Simply AMAZING!!!!!

[mad_as_he$$]

Thanks again for your work.

So many responses and so little time.

LOL.

I remember decades ago, Uranus was pronounced as if people were saying “your anus”. Apparently due to the dirty jokes provoked, nowadays most people pronounce it similar to “your in us”.

But couldn’t that sound like “urine-us”, and similarly provoke dirty jokes????

They mention that the rings are about 1 million times fainter than the planet. The pixels are sampled by analog-to-digital converters (ADC) to digitize the data for each pixel. A 16-bit ADC only has a full resolution of 65,536. For a resolution of one million they would need a minimum of a 20-bit ADC. I know that there are 16-bit, space qualified ADCs. And 20-bits is absolute minimum because you need headroom above max signal level so they would probably need 24-bits. And I don’t know if there are even non-space 20-bit ADCs. That is why I thought they had to be using a dynamic range compression scheme like what I mentioned before. It is probably why old images don’t show the rings.

True so I wonder what the halo type thing is? Maybe just a photo artifact.

[MtnClimber]

I did a web search and did find 20-bit and 24-bit ADCs, but the sample rate is really slow. Much to slow to handle a large CCD array that would take these images.

When it comes to “Gas” giant planets. Just how much of them are gas and what kind?

[wardaddy]

It’s a gas gas gas gas

And a Storm bigger than the earth spiraling merrily away.

What is is with the ‘spikes’ around brighter dots?

They are also around the planet too, looking like clouds north and south of the planet.

Were those expected?

Can they be filtered out?

For a loooooong time.

Galileo first noticed in his ‘new’ telescope.............

[Red Badger]

Mainly HYDROGEN, HELIUM, METHANE, AMMONIA and WATER VAPOR..........................

Except that “surface” is just the denser part of the atmosphere. The real surface is probably quite a few miles below that.

Actually that is what I thought.I always wondered if Jupiter could be ignited and become a dwarf star.

[Red Badger]

Jupiter would need much more mass to become a star.........................

Yeah, right ...not sure what the whole hubbub is about, frankly. Kind of a cool image, but beyond that, 🤨🧐
