4 Massive Earthquakes · 2 Nuclear Detonations · #3IATLAS Spaceship Arrival Between end of October and January 2026, four earthquakes exceeding magnitude 7–10 will strike various regions across the world. Two nuclear detonations will occur and 3IATLAS—an interstellar starship (not a comet)—will arrive at Earth. 3IATLAS is a massive, brightly illuminated, nickel-plated, internally powered, manned interstellar starship. It originates from Planet Epsilon Eridani-C, escorted by five smaller star cruisers. Its mission: 1) To establish the first formal public contact with humanity; 2) To end the UFO cover-up; 3) To help Earth withstand and recover from natural and man-made disruptions expected between late October and January 31. Starship ATLAS carries 114 scientific, spiritual helpers, and teachers to assist humanity and guide the planet toward balance.

Hey @randallwcarlson, @AlchemyAmerican #AviLoeb: Here is the #3IATLAS .gif DIRECTLY from ESA’s website titled: "ExoMars_Trace_Gas_Orbiter_observes_comet_3I_ATLAS_GIF.gif". If you zoom in, at least to a regular guy like me, it seems clear as day, that you can see individual orbs rotating around some kind of energy source. To assist with illustrating this incredible capture, also attached, you'll find that I have taken the original .gif and strictly ONLY enlarged the capture from the .gif provided by ESA’s website, careful not to change ANY aspect ratio, so as not to morph or warp the capture, I also enlarged the .gif to center @3iAtlas onto the frame, and kept the object center frame, while taking care NOT to modify the image in ANY sort of way. I've also attached two screenshots from that blown up video to show the light-sources as to why I hypothesized that there are individual objects rotating around some kind of energy source. It's not a prank. It's not misinformation. The image isn't fake. Here is the original source: https://esa.int/Science_Exploration/Space_Science/ESA_s_ExoMars_and_Mars_Express_observe_comet_3I_ATLAS

Avi Loeb reveals that the Galileo Project is looking into whether 3I/ATLAS is alone. It will be interesting to see if they authenticate our findings that indeed 3I/ATLAS does have companions.

🚨 BREAKING: The latest on #3IATLAS 👁️ 1️⃣ ESA enhanced image (Oct 7) 2️⃣ First official ESA release — no tail visible 3️⃣ Mars Perseverance capture (Oct 2) Scientists confirm: 33 billion tons of pure nickel. No iron. Super-flat. Glowing from the front. It’s shedding plasma… forming a backward tail… and moving unlike any known comet. Whatever this is — it’s not ordinary. 🛸 #3IATLAS #ESA #NASA #Space #UFO

There are 8 known anomalies linked to 3I/ATLAS (according to Avi Loeb): 1. Massive size – Over 5 km wide, weighing an estimated 33 billion tons. 2. Strange jet – A forward jet of scattered sunlight 10x longer than it is wide, pointing toward the Sun. 3. Unusual composition – High in nickel, low in iron, with mostly carbon dioxide instead of water. 4. Extreme polarization – Light from the object shows strong negative polarization. 5. Perfect alignment – Its trajectory matches the ecliptic plane within 5 degrees (0.2% likelihood). 6. Suspicious timing – Arrived at a moment optimized to pass near Mars, Venus, and Jupiter (0.005% likelihood). 7. Directional coincidence – Aligned within 9 degrees of the 1977 “Wow! Signal” (0.6% likelihood). 8. Nickel & cyanide traces – Photos reveal possible signatures consistent with industrial nickel alloys and cyanide compounds.

🚨3I/ATLAS just passed Mars: ESA caught it on camera. A fuzzy white sphere drifting through the Martian sky. This is the closest view of an interstellar object ever captured from another planet. Let’s talk about what’s next. 🧵👇 #3IAtlas #ESA #Mars #NASA #InterstellarComet

Harvard scientist suggests comet #3IATLAS might be avoiding detection In recent days, comet 3IATLAS has become one of the most enigmatic objects in the sky. What began as a simple astronomical discovery in Chile has now turned into a mystery that unsettles even the most experienced scientists. Astrophysicist Avi Loeb from Harvard University, known for his theories on extraterrestrial life, has suggested something that sounds almost incredible: the comet might be avoiding detection by human telescopes. A Visitor That Seems to Have a Plan According to Loeb, 3IATLAS trajectory is unlike that of a typical comet. Its path appears carefully plotted as if someone designed it to traverse the solar system without drawing too much attention. Loeb explains that the object has avoided aligning with the Moon and Earth exactly at the moments when the most powerful telescopes were pointed at that region of space. It’s as if a car passes in front of a security camera just when it’s turned off. Some researchers believe it may not be a simple comet, but a camouflaged craft, designed to discreetly observe our cosmic neighborhood. The October 29 Enigma Loeb predicts that when 3IATLAS approaches the Sun in late October, we could get a definitive answer. If the object releases fragments or small probes, like a mothership deploying explorers, it could confirm a theory that until now seemed like pure science fiction. What If It’s Not Natural? The scientist estimates a 30–50% chance that the object does not have a natural origin. In that case, we might be looking at a technological structure disguised as a comet a kind of cosmic Trojan horse traveling through space while hiding its true nature. However the scientific community remains cautious. If it turns out to be just a comet, its approach to the Sun could make it shine brightly or even cause it to disintegrate. Constant Observation For now tracking of 3IATLAS is in the hands of the European Space Agency’s JUICE (Jupiter Icy Moons Explorer) probe, which will continue observing it over the coming months. Whether it is a spacecraft or an icy comet, its behavior remains a mystery. The only clear thing is that this interstellar visitor seems to have its own rhythm and perhaps, its own purpose.

LOOK CLOSELY PLEASE! 3I/ATLAS will soon be behind our Sun as seen from Earth on October 29. At that time, if there are any small spaceships docked onto 3I/ATLAS, they can easily "detach" from that fast-flying rock, "brake" using thrusters to half of their starting speed, then "ride" the remaining velocity all the way to Earth, where they will arrive in 3 months. We will not "see" them until they emerge from the glare of our Sun, in late November or December. Just like Clint Eastwood sneaks up on bad guys with the Sun behind him. What a series of "coincidences". 👽 Those are the main things that you need to know.

Preguntas Frecuentes sobre el Cometa 3I/ATLAS y Objetos Interestelares

Tus preguntas respondidas sobre este notable visitante cósmico

Sí. Observaciones independientes de la NASA, la ESA y ATLAS confirman que 3I/ATLAS muestra actividad cometaria genuina y sigue una trayectoria hiperbólica, prueba de que entró al Sistema Solar desde el espacio interestelar.
"3I" lo identifica como el tercer objeto interestelar descubierto, después de ʻOumuamua (1I) y Borisov (2I). "ATLAS" se refiere a la red de telescopios que lo detectó en julio de 2025.
No. Su aproximación más cercana es de aproximadamente 1.8 UA (≈270 millones de km), distancia segura con riesgo de impacto cero.
Se espera el perihelio entre el 29 y 30 de octubre de 2025, aproximadamente a 1.36-1.4 UA del Sol.
Los datos del Hubble sugieren un núcleo de entre 0.3 y 5.6 km de ancho, aunque el polvo y el gas dificultan la medición precisa.
Los espectros muestran firmas fuertes de CO₂, H₂O, CO y OCS, más volátiles que los cometas típicos del Sistema Solar.
Su actividad a ~2.9 UA indica hielos ricos en volátiles que se subliman inusualmente temprano, sugiriendo un origen en un sistema estelar más frío.
Sí. Observaciones de Gemini South y Hubble en agosto de 2025 confirmaron una cola de polvo y gas que se expande a medida que se acerca al Sistema Solar interior.
Existen algunas opiniones especulativas, pero no hay evidencia que lo respalde. El consenso científico es que 3I/ATLAS es un cometa interestelar natural.
Sí. En su brillo máximo a finales de octubre de 2025, debería ser visible con telescopios de 8 pulgadas o más.
Puedes rastrear su posición y órbita en vivo a través de TheSkyLive, actualizado usando datos de NASA JPL Horizons.
Reaparecerá a principios de diciembre de 2025 después de la conjunción solar mientras se aleja del Sol.
Mars Express y ExoMars TGO de la ESA observarán durante su aproximación a Marte en octubre de 2025, con JUICE continuando después de la conjunción.
3I/ATLAS muestra una emisión de vapor de agua inusualmente temprana y vigorosa incluso a ~2.9 UA, algo raramente visto en cometas. Su coma también es inusualmente rico en CO₂, y su trayectoria hiperbólica confirma que es interestelar, no ligado por la gravedad del Sol.
