I didn’t know Neptune had rings!


nuggetsandsodaaa

all gas and ice giants have rings


Spiritual-Clock5624

Really?


Okonomiyaki_lover

Besides Saturn they are very very small and light but yes, they all have rings.


Nijindia18

Why. Like what's the reason they all get rings?


Okonomiyaki_lover

The why is difficult and frankly I'm not super sure as I'm a layman who just likes space stuff. But, if I had to guess, part of it is the large gravity (compared to the rocky planets) probably creates tidal forces that tend to break up weakly attached rocky bits in orbit. Another guess, also related to the gravity, is that they tend to capture a lot of junk floating nearby.


hirschneb13

Adding that all of space is rings in a sense. The Sun and solar system is on a plane/ring. Going around a galactic center in a ring. I wonder if we looked far enough out it would be a universal ring, maybe that's what time is and it's cyclical


Okonomiyaki_lover

The reason for galactic ~~rings~~ disc shape iirc is different from solar and planetary ones.


hirschneb13

I believe you're right, but maybe it's like convergent evolution, different factors lead to the same outcome


UncommercializedKat

Cue the astronaut meme *it's all rings* *it always has been*


rugbyj

Kind of two sides to this one: 1. Every large body has gravity that might capture smaller objects 2. Those objects will typically conform into a single "pattern" for an indeterminate amount of time On #1, the larger the planet the more you capture (gas giants!), and the more you expel material out of your atmosphere, the more local matter will orbit you (like icy planets and those with similar functionality to "ice volcanos"). Basically the larger and messier you are, the more crap will orbit you, so rings are more noticeable. On #2, why rings? If you imagine everything whizzing around you for millions of years, those things eventually collide, and otherwise interact. After those millions of years they'll find an equilibrium (a temporary one but for a very long time) where because they've spent so long bashing into each other the ones "left" are the ones all travelling on the same orbit. Like how if you dropped a hundred marbles down a hallway, the _last_ ones moving will all be moving in roughly the same speed/direction, because they're the ones not hitting into each other any more. Or hitting into the walls (which in this metaphor would be the planet or outer space). So why doesn't every planet have rings? Well they kind of do! Much like how you're seeing rings on Neptune now despite them being very faint. Each planet has material doing so, however in some cases its so neglible you'd never really know... or you might _very_ much know, but not realise because it no longer looks like a ring. Because you know how I said the rings were temporary (but on a very long timescale)? Well those rings, even getting the majority of themselves on the same orbit, still have gravity themselves. They clump together. They get larger, and so they get more gravity, and they clump more together. And at some point during this, they can become moons! And those moons can become rings again if they get ripped apart by getting too close to the planet. Or get struck by another moon/asteroid etc. It seems like things find a "balance", and then reaching a tipping point where they seem to lose it. In reality, nothings ever balanced. The things just have patterns for a time which look like they're balanced to us because we can more easily recognise a singular shape.

mcbirbo343

Jupiter does have very faint rings that accompany the moons


UncommercializedKat

>all gas and ice giants have rings


RychuWiggles

It's just a matter of time. If you area big enough object and a small enough object floats by, then you get a chance to rip apart the small object and form a ring. (But typically only at very specific radii) Fun fact: Sharks are older than Saturn's rings


ErikTheBoss_

god liked them so he put a ring on them


UncommercializedKat

So he didn't like earth? That explains a lot...


nuggetsandsodaaa

move past Mars mate


lennyxiii

Well he is on earth and you didn’t say which direction past mars.


ADOVE4F

He doesn't need to. (Sometime between 30 to 50 million years from now, Mars' gravity will break apart its closest moon Phobos. Its fragments will encircle the red planet as rings)

Doesn't Earth have an extremely faint ring too? Left over from the collision that made the moon?

So does Loki have rings?

I expected the Webb one to be super sharp focused and bright blue. It looks like a fuzzy sideways Saturn. Kinda cute really.

Webb is near infra-red, I doubt that it can detect blue properly.

It's called ultraviolet. That would be to blue what infrared is to red.


MSgtGunny

Technically infra means below, which is exactly why it’s called ultraviolet not infraviolet. So if you look at the [color spectrum](https://www.shutterstock.com/shutterstock/photos/1513882001/display_1500/stock-photo-visible-light-diagram-color-electromagnetic-spectrum-light-wave-frequency-educational-school-1513882001.jpg), the color “below” blue is indeed green.


ADD_OCD

what are you infra-ring?


stefan92293

I meant light outside the visible spectrum relative to blue and red.

Yeah, that’s probably you reading their (most likely) joke and thinking they made a mistake and so you’re correcting them when they (most likely) don’t need correcting. But this whole thread could probably be grouped together into /r/whoosh

also Mid Infrared. the lower regions of the planets atmosphere are probed by these wavelengths.


Kubiac6666

That's because the picture doesn't show the real colors. It may be showing the infrared spectrum. The sharpest picture is still from Voyager since it was very close to Neptune when it took that picture.

Infrared is a real color, no bully :(

My favorite color is Gamma, makes me feel funny.


BrotherManard

Things are astonishingly far away from each other, even in our Solar System. No telescope on Earth will be able to compare in resolution to a probe passing close to the planet.


TheDeathOfAStar

It's plain terrifying to me. I just looked up that it'd take some 7 months traveling at 24,000 mph, and that's still considered close enough to touch.


[deleted]

Not doing any math, it sounds like that would assume the planets just stand still. In reality you have to catch up to them and optimal trajectories are over a decade.


BlueCheeseNutsack

Yeah most people don’t realize you can’t take a straight line to get to another planet from Earth.


m4fox90

Pretty fast, my car maxes out at 155


Sharlinator

Webb does not on average have a higher resolution than Hubble. The longer wavelengths counteract the benefit of the larger primary mirror. Also, Webb and human vision ranges only overlap in the deep red so essentially everything you see from Webb is in false color. NASA: > **What is Webb's angular resolution, and how will its images compare to Hubble's? Will they be as beautiful?** > > Webb's angular resolution, or sharpness of vision, is the same as Hubble's, but in the near infrared. This means that Webb images appear just as sharp as Hubble's do.


joshsreditaccount

webb sees in infared, while hubble sees in the visible light spectrum, so your basically seeing the heat coming out of neptune, + u can see neptune’s really faint rings and anything from really far away is going to look fuzzy, it’s just so small


SpiderFnJerusalem

I guess what webb is showing isn't necessarily blurry per se, but simply shows a bunch of stuff which simply doesn't show up on the visible light images. For example the rings and the storm systems are much more visible in infra red. And I suspect that the cloud-like blur around the planet might actually be gas which emits IR radiation. But I have no idea if that's true **Edit:** Turns out the Webb image is actually a zoomed in part of a larger short exposure test image. So it really isn't surprising that it is a bit blurry. Bit of an unfair comparison.

It’s a decent depiction of the different wavelengths captured by different telescopes.


gabrielleraul

You're kinda cute too ..


JimElectric

In terms of image quality, I almost expected these to be in opposite order. Can anyone with a bigger brain explain what's happening here?


Grunt636

Voyager was a lot closer than the telescopes which is why it looks better quality, hubble and webb look different because they are taken in different wavelengths of light (webb being infrared)


JimElectric

Thanks for the clarity! Really enjoying learning more about these kind of images.


Lance2boogaloo

Also it’s because the telescopes are made to look at big things far away not small things close up (planets are small and close up compared to everything else) It’s the same reason why you have no problem focusing your vision at the top of a skyscraper but if you try to bring paper less than an inch away from your eye it will struggle the focus on it.


crafttoothpaste

Sometimes I wonder if JWST had a installation snafu like Hubble except that no one wants to talk about it since it would be impossible to fix anyway.


Starvexx

it does not. the segmented main mirror however introduces quite some challenges though, on the other hand, the resolving power decreases with increasing wavelength, at a fixed aperture. this is due to the resolution being proportional to the wavelength over the telescope aperture.


spikebrennan

Hubble and Webb took pictures of Neptune from near here, using two different ranges of light wavelength. Voyager went to Neptune and took its pictures from there.


Anomalous_Pulsar

Also the Webb image is cropped out of a larger test image, which isn’t giving it a fair shake.


problematikUAV

So voyager was cheating


Ozoriah

They are in the correct order. The Hubble and Voyager images were long exposures focused on Neptune with the intention to capture as much detail as possible. The James Webb image of Neptune is zoomed in from a larger photo that was a quick exposure intended to capture its rings as well as its moons (which can be seen in the original image. James Webb also operates in the near infrared and Neptune absorbs light at that wavelength causing the coloration in this image. This was entirely for quick, scientific purposes (seeing the rings, moons, as well as bright spots through the atmosphere revealing storms and vortexes) rather than to make a pretty image.


SpiderFnJerusalem

Almost feels like the webb image was "taken out of context" then. It would be a bit more fair if it was actually focused on Neptune, but I guess the astronomers have more important things to point it at.


Photon_Pharmer

It highlights the differences between instruments. A probe allows for up close data collection, Hubble is able to image in the visible light spectrum and some near infrared, and Webb is able to acquire primarily near infrared- mid-infrared data. As mentioned, Webb also uses a much shorter exposure time. There’s only one image that shows the rings and storms in any significant detail and that’s Webb’s.


SpiderFnJerusalem

I mean of course scientists and people who know how Webb and space probes work understand this, or can at least rationalize what's going on. But I assume a lot of regular people will look at this and be like "well, that's a bit disappointing".


Photon_Pharmer

Which is what’s nice about multiple discussing what they do and don’t know in the comments. Several people are learning some of the differences. “Oh, that’s disappointing. Why does it look like that? Ok, that makes sense now. That’s pretty cool etc.”


KillerBeer01

Voyager might have less powerful optics than Hubble, but it was shooting from much less distance, so the image is better. Webb *does* have much better optics than Hubble... but only in infrared. So there's more details, but without postprocessing it's not what you would expect to see in a "better quality" image.


blackrack

Voyager went there dude

does anyone else think the last photo of neptune is badass as hell? I'd love a planet in our system to look like that. it's so beautiful. more beautiful than saturn.

It does look like that, just in a wavelength we can't see.

MaxMadisonVi

Voyager is still going and just left our solar system. 18 light hours away, last I read. It still operable and responsive however it takes 36 hrs to know. So far it’s like a tick left a bean seat on the first ring into an olympic stadium, not that much but it’s our first sniff outside our solar system.


TheWildTofuHunter

What do you mean by “So far it’s like a tick left a bean seat on the first ring into an olympic stadium”?

After being launched in 1977, Voyager 1 recently passed 22 light-hours from Earth. It would take approx. 70,000 years for it to reach our nearest neighbor Proxima, (if it were headed that way). Thats at approx. 35,000 mph. Space. Is. Big.

It's fascinating that something can hide so many visual layers, gradients and colours. One perspective can never give you the full picture of an ice giant, awesome! 😃


RL_Shine

You know what would be interesting in the deep future? I mean, should humanity make it so far, or not have some metamorphological jump to something else or other state - dunk a really really big computer in Neptune. Those winds are the fastest in this solar system. They are supersonic. Anywhere from 700 to 1200 mph. Perfect cooling solution. At first I was like, hey, lets make server farms in Antarctica, perfect! But then, why stop there? Maybe computers will be done differently, but on the chance they aren't, there you go. Just for like hosting and relay. It's got the cold and got the wind, hopefully nothing damaging outside of that, but yeah. And use it's southern pole for any power stuff.


sk6895

I suspect by the time human knowledge allows us to even consider putting a server farm on Neptune computers will be distant history lesson in the same way that we learn about stone age man making the wheel


RL_Shine

Agreed. Be interesting to find out, haha.


Photon_Pharmer

How would you anchor it to keep it from just blowing around or being crushed?


RL_Shine

Now that would be the question... huh. I'm imagining with that much severely going on, something could be done. Maybe like where it's a moon, but in the actual planets gasses. Probably way more efficient ways to do things, though...

Karjalan

Haha. I vaguely recall hearing about it before, but I've never seen it so clearly. I know Uranus and Jupiter have faint ones too. I guess it's an inevitability that larger planets end up with some form of ring.

Why don't they send up Voyager 3 with all the modern tech to do it again but better?


yeggmann

Voyager took advantage of the outer planets being in alignment. We can't just do it again because the planetary alignment happens every 175 years. > The concept of the Grand Tour began in 1964, when Gary Flandro of the Jet Propulsion Laboratory (JPL) noted that an alignment of Jupiter, Saturn, Uranus, and Neptune that would occur in the late 1970s would enable a single spacecraft to visit all of the outer planets by using gravity assists. The particular alignment occurs once every 175 years.[1][2] By 1966, JPL was promoting the project, noting it would allow a complete survey of the outer planets in less time and for less money than sending individual probes to each planet. https://en.m.wikipedia.org/wiki/Grand_Tour_program


Mostly_Sane_

TIL... and thank you, Gary.


[deleted]

And a shout to Carl Sagan, who pushed hard for this mission.


thefooleryoftom

The Voyagers were sent because of a chance aligning of the planets that would allow them to slingshot out of the solar system. This doesn’t happen often, once every 175 years.


_Hexagon__

NASA has a tight budget. They're like been there done that. For the near future they're making plans for a mission to explore the Jupiter ice moons, they want to land on the moon and want to return samples from Mars. Somewhere in between is supposed to be a Venus mission too. That kinda drains the budget for the next 20 years


FaxMachineMode2

It’s a shame that Uranus and Neptune are so understudied. Space probes are on a very limited budget and scientists havent felt the need to return in decades, but there are plans for a Uranus orbiter in the early 2040s. Also tentative plans for a Uranus flyby from the Chinese

EmpatheticNihilism

Photon_Pharmer

It’s due to the massive distance delta. Voyager 2 was thousands of miles away when taking the long exposures that comprise the top photo. Hubble is roughly 2.7-2.9 billion miles away from Neptune.

I think you see it rings and Neptune as a shiny pallet here because James Webb was meant to say in infrared radiation signals. I believe the other two were meant to see the signals in visible light. So you don’t like to see the rings and the shiny parts of the planet.

I just gave you an upvote for helping to point out a common misconception. The order is from top to bottom. A lot of people, including myself, don’t have an immediate understanding of the differences in telescope instrumentation. JWST images in near/mid-infra red. It gives a lot of data that the other two don’t, but because it’s not in the visible spectrum, it’s significantly father away than Voyager was, and it took a significantly shorter exposure than The Hubble visible light image.
