The huge camera sensor array technology fascinates me. I wonder if an orbital spherical version could be made for 360x360 degree sky surveys? Maybe have some placed around the solar system, at different points of the axis plane? Just imagine what we could find zipping around. |

I’ve seen its gas cloud was around half the diameter of the sun. My quick googling and math says that’s under half a million miles. Its closest approach to Mars is around 18.5 million miles. |

Oversized coma as it rammed into the solar wind, odd color, odd elements in said coma, etc. OTOH, now we're getting into the profound problems in physics, such as why the entire Universe didn't annihilate itself in a 50/50 matter/antimatter reaction immediately after it came into being, and, well...a bunch of shit after that.

Oh that’s right the government shutdown is happening and hitting NASA at a critical time. What other agencies have Mars orbiters that can see this? And, I saw that delta shaped sun photo. I don’t know if thats real or not. My default assumption is that this is an interstellar “comet” of some kind.

I guess the most important question was answered - would it break up on far side of sun, and the answer to that is "nope" so what it is is strange yet. |

Jet detection on interstellar comet 3I/ATLAS with the Two-meter Twin Telescope We report a faint jet detected in deep g-band images of the interstellar comet 3I/ATLAS, also known as C/2025 N1 (ATLAS), obtained with the Two-meter Twin Telescope at Teide Observatory during the night of 2 August 2025 (UT). Between 21:18 and 00:16 UT, a total of 159 individual exposures of 50s each in the g band were acquired and co-added following the apparent motion of the object and centered on the comet optocenter. A Laplace-filtered image of the central coma of 3I/ATLAS, obtained following the method described by Serra-Ricart & Licandro (2015, ApJ, 814, 49), shows a faint jet at a position angle (PA) of 286.9+- 0.9 degrees (purple line), coincident with the broad, sunward-directed plume detected in visible images along PA = 280 +- 10 degrees (ATel #17350). The PA of the detected jet was measured at a projected distance of 6000 km from the comet optocenter (indicated by the red lines). The projected velocity vector of the comet (blue arrow) and the antisolar direction (yellow arrow) are also shown, together with the image orientation and a distance scale.

If so, the camouflage is working very well since all we can really say is "it's probably a comet even though it's doing a bunch of shit we've never seen comets do, but still probably a comet, just a weird comet". |

Rogan made a comment regarding 3iAtlas and I'm paraphrasing: "I want to meet the most advanced aliens that can teleport and shit, not a bunch of space Vikings who are riding on a big rock looking for somewhere to pillage." It's a big ol' universe and assuming every civilization capable of space travel is going to be equally capable is, to quote a well-known Vulcan, illogical. |

It's not like we have a bunch to choose from. I mean with the possibility of the Bible being from us to us, (possibly at the encouragement of a different species if wanting to keep it as a unified theory.), that would make one well known interaction total. In all of history (well, in the past 8000 years), we made notes to ourselves of what to do and what not to do and then thought we knew better than the stupid us so they did the same thing in a slightly different way in a slightly different spot. No matter what they do, history keeps repeating itself. That's probably why we have all these pyramids around the world. That's the adolescent teenage emo angst version of us trying the exact same thing over and over, just in a different spot. |

She showed numerous photos of sites with tens of thousands of mud bricks all strewn around and the landscape certainly looks like someone excavated the area in antiquity. She postulated that the ancient Egyptians dug up several megalithic sites that were purposely buried by a previous culture and repurposed them, instead of the mainstream version that says the Egyptians built the structures and the mud bricks are just later renovations. She also said if that's the case, it could well be that the shitty mud brick pyramids were built just to cover an existing structure, which makes perfect sense given the tunnels and such that are underneath the piles of mud bricks and the megalithic interiors of some of the crappy pyramids. According to accepted dating, there's a 7,000 year gap between the construction of Gobekli Tepi and the Step Pyramid of Djoser (surprise, it's a megalithic structure covered by smaller stones). That's a massive shitload of time for a megalithic culture to spread out and build multiple other sites, even if one assumes Gobekli Tepi was their first build. We desperately need a time machine to figure out why the megalithic cultures buried their shit after spending all the time and effort on construction. Maybe they figured out a way to leave this planet and wanted to hide/protect their sites in case they returned, or they somehow knew shit was about to get bad and they had enough warning to bury their treasured structures. |

Quick "back to reality" question, as I haven't been following it lately (52+hour work week): Despite the "jets," has it slowed down or changed course in any significant manner? Or is it still on course to streak through our system at 130,000mph, in the same trajectory as it entered? |
