Juno Observations of Io's Alfvén Wing From 23 Io Radii: agupubs.onlinelibrary.wiley.co -> "On 13 June, day 165 of 2024, Juno passed through Io's main #Alfvén wing at a distance of ∼23 #Io radii south of the moon during perijove 62. Evidence for this passage was clearly seen in the #Juno plasma wave, magnetometer, and plasma data. The plasma wave signature was an intensification of quasi-electrostatic waves below about 1 kHz with a weaker magnetic component, all lasting for about two minutes. A strong perturbation of the magnetic field consistent with strong field-aligned currents was observed at the edges of the Alfvén wing. Ions in the range below about 1 keV/q were slowed within the Alfvén wing. As with other measurements in Io's Alfvén wing, we observe evidence of filamentation. The power in the Alfvén wing based on the measured Poynting flux is estimated to be ∼500–1,500 × 109 W."

@stroughtonsmith 🧵Knowledge Navigator Persona

A VisionOS AI persona in a frame on a wall (or on your desk). In real life, not just in VisionOS!

KN listens and watches you, responds verbally, or directs its response to one of your screens, but lives in the frame.

Knowledge Navigator, but centered on a Google Beam quality persona. 🤖

This was my guess — and wish — for what Jony and Sam might try doing together.🙂

Io’s Missing Magma Ocean

In the late 1970s, scientists conjectured that Io was likely a volcanic world, heated by tidal forces from Jupiter that squeeze it along its elliptical orbit. Only months later, images from Voyager 1’s flyby confirmed the moon’s volcanism. Magnetometer data from Galileo’s later flyby suggested that tidal heating had created a shallow magma ocean that powered the moon’s volcanic activity. But newly analyzed data from Juno’s flyby shows that Io doesn’t have a magma ocean after all.

The new flyby used radio transmission data to measure any little wobbles that Io caused by tugging Juno off its expected course. The team expected a magma ocean to cause plenty of distortions for the spacecraft, but the effect was much slighter than expected. Their conclusion? Io has no magma ocean lurking under its crust. The results don’t preclude a deeper magma ocean, but at what point do you distinguish a magma ocean from a body’s liquid core?

Instead, scientists are now exploring the possibility that Io’s magma shoots up from much smaller pockets of magma rather than one enormous, shared source. (Image credit: NASA/JPL/USGS; research credit: R. Park et al.; see also Quanta)

What in the world is going on with the collaboration between Jony Ive's design company, io, and OpenAI? Over the weekend, all promotional material relating to the AI-centric device they are working on was pulled. @Mashable reports that it was to do with a trademark lawsuit filed by a company, IyO Inc, which makes earbuds with AI capabilities. Here's more.

Mashable · OpenAI and Jony Ive deal still on as ChatGPT owner scrubs io brandingPar Cecily Mauran

Sam Altman and Jony Ive say their first product together won’t be a phone, or glasses, or wearable tech. It will be fully aware of its environment and its user’s activities. It likely won’t come with a display as the pair said one of their goals is to wean people off screens. They want to keep people guessing in order to stave off competition. And they plan on shipping 100 million late next year.
What we do know is this: You have to give Altman and Ive credit for creating a buzz. Read more at @Engadget. #OpenAI #SamAltman #JonyIve #io #Tech #Technology flip.it/uabIfS

[Observer #Io depuis le #PicDuMidi ?] Connue pour son #volcanisme actif et intense, la lune Io de #Jupiter éjecte chaque seconde une tonne de gaz ionisé composé d’atomes de soufre, d’oxygène et de sodium, enrichissant de #plasma la magnétosphère jovienne.

Les tores de gaz et de plasma d'Io sont facilement observables depuis la Terre avec un petit #télescope muni d’un #coronographe capable d’atténuer la lumière provenant de Jupiter. S'ensuit l'idée de mettre en place un réseau en longitude - notamment de petits télescopes au sommet du Pic du Midi afin de suivre l'évolution de l'activité volcanique à la surface d'Io ainsi que des tores de gaz et de plasma ...

"What has happened is that the British government announced plans to cede control of the Chagos Islands, which is a territory in the British Indian Ocean that the British government has controlled since 1814. Should that happen, the British Indian Ocean Territory could wind up no longer existing, and the two-letter country code, IO, would cease to exist."

Here is a gorgeous image of Io taken by the NASA Juno spacecraft on Dec 30, 2023 from a distance of 4,262 km.

I added approx. latitude and longitude info and the names of a few prominent volcanic depressions known as Paterae. Juno's image of Io covers the northern hemisphere with the area from longitude 0° to 90° basking in the Sun's rays.

Please take a look at fosstodon.org/@AkaSci/11167569 for some more info on Io.
