JWST images

[IB20]

Well here’s an “OK” TEST image…

If it doesn’t have spikes, it’s a galaxy 😃

[Craney]

Have they forgotten to take the Bahtinov mask off ??   We have all done it !!

but seriously.... are the spikes a result of the hexagonal cell structure of the mirrors ??

[Tomatobro]

Secondary support arms?

Mr Musk could tender for the job of sending a team out to remove it!

Now that would be a proper space mission!

With it supposedly reaching out past what the HST has viewed, was anything said about where and how distant this was?

Yeah… three support arms = 6 spikes

There are a fainter set of spikes offset from the brightest, wonder if the spacecraft rotated during exposure? 

[andrew s]

They could just be fainter spikes from the arms which are not normally visible. The full diffraction pattern is quite complex.  Regards Andrew

Just Awesome! Have the cores on those 20th mag stars (or whatever they are) burnt out the pixels on the sensor? Wow!

[Captain Scarlet]

The most prominent very strong 6 spikes surely are from all those hexagonal edges, 36 parallel edges contributing to each of the six spikes. I’d guess the support arms’ spikes will be a much fainter contribution.

Fantastic!... wonder if anyone out there are doing the same to us 🤔

often wondered the same. So long as they don't see us as a potential threat or future colony tho... 😉

I turned down the saturation to make it a simple B&W image.   It looks more like what we are used to seeing.

If the orange is one of the colors they are collecting it will be interesting to see what the JWST color pallet will be.

I believe the 'orange' colour is a NASA initiative to underwrite its not like Hubble. The JWST can observe over 0.6 to 28 microns, so definitely no orange there!

A NASA page that talks about the palettes for Hubble and JWST:

The first images are set to be released next Tuesday.....Looking forward to seeing what they pick as the first target.

Some lovely context at the power of JWST.

And that was made with the guide camera !!!!

 

[Alien 13]

The focus looks a bit off to me..

When NASA releases the first images on Tuesday, this and other JWST threads here on SGL (and other forums) for that matter are going to blow up, can’t wait to see that.

[Andrew G]

I think even as a test image that we know of it looks really really cool. The fact that it's going to be even better as well is even cooler.

[bomberbaz]

I think the galaxies in the background are all new discoveries, sure I read that somewhere.

Mostly they are way beyond our imaging capabilities but I am guessing someone is already trying to capture some of them.

They've just announced that Joe Biden will be unveiling one of the images this evening at 10pm BST.

It'll be on NASA TV channel and loads of other places as well I'm sure.
