    Jupiter is glowing in new pictures from NASA’s James Webb Space Telescope

    Jupiter is glowing in new pictures from NASA’s James Webb Space Telescope



    "Zoomed-out images show the planet’s faint rings and two moons, which scientists are analyzing to learn more about the planet.

    An early look at the view of Jupiter captured by NASA’s James Webb Space Telescope, or JWST, hinted at how precise and detailed our new view of the planet would be. But this week, NASA released another set of photos showing the cloud cover, rings, and moons of Jupiter in remarkable detail — and it was even better than scientists were hoping for.

    “We hadn’t really expected it to be this good, to be honest,” said planetary astronomer Imke de Pater, professor emerita of the University of California, Berkeley, in a press release. “It’s really remarkable that we can see details on Jupiter together with its rings, tiny satellites, and even galaxies in one image.”

    The telescope uses a camera with three filters that translate infrared light into colors that the human eye can see. The filter mapped to red colors shows Jupiter’s auroras, which shine off the planet’s poles. Light reflected from deep clouds appears in blues. And the planet’s weird atmospheric hazes show up in a filter of green and yellow. The planet’s famous Great Red Spot — an enormous storm bigger than Earth — is so bright that it appears white. The white streaks and spots are likely from reflected sunlight bouncing off particularly high-altitude clouds, NASA says.



    Taking the information from the JWST and translating it into processed, beautiful images was particularly difficult with Jupiter. The planet is much closer than more distant celestial objects and rotates comparatively quickly, said Judy Schmidt, a citizen scientist and the image processor for these new looks at the planet, in NASA’s press release. Schmidt and others had to combine several images to get these pictures of the gas giant.

    With these new images, Jupiter joins Stephan’s Quintet (a cluster of five galaxies), exoplanet WASP-96 b, the Southern Ring Nebula, and a handful of other cosmic characters who have already gotten their close-up with the JWST. And they’re just the start — there’s so much more to explore, and more images are coming soon."

    WE have been told by some sources for many years that differing climate change ( is solar system normal imo ) is happening within our system, so this may be a facet of that somehow.

    While it is true that all of the solar system is undergoing climatic changes (due to the sun), the difference in the images now is simply the result of having a better telescope, Vern.

    The James Webb telescope can see things never seen before with the older telescopes. But there is some optical distortion, in the form of the colors. The colors seen here are different from what the naked eye sees due to the fact that the James Webb telescope includes infrared and near-infrared light, which the human eye cannot see, and in order to make those colors visible in the photographs, they had to adjust the color profile, which makes all other colors look a bit weird now.

    Still, it's spectacular, though, and definitely progress on account of being able to study other planets, stars and galaxies.

    Ta Frank, so we know not for certain what eggyzackally was there before but do know for certain now and it may be the same as it was but not certain.

    improovments are good indeed.

    Maybe at some point in the future, there will be an even more powerful telescope that can show us even more.

    The universe is incredibly vast and mysterious, and there is so much more to discover. For instance, we still don't really know what dark matter and dark energy are — all we know is that they exist, because we can see their effects on the movement of stars and galaxies.

    One theory — which I myself have also already come up with a number of years ago — is that our entire universe would actually be the inside of a black hole, and that galaxies are moving farther away from us because we are being accelerated toward the center of the singularity faster than they are. But if that is true, then what is there outside of the black hole beyond its event horizon, and what will happen if or when we finally reach the core of the singularity? And what about the black holes inside of our own universe? Are they perhaps portals to another universe, where the laws of physics might be different?

    Those are all things we know nothing about yet, and the math constantly needs to be updated to reflect the new observations, because the math is only a language for describing the things we cannot see or even test.

    But what is remarkable is that we are now all living at exactly the right moment to be able to ask ourselves those very questions, because in about 20 billion years or so, the other galaxies will have all moved too far away from us to still be able to see them — the universe is expanding faster than the speed of light, so the light from those galaxies will by then never reach us anymore — and then for all we know, nothing else exists outside of our own galaxy, prompting us to have a very different view on what constitutes the universe and where it ends.

    In terms of studying the cosmos, we are now living in the Goldilocks era.

    That's a wild theory! It turns on its ear the conventional thinking that it's the stars farthest away from us accelerating away ever faster, when actually, it would be us accelerating away from them at an ever increasing rate.

    Assuming this be the case for the sake of discussion, what about the galaxies that are closer to the singularity than us? Seems we'd be seeing galaxies farther out moving away from us because we're accelerating inward faster than them, but the ones ahead of us would also appear to be accelerating away from us, but in this case, it's because they're accelerating inward faster than us.

    Everyone would be seeing separation, no matter of location, nothing's ever getting closer to anything else. Regardless of the reason, isn't that how the Doppler effect is currently viewed?

    Hmmmmmm...

    Yes, that is correct, but I'm not the only one who has come up this idea. For one, James Beacham posited the same idea in a video I posted in June of this year, and I've heard other scientists describe things that way as well.

    Considering that the universe appears to be expanding at an accelerating rate and that the observable universe is only that which we can still see at the farthest distance because its light is still underway to us (but redshifted), one could consider this boundary of the observable universe to be the event horizon of a black hole.

    Things crossing over inward of the event horizon of a black hole begin accelerating toward the center, but with such rapid acceleration that everything seen from the vantage of an observer who falls into the black hole appears to be accelerating away from them. The difference in gravitational pull — read: the acceleration due to the spacetime distortion — over a short distance would even be so drastic that the observer is becoming spaghettified, i.e. there would be significantly more gravity at the location of their feet than at the location of their head, and so they would be drawn into a strand of human spaghetti.

    Yes, the Doppler effect redshifts everything that's moving away from us at high speed, and blueshifts everything that's moving toward us at high speed.

    At present time, some galaxies — most notably the nearby ones, i.e. Andromeda (M31) and Triangulum (M33) — are blueshifted and moving toward us, at approximately 110 km per second (or approximately 68 miles per second), and will ultimately collide and merge with the Milky Way. But that's still not going to happen for about 4.5 to 5 billion years, because they are currently both between approximately 2.5 and 2.6 million light-years away from us, Andromeda being the closest of the two.

    That sounds more in line with traditional thought I've always heard about black holes, that the affects of being in one aren't at all pleasant, so how does being spaghettified (is that a word?) square with this nice existence we enjoy?

    I should have been more clear. I know about the red shift/blue shift, by saying "currently viewed", I meant if everything is separating from everything else, no matter of location anywhere out there in the known universe, one would always observe a red shift coming from other galaxies.

    How are some coming towards us under the black hole scenario?

    Well, it's all about the size, I guess. If our universe is indeed a black hole, then it's a black hole with at the very least a diameter of about 93 billion light-years, if not more. And it's almost 14 billion years old, or translated into the potential scenario of the universe being a black hole, we've been free-falling toward the singularity for 14 billion years already, and there's no telling when we'll hit it, but then presumably it's still way too far away from us to have a spaghettifying effect on us — and yes, it's a word, albeit one that was created by the science community.

    Not if they are moving toward us in a lateral direction compared to the direction of the free-fall toward the singularity. From our perspective, they would then be blueshifted. Which they are.

    The gravitational pull between the Milky Way and the two other galaxies. Even if the universe is not a black hole, then the gravitational pull between them still applies. The Milky Way, Andromeda and Triangulum are the three biggest galaxies in what is called the local cluster — there are yet a few dwarf galaxies nearby as well, and they will ultimately also get merged into the remaining galaxy after the merger of the big three, or perhaps even before that, by merging with one of the other two.

    The combined mass of all the stars, black holes, planets, moons and asteroids in each of the galaxies of the local cluster is big enough to sufficiently warp the spacetime around and between them to the extent that the galaxies in the local cluster are all being drawn to each other by gravity.
