Speaking of dust clouds. Anyone got idea why 3i/atlas doesn't contain any fine dusts but only millimeters to 1/10th of meter (4 inches) sized dusts as reported by a peer reviewed paper by the American Astronomical Society. How can outgassing occur witnout any fine dusts...

My goal is to learn the actual physics and technical stuff so i can prove it is natural object. Because so many ignorant out there who are not familiar with technical stuff so they are swayed otherwise especially knowing the universe is so old and our solar system so young so there should be...

I tried to google illustrations about extreme negative polarizations. I couldn't find one where it is illustrated fully. I found one of these in the few images. Let us go to the typical polarization example for my questions: When you mentioned "scattering plane". It is like the above plane...

Thanks. An example to determine if I got the idea. Supposed I have a truck that is light green in color. And supposed it has special adjustable surface metamaterial that you can tune the polarization to different values. If I create same setting as 3i/Atlas. Would the truck still be light green...

The separate concern is the methane. How can methane hide inside the ice and not get released last August 6. It is only released last December. So I want example of another comet where the methane hides inside and get release much later. Or if this is the first for any comet. Usually all...

I mean the methane part. If the outer most layer of methane was depleted in previous heating in another solar system, and no methane in one layer (this was why no methane detected last August 6 but only CO2). And now methane again (December). So the methane was kept in compartments or layers. I...

Thanks. About Methane in the first paper. Can you mention other comets where release of chemicals was regulated. Pre-perihelion Webb observations from August 2025 (as reported here) found that 3I/ATLAS is unusually rich in carbon-dioxide (CO2) relative to water (H2O) carrying 87% versus 4% of...

Can the James Webb Space Telescope 5–28 µm spectra spectrometer detect all substances and gases? If not, what specific substances can it detect? In the following James Webb chemical inventory analysis of comet 3i/Atlas: https://arxiv.org/pdf/2601.22034 They detected Co2, Co, Methane, Nickel in...

Does anyone know of a 4G/LTE sos/panic button, one where you can insert a simm and put the number where it can call when a button is pushed? Not just SMS but call because SMS has delays. There is a fence and a small building in the path which can block any wireless bell unit or even wireless...

I changed the illustration because it was done by someone hastily and wrong. The following is right illustration: The following are the references I found (the first two are before perihelion and the last after Perihelion. The Hubble team and James Webb team will publish the full data next...

The image was drawn by an artist just illustrating 1 of the 18 anomalies. That paper was about pre-perihelion which occurs before Oct 29, 2025. But after Perihelion, the same phenomenon occurs, So either the orientation moved with respect to sun or it flips at 180 degrees during perihilion. The...

What url can you see the computational detail or NASA mentioning 3i/Atlas going to pass by Jupiter HIll Radius?

[Mentor Note: OP advised that his acceptable reference in this OP does not support his assertions, and his references in subsequent posts are not acceptable per the PF rules. They have been requested to post acceptable references that support their assertions.] I want to know the classical...

Can someone please compute it. I don't know how to use them. If the Hill Radius is 53.5 million from Jupiter. I want to know if 3i/Atlas will pass say 53.55 or 53.45 million kilometers from Jupiter or slightly inside or outside the Hill Radius.
