Why Neptune looks like a ghost - with Dr. Heidi B. Hammel

[@LaunchPadAstronomy]

🔴 Meanwhile, there's a problem with Webb's Mid-Infrared Imager: kzbin.info/www/bejne/i4LQmGSanZiEhKs

[@zlm001]

One question it my video idea I had was if the massive satellite constellations could be also used to create some type of observatory. Like if they offered a small space in each one for a type of cheap, small detector. They probably have good clocks and are constantly communicating with lasers, so could a radio attenae combine the clock and position signal on each satellite for the constellation to detect very weak signals? What each detector packs in capability is compensated for by having 17,000 if them? Or instead of piggybacking on Internet satellites, what types of observations could be created with a satellite constellation type of observatory?

I love Heidi! She was great in the Voyager documentary "The Farthest." This made my evening.

[@ridhvikg]

I get excited whenever I see a new Launch Pad Astronomy video!!

[@LaunchPadAstronomy]

You're very kind

[@davelcx1958]

Thanks for another great episode and a super interesting interview with Dr. Heidi.

[@NeilGastonguay]

Mind bending information. Dr. Hummel is able to describe what we see with scientific accuracy that is accessible to a listener such as me, interested but having no background in such complex science. An excellent video.

[@Etopirynka]

It's so good to see and listen to someone so passionate about what they do ❤️

[@dogcarman]

True. This is how science should be communicated. Factual, to the point and with exuberance.

[@MrsTitina]

Heidi is just fantabulous!! Maybe you can invite her every now and then?? 😊

[@LaunchPadAstronomy]

Absolutely! She's been a guest on several of my livestreams and she's one of my favorite people in the world 🙂

[@boneybone8123]

It's amazing how crisp and clear Dr. Heidi B. Hammel pronounces every single word. Her speech is as intelligible as text, it must be a breeze to take notes in her class. Such clarity.

[@MaryAnnNytowl]

Webb has _just _*_blown us all_*_ away_ with every single image we see from it, so I can imagine how much it affects scientists working on those specific things seen with the JWST! Thank you for this interview. I need stuff to keep my mind occupied, with what I'm dealing with, and things like this are just the ticket. ❤️ I love the little JWST model she has on that table behind her, too, BTW! ❤️❤️

[@LaunchPadAstronomy]

Glad you enjoyed it, and glad it helps!

Really enjoyable interview (Parts 1 and 2) and fantastic insights of early data. Thank you.

[@JAGzilla-ur3lh]

I'm just a filthy, casual layman where astronomy is concerned, so I don't see much beyond pretty colors in these images. It's great to have scientists willing to break down the details and significance of what we're seeing, especially when they're this infectiously enthusiastic about it. I'm so glad this telescope is delivering what was hoped for after so many years in the making.

[@PronatorTendon]

Seeing the embedded moons is great, I hope we can eventually send probes to orbit all of the other planets so we can observe them in close to real time

[@di_avo]

Being more interested in our planets and nearby exoplanets.. I find this random injection of local discovery to be astounding. Like, we don’t necessarily need a multi $B project to discover new things about our own planets, we can simply point the lens at it and we have new data. I cannot wait for Enceladus and Pluto details to come down. I’m going to have to study my spectroscopy so I’m ready to understand the findings

[@probablynovideoshere]

I watch these videos 50% to learn about astronomy and 50% to see astronomers geek out about space :)

[@altaloma7789]

Sorry, but the two Voyagers were slightly different, but it wasn't obvious to most people's eyes. After the Voyager II launch, the science boom did not indicate full deployment. A mad scramble ensued at JPL, and the Voyager I boom actuators and folding struts were quickly modified, more than doubling their deployment torques. The cause of the anomaly was never certain, but it was believed that the cabling on the science boom may have interfered with the high gain antenna. Luckily, over time the fluid in the actuators froze, locking the boom(s) in place.

[@agschwend]

Dear Heidi, I totally geek out about spectra! Light carries so much information. I was always fascinated by this.

[@cavesalamander6308]

Thank you very much for this video. As I hear for the first time, deconvolution is indeed being used to process images from a telescope. This is interesting, because the first moment I saw pictures distorted by diffraction effects, I thought that the distortion could probably be corrected - and it really is being done! Is it possible to see and compare the original and corrected images? Can you describe the processing approach? After all, deconvolution taking into account diffraction effects is much more complicated than a 'simple' correction such as smearing of a moving object. What super-resolution with respect to the diffraction limit of the telescope was obtained?

[@Nedski42YT]

Christian, I have a production suggestion for Dr. Hammel. Could she decouple her webcam from the table top? Every touch of the table creates vertical movement in the video image. There's a great deal of moiré in the JWST scale models sunshield behind her that drives me crazy! Thanks.

Isn‘t the amount of data coming down from JWST just overwhelming, even for this huge science community waiting for it? Couldn‘t just this one image be enough to have a galaxy-guy (or gal!) working on for a year? Won‘t a lot of data just get lost because nobody can process and analyse it? Just wondering! Great video and much fun to feel the enthusiasm of Dr. Hammel.

[@rhoddryice5412]

Imagine recalibrating this image to the background galaxies. The amount of “collateral” data collected is almost as mind boggling as the universe it self.

[@dimas3297]

Have I missed it or there were no words about those two bright points on the rings, one on each ring, one on each side of the planet? Are they moonlets? Coinciding background galaxies or stars? Some other kind of ring features? I'm stunned that they were not mentioned at all!

[@bravo_01]

Hey! Perhaps those exact same methods could be used to discover rings around ExoPlanets too ?!?

[@herrbrahms]

If Heidi monitors this thread, I'd like to ask her how Neptune is so bright in the near IR, given that its surface temperature is a little colder than boiling LN2 on the Earth's surface at 77K. How can a 60K object be so bright when its blackbody radiation should emit at a nominal 85 microns?

[@GeoffMorrisdrive]

Neptune my favourite Planet, Pluto looks good as well, Pluto will always be a planet in my eyes.

[@bernardedwards8461]

Why are the rings so warm and glowing in the infra-red? And are the glowing blobs on the planet a peep into the warmer interior?

[@xyzct]

I have to assume the two "dolls" behind her are Neptune and Uranus.

[@brown2889]

I have always wondered if maybe Neptune and Uranus’s gas acts as a superfluid? At those temperatures. Zero pun intended. Seriously. Love the thoughts of that too. I mean if a Sun can become a Diamond for a time just hanging out there, large as a planet, why not?

[@supergsx]

Why are Webb's images of the planets so blurry?? It literally looks like somebody's fingerprints are all over the mirrors.

[@justexactlyperfectbrothersband]

I've been worried about you Christian, last I heard a wheel got stuck! Is it free again now? Anyway I just knew we'd see a transitive nightfall of diamonds, who'd have thought would be Venus?! Please could you ask Heidi back after her bonanza? She's fantastic!

Rings are an over-rated nothingburger. So what! There's so much more interesting science everywhere else in those images. I hate when people are dazzled by rings, either Saturn's or Neptune's, or any more tenuous ones. But they're just debris fields either of ice or rock. So what! If they weren't 'pretty' or if they didn't simply 'look cool' nobody would be talking about them so much. I feel they're just a sucker's distraction. Sorry. I know I'm in the minority. But I find rings of any planet or moon to be just totally uninteresting.

[@LaunchPadAstronomy]

I find rings interesting because they're telling us something about the evolution of planets and moons. But different folks have different scientific interests. Heidi is more into the atmospheres as well.

[@mickobrien3156]

@@LaunchPadAstronomy I hear you. But they're often regarded, even revered, as an entity to themselves. I support studying samples. Sure. But as a whole the ring as its own system or entity is not particularly interesting.

I’ve been saying since 2013 that it seems extremely obvious that all electrons and photons are in orbit with a dark matter particle. Based on Fermilab and other recent findings, I now think electrons are made of an electron neutrino entangled in orbit with a dark matter muon neutrino, explaining their erratic orbits around nuclei and explaining superposition and uncertainty. I think photons are a pair of electrons entangled in orbit together in apparent an axial or helical polarizable wave-like movement depending on the direction of their rotation as they travel. This explains the double slit experiment for example and the speed of the rotation explains electromagnetic wavelengths (and visible colors, etc).
