Yes - apparently so.vanhees71 said:Amazing! Is this "glowing light" on bottom and top (the poles I guess) aurorae?
No I gave that a mental swerve.berkeman said:Did anybody else spend over 5 minutes trying to explain to their spouse why the Great Red Spot is white in this JWST picture?
"But it's not red! Why would it be called the Great Red Spot?!"

That Hubble Pallet can be an embarrassment at the same time as it's false colour reveals interesting features to 'experts'. I wonder if that's the problem.berkeman said:"But it's not red! Why would it be called the Great Red Spot?!"
Our Sun is classed as a Green Star; similar problem. The spectrum peaks in the greens but we call it White. It's all in the eye of the beholder.berkeman said:Did anybody else spend over 5 minutes trying to explain to their spouse why the Great Red Spot is white in this JWST picture?

Or just shifting the colour right with Webb. The shortest wavelength being blue and longest red.sophiecentaur said:Our Sun is classed as a Green Star; similar problem. The spectrum peaks in the greens but we call it White. It's all in the eye of the beholder.
By whom?sophiecentaur said:Our Sun is classed as a Green Star
You have a point there. There is a reference to the idea in a Wiki article that talks about the history of stellar classification. I'm being a bit sloppy about this but I'm basically saying that the perceived colour of a star is not a good form of classification because colour is completely subjective. Our colour vision attempts to make all illuminants appear as white and to give a consistent assessment of the colour of objects under a range of illuminants (fluorescent lamps completely defeat our colour sense)Vanadium 50 said:By whom?
Pallet -- a structure that is used to hold a heavy piece of equipment or building supplies. Pallets are often made of wood.sophiecentaur said:That Hubble Pallet
I may be able to put it all down to the automatic spell "correction". On balance, the app would have assumed that carrying things is more common than painting them. Embarrassing, nonetheless.Mark44 said:Pallet -- a structure that is used to hold a heavy piece of equipment or building supplies. Pallets are often made of wood.
Palette - a selection of colors.
Palate - the roof of the mouth or the sense of taste.
There is virtually nothing in the night sky (with the exception of the Moon) which we can see 'in colour' because our cone colour sensors are just not sensitive enough. We 'see' in almost monochrome, with just hints of colour in the most obvious objects. All those glamorous nebulae that we see in so many images on the net are the result of very long exposures on sensitive sensors, so it's all pretty artificial. Even the very bright nebula in Orion (stunning in its own way) appears as a bright fuzzy but colourless patch through my 10" reflector (a serious light bucket by amateur standards).pinball1970 said:What is there and what a human is able to detect and what these instruments illustrate is something that has been a real education for me.
