll release a pic of a real focal point object?
 
Damn, why didn't I buy Mass Effect Remastered during the sale?

But they can't zoom in on planets that are far closer?

It can be pointed at basically anything in the sky. Just needs some brightness protection for nearby objects like Mars. It will be used to study planets in our system.

Regarding exoplanets:
John Grunsfeld: James Webb is sold as studying galaxies, but I think its greatest discovery may be a habitable Earth-like exoplanet. That's what's going to blow everybody away.

Mullen: So you'd be able to directly image a terrestrial planet, which has never been done before?

Grunsfeld:
Exactly. But it wouldn't be like a Rand McNally map, it would be a spot. But because you'd see a spot, we can then do a spectrum of that spot.

Mountain: You'd actually get a color. If it's like Earth, it'll look blue.

Grunsfeld: And, if you had enough time, and there were seasons, with ice covering and then going away, you could study it and be able to tell the difference between winter and summer on the planet, or vegetation, in principle. Just from unresolved single pixels, because of the color changes.

Mountain: Or you could tell it is rotating.

Mullen: Is there a limit to the kinds of stars JWST can target for planet searches?

Mountain:
You can only look at stars out to a certain distance, to about 10 or 20 parsecs. But that's ok, because the planets [farther out] are too faint anyway. Any farther away and we can't differentiate them, both the planet and the star will be hidden by the star shade.

It can also detect signatures of industry and industrial farming.

There are billions of targets but only a decade's worth of fuel.

But what if they left Webb's shutters open for a few weeks like they did with Hubble.

I bet we will see some shit with a Webb Ultra Deep Field.
 
And we probably will. Though I wouldn't expect it to soon. As for now scientists/teams from all over the world are fighting to get time for even small projects/shots.
There's a mom/daughter exoplanet hunter team looking to get time on Webb to study a few exoplanets. I'm looking forward to what they find.

I pray to god they have a crack at Trappist 1 system of exoplanets.
