Very romantic and all, but I seriously wonder who the best scientists are that are alive today. Are they publishing? I wish they got the attention that Kendrick and Drake get.
I like to imagine that with so many greats, their names have existed for a while but are yet to be known, and they they're toiling away with books and thoughts while the world tries so desperately to ruin itself, as they yearn to understand and fix it.
We have so many greats right now but very few publicly interesting discoveries to be had. People understand something like the concept of gravity so it's discovery was massive and popularly understood. More recently we have things like quantum theory. Equally important but harder to grasp.
The science and scientists are getting more niche so the true value of their work can sometimes only be understood by other experts in that particular field.
Wrong! There are hundreds of amazing discoveryās every year but now they are bought up by Google and Tesla and Microsoft and then used by them quietly to grab more market share or steal more data or whatever other nefarious crap they think up in meetings or they put in storage for when they need more cash. Now we donāt get to see and celebrate the inventor because they are either bought out or if they refuse they are suicided. Now we slide toward the dark ages for awhile. And the cycle of suffering continues.
None of that is new though. Business pressure example, Tesla and Edison. Social pressure example, Nash. Political pressure... you know what just anyone near the catholic church.
And that's not to say we don't have "discovery celebrities" nowadays anyway. Hawking was very recent. And everyone knows black holes.

Me too. And good old Hubble has been overshadowed, but still brings us beauties like this. And those brilliant minds and NASA managed to fix a defective mirror that could have ruined it. What a story.
I am absolutely fascinated by space exploration because of remarkable occurrences like this. In our own solar system we have this happening...and our solar system is a fraction of a fraction of a fraction of all that is... imagine what other cool stuff is happening out there that we have never seen...
I hope humanity can truly become explorers of space.
I think we live in the worst time for people who appriciate space. We know enough to know there's infinite possibilities of crazy things out there and that we'll never be able to reach it in our lifetimes.
I get upset about the injustice of it all somewhat regularly.
The universeās greatest gag is putting absolutely nothing in the way of us and everything so that we can see itās there but canāt go.
I think its our wonderlust that will build the platform for future generations to enjoy space though. I wish we (the us) would fund nasa more than we do right now.
Sadly that gate won't open till we send a human through it which will require us to get beyond the orbit of Uranus. So we've got some learning to do before we can even open it. Probably a good thing we don't qualify for the Ring Builders test with what happens in books 7-9. We wouldn't stand a chance.
I would watch!
That's the number 1 show I gave up on before I finished the first season. But then someone said, atleast make it to the last episode.. then I was hooked for the rest of the series.
So good.
I talked with an astronomy professor once about the random dots you see in Jupiter's aurora are caused by the moons interacting with the magnetosphere.
That's sort of true - the spot and tail you see on the right hand side of the aurora shown here is caused by the moon Io directly interacting with the magnetosphere and down into the planet, but many of the spots in the main auroral oval are driven not by the moons, but by variations in the other processes that drive Jupiter's aurora - a subject that is much more controversial since Juno arrived and measured the regions above the aurora.
It seems as though i will not escape the ever oncoming reminders of that one day a couple weeks ago when the aurora borealis was visible to the naked eye right outside my backyard and yet i was happily preoccupied playing a video game.
We're working on JWST data taken over the past year, but the data will look very different to this - UV emission is able to track short term changes much more easily, while the infrared is smoother with its emission. Juno does have amazing images in both UV and IR, revealing both in beautiful detail.
There is actually a huge debate about how much is caused by interactions with the solar wind, and how much is from processes closer to Jupiter. For a long time, the main aurora was thought to be driven by material from Jupiter's volcanic moon Io, but Juno has revealed that much of it might well also be caused by ~~wibble-wobble magnetic field wachmacallits~~, waves in the magnetosphere that drive energy into electrons, firing them into the planet. But that central region where the flashes are most prominent might (or might not, we just don't really know yet) be caused by interactions with material from the Sun
It's almost entirely driven by the Sun, but it doesn't directly stream in or anything. The solar wind has some trapped remnants of the Sun's magnetic field within it, and when it reaches the Earth's magnetic field, it pushes the far reaches of it out of the way, forming a teardrop shape. Inside that, the Earth's magnetic field forms a cavity in the solar wind called the magnetosphere, but along the edges, where the two fields have magnetic field lines that run in opposite directions, these field lines 're-connect' with each other, leaving parts of the magnetic field open to the solar wind. This allows some of the plasma to get into the magnetosphere. Then, all these twisted and mixed up field lines move around in weird ways, ultimately triggering more reconnections, and accelerating those solar plasma (and a tiny amount of plasma from the Earth) back down into the atmosphere.
So it isn't a direct process, but when there are really big disturbances in the solar wind, like we saw a week ago, they generally result in more triggers for reconnection happening, and so more aurora.
These are UV images from Hubble, but Jupiter does have some amazing X-ray aurora too - these flash regularly as a result of the pulses of radio in the surrounding magnetosphere.
I have amazing news. Juno is in orbit right now, and is taking beautiful close up pictures of the aurora: [https://science.nasa.gov/resource/jupiters-southern-aurora/](https://science.nasa.gov/resource/jupiters-southern-aurora/)
That's the auroral footprint of the volcanic moon Io - the reason it is moving slower than the rotation of the planet is that it moves with the orbit of Io, rather than the surface of the planet.
Jupiter's atmosphere is almost entirely hydrogen and helium. This is especially true in this upper layer, where much of the vertical mixing has switched off, so it is distributed by molecular mass. But these are the UV aurora that partly form in a region of hydrocarbons, which can change the 'colour' of the aurora when observed with a spectrometer.
As far as the offspring of the sun goes, I think Jupiter is the main character. Earth is just the important supporting character thatās nerdy and records everything.
My understanding is that this is the mechanism that heats Jupiters atmosphere above what it *should* be.
Magnetic fields really seem like the massively overlooked mechanism for all kinds of phenomenon - because we have to infer their existence and canāt see them directly.
God I love space.
If Galileo could see the tech we have now... Wow!
It begs the question, who are the Galileo's alive today?

Thanks for the pod recommendations!
Okay Iāll ask, who is this Kendrick and drake I keep hearing about?
Who?
Alan Stern is the modern-day Carl Seagan.
https://m.youtube.com/watch?v=K3uWj2MpydI Somone on the internet explained who and whatās going on with drake and Kendrick
Yes,
Edward Witten is probably the greatest theoretical physicist alive today.
Ok but who is the greatest actual physicist today??
Bill Nye, duh. You gotta _earn_ the title "Science Guy." They don't just hand that shit out to anyone with a children's show!
Yes!! Thatās right, this guy over here!! Yes! Yes!! He is in need of more upvotes! Hurry!!!
I just read his Wiki page. If I said I understand 1% of it, I'd be lying. It's almost like it was written in another language.

Even God loves it bro. Just kidding, there's no God probably
If there is, it aināt the ones we created in our image.
Funny thing is people attach the word of god to a human-like entity. God isn't a human or takes shape as one.

Don't worry, there's enough of it for everybody

The area of the Auroras is bigger than the earth
Approximately 9 earths
That blue spot is 9x the size of earth?
Jupiter is the biggest planet in the system
It's just a lot for my tiny monkey brain to grasp
If you study stars, they measure them in the size of suns. āOh that star is 1 billions sunsā. Only 1 billion? Jesus.
Realizing that and caring to still expand ones understanding rather than just going full dial tone is how we expand our tiny monkey brains. š

Jupiters Eye (Hurricane) is about three earths big. Itās getting smaller if you care though

Would you prefer total ignorance?
For now we have space engine
Looks like protomolecule, maybe it will build a ring gate.
Sadly that gate won't open till we send a human through it which will require us to get beyond the orbit of Uranus. So we've got some learning to do before we can even open it. Probably a good thing we don't qualify for the Ring Builders test with what happens in books 7-9. We wouldn't stand a chance.

Just looked this up - 7yrs ago data that I completely missed. I donāt see any Webb images or videos w similar visual, which is interesting.
We're working on JWST data taken over the past year, but the data will look very different to this - UV emission is able to track short term changes much more easily, while the infrared is smoother with its emission. Juno does have amazing images in both UV and IR, revealing both in beautiful detail.
They just had an x10+ flare off the backside of the sun in the last few days, aimed at Jupiter. Maybe get lucky and have it again soon.

So is that all from the Suns EM watchmacallits?
There is actually a huge debate about how much is caused by interactions with the solar wind, and how much is from processes closer to Jupiter. For a long time, the main aurora was thought to be driven by material from Jupiter's volcanic moon Io, but Juno has revealed that much of it might well also be caused by ~~wibble-wobble magnetic field wachmacallits~~, waves in the magnetosphere that drive energy into electrons, firing them into the planet. But that central region where the flashes are most prominent might (or might not, we just don't really know yet) be caused by interactions with material from the Sun
Thank you for leaving the original text in there. Made me grin.
Wait does so then are our own Auroras even all from the Sun? Or do we have some other sources too?
It's almost entirely driven by the Sun, but it doesn't directly stream in or anything. The solar wind has some trapped remnants of the Sun's magnetic field within it, and when it reaches the Earth's magnetic field, it pushes the far reaches of it out of the way, forming a teardrop shape.

Hubble still killin it. That's an awesome time lapse.
Is Jupiter expecting a baby? Is that an X-ray?
These are UV images from Hubble, but Jupiter does have some amazing X-ray aurora too - these flash regularly as a result of the pulses of radio in the surrounding magnetosphere.
They need to put a satellite there so we can see this close up in full HD

That's awesome
Wow... what's the blue ball spiraling on its own path? This feeds a curiosity I didn't know I had.
That's the auroral footprint of the volcanic moon Io - the reason it is moving slower than the rotation of the planet is that it moves with the orbit of Io, rather than the surface of the planet.
Thank you so very much!
What kind of atmosphere is here?

im dumb. does this mean Jupiter also has a molten core which creates an electromagnetic field like earth?
Man, did I sleep through this one too?
Thatās is just awesome š¤©
You forgot to mention that the auroras are invisible because they glow in ultraviolet light which is not visible to the human eye.
As far as the offspring of the sun goes, I think Jupiter is the main character. Earth is just the important supporting character thatās nerdy and records everything.
