I AM SO HAPPY. It really made me feel depressed when I heard first about the failure of the antenna. I thought the whole reason to why we were going there was to get penetrative radar, and not this wouldnt be the case.

Great space exploration report, thank you. It’s good news about Juice, and an incredible technical achievement to finally get the antenna free and working. Love the NASA snake ‘rover’, that could be an amazing success. Yes, got to keep a close eye on our own star at the center of our solar system, it is very turbulent at the moment, and could deliver another Carrington Event. I observe it regularly, through my own solar telescope, and it is pretty awesome to see solar prominences, filmant eruptions, jets, coronal holes, and all the activity in real time (the delay of 8 minutes and 20 seconds is nothing, when compared to observing objects outside our solar system!).

[@edwardrhoads7283]

The Eddington Limit only applies to stars that are held up by gravity. A brightness above the Eddington limit would cause the outward radiation pressure to exceed the force of gravity. The Eddington limit does not apply to explosions and/or shells of material flying outwards which are no longer bound by gravity.

[@MCsCreations]

About the rovers, Fraser, I always thought they should stop to reinvent the wheel and copy nature's solutions. 😬 (Sorry, I couldn't resist!) Funny but true story: once I wrote an article about the risks of a solar storm and so on... Then a guy from a Portuguese astronomy blog read it and wanted to k*ill me. 😬 He accused me of scaring the public and so on... Anyway, a friend of mine came to the rescue and asked him what part exactly I got it wrong... And, well, he never complained about it again! 😂 Anyway, stay safe there with your family! 🖖😊

[@extropian314]

2:09 And more good news is that it's the slow-moving *CME* that sometimes follows the flare, and not the flare, that does most of the worst damage that we commonly associate with solar storms. Bigger flares cause only some radio blackouts while bigger CMEs short-circuit electronics. And since CMEs are also pretty "focused", most CMEs are not aimed at Earth, while flares are more like flashlights, bathing a broad swath of space in X-rays. 😎

Silly question: How long is a month on Jupiter?

[@TheExplodingGerbil]

No such thing as a,silly question 😊. Do u mean how long are 30 days? Just trying to reframe it ❤

[@frasercain]

A month is a completely human-made concept, there's no natural event that marks its length. However, the closest analogy would be the orbit of the Moon, which takes 28 days. Io takes 42 hours to orbit Jupiter... so that?

[@rodvik]

I would go with 1 Jovian month = 361 earth days. Thats jupiters orbital period or "year" (11.86 Earth years) divided by 12. Obviously you can invent the jovian month however you like but that would be my stab. Fun game and question!! I imagine Jovian lunar calendars would be VERY complex with 95 (and counting) moons :) I wonder what a civilization or culture would be like with that kind of calendar(s). :)

[@Kaizen712]

As I understand it, the SME is ionized and interferes with electronics, like an electromagnetic pulse. This basically fries electronics. The counter to it is to place electronics into a faraday cage. (Metal enclosure that shorts inductive loads to ground.)

[@Inertia888]

@@Kaizen712 I am a lot more worried about the electrical grids. I wonder if we saw a big one coming, if we would be able to time it right, and shut down the correct grids, and if we would be able to save the systems from being damaged. Or would that even prevent damage? I hear a lot of different opinions on this, and I know there is some risk, but I don't know the details on how to, or if we even can prevent a very big CME from damaging the electrical grids.

[@archielundy3131]

Thanks Fraser for stating so clearly, contradictory data that challenges current theory is not a crises but a great opportunity. Unfortunately it's not a prevalent perspective among large swaths of the media.

We slapped and jiggled old television sets to get the picture to stabilize. Future space probes should always have a slapper and a jiggler. How fitting that no matter how far we've come, a good knock is an essential part of the toolkit.

[@frasercain]

You could never see it because your eyes can't make long duration exposures. Think about the beautiful pictures of Andromeda or the Milky Way. You're very close to both but they look like faint clouds from our perspective. You need your eyes to absorb photons for a few hours to be able to see that stuff.

I think it’s miscalculation of true focal lengths of our instruments. The dishes during day expand, bubbles focal length changed in micro gravity and had to be calibrated with additional lenses. Who knows what actual focal length of JWST became with adjustable mirrors. These fractions of difference in calculations, make a difference in 13.8 billion years. The tension.

Hi Frasier, Could an Earth-like planet orbiting a red dwarf star in a tidally locked orbit retain its atmosphere despite the large and frequent CMEs that occur on red dwarfs?

[@CrasyFingers]

does JUICE still have enough fuel to carry out the mission normally or are they skipping certain things?

[@tmarti69]

If we make time something then it solves our paradox of existence, asymptote, black holes, basic infinities, gravity, and simplicity. If time space creates a grid that can occupy itself to form new elements of energy and matter with quantum effects. Then it leaks into the past, moving the past slightly as the entanglement rhythms move forward. Enough energy is next to nothing at the beginning to create it, expand it. More rhythm exists as more energy and mass occupy the same time space grid, and if that entanglement is smaller than the grid, we call it: light, wave, particle, but if it is greater, or faster than the grid units, plankxels, we call that, mass, even gravity. One element is easier to create than many, no infinity is more conservative than infinity. So, if we consider simplicity, we have other forms of matter, antimatter, transference of energy from expansion through entanglements even evaporation of black holes.

CMEs effect large electrical systems much more than satellite or plane-sized systems. The telegraph lines that figured prominently during the Carrington Event were dozens to hundreds of km long. The reason you’ll want to disconnect your TV and PC is to guard against power spikes. In 1859 telegraph operators got a nasty shock. A spike like that today would cook microcircuits. The conductive traces in microcircuits aren’t long enough to build up enough charge but the power transmission lines are. Hopefully electric utility companies have equipment that will temporarily chop up their transmission lines.

It’s why we use loads of copper windings in motors and generators. Satellites are likely going to have wiring measuring a few hundred metres.
