It's full of galaxies !  I don't think I have seen so much gravitational lensing in one single image before.  An amazing image for sure; can't wait to hear what the professionals can elicit from it.

Yes, I prefer that look to the oranges of the test images. It will be interesting to find out how they assigned the colour.

I expect it will be more impressive with a bit more scientific commentary.

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.

Only 12.5 hours? Imagine a week long integration...

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 covers a patch of sky 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.

This image is among the telescope’s first-full color images. The full suite will be released Tuesday, July 12, beginning at 10:30 a.m. EDT, during a live NASA TV broadcast. Learn more about how to watch.

Now that is impressive.

Zoom in, it’s just awesome!

Yes, on screen it looks under- well , not overwhelming, but take the full thing and look a bit deeper, you start to realise that there is real depth to the image.

They did a really poor job of showcasing this.

There's probably a lifetime's worth of research to be done just in that one image.

I'm at work so having to scroll round the image on my phone and I'm still dumbfounded.
