That settles it.  Pluto is a planet!

They have added readouts for 5 more temperature sensors to the tracking page. All on the cold side.

That looks like a Mercury - Moon hybrid with too much make up on it to me,lol.

I've been seeing this picture floating around. Is this an actual photograph of Pluto from James Webb?
We're not getting any images from the Webb for five or six months yet.  It's a lovely Pluto mosaic, though.

JWST *has* had First Light, but only for alignment purposes.  The magnitude of the aligning process was described thusly: if the Webb compound mirror were the size of the continental United States, each segment would be the size of Texas, and at that scale would need to be aligned with an accuracy of 1.5" to each other.  The fine adjustments are really unspeakably fine (movements of a fraction of the wavelengths of light to be observed); it's expected to take three months.

And this is what HD84406 looks like to the NIRCam detectors before alignment. 18 different images of 1 star.

In addition to the alignment image, it's also taken a selfie

There's a three minute youtube on what they did there.

I hope it's galaxy photos are better than its selfie.  I'm not going to make to big an issue out of this because it was never designed for selfies.

The selfies are to allow the mirrors to be adjusted to their precise places. Still a work in progress.

SGOS

OK, that makes sense.  Is that why they have so many pictures of the same star in different positions?

Sixteen panels(#?) all have to be tweaked into the receptor. They didn't try to get them perfect BEFORE A VIOLENT SHAKING as they went out to L5ish.
