Happy birthday Hubble!
He's been out there for 25 years. That's pretty cool..

The HST has got to be the one piece of scientific equipment that had the most profound positive impact on the public's perception of space and science in general in those past 25 years.
And the best thing is that it has also done tremendously important science.

Quantum Physics: doing the same thing over and over again and expecting different results.

RE: Happy birthday Hubble!
college students today have always had Hubble photos. I remember when those pictures first started coming back and our minds were blown.

cant even imagine what the new James Webb telescope will 'see'

Infrared, mostly Big Grin
I wonder how they will process images for our public consumption. Will they shift the frequencies in the color images up to adjust for redshift to pull them again into the visible spectrum? Or will they simple put *some* color assignment that looks nice?

"The colors in Hubble images, which are assigned for various reasons, aren't always what we'd see if we were able to visit the imaged objects in a spacecraft. We often use color as a tool, whether it is to enhance an object's detail or to visualize what ordinarily could never be seen by the human eye."

James Webb photos will use the same techniques as Hubble photos, no doubt.

Give me your argument in the form of a published paper, and then we can start to talk.

Fantastic examples!

So, I was wondering whether they might, when they are looking at objects with large redshift, perform a kind of "shifted natural color" to recreate what we would see without redshift. For the representative or enhanced color images it doesn't matter so much.
