[Technology] *** James Webb Space Telescope ***

[Hugo Rune]

The JWST has identified water vapour on another planet. Stunning. As we seek a new habitable home for Boris Johnson, this sort of data could be very useful!

Age of the universe is pretty much established as approximately 13.8 billion years old. James Webb telescope is reported as being able to see 13 billion years into the past. Wonder what James Webb 2.0 would see if it could see, say, 14 or 15 billion years into the past? Ulloa penalty maybe?

Too far gone for that, I'm afraid. With our current understanding, the furthest back we could see is about 370,000 years after the Big Bang, when recombination happened. Before then, the Universe was just a hot plasma that was opaque to EM radiation, so the mean free path between particles was so small, photons just couldn't escape. As a result of the recombination, we get the cosmic microwave background.

So where the bloody hell is Ulloa's penalty?!

Could we in theory see the big bang? If so, could we in theory see even further back than that? Or would that just cause the universe to implode?

They’ve not found that yet but have found this:

Not really, as there'd be no light to detect before that - there is a limit to what we could ever 'see'.

Cannot be long before they detect the oldest piece of Hiney Art in the galaxy

What if we took the photo with a flash?

Yet through all the technical innovation and lofty science, it still managed a cheeky selfie

Is it just me that thinks that the processing of this image had gone beyond what’s needed and dived into Walt Disney world. I’m sorry (and I know nothing) but I just don’t believe the “twinkle twinkle little star” thingy in the middle. Either the camera’s got some grease on it or someone’s got carried away with photoshop.

Although very impressive, I was disappointed when I learned that the colours are synthetic/artificial and that NASA add the colour for us using filters.

I have a recollection of Professor/D:Ream keyboard player Brian Cox saying that we can already see the big bang.

A podcast a while ago but i thought it was interesting.

The white noise on an old CRT TV is the background radiation left over from the Big Bang.

Hubble and the JW only record photos in b&w. The JW is only detecting infrared, so both sets of images have always been coloured by NASA but mostly done via the recorded wavelengths so not entirely artificial but definitely some creative licence involved. I’m not sure disappointed is the right word given the light we are seeing is billions of years old and shed much what is the human colour spectrum hence Hubble can’t see what the JW is seeing.

That's what you think.....
