Slightly adjusted desktop background

Slightly adjusted desktop background of initial image. Jupiter over star field.

Jokes aside, damn thatssa a pretty planet

"girls go to college to get more knowledge, boys go to Jupiter to get more stupider"

Kids say this to each other

[-] BeatTakeshi@lemmy.world 11 points 3 weeks ago

Thanks ! Never heard it before

[-] 13igTyme@lemmy.world 9 points 3 weeks ago

Some of us went to Mars, to get candy bars.

And I went to Venus, to get more...

[-] Hadriscus@jlai.lu 4 points 3 weeks ago

fabulous !! you got more fabulous

[-] AlteredEgo@lemmy.ml 2 points 3 weeks ago

Thanks. The rhyme doesn't really make sense though, right? Or am I missing something?

[-] sem 1 points 2 weeks ago

It's not based in logic, unfortunately.

Isn't that artificially colored?

[-] Zetta@mander.xyz 29 points 3 weeks ago* (last edited 3 weeks ago)

Ya, but I rather think about it as an 'enhanced spectrum' image. The structures you see are all real and similarly coloured, it's just enhanced

[-] FinalRemix@lemmy.world 15 points 3 weeks ago

Ahh, yes. Crank the saturation, crush the shadows, and blast the highlights.

[-] rockerface@lemmy.cafe 25 points 3 weeks ago

Almost all gas giant images are

[-] ChaoticNeutralCzech@feddit.org 5 points 3 weeks ago

The famous Jupiter one isn't.

[-] WhiskyTangoFoxtrot@lemmy.world 4 points 3 weeks ago

Yeah. Neptune's a dull grey.

[-] lemming@sh.itjust.works 5 points 3 weeks ago

Not quite. It's based on real wavelenths detected, but they might've been arificially assigned colours (although I think the images this is based on sort of correspond to human perception). But the colours are massively adjusted and contrast increased way past the point I would consider reasonable.

[-] brbposting@sh.itjust.works 2 points 3 weeks ago

These images are mindblowing. Bring me back down to Earth? Do you have a favorite image with reasonable coloring and contrast?

[-] Quadhammer@lemmy.world 12 points 3 weeks ago

Mmnm I bet there's chocolate nugat and bipedal organisms in there

[-] Whats_your_reasoning@lemmy.world 16 points 3 weeks ago* (last edited 3 weeks ago)

This is a really good question. I suspect the color in the image has been enhanced. I've been trying to find a scientific reason that the clouds could appear blue, but haven't found anything conclusive.

However, I did find a NASA page with raw images of Jupiter.

Here's a raw image:

Here's an image that's been color-enhanced:

It's not uncommon for space images to be color-enhanced. On the one hand, it may feel less authentic. On the other hand, the visible light levels in space may be insufficient for our expectations and uses anyway. Although I don't know the origin of the picture at the top of this page, I know that it's common practice for space photos to be enhanced. In fact they're often taken in non-visible spectrums and fully converted to something humans can see and comprehend. Ever see detailed, colorful photos of galaxies? They were probably taken in X-ray and colorized in processing. Cool as it would be, you wouldn't see those colors in real life.

[-] brucethemoose@lemmy.world 6 points 3 weeks ago* (last edited 3 weeks ago)

The junocam page has raw shots from the actual device: https://www.msss.com/all_projects/junocam.php

Caption of another:

Multiple images taken with the JunoCam instrument on three separate orbits were combined to show all areas in daylight, enhanced color, and stereographic projection.

In other words, the images you see are heavily processed composites...

Dare I say, "AI enhanced," as they sometimes do use ML algorithms for astronomy. Though ones designed for scientific usefulness, of course, and mostly for pattern identification in bulk data AFAIK.

It's not uncommon for space images to be color-enhanced. On the one hand, it may feel less authentic. On the other hand, the visible light levels in space may be insufficient for our expectations and uses anyway.

Another thing to consider is that human perception of color in celestial objects is often just wrong, so enhancing the color of certain objects is more true than what we often see ourselves.

The sun is the same color all the time: white, consisting of a broad spectrum of all the wavelengths in the visible light range. But our atmosphere scatters the different wavelengths differently, so we see a blue sky and we see yellow, orange, and red sunsets. The atmospheric effects are happening all the time, with all the other light that happens to hit our planet, like the moon seeming to change color while reflecting the same white sunlight.

The stars in the sky are all sorts of different colors, but appear white to us, because our color-blind rods are much more sensitive than our color-sensitive cones, and the dimness of starlight just all looks like faint white lights regardless of whether the star happens to be red, yellow, blue, or white.

Meanwhile, relativistic effects might actually shift wavelengths and resolution, too, whether we're talking about redshift or gravitational lensing, and asking what the "true" image is supposed to be.

So when we take a long exposure of something in space, that itself may represent something that the human eye can't see. Using colors to represent the different wavelengths actually present may also require adjustment of what physical filters are used on the capture, and how the actual sensor is configured to account for different wavelengths (including potentially wavelengths not within the visible spectrum), and to account for literal noise captured by the sensor.

Astrophotography needs to make choices about how to translate sensor data to an actual human-visible image displayed on a screen with its own limited color space of what its pixels can display, or printed on paper with its own limited color space of what inks are available for printing.

[-] ClanOfTheOcho@lemmy.world 2 points 3 weeks ago

I believe the image is from one of the poles, rather than the side view we usually see.

There are jet winds circling around Jupiter westwards and ones that are circling the other way, which creates turbulence, and there are ginormous thunderstorms as well

[-] Tollana1234567@lemmy.today 4 points 3 weeks ago

the storms, and different chemical/compositions im guessing.

I don't get it, do you mind explaining?

[-] kshade@lemmy.world 37 points 3 weeks ago* (last edited 3 weeks ago)

It's a thing kids say to taunt each other, "girls go to college to get more knowledge, boys go to Jupiter, to get more stupider".

[-] ChaoticNeutralCzech@feddit.org 24 points 3 weeks ago

...or vice versa, usually depending on the taunter's gender.

Also, see xkcd 1202 and 2771

[-] Viking_Hippie@lemmy.dbzer0.com 4 points 3 weeks ago

Now I've got a hankering for pamplemousse ๐Ÿ˜„

[-] neukenindekeuken@sh.itjust.works 6 points 3 weeks ago

Ah, got it, thank you!

[-] grrgyle@slrpnk.net 3 points 3 weeks ago

What does that... mean? Is it a jab about college attendance demographics skewing towards women?

[-] __Lost__@lemmy.dbzer0.com 9 points 3 weeks ago

Kids don't know about college demographics. It's a dumb thing kids say to tease each other. Like 7 year old kids. It just means boys are stupid.

[-] grrgyle@slrpnk.net 3 points 3 weeks ago* (last edited 3 weeks ago)

Yeah one of the ~~Moody blues~~ someone posted with the girls playing jump rope made it click

EDIT oops I meant "comic." I got distracted by the Moody Blues playing on the radio.

[-] Wolf@lemmy.today 2 points 3 weeks ago

The thought of elementary school girls clowning on boys by pointing out college attendance demographics is precious though.

[-] exasperation@lemmy.dbzer0.com 2 points 3 weeks ago* (last edited 3 weeks ago)

From what I remember, the taunt predates women overtaking men in college completion (which happened in approximately 1995). It's pretty old at this point.

Here's a newspaper article mentioning it from 1993:

[-] AngryCommieKender@lemmy.world 8 points 3 weeks ago

That looks like a lot of storms

Sexyy photo

I'm no scientist, butt I believe that is an image of Jupiter's Uranus

[-] Obi@sopuli.xyz 2 points 3 weeks ago

I want to hang a picture of it in my house so when guests compliment me on it I can say "Oh you like it? Me too. It's a picture of Uranus"

[-] melsaskca@lemmy.ca 2 points 3 weeks ago

It used to be called Christianpiter.
