Where Is Webb? NASA/Webb
'WhereIsWebb' tracks the status of Webb on its journey to L2 orbit and through its deployment and commissioning process leading up to the release of its first images. The page constantly updates as Webb travels, deploys, cools to operating temperature and as instruments are turned on, tested and...

James Webb's First Pictures are Out! But it's a Work in Progress
Scientists from the James Webb Space Telescope shared the first images from space taken by the new telescope. Since the 18-segment mirror is in the early stages of being aligned, the first image is understandably blurry and a bit jumbled. But its exactly what the team wanted to see. “The initial...

The big dots are all supposed to be the same star aren't they? An alignment guide of sorts?
Unbelievable the precision they need to align those mirrors to. Let's hope they did not fuck it up, like Hubble way back when it was launched first

Yes it is the same star. The light from the star hits each of the 18 mirrors and is reflected on the camera that looks at them. We see 18 different pictures of the star from a tiny different angle . They will be aligned to send the light at the center of the camera creating one "3D" picture . These tiny different angles will probably help the computers "understand" the depth and simulate the 3d model. It really needs unbelievable precision (probably movements of nm or μm and 0.00...01 angles) but I think it is much easier today than back then. I am positive they will make it
That's a great explanation

Should’ve gone to Spacesavers
It's not ready yet to get to work though https://www.space.com/james-webb-space-telescope-instrument-alignment-begins
NASA scientists say images from the Webb telescope nearly brought them to tears
Deep field images of the universe, exoplanet atmospheres, and more to be unveiled.
"NASA said it plans to release several images beginning at 10:30 am ET (14:30 UTC) on July 12, the result of Webb's "first light" observations. On Wednesday, space agency officials said the images and other data would include the deepest-field image of the universe ever taken—looking further into the cosmos than humans ever have before—as well as the spectrum of an atmosphere around an exoplanet. By looking in the infrared, Webb will be able to identify the fingerprints of small molecules, such as carbon dioxide and ozone, that will offer meaningful clues about the habitability of worlds around other stars.
NASA's deputy administrator, Pam Melroy, said she was blown away by the images Webb has produced so far. "What I have seen moved me, as a scientist, as an engineer, and as a human being," she said."
Sounds interesting

First Images from the James Webb Space Telescope
The dawn of a new era in astronomy has begun as the world gets its first look at the full capabilities of NASA’s James Webb Space Telescope, a partnership with ESA (European Space Agency) and CSA (Canadian Space Agency).
I wonder on those pictures where they get the colours from. An infrared image obviously has no colours we can see.
